The Math Behind Bitcoin - CoinDesk

d down, k up, everybody's a game theorist, titcoin, build wiki on Cardano, (e-)voting, competitive marketing analysis, Goguen product update, Alexa likes Charles, David hates all, Adam in and bros in arms with the scientific counterparts of the major cryptocurrency groups, the latest AMA for all!

Decreasing d parameter
Just signed the latest change management document, I was the last in the chain so I signed it today for changing the d parameter from 0.52 to 0.5. That means we are just about to cross the threshold here in a little bit for d to fall below 0.5 which means more than half of all the blocks will be made by the community and not the OBFT nodes. That's a major milestone and at this current rate of velocity it looks like d will decrement to zero around March so lots to do, lots to talk about. Product update, two days from now, we'll go ahead and talk about that but it crossed my desk today and I was really happy and excited about that and it seemed like yesterday that d was equal to one and people were complaining that we delayed it by an epoch and now we're almost at 50 percent. For those of you who want parameter-level changes, k-level changes, they are coming and there's an enormous internal conversation about it and we've written up a powerpoint presentation and a philosophy document about why things were designed the way that they're designed.
Increasing k parameter and upcoming security video and everybody's a game theorist
My chief scientist has put an enormous amount of time into this. Aggelos is very passionate about this particular topic and what I'm going to do is similar to the security video that I did where I did an hour and a half discussion about a best practice for security. I'm going to actually do a screencasted video where I talk about this philosophy document and I'm going to read the entire document with annotations with you guys and kind of talk through it. It might end up being quite a long video. It could be several hours long but I think it's really important to talk around the design philosophy of this. It's kind of funny, everybody, when they see a cryptographic paper or math paper, they tend to just say okay you guys figure that out. No one's an expert in cryptography or math and you don't really get strong opinions about it but game theory despite the fact that the topics as complex and in some cases more complex you tend to get a lot of opinions and everybody's a game theorist. So, there was enormous amount of thought that went into the design of the system, the parameters of system, everything from the reward functions to other things and it's very important that we explain that thought process in as detailed of a way as possible. At least the philosophy behind it then I feel that the community is in a really good position to start working on the change management. It is my position that I'd love to see k largely increased. I do think that the software needs some improvements to get there especially partial delegation delegation portfolios and some enhancements into the operation of staking especially.
E-voting
I'd love to see the existence of hybrid wallets where you have a cold part a hot part and we've had a lot of conversations about that and we will present some of the progress in that matter at the product updates. If not this October certainly in November. A lot of commercialization going along, a lot of things going on and flowing around and you know, commercial teams working hard. As I mentioned we have a lot of deals in the pipeline. The Wyoming event was half political, half sales. We were really looking into e-voting and we had very productive conversations along those lines. It is my goal that Cardano e-voting software is used in political primaries and my hope is for eventually to be used in municipal and state and eventually federal elections and then in national elections for countries like Ethiopia, Mongolia and other places. Now there is a long road, long, long road to get there and many little victories that have to begin but this event. Wyoming was kind of the opener into that conversation there were seven independent parties at the independent national convention and we had a chance to talk to the leadership of many of them. We will also engage in conversation with the libertarian party leadership as well and at the very least we could talk about e-voting and also blockchain-based voting for primaries that would be great start and we'll also look into the state of Wyoming for that as well. We'll you know, tell you guys about that in time. We've already gotten a lot of inquiries about e-voting software. We tend to get them along with the (Atala) Prism inquiries. It's actually quite easy to start conversations but there are a lot of security properties that are very important like end-to-end verifiability hybrid ballots where you have both a digital and a paper ballot delegation mechanics as well as privacy mechanics that are interesting on a case-by-case basis.
Goguen, voting, future fund3, competitive marketing analysis of Ouroboros vs. EOS, Tezos, Algorand, ETH2 and Polkadot, new creative director
We'll keep chipping away at that, a lot of Goguen stuff to talk about but I'm going to reserve all of that for two days from now for the product update. We're right in the middle, Goguen metadata was the very first part of it. We already have some commercialization platform as a result of metadata, more to come and then obviously lots of smart contract stuff to come. This update and the November update are going to be very Goguen focused and also a lot of alternatives as well. We're still on schedule for an HFC event in I think November or December. I can't remember but that's going to be carrying a lot of things related multisig token locking. There's some ledger rule changes so it has to be an HFC event and that opens up a lot of the windows for Goguen foundations as well as voting on chain so fund3 will benefit very heavily from that. We're right in the guts of Daedalus right now building the voting center, the identity center, QR-code work. All this stuff, it's a lot of stuff, you know, the cell phone app was released last week. Kind of an early beta, it'll go through a lot of rapid iterations every few weeks. We'll update it, google play is a great foundation to launch things on because it's so easy to push updates to people automatically so you can rapidly iterate and be very agile in that framework and you know we've already had 3500 people involved heavily in the innovation management platform ideascale and we've got numerous bids from everything. From John Buck and the sociocracy movement to others. A lot of people want to help us improve that and we're going to see steady and systematic growth there. We're still chipping away at product marketing. Liza (Horowitz) is doing a good job, meet with her two three-times a week and right now it's Ouroboros, Ouroboros, Ouroboros... We're doing competitive analysis of Ouroboros versus EOS, Tezos, Algorand, ETH2 and Polkadot. We think that's a good set. We think we have a really good way of explaining it. David (David Likes Crypto now at IOHK) has already made some great content. We're going to release that soon alongside some other content and we'll keep chipping away at that.
We also just hired a creative director for IO Global. His name's Adam, incredibly experienced creative director, he's worked for Mercedes-Benz and dozens of other companies. He does very good work and he's been doing this for well over 20 years and so the very first set of things he's going to do is work with commercial and marketing on product marketing. In addition to building great content where hope is make that content as pretty as possible and we have Rod heavily involved in that as well to talk about distribution channels and see if we can amplify the distribution message and really get a lot of stuff done. Last thing to mention, oh yeah, iOS for catalyst. We're working on that, we submitted it to the apple store, the iOS store, but it takes a little longer to get approval for that than it does with google play but that's been submitted and it's whenever apple approves it or not. Takes a little longer for cryptocurrency stuff.
Wiki shizzle and battle for crypto, make crypto articles on wiki great again, Alexa knows Charles, Everpedia meets Charles podcast, holy-grail land of Cardano, wiki on Cardano, titcoin
Wikipedia... kind of rattled the cage a little bit. Through an intermediary we got contact with Jimmy Wales. Larry Sanger, the other co-founder also reached out to me and the everpedia guys reached out to me. Here's where we stand, we have an article, it has solidified, it's currently labeled as unreliable and you should not believe the things that are said in it which is David Gerard's work if you look at the edits. We will work with the community and try to get that article to a fair and balanced representation of Cardano and especially after the product marketing comes through. We clearly explain the product I think the Cardano article can be massively strengthened. I've told Rod to work with some specialized people to try to get that done but we are going to work very hard at a systematic approval campaign for all of the scientific articles related to blockchain technology in the cryptocurrency space. They're just terrible, if you go to the proof of work article, the proof of stake or all these things, they're just terrible. They're not well written, they're out of date and they don't reflect an adequate sampling of the science. I did talk to my chief scientist Aggelos and what we're gonna do is reach out to the scientific counterparts that most of the major cryptocurrency groups that are doing research and see if they want to work with us at an industry-wide effort to systematically improve the scientific articles in our industry so that there are a fair and balanced representation of what the current state of the art are, the criticisms, the trade-offs as well as the reference space and of course obviously we'll do quite well in that respect because we've done the science. We're the inheritor of it but it's a shame because when people search proof of stake on google usually wikipedia results are highly biased. We care about wikipedia because google cares about wikipedia, amazon cares about wikipedia.
If you ask Alexa who is Charles Hoskinson, the reason why Alexa knows is because it's reading directly from the wikipedia page. If I didn't have a wikipedia page Alexa would know that so if somebody says Alexa what is Cardano it's going to read directly from the wikipedia page and you know and we can either just pretend that reality doesn't exist or we can accept it and we as a community working with partners in the broader cryptocurrency community can universally improve the quality of cryptocurrency pages. There's been a pattern of commercial censorship on wikipedia for cryptocurrencies in general since bitcoin itself. In fact I think the bitcoin article is actually taken down once back in, might have been, 2010 or 2009 but basically wikipedia has not been a friend of cryptocurrencies. That's why everpedia exists and actually their founders reached out to me and I talked to them over twitter through PMs and we agreed to actually do a podcast. I'm going to do a streamyard, stream with these guys and they'll come on talk all about everpedia and what they do and how they are and we'll kind of go through the challenges that they've encountered. How their platform works and so forth and obviously if they want to ever leave that terrible ecosystem EOS and come to the holy-grail land of Cardano we'd be there to help them out. At least they can tell the world how amazing their product is and also the challenges they're having to overcome. We've also been in great contact with Larry Sanger.
He's going to do an internal seminar at some point with with us and talk about some protocols he's been developing since he left wikipedia specifically to decentralize knowledge management and have a truly decentralized encyclopedia. I'm really looking forward to that and I hope that presentation gives us some inspiration as an ecosystem of things we can do. That's a great piece of infrastructure regardless and after we learn a lot more about it and we talk to a lot of people in ecosystem. If we can't get people to move on over, it would be really good to see through ideascale in the innovation management platform for people to utilize the dc fund to build their own variant of wikipedia on Cardano. In the coming months there will certainly be funding available. If you guys are so passionate about this particular problem that you want to go solve it then I'd be happy to play Elon Musk with the hyperloop and write a white paper on a protocol design and really give a good first start and then you guys can go and try to commercialize that technology as Cardano native assets and Plutus smart contracts in addition to other pieces of technology that have to be brought in to make it practical.
Right now we're just, let's talk to everybody phase, and we'll talk to the everpedia guys, we're going to talk to Larry and we're going to see whoever else is in this game and of course we have to accept the incumbency as it is. So, we're working with obviously the wikipedia side to improve the quality of not only our article but all of the articles and the scientific side of things so that there's a fair and accurate representation of information. One of the reasons why I'm so concerned about this is that I am very worried that Cardano projects will get commercially censored like we were commercially censored. So, yes we do have a page but it took five years to get there and we're a multi-billion dollar project with hundreds of thousands of people. If you guys are doing cutting-edge novel interesting stuff I don't want your experience to be the same as ours where you have to wait five years for your project to get a page even after government's adopted. That's absurd, no one should be censored ever. This is very well a fight for the entire ecosystem, the entire community, not just Cardano but all cryptocurrencies: bitcoin, ethereum and Cardano have all faced commercial censorship and article deletions during their tenure so I don't want you guys to go through that. I'm hoping we can prove that situation but you know you don't put all your eggs in one basket and frankly the time has come for wikipedia to be fully decentralized and liberated from a centralized organization and massively variable quality in the editor base. If legends of valor has a page but Cardano didn't have one until recently titcoin, a pornography coin from 2015, that's deprecated, no one uses it, has a page but Cardano couldn't get one there's something seriously wrong with the quality control mechanism and we need to improve that so it'll get done.

/r/Scams Common Scam Master Post

Hello visitors and subscribers of scams! Here you will find a master list of common (and uncommon) scams that you may encounter online or in real life. Thank you to the many contributors who helped create this thread!

If you know of a scam that is not covered here, write a comment and it will be added to the next edition.

Blackmail email scam thread: https://www.reddit.com/Scams/comments/jij7zf/the_blackmail_email_scam_part_6/
Some of these articles are from small, local publications and refer to the scam happening in a specific area. Do not think that this means that the scam won't happen in your area.

Spoofing

Caller ID spoofing
It is very easy for anyone to make a phone call while having any number show up on the caller ID of the person receiving the phone call. Receiving a phone call from a certain number does not mean that the person/company who owns that number has actually called you.
Email spoofing
The "from" field of an email can be set by the sender, meaning that you can receive scam emails that look like they are from legitimate addresses. It's important to never click links in emails unless absolutely necessary, for example a password reset link you requested or an account activation link for an account you created.
SMS spoofing
SMS messages can be spoofed, so be wary of messages that seem to be from your friends or other trusted people.

The most common scams

The fake check scam (Credit to nimble2 for this part)
The fake check scam arises from many different situations (for instance, you applied for a job, or you are selling something on a place like Craigslist, or someone wants to purchase goods or services from your business, or you were offered a job as a mystery shopper, you were asked to wrap your car with an advertisement, or you received a check in the mail for no reason), but the bottom line is always something like this:
General fraudulent funds scams If somebody is asking you to accept and send out money as a favour or as part of a job, it is a fraudulent funds scam. It does not matter how they pay you, any payment on any service can be fraudulent and will be reversed when it is discovered to be fraudulent.
Phone verification code scams Someone will ask you to receive a verification text and then tell you to give them the code. Usually the code will come from Google Voice, or from Craigslist. In the Google version of the scam, your phone number will be used to verify a Google Voice account that the scammer will use to scam people with. In the Craigslist version of the scam, your phone number will be used to verify a Craigslist posting that the scammer will use to scam people. There is also an account takeover version of this scam that will involve the scammer sending a password reset token to your phone number and asking you for it.
Bitcoin job scams
Bitcoin job scams involve some sort of fraudulent funds transfer, usually a fake check although a fraudulent bank transfer can be used as well. The scammer will send you the fraudulent money and ask you to purchase bitcoins. This is a scam, and you will have zero recourse after you send the scammer bitcoins.
Email flooding
If you suddenly receive hundreds or thousands of spam emails, usually subscription confirmations, it's very likely that one of your online accounts has been taken over and is being used fraudulently. You should check any of your accounts that has a credit card linked to it, preferably from a computer other than the one you normally use. You should change all of your passwords to unique passwords and you should start using two factor authentication everywhere.
Cartel scam
You will be threatened by scammers who claim to be affiliated with a cartel. They may send you gory pictures and threaten your life and the lives of your family. Usually the victim will have attempted to contact an escort prior to the scam, but sometimes the scammers target people randomly. If you are targeted by a cartel scam all you need to do is ignore the scammers as their threats are clearly empty.
Boss/CEO scam A scammer will impersonate your boss or someone who works at your company and will ask you to run an errand for them, which will usually be purchasing gift cards and sending them the code. Once the scammer has the code, you have no recourse.
Employment certification scams
You will receive a job offer that is dependent on you completing a course or receiving a certification from a company the scammer tells you about. The scammer operates both websites and the job does not exist.
Craigslist fake payment scams
Scammers will ask you about your item that you have listed for sale on a site like Craigslist, and will ask to pay you via Paypal. They are scamming you, and the payment in most cases does not actually exist, the email you received was sent by the scammers. In cases where you have received a payment, the scammer can dispute the payment or the payment may be entirely fraudulent. The scammer will then either try to get you to send money to them using the fake funds that they did not send to you, or will ask you to ship the item, usually to a re-shipping facility or a parcel mule.
Craigslist Carfax/vehicle history scam
You'll encounter a scammer on Craigslist who wants to buy the vehicle you have listed, but they will ask for a VIN report from a random site that they have created and they will expect you to pay for it.
Double dip/recovery scammers
This is a scam aimed at people who have already fallen for a scam previously. Scammers will reach out to the victim and claim to be able to help the victim recover funds they lost in the scam.
General fraudulent funds scams The fake check scam is not the only scam that involves accepting fraudulent/fake funds and purchasing items for scammers. If your job or opportunity involves accepting money and then using that money, it is almost certainly a frauduent funds scam. Even if the payment is through a bank transfer, Paypal, Venmo, Zelle, Interac e-Transfer, etc, it does not matter.
Credit card debt scam
Fraudsters will offer to pay off your bills, and will do so with fraudulent funds. Sometimes it will be your credit card bill, but it can be any bill that can be paid online. Once they pay it off, they will ask you to send them money or purchase items for them. The fraudulent transaction will be reversed in the future and you will never be able to keep the money. This scam happens on sites like Craigslist, Twitter, Instagram, and also some dating sites, including SeekingArrangement.
The parcel mule scam
A scammer will contact you with a job opportunity that involves accepting and reshipping packages. The packages are either stolen or fraudulently obtained items, and you will not be paid by the scammer. Here is a news article about a scam victim who fell for this scam and reshipped over 20 packages containing fraudulently acquired goods.
The Skype sex scam
You're on Facebook and you get a friend request from a cute girl you've never met. She wants to start sexting and trading nudes. She'll ask you to send pictures or videos or get on webcam where she can see you naked with your face in the picture. The scam: There's no girl. You've sent nudes to a guy pretending to be a girl. As soon as he has the pictures he'll demand money and threaten to send the pictures to your friends and family. Sometimes the scammer will upload the video to a porn site or Youtube to show that they are serious.
What to do if you are a victim of this scam: You cannot buy silence, you can only rent it. Paying the blackmailer will show them that the information they have is valuable and they will come after you for more money. Let your friends and family know that you were scammed and tell them to ignore friend requests or messages from people they don't know. Also, make sure your privacy settings are locked down and consider deactivating your account.
The underage girl scam
You're on a dating site or app and you get contacted by a cute girl. She wants to start sexting and trading nudes. Eventually she stops communicating and you get a call from a pissed off guy claiming to be the girl's father, or a police officer, or a private investigator, or something else along those lines. Turns out the girl you were sexting is underage, and her parents want some money for various reasons, such as to pay for a new phone, to pay for therapy, etc. There is, of course, no girl. You were communicating with a scammer.
What to do if you are a victim of this scam: Stop picking up the phone when the scammers call. Do not pay them, or they will be after you for more money.
Phishing
Phishing is when a scammer tries to trick you into giving information to them, such as your password or private financial information. Phishing messages will usually look very similar to official messages, and sometimes they are identical. If you are ever required to login to a different account in order to use a service, you should be incredibly cautious.

PSA: you did not win a giftcard: https://old.reddit.com/Scams/comments/fffmle/psa_you_did_not_win_a_gift_card/
Sugar scams
Sugar scammers operate all over the internet and usually come in two varieties: advance-fee scams where the scammer will ask for a payment from you before sending you lots of money, and fake check style scams where the scammer will either pull a classic fake check scam, or will do a "bill pay" style scam that involves them paying your bills, or them giving you banking information to pay your bills. If you encounter these scammers, report their accounts and move on.
Google Hangouts
Google Hangouts is a messaging platform used extensively by all kinds of scammers. If you are talking with someone online and they want you to switch to Hangouts, they are likely a scammer and you should proceed with caution.
Publishers Clearing House scams
PCH scams are often advance-fee scams, where you will be promised lots of money after you make an initial payment. You will never need to pay if you win money from the real PCH.
Pet scams
You are looking for a specific breed of puppy, bird, or other pet. You come across a nice-looking website that claims to be breeding them and has some available right now - they may even be on sale! The breeders are not local to your area (and may not even list a physical location) but they assure you they can safely ship the pet to you after a deposit or full payment. If you go through with the payment, you will likely be contacted by the "shipper" who will inform you about an unexpected shipping/customs/processing fee required to deliver your new pet. But there was never any pet, both the "breeder" and the "shipper" are scammers, typically operating out of Africa. These sites are rampant and account for a large percentage of online pet seller websites - they typically have a similar layout/template (screenshot - example)
If you are considering buying a pet online, some easy things to check are: (1) The registration date of the domain (if it was created recently it is likely a scam website) (2) Reverse image search the pictures of available pets - you will usually find other scam websites using the same photos. (3) Copy a sentence/section of the text from the "about us" page and put it into google (in quotes) - these scammers often copy large parts of their website's text from other places. (4) Search for the domain name and look for entries on petscams.com or other scam-tracking sites. (5) Strongly consider buying/adopting your pet from a local shelter or breeder where you can see the animal in person before putting any money down.
Thanks to djscsi for this entry.
Fake shipping company scams
These scams usually start when you try to buy something illegal online. You will be scammed for the initial payment, and then you will receive an email from the fake shipping company telling you that you need to pay them some sort of fee or bribe. If you pay this, they will keep trying to scam you with increasingly absurd stories until you stop paying, at which point they will blackmail you. If you are involved in this scam, all you can do is ignore the scammers and move on, and try to dispute your payments if possible.
Chinese Upwork scam
Someone will ask you to create an Upwork or other freelancer site account for them and will offer money in return. You will not be paid, and they want to use the accounts to scam people.
Quickbooks invoice scam
This is a fake check style scam that takes advantage of Quickbooks.
The blackmail email scam The exact wording of the emails varies, but there are generally four main parts. They claim to have placed software/malware on a porn/adult video site, they claim to have a video of you masturbating or watching porn, they threaten to release the video to your friends/family/loved ones/boss/dog, and they demand that you pay them in order for them to delete the video. Rest assured that this is a very common spam campaign and there is no truth behind the email or the threats. Here are some news articles about this scam.
The blackmail mail scam
This is very similar to the blackmail email scam, but you will receive a letter in the mail.
Rental scams Usually on local sites like Craigslist, scammers will steal photos from legitimate real estate listings and will list them for rent at or below market rate. They will generally be hesitant to tell you the address of the property for "safety reasons" and you will not be able to see the unit. They will then ask you to pay them a deposit and they claim they will ship you the keys. In reality, your money is gone and you will have no recourse.
Craigslist vehicle scams A scammer will list a vehicle on Craigslist and will offer to ship you the car. In many cases they will also falsely claim to sell you the car through eBay or Amazon. If you are looking for a car on Craigslist and the seller says anything about shipping the car, having an agent, gives you a long story about why they are selling the car, or the listing price is far too low, you are talking to a scammer and you should ignore and move on.
Advance-fee scam, also known as the 419 scam, or the Nigerian prince scam. You will receive a communication from someone who claims that you are entitled to a large sum of money, or you can help them obtain a large sum of money. However, they will need money from you before you receive the large sum.
Man in the middle scams
Man in the middle scams are very common and very hard to detect. The scammer will impersonate a company or person you are legitimately doing business with, and they will ask you to send the money to one of their own bank accounts or one controlled by a money mule. They have gained access to the legitimate persons email address, so there will be nothing suspicious about the email. To prevent this, make contact in a different way that lets you verify that the person you are talking to is the person you think you are talking to.
Digit wallet scam
A variation of the fake check scam, the scammer sends you money through a digital wallet (i.e. Venmo, Apple Pay, Zelle, Cash App) along with a message claiming they've sent the money to the wrong person and a request to send the money back. Customer service for these digital wallets may even suggest that you send the money back. However, the money sent is from a stolen credit card and will be removed from your account after a few days. Your transfer is not reversed since it came from your own funds.
Cam girl voting/viewer scam
You will encounter a "cam girl" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to go to their site and sign up with your credit card. They may offer a free show, or ask you to vote for them, or any number of other fake stories.
Amateur porn recruitment scam
You will encounter a "pornstar" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to create an adult film with hehim, but first you need to do something. The story here is usually something to do with verifying your age, or you needing to take an STD test that involves sending money to a site operated by the scammer.
Hot girl SMS spam
You receive a text from a random number with a message along the lines of "Hey babe I'm here in town again if you wanted to meet up this time, are you around?" accompanied by a NSFW picture of a hot girl. It's spam, and they'll direct you to their scam website that requires a credit card.
Identity verification scam
You will encounter someone on a dating/messaging/social media/whatever site/app, and the scammer will ask that you verify your identity as they are worried about catfishing. The scammer operates the site, and you are not talking to whoever you think you are talking to.
This type of scam teases you with something, then tries to make you sign up for something else that costs money. The company involved is often innocent, but they turn a blind eye to the practice as it helps their bottom line, even if they have to occasionally issue refunds. A common variation takes place on dating sites/dating apps, where you will match with someone who claims to be a camgirl who wants you to sign up for a site and vote for her. Another variation takes place on local sites like Craigslist, where the scammers setup fake rental scams and demand that you go through a specific service for a credit check. Once you go through with it, the scammer will stop talking to you. Another variation also takes place on local sites like Craigslist, where scammers will contact you while you are selling a car and will ask you to purchase a Carfax-like report from a specific website.
Multi Level Marketing or Affiliate Marketing
You apply for a vague job listing for 'sales' on craigslist. Or maybe an old friend from high school adds you on Facebook and says they have an amazing business opportunity for you. Or maybe the well dressed guy who's always interviewing people in the Starbucks that you work at asks if you really want to be slinging coffee the rest of your life. The scam: MLMs are little more than pyramid schemes. They involve buying some sort of product (usually snake oil health products like body wraps or supplements) and shilling them to your friends and family. They claim that the really money is recruiting people underneath you who give you a slice of whatever they sell. And if those people underneath you recruit more people, you get a piece of their sales. Ideally if you big enough pyramid underneath you the money will roll in without any work on your part. Failure to see any profit will be your fault for not "wanting it enough." The companies will claim that you need to buy their extra training modules or webinars to really start selling. But in reality, the vast majority of people who buy into a MLM won't see a cent. At the end of the day all you'll be doing is annoying your friends and family with your constant recruitment efforts. What to look out for: Recruiters love to be vague. They won't tell you the name of the company or what exactly the job will entail. They'll pump you up with promises of "self-generating income", "being your own boss", and "owning your own company." They might ask you to read books about success and entrepreneurs. They're hoping you buy into the dream first. If you get approached via social media, check their timelines. MLMs will often instruct their victims to pretend that they've already made it. They'll constantly post about how they're hustling and making the big bucks and linking to youtube videos about success. Again, all very vague about what their job actually entails. If you think you're being recruited: Ask them what exactly the job is. If they can't answer its probably a MLM. Just walk away.

Phone scams

You should generally avoid answering or engaging with random phone calls. Picking up and engaging with a scam call tells the scammers that your phone number is active, and will usually lead to more calls.
Tax Call
You get a call from somebody claiming to be from your countries tax agency. They say you have unpaid taxes that need to be paid immediately, and you may be arrested or have other legal action taken against you if it is not paid. This scam has caused the American IRS, Canadian CRA, British HMRC, and Australian Tax Office to issue warnings. This scam happens in a wide variety of countries all over the world.
Warrant Call
Very similar to the tax call. You'll get a phone call from an "agent", "officer", "sheriff", or other law enforcement officer claiming that there is a warrant out for your arrest and you will be arrested very soon. They will then offer to settle everything for a fee, usually paid in giftcards.
[Legal Documents/Process Server Calls]
Very similar to the warrant call. You'll get a phone call from a scammer claiming that they are going to serve you legal documents, and they will threaten you with legal consequences if you refuse to comply. They may call themselves "investigators", and will sometimes give you a fake case number.
Student Loan Forgiveness Scam
Scammers will call you and tell you about a student loan forgiveness program, but they are interested in obtaining private information about you or demanding money in order to join the fake program.
Tech Support Call You receive a call from someone with a heavy accent claiming to be a technician Microsoft or your ISP. They inform you that your PC has a virus and your online banking and other accounts may be compromised if the virus is not removed. They'll have you type in commands and view diagnostics on your PC which shows proof of the virus. Then they'll have you install remote support software so the technician can work on your PC, remove the virus, and install security software. The cost of the labor and software can be hundreds of dollars. The scam: There's no virus. The technician isn't a technician and does not work for Microsoft or your ISP. Scammers (primarily out of India) use autodialers to cold-call everyone in the US. Any file they point out to you or command they have you run is completely benign. The software they sell you is either freeware or ineffective. What to do you if you're involved with this scam: If the scammers are remotely on your computer as you read this, turn off your PC or laptop via the power button immediately, and then if possible unplug your internet connection. Some of the more vindictive tech scammers have been known to create boot passwords on your computer if they think you've become wise to them and aren't going to pay up. Hang up on the scammers, block the number, and ignore any threats about payment. Performing a system restore on your PC is usually all that is required to remove the scammer's common remote access software. Reports of identity theft from fake tech calls are uncommon, but it would still be a good idea to change your passwords for online banking and monitor your accounts for any possible fraud. How to avoid: Ignore any calls claiming that your PC has a virus. Microsoft will never contact you. If you're unsure if a call claiming to be from your ISP is legit, hang up, and then dial the customer support number listed on a recent bill. If you have elderly relatives or family that isn't tech savvy, take the time to fill them in on this scam.
Chinese government scam
This scam is aimed at Chinese people living in Europe and North America, and involves a voicemail from someone claiming to be associated with the Chinese government, usually through the Chinese consulate/embassy, who is threatening legal action or making general threats.
Chinese shipping scam
This scam is similar to the Chinese government scam, but involves a seized/suspicious package, and the scammers will connect the victim to other scammers posing as Chinese government investigators.
Social security suspension scam
You will receive a call from someone claiming to work for the government regarding suspicious activity, fraud, or serious crimes connected to your social security number. You'll be asked to speak to an operator and the operator will explain the steps you need to follow in order to fix the problems. It's all a scam, and will lead to you losing money and could lead to identity theft if you give them private financial information.
Utilities cutoff
You get a call from someone who claims that they are from your utility company, and they claim that your utilities will be shut off unless you immediately pay. The scammer will usually ask for payment via gift cards, although they may ask for payment in other ways, such as Western Union or bitcoin.
Relative in custody Scammer claims to be the police, and they have your son/daughtenephew/estranged twin in custody. You need to post bail (for some reason in iTunes gift cards or MoneyGram) immediately or the consequences will never be the same.
Mexican family scam
This scam comes in many different flavours, but always involves someone in your family and Mexico. Sometimes the scammer will claim that your family member has been detained, sometimes the scammer will claim that your family member has been kidnapped, and sometimes the scammer will claim that your family member is injured and needs help.
General family scams
Scammers will gather a large amount of information about you and target your family members using different stories with the goal of gettimg them to send money.
One ring scam
Scammers will call you from an international number with the goal of getting you to return their call, causing you to incur expensive calling fees.

Online shopping scams

THE GOLDEN RULE OF ONLINE SHOPPING: If it sounds too good to be true, it probably is.
Dropshipping
An ad on reddit or social media sites like Facebook and Instagram offers items at huge discounts or even free (sometimes requiring you to reblog or like their page). They just ask you to pay shipping. The scam: The item will turn out to be very low quality and will take weeks or even months to arrive. Sometimes the item never arrives, and the store disappears or stops responding. The seller drop-ships the item from China. The item may only cost a few dollars, and the Chinese government actually pays for the shipping. You end up paying $10-$15 dollars for a $4 item, with the scammer keeping the profit. If you find one of these scams but really have your heart set on the item, you can find it on AliExpress or another Chinese retailer.
Influencer scams
A user will reach out to you on a social media platform, usually Instagram, and offer you the chance to partner with them and receive a free/discounted product, as long as you pay shipping. This is a different version of the dropshipping scam, and is just a marketing technique to get you to buy their products.
Triangulation fraud
Triangulation fraud occurs when you make a purchase on a site like Amazon or eBay for an item at a lower than market price, and receive an item that was clearly purchased new at full price. The scammer uses a stolen credit card to order your item, while the money from the listing is almost all profit for the scammer.
Instagram influencer scams
Someone will message you on Instagram asking you to promote their products, and offering you a discount code. The items are Chinese junk, and the offer is made to many people at a time.
Cheap Items
Many websites pop up and offer expensive products, including electronics, clothes, watches, sunglasses, and shoes at very low prices. The scam: Some sites are selling cheap knock-offs. Some will just take your money and run. What to do if you think you're involved with this scam: Contact your bank or credit card and dispute the charge. How to avoid: The sites often have every brand-name shoe or fashion item (Air Jordan, Yeezy, Gucci, etc) in stock and often at a discounted price. The site will claim to be an outlet for a major brand or even a specific line or item. The site will have images at the bottom claiming to be Secured by Norton or various official payment processors but not actual links. The site will have poor grammar and a mish-mash of categories. Recently, established websites will get hacked or their domain name jacked and turned into scam stores, meaning the domain name of the store will be completely unrelated to the items they're selling. If the deal sounds too good to be true it probably is. Nobody is offering brand new iPhones or Beats or Nintendo Switches for 75% off.
Cheap Amazon 3rd Party Items
You're on Amazon or maybe just Googling for an item and you see it for an unbelievable price from a third-party seller. You know Amazon has your back so you order it. The scam: One of three things usually happen: 1) The seller marks the items as shipped and sends a fake tracking number. Amazon releases the funds to the seller, and the seller disappears. Amazon ultimately refunds your money. 2) The seller immediately cancels the order and instructs you to re-order the item directly from their website, usually with the guarantee that the order is still protected by Amazon. The seller takes your money and runs. Amazon informs you that they do not offer protection on items sold outside of Amazon and cannot help you. 2) The seller immediately cancels the order and instructs you to instead send payment via an unused Amazon gift card by sending the code on the back via email. Once the seller uses the code, the money on the card is gone and cannot be refunded. How to avoid: These scammers can be identified by looking at their Amazon storefronts. They'll be brand new sellers offering a wide range of items at unbelievable prices. Usually their Amazon names will be gibberish, or a variation on FIRSTNAME.LASTNAME. Occasionally however, established storefronts will be hacked. If the deal is too good to be true its most likely a scam.
Scams on eBay
There are scams on eBay targeting both buyers and sellers. As a seller, you should look out for people who privately message you regarding the order, especially if they ask you to ship to a different address or ask to negotiate via text/email/a messaging service. As a buyer you should look out for new accounts selling in-demand items, established accounts selling in-demand items that they have no previous connection to (you can check their feedback history for a general idea of what they bought/sold in the past), and lookout for people who ask you to go off eBay and use another service to complete the transaction. In many cases you will receive a fake tracking number and your money will be help up for up to a month.
Scams on Amazon
There are scams on Amazon targeting both buyers and sellers. As a seller, you should look out for people who message you about a listing. As a buyer you should look out for listings that have an email address for you to contact the person to complete the transaction, and you should look out for cheap listings of in-demand items.
Scams on Reddit
Reddit accounts are frequently purchased and sold by fraudsters who wish to use the high karma count + the age of the account to scam people on buy/sell subreddits. You need to take precautions and be safe whenever you are making a transaction online.
Computer scams
Virus scam
A popup or other ad will say that you have a virus and you need to follow their advice in order to remove it. They are lying, and either want you to install malware or pay for their software.

Assorted scams

Chinese Brushing / direct shipping
If you have ever received an unsolicited small package from China, your address was used to brush. Vendors place fake orders for their own products and send out the orders so that they can increase their ratings.
Money flipping
Scammer claims to be a banking insider who can double/triple/bazoople any amount of money you send them, with no consequences of any kind. Obviously, the money disappears into their wallet the moment you send it.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

/r/Scams Common Scam Master Post

Hello visitors and subscribers of scams! Here you will find a master list of common (and uncommon) scams that you may encounter online or in real life. Thank you to the many contributors who helped create this thread!

If you know of a scam that is not covered here, write a comment and it will be added to the next edition.

Previous threads: https://old.reddit.com/Scams/search?q=common+scams+master+post&restrict_sr=on
Blackmail email scam thread: https://old.reddit.com/Scams/comments/g8jqnthe_blackmail_email_scam_part_5//
Some of these articles are from small, local publications and refer to the scam happening in a specific area. Do not think that this means that the scam won't happen in your area.

Spoofing

Caller ID spoofing
It is very easy for anyone to make a phone call while having any number show up on the caller ID of the person receiving the phone call. Receiving a phone call from a certain number does not mean that the person/company who owns that number has actually called you.
Email spoofing
The "from" field of an email can be set by the sender, meaning that you can receive scam emails that look like they are from legitimate addresses. It's important to never click links in emails unless absolutely necessary, for example a password reset link you requested or an account activation link for an account you created.
SMS spoofing
SMS messages can be spoofed, so be wary of messages that seem to be from your friends or other trusted people.

The most common scams

The fake check scam (Credit to nimble2 for this part)
The fake check scam arises from many different situations (for instance, you applied for a job, or you are selling something on a place like Craigslist, or someone wants to purchase goods or services from your business, or you were offered a job as a mystery shopper, you were asked to wrap your car with an advertisement, or you received a check in the mail for no reason), but the bottom line is always something like this:
General fraudulent funds scams If somebody is asking you to accept and send out money as a favour or as part of a job, it is a fraudulent funds scam. It does not matter how they pay you, any payment on any service can be fraudulent and will be reversed when it is discovered to be fraudulent.
Phone verification code scams Someone will ask you to receive a verification text and then tell you to give them the code. Usually the code will come from Google Voice, or from Craigslist. In the Google version of the scam, your phone number will be used to verify a Google Voice account that the scammer will use to scam people with. In the Craigslist version of the scam, your phone number will be used to verify a Craigslist posting that the scammer will use to scam people. There is also an account takeover version of this scam that will involve the scammer sending a password reset token to your phone number and asking you for it.
Bitcoin job scams
Bitcoin job scams involve some sort of fraudulent funds transfer, usually a fake check although a fraudulent bank transfer can be used as well. The scammer will send you the fraudulent money and ask you to purchase bitcoins. This is a scam, and you will have zero recourse after you send the scammer bitcoins.
Email flooding
If you suddenly receive hundreds or thousands of spam emails, usually subscription confirmations, it's very likely that one of your online accounts has been taken over and is being used fraudulently. You should check any of your accounts that has a credit card linked to it, preferably from a computer other than the one you normally use. You should change all of your passwords to unique passwords and you should start using two factor authentication everywhere.
Boss/CEO scam A scammer will impersonate your boss or someone who works at your company and will ask you to run an errand for them, which will usually be purchasing gift cards and sending them the code. Once the scammer has the code, you have no recourse.
Employment certification scams
You will receive a job offer that is dependent on you completing a course or receiving a certification from a company the scammer tells you about. The scammer operates both websites and the job does not exist.
Craigslist fake payment scams
Scammers will ask you about your item that you have listed for sale on a site like Craigslist, and will ask to pay you via Paypal. They are scamming you, and the payment in most cases does not actually exist, the email you received was sent by the scammers. In cases where you have received a payment, the scammer can dispute the payment or the payment may be entirely fraudulent. The scammer will then either try to get you to send money to them using the fake funds that they did not send to you, or will ask you to ship the item, usually to a re-shipping facility or a parcel mule.
General fraudulent funds scams The fake check scam is not the only scam that involves accepting fraudulent/fake funds and purchasing items for scammers. If your job or opportunity involves accepting money and then using that money, it is almost certainly a frauduent funds scam. Even if the payment is through a bank transfer, Paypal, Venmo, Zelle, Interac e-Transfer, etc, it does not matter.
Credit card debt scam
Fraudsters will offer to pay off your bills, and will do so with fraudulent funds. Sometimes it will be your credit card bill, but it can be any bill that can be paid online. Once they pay it off, they will ask you to send them money or purchase items for them. The fraudulent transaction will be reversed in the future and you will never be able to keep the money. This scam happens on sites like Craigslist, Twitter, Instagram, and also some dating sites, including SeekingArrangement.
The parcel mule scam
A scammer will contact you with a job opportunity that involves accepting and reshipping packages. The packages are either stolen or fraudulently obtained items, and you will not be paid by the scammer. Here is a news article about a scam victim who fell for this scam and reshipped over 20 packages containing fraudulently acquired goods.
The Skype sex scam
You're on Facebook and you get a friend request from a cute girl you've never met. She wants to start sexting and trading nudes. She'll ask you to send pictures or videos or get on webcam where she can see you naked with your face in the picture. The scam: There's no girl. You've sent nudes to a guy pretending to be a girl. As soon as he has the pictures he'll demand money and threaten to send the pictures to your friends and family. Sometimes the scammer will upload the video to a porn site or Youtube to show that they are serious.
What to do if you are a victim of this scam: You cannot buy silence, you can only rent it. Paying the blackmailer will show them that the information they have is valuable and they will come after you for more money. Let your friends and family know that you were scammed and tell them to ignore friend requests or messages from people they don't know. Also, make sure your privacy settings are locked down and consider deactivating your account.
The underage girl scam
You're on a dating site or app and you get contacted by a cute girl. She wants to start sexting and trading nudes. Eventually she stops communicating and you get a call from a pissed off guy claiming to be the girl's father, or a police officer, or a private investigator, or something else along those lines. Turns out the girl you were sexting is underage, and her parents want some money for various reasons, such as to pay for a new phone, to pay for therapy, etc. There is, of course, no girl. You were communicating with a scammer.
What to do if you are a victim of this scam: Stop picking up the phone when the scammers call. Do not pay them, or they will be after you for more money.
Phishing
Phishing is when a scammer tries to trick you into giving information to them, such as your password or private financial information. Phishing messages will usually look very similar to official messages, and sometimes they are identical. If you are ever required to login to a different account in order to use a service, you should be incredibly cautious.
The blackmail email scam The exact wording of the emails varies, but there are generally four main parts. They claim to have placed software/malware on a porn/adult video site, they claim to have a video of you masturbating or watching porn, they threaten to release the video to your friends/family/loved ones/boss/dog, and they demand that you pay them in order for them to delete the video. Rest assured that this is a very common spam campaign and there is no truth behind the email or the threats. Here are some news articles about this scam.
The blackmail mail scam
This is very similar to the blackmail email scam, but you will receive a letter in the mail.
Rental scams Usually on local sites like Craigslist, scammers will steal photos from legitimate real estate listings and will list them for rent at or below market rate. They will generally be hesitant to tell you the address of the property for "safety reasons" and you will not be able to see the unit. They will then ask you to pay them a deposit and they claim they will ship you the keys. In reality, your money is gone and you will have no recourse.
Craigslist vehicle scams A scammer will list a vehicle on Craigslist and will offer to ship you the car. In many cases they will also falsely claim to sell you the car through eBay or Amazon. If you are looking for a car on Craigslist and the seller says anything about shipping the car, having an agent, gives you a long story about why they are selling the car, or the listing price is far too low, you are talking to a scammer and you should ignore and move on.
Advance-fee scam, also known as the 419 scam, or the Nigerian prince scam. You will receive a communication from someone who claims that you are entitled to a large sum of money, or you can help them obtain a large sum of money. However, they will need money from you before you receive the large sum.
Man in the middle scams
Man in the middle scams are very common and very hard to detect. The scammer will impersonate a company or person you are legitimately doing business with, and they will ask you to send the money to one of their own bank accounts or one controlled by a money mule. They have gained access to the legitimate persons email address, so there will be nothing suspicious about the email. To prevent this, make contact in a different way that lets you verify that the person you are talking to is the person you think you are talking to.
Cam girl voting/viewer scam
You will encounter a "cam girl" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to go to their site and sign up with your credit card. They may offer a free show, or ask you to vote for them, or any number of other fake stories.
Amateur porn recruitment scam
You will encounter a "pornstar" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to create an adult film with hehim, but first you need to do something. The story here is usually something to do with verifying your age, or you needing to take an STD test that involves sending money to a site operated by the scammer.
Hot girl SMS spam
You receive a text from a random number with a message along the lines of "Hey babe I'm here in town again if you wanted to meet up this time, are you around?" accompanied by a NSFW picture of a hot girl. It's spam, and they'll direct you to their scam website that requires a credit card.
Identity verification scam
You will encounter someone on a dating/messaging/social media/whatever site/app, and the scammer will ask that you verify your identity as they are worried about catfishing. The scammer operates the site, and you are not talking to whoever you think you are talking to.
This type of scam teases you with something, then tries to make you sign up for something else that costs money. The company involved is often innocent, but they turn a blind eye to the practice as it helps their bottom line, even if they have to occasionally issue refunds. A common variation takes place on dating sites/dating apps, where you will match with someone who claims to be a camgirl who wants you to sign up for a site and vote for her. Another variation takes place on local sites like Craigslist, where the scammers setup fake rental scams and demand that you go through a specific service for a credit check. Once you go through with it, the scammer will stop talking to you. Another variation also takes place on local sites like Craigslist, where scammers will contact you while you are selling a car and will ask you to purchase a Carfax-like report from a specific website.
Multi Level Marketing or Affiliate Marketing
You apply for a vague job listing for 'sales' on craigslist. Or maybe an old friend from high school adds you on Facebook and says they have an amazing business opportunity for you. Or maybe the well dressed guy who's always interviewing people in the Starbucks that you work at asks if you really want to be slinging coffee the rest of your life. The scam: MLMs are little more than pyramid schemes. They involve buying some sort of product (usually snake oil health products like body wraps or supplements) and shilling them to your friends and family. They claim that the really money is recruiting people underneath you who give you a slice of whatever they sell. And if those people underneath you recruit more people, you get a piece of their sales. Ideally if you big enough pyramid underneath you the money will roll in without any work on your part. Failure to see any profit will be your fault for not "wanting it enough." The companies will claim that you need to buy their extra training modules or webinars to really start selling. But in reality, the vast majority of people who buy into a MLM won't see a cent. At the end of the day all you'll be doing is annoying your friends and family with your constant recruitment efforts. What to look out for: Recruiters love to be vague. They won't tell you the name of the company or what exactly the job will entail. They'll pump you up with promises of "self-generating income", "being your own boss", and "owning your own company." They might ask you to read books about success and entrepreneurs. They're hoping you buy into the dream first. If you get approached via social media, check their timelines. MLMs will often instruct their victims to pretend that they've already made it. They'll constantly post about how they're hustling and making the big bucks and linking to youtube videos about success. Again, all very vague about what their job actually entails. If you think you're being recruited: Ask them what exactly the job is. If they can't answer its probably a MLM. Just walk away.

Phone scams

You should generally avoid answering or engaging with random phone calls. Picking up and engaging with a scam call tells the scammers that your phone number is active, and will usually lead to more calls.
Tax Call
You get a call from somebody claiming to be from your countries tax agency. They say you have unpaid taxes that need to be paid immediately, and you may be arrested or have other legal action taken against you if it is not paid. This scam has caused the American IRS, Canadian CRA, British HMRC, and Australian Tax Office to issue warnings. This scam happens in a wide variety of countries all over the world.
Warrant Call
Very similar to the tax call. You'll get a phone call from an "agent", "officer", "sheriff", or other law enforcement officer claiming that there is a warrant out for your arrest and you will be arrested very soon. They will then offer to settle everything for a fee, usually paid in giftcards.
[Legal Documents/Process Server Calls]
Very similar to the warrant call. You'll get a phone call from a scammer claiming that they are going to serve you legal documents, and they will threaten you with legal consequences if you refuse to comply. They may call themselves "investigators", and will sometimes give you a fake case number.
Student Loan Forgiveness Scam
Scammers will call you and tell you about a student loan forgiveness program, but they are interested in obtaining private information about you or demanding money in order to join the fake program.
Tech Support Call You receive a call from someone with a heavy accent claiming to be a technician Microsoft or your ISP. They inform you that your PC has a virus and your online banking and other accounts may be compromised if the virus is not removed. They'll have you type in commands and view diagnostics on your PC which shows proof of the virus. Then they'll have you install remote support software so the technician can work on your PC, remove the virus, and install security software. The cost of the labor and software can be hundreds of dollars. The scam: There's no virus. The technician isn't a technician and does not work for Microsoft or your ISP. Scammers (primarily out of India) use autodialers to cold-call everyone in the US. Any file they point out to you or command they have you run is completely benign. The software they sell you is either freeware or ineffective. What to do you if you're involved with this scam: If the scammers are remotely on your computer as you read this, turn off your PC or laptop via the power button immediately, and then if possible unplug your internet connection. Some of the more vindictive tech scammers have been known to create boot passwords on your computer if they think you've become wise to them and aren't going to pay up. Hang up on the scammers, block the number, and ignore any threats about payment. Performing a system restore on your PC is usually all that is required to remove the scammer's common remote access software. Reports of identity theft from fake tech calls are uncommon, but it would still be a good idea to change your passwords for online banking and monitor your accounts for any possible fraud. How to avoid: Ignore any calls claiming that your PC has a virus. Microsoft will never contact you. If you're unsure if a call claiming to be from your ISP is legit, hang up, and then dial the customer support number listed on a recent bill. If you have elderly relatives or family that isn't tech savvy, take the time to fill them in on this scam.
Chinese government scam
This scam is aimed at Chinese people living in Europe and North America, and involves a voicemail from someone claiming to be associated with the Chinese government, usually through the Chinese consulate/embassy, who is threatening legal action or making general threats.
Chinese shipping scam
This scam is similar to the Chinese government scam, but involves a seized/suspicious package, and the scammers will connect the victim to other scammers posing as Chinese government investigators.
Social security suspension scam
You will receive a call from someone claiming to work for the government regarding suspicious activity, fraud, or serious crimes connected to your social security number. You'll be asked to speak to an operator and the operator will explain the steps you need to follow in order to fix the problems. It's all a scam, and will lead to you losing money and could lead to identity theft if you give them private financial information.
Utilities cutoff
You get a call from someone who claims that they are from your utility company, and they claim that your utilities will be shut off unless you immediately pay. The scammer will usually ask for payment via gift cards, although they may ask for payment in other ways, such as Western Union or bitcoin.
Relative in custody Scammer claims to be the police, and they have your son/daughtenephew/estranged twin in custody. You need to post bail (for some reason in iTunes gift cards or MoneyGram) immediately or the consequences will never be the same.
Mexican family scam
This scam comes in many different flavours, but always involves someone in your family and Mexico. Sometimes the scammer will claim that your family member has been detained, sometimes the scammer will claim that your family member has been kidnapped, and sometimes the scammer will claim that your family member is injured and needs help.
General family scams
Scammers will gather a large amount of information about you and target your family members using different stories with the goal of gettimg them to send money.
One ring scam
Scammers will call you from an international number with the goal of getting you to return their call, causing you to incur expensive calling fees.

Online shopping scams

THE GOLDEN RULE OF ONLINE SHOPPING: If it sounds too good to be true, it probably is.
Dropshipping
An ad on reddit or social media sites like Facebook and Instagram offers items at huge discounts or even free (sometimes requiring you to reblog or like their page). They just ask you to pay shipping. The scam: The item will turn out to be very low quality and will take weeks or even months to arrive. Sometimes the item never arrives, and the store disappears or stops responding. The seller drop-ships the item from China. The item may only cost a few dollars, and the Chinese government actually pays for the shipping. You end up paying $10-$15 dollars for a $4 item, with the scammer keeping the profit. If you find one of these scams but really have your heart set on the item, you can find it on AliExpress or another Chinese retailer.
Influencer scams
A user will reach out to you on a social media platform, usually Instagram, and offer you the chance to partner with them and receive a free/discounted product, as long as you pay shipping. This is a different version of the dropshipping scam, and is just a marketing technique to get you to buy their products.
Triangulation fraud
Triangulation fraud occurs when you make a purchase on a site like Amazon or eBay for an item at a lower than market price, and receive an item that was clearly purchased new at full price. The scammer uses a stolen credit card to order your item, while the money from the listing is almost all profit for the scammer.
Instagram influencer scams
Someone will message you on Instagram asking you to promote their products, and offering you a discount code. The items are Chinese junk, and the offer is made to many people at a time.
Cheap Items
Many websites pop up and offer expensive products, including electronics, clothes, watches, sunglasses, and shoes at very low prices. The scam: Some sites are selling cheap knock-offs. Some will just take your money and run. What to do if you think you're involved with this scam: Contact your bank or credit card and dispute the charge. How to avoid: The sites often have every brand-name shoe or fashion item (Air Jordan, Yeezy, Gucci, etc) in stock and often at a discounted price. The site will claim to be an outlet for a major brand or even a specific line or item. The site will have images at the bottom claiming to be Secured by Norton or various official payment processors but not actual links. The site will have poor grammar and a mish-mash of categories. Recently, established websites will get hacked or their domain name jacked and turned into scam stores, meaning the domain name of the store will be completely unrelated to the items they're selling. If the deal sounds too good to be true it probably is. Nobody is offering brand new iPhones or Beats or Nintendo Switches for 75% off.
Cheap Amazon 3rd Party Items
You're on Amazon or maybe just Googling for an item and you see it for an unbelievable price from a third-party seller. You know Amazon has your back so you order it. The scam: One of three things usually happen: 1) The seller marks the items as shipped and sends a fake tracking number. Amazon releases the funds to the seller, and the seller disappears. Amazon ultimately refunds your money. 2) The seller immediately cancels the order and instructs you to re-order the item directly from their website, usually with the guarantee that the order is still protected by Amazon. The seller takes your money and runs. Amazon informs you that they do not offer protection on items sold outside of Amazon and cannot help you. 2) The seller immediately cancels the order and instructs you to instead send payment via an unused Amazon gift card by sending the code on the back via email. Once the seller uses the code, the money on the card is gone and cannot be refunded. How to avoid: These scammers can be identified by looking at their Amazon storefronts. They'll be brand new sellers offering a wide range of items at unbelievable prices. Usually their Amazon names will be gibberish, or a variation on FIRSTNAME.LASTNAME. Occasionally however, established storefronts will be hacked. If the deal is too good to be true its most likely a scam.
Scams on eBay
There are scams on eBay targeting both buyers and sellers. As a seller, you should look out for people who privately message you regarding the order, especially if they ask you to ship to a different address or ask to negotiate via text/email/a messaging service. As a buyer you should look out for new accounts selling in-demand items, established accounts selling in-demand items that they have no previous connection to (you can check their feedback history for a general idea of what they bought/sold in the past), and lookout for people who ask you to go off eBay and use another service to complete the transaction. In many cases you will receive a fake tracking number and your money will be help up for up to a month.
Scams on Amazon
There are scams on Amazon targeting both buyers and sellers. As a seller, you should look out for people who message you about a listing. As a buyer you should look out for listings that have an email address for you to contact the person to complete the transaction, and you should look out for cheap listings of in-demand items.
Scams on Reddit
Reddit accounts are frequently purchased and sold by fraudsters who wish to use the high karma count + the age of the account to scam people on buy/sell subreddits. You need to take precautions and be safe whenever you are making a transaction online.
Computer scams
Virus scam
A popup or other ad will say that you have a virus and you need to follow their advice in order to remove it. They are lying, and either want you to install malware or pay for their software.

Assorted scams

Chinese Brushing / direct shipping
If you have ever received an unsolicited small package from China, your address was used to brush. Vendors place fake orders for their own products and send out the orders so that they can increase their ratings.
Money flipping
Scammer claims to be a banking insider who can double/triple/bazoople any amount of money you send them, with no consequences of any kind. Obviously, the money disappears into their wallet the moment you send it.

Door to door scams

As a general rule, you should not engage with door to door salesmen. If you are interested in the product they are selling, check online first.
Selling Magazines
Someone or a group will come to your door and offer to sell a magazine subscription. Often the subscriptions are not for the duration or price you were told, and the magazines will often have tough or impossible cancellation policies.
Energy sales
Somebody will come to your door claiming to be from an energy company. They will ask to see your current energy bill so that they can see how much you pay. They will then offer you a discount if you sign up with them, and promise to handle everything with your old provider. Some of these scammers will "slam" you, by using your account number that they saw on your bill to switch you to their service without authorization, and some will scam you by charging higher prices than the ones you agreed on.
Security system scams
Scammers will come to your door and ask about your security system, and offer to sell you a new one. These scammers are either selling you overpriced low quality products, or are casing your home for a future burglary.
They ask to enter your home
While trying to sell you whatever, they suddenly need to use your bathroom, or they've been writing against the wall and ask to use your table instead. Or maybe they just moved into the neighborhood and want to see how you decorate for ideas.
They're scoping out you and your place. They want to see what valuables you have, how gullible you are, if you have a security system or dogs, etc.

Street scams

Begging With a Purpose
"I just need a few more dollars for the bus," at the bus station, or "I just need $5 to get some gas," at a gas station. There's also a variation where you will be presented with a reward: "I just need money for a cab to get uptown, but I'll give you sports tickets/money/a date/a priceless vase."
Three Card Monte, Also Known As The Shell Game
Unbeatable. The people you see winning are in on the scam.
Drop and Break
You bump into someone and they drop their phone/glasses/fancy bottle of wine/priceless vase and demand you pay them back. In reality, it's a $2 pair of reading glasses/bottle of three-buck-chuck/tasteful but affordable vase.
CD Sales
You're handed a free CD so you can check out the artist's music. They then ask for your name and immediately write it on the CD. Once they've signed your name, they ask you for money, saying they can't give it to someone else now. Often they use dry erase markers, or cheap CD sleeves. Never use any type of storage device given to you by a random person, as the device can contain malware.
White Van Speaker Scam
You're approached and offered speakers/leather jackets/other luxury goods at a discount. The scammer will have an excuse as to why the price is so low. After you buy them, you'll discover that they are worthless.
iPhone Street Sale
You're approached and shown an iPhone for sale, coming in the box, but it's open and you can see the phone. If you buy the phone, you'll get an iPhone box with no iPhone, just some stones or cheap metal in it to weigh it down.
Buddhist Monk Pendant
A monk in traditional garb approaches you, hands you a gold trinket, and asks for a donation. He holds either a notebook with names and amounts of donation (usually everyone else has donated $5+), or a leaflet with generic info. This is fairly common in NYC, and these guys get aggressive quickly.
Friendship Bracelet Scam More common in western Europe, you're approached by someone selling bracelets. They quickly wrap a loop of fabric around your finger and pull it tight, starting to quickly weave a bracelet. The only way to (easily) get it off your hand is to pay. Leftover sales
This scam involves many different items, but the idea is usually the same: you are approached by someone who claims to have a large amount of excess inventory and offers to sell it to you at a great price. The scammer actually has low quality items and will lie to you about the price/origin of the items.
Dent repair scams
Scammers will approach you in public about a dent in your car and offer to fix it for a low price. Often they will claim that they are mechanics. They will not fix the dent in your car, but they will apply large amounts of wax or other substances to hide the dent while they claim that the substance requires time to harden.
Gold ring/jewelry/valuable item scam
A scammer will "find" a gold ring or other valuable item and offers to sell it to you. The item is fake and you will never see the scammer again.
Distraction theft
One person will approach you and distract you, while their accomplice picks your pockets. The distraction can take many forms, but if you are a tourist and are approached in public, watch closely for people getting close to you.

Why UMI Will Not Fall Victim to Inflation: Dispelling Myths of “Deadly Issue”

Why UMI Will Not Fall Victim to Inflation: Dispelling Myths of “Deadly Issue”
https://preview.redd.it/lr1w0ukh2ik51.jpg?width=1024&format=pjpg&auto=webp&s=b413e6e6b2e94d2e9522571040151826b7874e77
With UMI staking, anyone anywhere in the world can generate new coins at the rate of up to 40 % a month, or up to 5,669 % a year, with no risk of falling victim to fraudsters. It means new opportunities for humanity which never existed before. However, many people who are used to miserable interests on bank deposits and financial pyramids that last a few months at most cannot understand what makes this possible. How can you safely earn up to 40 % a month with no risk of losing it all?
Sceptics cannot wrap their minds around this which makes them suspect there’s a catch to it. Therefore, it should come as no surprise that you can find various myths about UMI's “deadly issue” on forums and social networks. The most popular among them say that you simply cannot ensure long-term operation with this kind of “super-high income” and no one has any idea what will happen to this cryptocurrency in 10 or more years. Here's a forecast from sceptics, briefly: “deposits” with this percentage are simply impossible, it will inevitably cause hyperinflation, UMI cryptocurrency will devalue, and will share the fate of currencies in some of the less fortunate countries, such as Zimbabwe or Venezuela.
To counter these allegations, we've prepared a detailed article with arguments dispelling all these myths, nullifying all “forecasts” and putting the lid on this issue. Here we go!
What's the value behind the forecasts?
First of all, 10 or more years is too much of a long term, and forecasting so far in advance is simply impossible. Don't take us wrong here: it's not just about cryptocurrencies; it's about anything in the world. There was a time when people thought pagers, faxes, and landline phones had cheerful prospects, but look at what happened to them. They have been replaced by smartphones and the Internet accessible to all which no one believed was possible in the first place. New technologies emerge out of the blue and transform the world beyond recognition. The old — something everyone is used to — is replaced with something new and more
convenient. Something better.
10 years ago people believed in developing bank technologies, but then, all of a sudden, Bitcoin was created and transformed people's understanding of financial payments. It turned out anyone in the world can make payments with no intermediaries and generate new digital money. It's true that Bitcoin is not perfect, but millions use it all over the world. This number is also growing fast with each passing day.
Do you remember forecasts made for Bitcoin when it first appeared? Both ordinary people and respected world-class experts predicted it would soon die. No one believed it could last for even 10 years.

https://preview.redd.it/q1kzcxfw2ik51.png?width=800&format=png&auto=webp&s=17a12d73b9046a357cf6ecd77253472215c8bb24
Typical article predicting the end of Bitcoin from respected mass media. Source.

Here're some graphic examples from the leading world-class mass media:
“That's the End of Bitcoin.” Forbes, 2011, BTC price — $15.
“Bitcoin is headed to the ash heap.” USA Today, 2015, BTC price — $208.
“R.I.P., Bitcoin. It’s time to move on.” The Washington Post, 2016, BTC price — $382.
“Stay away from bitcoin and ethereum — they are complete garbage.” This is garbage." MarketWatch, 2017, BTC price — $2,345.
“Is Bitcoin Going To Zero?” Forbes, 2018, BTC price — $3,432.
In 2020, the BTC price is almost $12,000. The respected mass media have “declared Bitcoin dead” over 400 times (!!!) referring to its lack of backing, high issue rate, super-high price growth, and the like — just like the skeptics “declaring UMI dead” right now. However, despite all the discouraging forecasts, Bitcoin continues to successfully grow and rapidly gain in popularity.

https://preview.redd.it/6z60xwd13ik51.png?width=791&format=png&auto=webp&s=25a6799fe551c6e7f91aa016907e95ce032d7e5e
Over 12 years, Bitcoin has been declared dead 381 times, but it only grows stronger with each passing year. Source.

All of the above is proof that you shouldn't put blind trust in various forecasts, even coming from respected sources. Forecasts are mere opinions and arguments, but no one can know for
sure what will happen in 10, 100, or 1,000 years. No expert can know that. Similarly, no one knows what will happen to UMI many years from now.
UMI can solve any issues on the fly
We cannot know the future, but we did all we could to make our coin last forever. Most existing cryptocurrencies have a very important problem — they cannot support high-quality growth and rapidly become obsolete.
To explain this, we'd like to quote our Whitepaper:
"Despite the apparition of new technology solutions, the Bitcoin blockchain still holds only about 2,000 transactions, and it takes about 10 minutes to create a block. In 11 years, developers still did not manage to come to an agreement and implement a solution that would allow scaling the system and upgrade performance.
Most other cryptocurrencies face a similar problem. They are launched and keep operating in an almost initial state even after numerous innovative solutions become available. For example, the Ethereum network has been attempting to switch to the PoS algorithm for over two years now, but due to code complexity, security threats, and issues of reaching consensus, this causes great inconvenience."
https://preview.redd.it/ezxzrpx43ik51.png?width=800&format=png&auto=webp&s=207f8a27a59fac760fc541dae6abd30d148296f5
Screenshot of a page in the UMI Whitepaper. Have you read it? It answers a lot of questions. Link.

Bitcoin itself is technically obsolete. This is besides the fact that it has a load of other problems. For instance, BTC is supposed to completely stop coin mining in 2140, meaning miners will lose motivation to support the network. What happens then? The hope is that the main source of income for miners will be transfer fees, but will they want to maintain powerful equipment for a reward in the form of small fees? If fees are big, will people want to pay those? Will they find a different solution? Will users just leave the Bitcoin ecosystem and join more high-tech cryptocurrencies like UMI?
When we designed UMI, we accounted for all these issues and launched a promising project with a conveniently scalable ecosystem. Even if UMI faces some challenges in the future, we will make amendments as the network grows. We will act as appropriate judging from the project's current status. They will be based on the situation and the current state of the project.
It's true that upgrade decisions have been and are being made by all leading crypto projects, including Bitcoin and Ethereum, but UMI supports really safe and rapid innovation. The network can be easily modified and scaled with cutting edge technology solutions. While other cryptocurrencies simply become obsolete, we can handle all kinds of challenges on the fly. The UMI network will grow and improve to be always up to date, keep up with the times, and prevent problems in 10, 100, or 1,000 years.
At this point, the UMI network is in excellent shape, and the smart contract offers you relevant and actionable staking opportunities. We've thought out every detail, and the brisk growth of our community proves it best of all.
There is no "deadly inflation"
And, lastly, let's bring an issue with supposedly too-high emission to a close. UMI is typically accused of paying a too high reward for staking — as much as 40% a month, or 5,669% a year — which no one and nothing else in this world can pay. Eventually, it might end up with inflation as it happened in Zimbabwe and Venezuela, etc.,
Let us look at real facts. Those who consider a 40% monthly growth impossible should look at bitcoin again as the most outstanding example which has proven that nothing is impossible. Imagine how many times your deposit would have grown if 10 years ago you had bought bitcoins or inexpensive mining equipment producing a reward of 50 BTC several times a day.
Please consider the following:
In March 2010, BitcoinMarket.com started operating as the first bitcoin exchange, and 1 BTC cost a lot less than a cent — $0.003.
At the time of writing this article, the price for 1BTC was about $12,000.
It means those who bought bitcoins 10 years ago have increased their "deposit" by nearly 400,000,000% (!!!). Four hundred million percent in ten years! This is a real fact.
Those who bought bitcoins when the price was a few cents or dollars also achieved the perfect result by increasing their "deposit" by thousand or million times.
Well, now the percentage in UMI staking doesn't seem so crazy, does it? The only difference
is that BTC "deposit" grows in line with the BTC price while UMI deposit growth is ensured the growth of the number of UMI coins, which in turn doesn't prevent the price from surging. In fact, both cases demonstrate a multiple growth of the "deposit".
All of the above is proof that the reason for inflation in Zimbabwe, Venezuela, etc is a bad economy, not a high emission. In late March. roughly speaking, in one day, the FED (U.S. Federal Reserve System) released 2.2 trillion dollars to support the economy during the coronavirus pandemic. Similar financial injections are regular in the USA, the country which is the most advanced world's economy.
These facts indicate that UMI has no "deadly issue" at all and, unlike the USA, it doesn't "print" anything.
Here is bare statistics form the UMI blockchain:
The UMI cryptocurrency was launched on June 1. Since the launch, it's been 3 months.
18,000,000 UMI coins were initially issued.
In total, there are now about 18,800,000 UMI coins.
In other words, in three months, the total number of UMI coins increased by only 4.4%. Does it look like "deadly inflation"?

https://preview.redd.it/gsdjbwp83ik51.png?width=800&format=png&auto=webp&s=8d4591a24b3ddc63f8501f1b7fe7a4c02b7da89c
In 3 months, the number of UMI coins has shown a few percent increase. Source.

Let's move on:
We'd like to reiterate that the total number of UMI coins is almost 18,800,000.
There are about 14,500,000 coins on the genesis address today.
Almost 4,000,000 coins are involved in staking.
Thus, only 300,000 UMI (!)are freely circulated on the market. The remaining 18,500,000 coins are either used in staking or have not yet been released to the market.
https://preview.redd.it/f7b28jid3ik51.png?width=800&format=png&auto=webp&s=5ff8338121ebfe398cfb498a0cfcc00446ea6225
The number of coins stored on the genesis address at the time of writing the article. Source.

In real fact, UMI has no super-high emission. This fact has been proven. For a three-month period, which is a quarter of a year, the number of UMI has hardly changed and equals about 1.5% of the total number of coins on the market.
The truth is that UMI economy depends on a lot of factors. For example, burning 50,000 coins to create a structure. However, from a more general point of view, the UMI economic model itself is designed to encourage people to "save" rather than sell UMI coins. This is a crucial point that allows us to make progress, even with a high emission.
Moreover, it will take a billion-dollar staking structure that will be able to provide the highest possible emission on the UMI network a lot of years to appear. While it doesn't happen, all these forecasts can be regarded as irrelevant for today. Keep in mind that a 40% monthly profit will be available to the most successful structures and only after many years of development. To have your coins increased by 40% per month, your structure must have over 50 (!) times more coins than the number of coins initially generated by the network. And since this structure will do everything possible for the benefit of the UMI cryptocurrency, even 40% per month will not pose a risk to UMI's sustainable development.
Conclusions are as follows:
UMI offers no kind of "killing sky-high returns". Please don't take this myth seriously. UMI is growing. The current smart contract offers reasonable and up-to-date opportunities for UMI staking and poses no problem. If, however, a problem arises — we have all the tools to find an immediate solution. All these negative forecasts are not worth a brass farthing. They always have been and always will be. At all times and in all places. But they are highly unlikely to come true. Bitcoin outsmarted the most reputable and shrewd financial analysts. Why don't UMI, which is a lot more advanced than bitcoin, try to do the same?
UMI is a decentralized, strong, and high-tech network. It can exist the way it is now forever. But as it grows, it will improve to be always up to date, keep up with the times and prevent any problems. We are contributing to a great thing — we're creating a free economic system that will profitable for the entire human family. This is an opportunity to overcome social inequality and make regular people financially independent. So let's make every effort to make things go well. Ignore all evil-wishers and their predictions. Just join other users and go towards your dream. Then we will certainly succeed in it all.
Sincerely yours, UMI team
