New England

NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Ravencoin Open Developer Meeting - 1/4/2019

[14:04] Hi everyone! [14:04] :dabbitwave: [14:04] Hey Everybody! [14:04] Hello 😃 [14:04] Sorry we're getting started a bit late. [14:04] Topics: SLC Meetup (March 15th) [14:04] 👋 [14:04] Roadmap breakdown - posted to github [14:05] IPFS (integration) [14:05] greetings 👋 [14:05] So, SLC Meetup on the 15th! [14:05] Great! [14:05] Hi! [14:06] Hi all — a special thanks to the developers and congratulations on an amazing first year!!! # [14:06] <[Dev] Blondfrogs> Hello Everyone! [14:07] We have a tentative agenda with @Tron , @corby speaking. [14:08] We would like to have nice walkthrough of the Raven DevKit for the meetup. [14:08] We are planning on hosting a meetup in SLC at the Overstock building on March 15th from 6:00pm-9:00pm. It is free admission, but there is a page on meetup.com where people can rsvp so that we have a somewhat accurate headcount for food. [14:08] sup guys [14:08] hey russ [14:09] We are planning on having a few speakers and have allotted a bit of time at the end for people to meet and greet each other. [14:09] can you guys link us to the page somewhere when thats available? 😄 [14:10] free food?! [14:10] todays topic? [14:10] yeah can we indicate pepperoni pizza [14:10] Sounds good to me @Jeroz Nothing ordered yet though. 😃 [14:10] only pepperoni pizza is served at true blockchain meetings right [14:10] :blobhide: [14:10] Absolutely. The itinerary just needs to be finalized and then I'll make a broad post about the rest of the details. [14:11] https://www.meetup.com/Salt-Lake-City-salt-lake-city-Meetup/ [14:11] 😭 so far away [14:11] West Coast! [14:11] @MTarget But there's pizza, so worth the travel time. [14:11] lol [14:12] I'll be watching the stream if its available since i'm from montreal/canada 😛 [14:12] Ah yes, I love $300 pizza 😉 [14:12] as long as I get to see your smiling faces @Tron @RavencoinDev then it's worth the time [14:12] We'll be there. [14:12] We'll be messaging additional details as they get finalized. [14:12] Greeting and salutations! [14:12] sup [14:13] Hey, $300 is considerably cheaper than 2 $3,700,000 pizzas. [14:14] Ok, switching topics... [14:14] yeah its a way to fly, [14:14] question is whether those piza's will be paid for in RVN coin or not :ThinkBlack: [14:14] Roadmap [14:14] It hasn't changed, just added some detail. [14:14] https://github.com/RavenProject/Ravencoin/tree/masteroadmap [14:15] nice [14:15] This now links to a breakdown for messaging, voting, anti-spam, and rewards (dividends) [14:15] will there be any additional RPC functionality coming in the future, thinking in terms of some functions that are only available in ravencore-lib [14:15] apologies if now is not time to ask questions, i can wait for later [14:15] "Phase 7 - Compatibility Mode" - that's new 😮 [14:15] The protocol for messaging is pretty well established, but the rest isn't in stone (code) yet. [14:16] can you give us details on compatibility mode? [14:16] In broad brush strokes. [14:17] The idea is to allow ravend to act as a daemon that looks like a single coin. [14:17] so ravend that only works with the bitcoin asset? [14:18] interesting [14:19] So you start it with an option to only work with a single asset/token account or something? [14:19] hmm compelling what is the reason for this? some kind of scale or performance? [14:19] ^ [14:19] Example: Configure ravend to listen for transfer RPC call for senttoaddress or sendfrom, but for a specific asset. This would allow easy integration into existing system for assets. [14:20] Only the daemon or the whole wallet UI? [14:20] yeah thats great, rpc functions dont allow us to do this yet, if i recall [14:20] or at least we depend more on ravencore lib [14:20] so like asset zmq [14:20] that's smart [14:20] @Tron it also sounds like it makes our life easier working with RPC, instead of core all the time for some functionality [14:21] if i understand correctly anyways [14:21] So you could run numerous instances of ravend each on their own network and RPC port, each configured for a different asset. You would need some balance of RVN in each one to cover transaction fees, then. [14:21] id be curious to know what all the advantages are of this [14:21] one more question, how would i decentralize the gateway between bitcoin mainnet/ravencoin mainnet? in the current RSK implementation they use a federated gateway, how would we avoid this? [14:21] it sounds neato [14:21] Just the daemon. The alternative is to get exchanges to adapt to our RPC calls for assets. It is easier if it just looks like Bitcoin, Litecoin or RVN to them, but it is really transferring FREE_HUGS [14:22] That makes sense. Should further increased exchange adoption for each asset. [14:22] hmm yeah its just easier for wallet integration because its basically the same as rvn and bitcoin but for a specific asset [14:22] so this is in specific mind of exchange listings for assets i guess [14:23] if i understand rightly [14:23] @traysi Gut feel is to allow ravend to handle a few different assets on different threads. [14:23] Are you going to call it kawmeleon mode? [14:23] Lol [14:23] I read that as kaw-melon mode. [14:24] same lol [14:24] so in one single swoop it possible to create a specific wallet and server daemon for specific assets. great. this makes it easier for exchanges, and has some added advantages with processing data too right? [14:24] Still keeping a RVN balance in the wallet, as well, Tron. How will that work is sendtoaddress sends the token instead of the RVN? A receive-RVN/send tokens-only wallet? [14:25] @traysi Yes [14:25] sendtoaddress on the other port (non RVN port) would send the asset. [14:25] This will be a hugely useful feature. [14:25] ^ [14:26] @Tron currently rpc function not support getaddresses senttowallet and this has to be done in ravencore lib, will this change you propose improve this situation [14:26] Config might look like {"port":2222, "asset":"FREE_HUGS", "rpcuser":"hugger", "rpcpass":"gi3afja33"} [14:26] how will this work cross-chain? [14:28] @push We'd have to go through the rpc calls and work out which ones are supported in compatibility mode. Obviously the mining ones don't apply. And some are generic like getinfo. [14:28] ok cool 👍 cheers [14:29] for now we continue using ravencore lib for our plans to keep track i just wondering if better way [14:29] as we had some issue after realising no rpc function for getting addresses of people who had sent rvn [14:29] @push | ravenland.org all of the node explorer and ravencore-lib functionality is based on RPC (including the addressindex-related calls). Nothing you can't do with RPC, although I'm not sure of the use cases you're referring to.. [14:29] interesting, so ravencore lib is using getrawtransaction somehow [14:29] i thought this may be the case [14:29] that is very useful thankyou for sharing this [14:30] look into addressindex flag and related RPC calls for functions that operate on addresses outside your wallet [14:30] thank you that is very useful, tbh i am not very skilled programmer so just decoding the hex at the raven-cli commandline was a challenge, i shall look more into this, valued information thanks as this was a big ? for us [14:31] Ok, things have gone quiet. New topic. [14:31] IPFS (integration) [14:31] GO [14:33] ... [14:33] <[Dev] Blondfrogs> So, we have been adding ipfs integration into the wallet for messaging. This will allow the wallets to do some pretty sweet stuff. For instance, you will be able to create your ipfs data file for issuing an asset. Push it to ipfs from the wallet, and add the hash right into the issuance data. This is going to allow for a much more seamless flow into the app. [14:34] <[Dev] Blondfrogs> This ofcourse, will also allow for users to create messages, and post them on ipfs and be able to easily and quickly format and send messages out on the network with ipfs data. [14:34] It will also allow optional meta-data with each transaction that goes in IPFS. [14:34] will i be able to view ipfs images natively in the wallet? [14:34] <[Dev] Blondfrogs> Images no [14:34] We discussed the option to disable all IPFS integration also. [14:35] @russ (kb: russkidooski) Probably not. There's some risk to being an image viewer for ANY data. [14:35] No option in wallet to opt into image viewing? [14:35] cool so drag and drop ipfs , if someone wanted to attach an object like an image or a file they could drag drop into ui and it create hash and attach string to transaction command parameters automatically [14:35] We could probably provide a link -- with a warning. [14:35] nomore going to globalupload.io [14:35] :ThinkBlack: [14:35] I understand that the wallet will rely on globalupload.io. (phase 1). Is it not dangerous to rely on an external network? Or am I missing something? [14:36] hmm [14:36] interesting, i suppose you could hash at two different endpoints and compare them [14:36] if you were that worried [14:36] and only submit one to the chain [14:36] You will be able to configure a URL that will be used as an IPFS browser. [14:36] Oh ic [14:36] you wont flood ipfs because only one hash per unique file [14:36] <[Dev] Blondfrogs> There are multiple options for ipfs integration. We are building it so you can run your own ipfs node locally. [14:36] <[Dev] Blondfrogs> or, point it to whatever service you would like. e.g. cloudflare [14:36] this is very cool developments, great to see this [14:37] Just like the external block explorer link currently in preferences. [14:37] @[Dev] Blondfrogs what about a native ipfs swarm for ravencoin only? [14:37] We have discussed that as an option. [14:37] @push | ravenland.org Considering having a fallback of upload through globalupload.io and download through cloudflare. [14:37] <[Dev] Blondfrogs> @russ (kb: russkidooski) We talked about that, but no decisions have been made yet. [14:37] yeah, i would just use two endpoints and strcompare the hash [14:37] as long as they agree good [14:37] submit tran [14:38] else 'potentially mysterious activity' [14:38] ? [14:38] if you submitted the file to ipfs api endpoints [14:38] Will the metadata just be a form with text only fields? [14:39] and then you would get 2 hashes, from 2 independent services [14:39] that way you would not be relying on a central hash service [14:39] and have some means of checking if a returned hash value was intercepted or transformed [14:39] i was answering jeroz' question [14:40] about relying on a single api endpoint for upload ipfs object [14:40] We have also kicked around the idea of hosting our own JSON only IPFS upload/browse service. [14:41] I have a service like this that is simple using php [14:41] we only use it for images right now [14:41] but fairly easy to do [14:41] Yup [14:42] Further questions about IPFS? [14:43] contract handling? file attach handling? or just text fields to generate json? [14:44] trying to get an idea of what the wallet will offer for attaching data [14:44] Probably just text fields that meet the meta-data spec. [14:44] ok noted [14:44] What do you mean by contract handling @sull [14:45] We won't prevent other hashes from being added. [14:45] asset contract (pdf etc) hash etc [14:45] <[Dev] Blondfrogs> also, being able to load from a file [14:45] got it, thanks [14:47] Let's do some general Q&A [14:48] Maybe just a heads up or something to look for in the future but as of right now, it takes roughly 12 hours to sync up the Qt-wallet from scratch. Did a clean installation on my linux PC last night. [14:48] Any plans or discussions related to lack of privacy of asset transfers and the ability to front run when sending to an exchange? [14:48] ^ [14:48] Is there a way to apply to help moderate for example the Telegram / Discord, i spend alot of time on both places, sometimes i pm mods if needed. [14:49] Any developed plans for Asset TX fee adjustment? [14:49] also this^ [14:49] @mxL86 We just created a card on the public board to look into that. [14:49] General remark: https://raven.wiki/wiki/Development#Phase_7_-_Compatible_Mode = updated reflecting Tron's explanation. [14:49] @mxL86 That's a great question. We need to do some profiling and speed it up. I do know that the fix we added from Bitcoin (that saved our bacon) slowed things down. [14:50] Adding to @mxL86 the sync times substantially increased coinciding with the asset layer activation. Please run some internal benchmarks and see where the daemon is wasting all its cycles on each block. We should be able to handle dozens per second but it takes a couple seconds per block. [14:50] @BW__ no plans currently for zk proofs or anything if that's what you're asking [14:50] You are doing a great job. Is there a plan that all this things (IPFS) could be some day implemented in mobile wallet? Or just in QT? [14:50] i notice also that asset transactions had some effect on sync time as we were making a few. Some spikes i not analysed the io and cpu activity properly but will if there is interest [14:51] we are testing some stuff so run into things i am happy to share [14:51] @BW__ Might look at Grin and Beam to see if we can integrate Mimble Wimble -- down the road. [14:51] yeees [14:51] @J. | ravenland.org work with the telegram mods. Not something the developers handle. [14:51] i love you [14:51] @J. | ravenland.org That would be best brought up with the operators/mods of teh telegram channel. [14:51] @corby @Tron thnx [14:51] @S1LVA | GetRavencoin.org we're planning on bumping fees to... something higher! [14:51] no catastrophic failures, just some transaction too smals, and mempool issues so far, still learning [14:52] @corby i thought that this may happen :ThinkBlack: [14:52] @corby x10? 100x? 1000x? Ballpark? [14:52] Definitely ballpark. [14:52] 😃 [14:52] 😂 [14:52] Is a ballpark like a googolplex? [14:53] @push | ravenland.org asset transactions are definitely more expensive to sync [14:53] yes yes they are [14:53] they are also more expensive to make i believe [14:53] 10,000x! [14:53] as some sync process seems to occur before they are done [14:53] @traysi ★★★★★ thanks for the suggestions we are going to be looking at optimizations [14:53] But, it is way slower than we like. Going to look into it. [14:53] i do not understand fully its operation [14:53] 1000x at minimum in my opinion [14:53] its too easy to spam the network [14:54] yes there has been some reports of ahem spam lately [14:54] :blobhide: [14:54] 😉 [14:54] cough cough ravenland [14:54] @russ (kb: russkidooski) we're in agreement -- it's too low [14:54] default fee 0.001 [14:54] ^ something around here [14:54] @corby yep we all are i think [14:55] waaay too low [14:55] meaningful transactions start with meaningful capital expense [14:55] though there is another scenario , there are some larger volume, more objective rich use cases of the chain that would suffer considerably from that [14:55] just worth mentioning, as i have beeen thinking about this a lot [14:55] there are some way around, like i could add 1000 ipfs hashes to a single unique entity, i tested this and it does work [14:56] @russ (kb: russkidooski) What would you suggest. [14:57] I had a PR for fee increase and push back. [14:57] Ignore the push back. 0.001 RVN is not even a micro-farthing in fiat terms [14:57] definitely around 1000x [14:57] Vocal minority for sure [14:57] ^ yep [14:57] @russ (kb: russkidooski) That sounds reasonable. [14:57] Couple hundred Fentons [14:58] right now an asset transaction is 0.01 of a penny essentially [14:58] 1 RVN would work now, but not when RVN is over $1. [14:58] yes exactly [14:58] Hi. Late to the party. [14:58] We are also talking about a min fee. The system will auto-adapt if blocks fill up. [14:58] im thinking tron, some heavy transaction use cases would fall out of utility use if that happened [14:58] so whats the thinking there [14:59] is there a way around the problem, bulked ipfs hash transactions? [14:59] 1000x would put us around btc levels [14:59] maybe a minimum 500x? [14:59] @russ (kb: russkidooski) Agreed. [14:59] <[Dev] Blondfrogs> It is time to wrap it up here. Everyone. Thank you all for your questions and thoughts. We will be back in 2 weeks. 😃 [14:59] Small increase and review. [14:59] Thanks all! [14:59] Cheers. [15:00] yeah sorry for 1 million questions guys hope i didnt take up too much time [15:00] cheers all 👍 [15:00] Thanks everyone [15:00] Thanks everyone for participating!!! [15:00] That is what we are here for [15:00] 100x-500x increase, 1000x maximum [15:00] 🍺

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

Integrated into Blockchain Financial

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html).

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Groestlcoin Sentinel (Android & Blackberry) – Mainnet + Testnet

What is Sentinel?

Groestlcoin Sentinel is the easiest and fastest way to track/receive/watch payments in your offline Groestlcoin Wallets. Groestlcoin Sentinel is compatible with any standard Groestlcoin address, BIP44 XPUB (Extended Public Key) BIP49 YPUB and BIP84 ZPUB
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that particular wallet.

Transcript from Ravencoin Open Developer Meeting - Nov. 16, 2018

Tron at 2:03 PM

Topics: Messaging (next phase) UI 2.2 - Build from develop - still working out a few kinks Mobile - Send/Rcv/View Assets - In progress Raven Dev Kit -Status

RavencoinDev at 2:04 PM

Hey Everybody! Let's get started!Thanks Tron for posting the topics.Tron is going talk about Messaging Plans.Let's start there.

Chatturga at 2:06 PM

It looks like this channel is not connected to the IRC. One moment

RavencoinDev at 2:07 PM

Well, we going to move forward as the tech guys fix the IRC connections.

Tron at 2:07 PM

I wanted to have a doc describing the messaging, but it isn't quite ready.I understand this isn't going to IRC yet, but I'm starting anyway.

RavencoinDev at 2:08 PM

Look for it soon on a Medium near you.

Tron at 2:08 PM

Summary version: Every transaction can have an IPFS hash attached.

Vincent at 2:09 PM

any plans for a 'create IPFS' button?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

on asset creatin window also?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

sweet

Tron at 2:09 PM

IPFS attachments for transactions that send ownership token or channel token back to the same address will be considered broadcast messages for that token.The client will show the message.Some anti-spam measures will be introduced.If a token is in a new address, then messages will be on by default.The second token in an address, the channel will be available, but muted by default.

RavencoinDev at 2:11 PM

That way I can't spam out 21b tokens and then start sending messages to everybody.

Tron at 2:11 PM

We'd like to have messaging in a reference client on all six platforms.

corby at 2:11 PM

Hi!

Tron at 2:11 PM

Photos will not be shown. Messages will be "linkified"

RavencoinDev at 2:12 PM

and plain text.We'll start with the QT wallet support

Tron at 2:12 PM

Any other client is free to show any IPFS message they choose.The messaging is fully transparent.

Rikki RATTOE at 2:13 PM

ok, so messaging isn't private

Tron at 2:13 PM

Anyone could read the chain and see the messages.

RavencoinDev at 2:13 PM

No, never was planned to be private

MSFTserver-mine more @ MinerMore at 2:13 PM

irc link should be fixed

Tron at 2:13 PM

It is possible to put encrypted content in the IPFS, but then you'd have to distribute the key somehow.

RavencoinDev at 2:13 PM

Thanks MSFT!

Chatturga at 2:13 PM

Negative

Tron at 2:14 PM

Core protocol changes Extend the OP_RVN_ASSET to include for any transfer: RVNT <0xHH><0x12><0x20><32 bytes encoding 256 bit IPFS hash> 0xHH - File type 0x00 - NO data, 0x01 - IPFS hash, 0x02 through 0xFF RESERVED 0x12 - IPFS Spec - Using SHA256 hash 0x20 - IPFS Spec - 0x20 in hex specifying a 32 byte hash. …. (32 byte hash in binary)

corby at 2:14 PM

By it's nature nothing on chain is private per se. Just like with wallets you'd need to use crypto to secure messaging between parties.

Tron at 2:14 PM

Advantages: This messaging protocol has the advantage of not filling up the blockchain. The message information is public so IPFS works as a great distributed store. If the messages are important enough, then the message sender can run nodes that "PIN" the message to keep a more durable version. The message system cannot be spoofed because any change in the message will result in a different hash, and therefore the message location will be different. Only the unique token holder can sign the transaction that adds the message. This prevents spam. Message clients (wallets), can opt-in or opt-out of messages by channel. Meta-message websites can allow viewing of all messages, or all messages for a token. A simple single channel system is supported by the protocol, but a channel could be sub-divided by a client to have as many sub-channels as desired. There are no limits on the number of channels per token, but each channel requires the 5 RVN fee to create the channel.

RavencoinDev at 2:14 PM

So, somebody could create their own client and encrypt the data on the blockchain if they wished.

corby at 2:15 PM

Wow Tron types fast

Rikki RATTOE at 2:15 PM

yeah there was some confusion in the community whether messaging would be private and off chain

Tron at 2:15 PM

Anti-Spam Strategy One difficulty we have is that tokens can be sent to any Ravencoin asset holder unsolicited. This happens on other asset platforms like Counterparty. In many cases, this is good, and is a way for asset issuers to get their token known. It is essentially an airdrop. However, combined with the messaging capabilities of Ravencoin, this can, and likely will become a spam strategy. Someone who wants to send messages (probably scams) to Ravencoin asset holders, which they know are crypto-savvy people, will create a token with billions of units, send it to every address, and then message with the talking stick for that token. Unless we preemptively address this problem, Ravencoin messaging will become a useless spam channel. Anyone can stop the messages for an asset by burning the asset, or by turning off the channel. A simple solution is to automatically mute the channel (by default) for the 2nd asset sent to an address. The reason this works is because the assets that you acquire through your actions will be to a newly generated address. The normal workflow would be to purchase an asset on an exchange, or through a ICO/STO sale. For an exchange, you'll provide a withdrawal address, and best practice says you request a new address from the client with File->'Receiving addresses…'->New. To provide an address to the ICO/STO issuer, you would do the same. It is only the case where someone is sending assets unsolicited to you where an address would be re-used for asset tokens. This is not 100% the case, and there may be rare edge-cases, but would allow us to set the channels to listen or silent by default. Assets sent to addresses that were already 'on-chain' can be quarantined. The user can burn them or take them out of quarantine.

RavencoinDev at 2:18 PM

Okay, let me know when/if you guys read through all that. 📷📷2

corby at 2:18 PM

To be clear this is a client-side issue -- anyone will be able to send anything (including messages) to any address on chain..

RavencoinDev at 2:18 PM

It'll be in the Medium post later.

Tron at 2:19 PM

@corby The reference client will only show messages signed by the issuer or designated channels.Who is ready for another wall of text? 📷

corby at 2:19 PM

I hear that's the plan 📷 just pointing out that it is on the client in these cases..

Tron at 2:20 PM

Yes, any client can show anything gleaned from the chain.Goal: A simple message format without photos. URL links are allowed and most clients will automatically "linkify" the message for valid URLs. For display, message file must be a valid json file. { "subject":"This is the optional subject", "message": "This is required.", "expires": 1578034800 } Only "message" is required {"message":"Hello world"}

bhorn at 2:21 PM

expires?

Vincent at 2:21 PM

discount coupon?

Tron at 2:21 PM

If you have a message that worthless (say after a vote), just don't show the message.

bhorn at 2:21 PM

i see - more client side operation

corby at 2:21 PM

/expires

Tron at 2:22 PM

Yep. And the expiration could be used by IPFS pinners to stop worrying about the message. Optional

RavencoinDev at 2:22 PM

If the client sees a message that is expired it just won't display it.

Vincent at 2:23 PM

will that me messaged otherwise may cause confusion?"expired'

RavencoinDev at 2:23 PM

YesWe'll do our best to make it intuitive.

Tron at 2:24 PM

Client handling of messages Pop-up messages or notifications when running live. Show messages for any assets sent to a new address - by default Mute messages for assets sent to an address that was already on-network. Have a setting to not show messages older than X IPFSHash (or 8 bytes of it) =

Rikki RATTOE at 2:25 PM

will there be a file size limit for IPFS creation in the wallet?

RavencoinDev at 2:25 PM

We'll also provide updated documentation.

Tron at 2:26 PM

Excellent question Rikki. Here are some guidelinesGuidelines: Clients are free to show or not show poorly formed messages. Reference clients will limit message display to properly formed messages. If subject is missing, the first line of the message will be used (up to 80 chars). Standard JSON encoding for newlines, tabs, etc. https://www.freeformatter.com/json-escape.html Expiration is optional, but desired. Will stop showing the message after X date, where X is specified as Unix Epoch. Good for invites, voting requests, and other time sensitive messages that have no value after a specific date. By default clients will not show a message after X blocks (default 1 year) Amount of subject shown will be client dependent - Reference client may cut off at 80 chars. Messages longer than 15,000 (about 8 pages) will not be pinned to IPFS by some scanners. Messages longer than 15,000 characters may be rejected altogether by the client. Images will not be shown in reference clients. Other clients may show any IPFS content at their discretion. IPFSHash is only a "published" message if the Admin/Owner or Channel token is sent from/to the same address. This allows for standard transfers with metadata that don't "publish".Free Online JSON Escape / Unescape Tool - FreeFormatter.comA free online tool to escape or unescape JSON strings

RavencoinDev at 2:26 PM

We're hoping to add preferences that will allow the user to customize their messaging experience.

Tron at 2:27 PM

Also, happy to receive feedback from everyone.

corby at 2:27 PM

In theory though if you maintain your own IPFS nodes you should be able to reference files of whatever size right?

Steelers at 2:27 PM

How about a simple Stop light approach - Green (ball) New Message, Yellow (Ball) Expiring Messages, Red (Ball) Expired Messages

RavencoinDev at 2:27 PM

Yes please! That's the point of sharing it here

Sure, that's coming.

oki 📷 cheers

RavencoinDev at 2:29 PM

Questions on messaging?

Jeroz at 2:30 PM

Not sure if I missed it, but how fast could you send multiple messages in succession?

BruceFenton at 2:30 PM

Some kind of sweep feature or block feature for both tokens and messages could be useful Certain messages will be illegal to possess in certain jurisdictions If someone sends a picture of Tiennneman tank man in China or a message calling for the overthrow of a ruler it could be illegal for someone to have There’s no way for that jurisdiction to censor the chain So some users might want the option to purge messages or not receive them client side / on the wallet

Tron at 2:30 PM

Messages are a transaction.

RavencoinDev at 2:30 PM

So it'll cost you to spam messages.They can only send a hash to that picture and the client won't display anything not JSON

corby at 2:31 PM

purge/block is the age old email spam

Tron at 2:31 PM

The Reference client - other clients / web sites, etc can show anything they wish.

RavencoinDev at 2:31 PM

You can also burn a token if you never want to receive messages from that token owner.

UserJonPizza|MinePool.com|Mom at 2:32 PM

Can't they just resend the token?

Tron at 2:33 PM

Yes, but it would default to mute.📷2

RavencoinDev at 2:33 PM

meaning it would show up in a spam foldetab

bhorn at 2:33 PM

is muting available for the initial asset as well?

RavencoinDev at 2:33 PM

Something easy to ignore if muted.

Tron at 2:33 PM

@bhorn Yes

BruceFenton at 2:33 PM

Can users nite some assets and not others?

Tron at 2:33 PM

@bhorn It just isn't the default.

BruceFenton at 2:33 PM

Mute

RavencoinDev at 2:33 PM

YesYou can mute per token.

BruceFenton at 2:34 PM

Great

Tron at 2:34 PM

And per token per channel.

Jeroz at 2:34 PM

channels are the subtokens?

BruceFenton at 2:34 PM

What’s per token per channel mean ?

Tron at 2:34 PM

The issuer sends to the "Primary" channel.Token owner can create channels like "Alert", "Emergency", etc.These "talking sticks" are similar to unique assets.📷1ASSET~Channel

RavencoinDev at 2:37 PM

Okay, we have a few more topics to cover today.Tron will post more details on Medium and we can continue discussions there.

Jeroz at 2:38 PM

Ah, I missed channel creation bit for each token with the 5 RVN / channel cost. It makes more sense to me now.

RavencoinDev at 2:38 PM

The developers are working towards posting a new version 2.2 that has the updated UI shown on twitter.

Vincent at 2:39 PM

twit link?

RavencoinDev at 2:39 PM

The consuming of large birds (not ravens) might slow the release a bit.So likely the week after Thanksgiving.

[Dev] Blondfrogs at 2:39 PM

The new UI will contain: - New menu layout - New icons - Dark mode - Added RVN colors

Dan1666 at 2:39 PM

+1 Dark mode

RavencoinDev at 2:39 PM

DARK MODE!

Dan1666 at 2:40 PM

so pleased about that

RavencoinDev at 2:40 PM

I can honestly say it'll be the nicest crypto wallet out there.

[Dev] Blondfrogs at 2:40 PM

A little sneak peak, but this is not the final project📷📷6📷3

!S1LVA | MINEPOOL at 2:40 PM

Outstanding

Dan1666 at 2:41 PM

reminds me of Sub7 ui for those that might remember

UserJonPizza|MinePool.com|Mom at 2:41 PM

Can we have an asset count at the top?

[Dev] Blondfrogs at 2:41 PM

Icons will be changing

Vincent at 2:41 PM

does the 'transfer assets' have a this for that component?

Tron at 2:41 PM

Build from develop to see the sneak preview in action.There may be small glitches depending on OS. These are being worked on.

Rikki RATTOE at 2:41 PM

No plans for the mobile wallet to show an IPFS image I'm assuming? Would be a nice feature if say a retail store could send a QR coupon code to their token holders and they could scan the coupon using their wallet in store

[Dev] Blondfrogs at 2:42 PM

@Vincent That will probably be a different section added later📷1

RavencoinDev at 2:42 PM

Yes, Rikki we do want to support messaging.Looking into how that would work with Apple and Google push.

push | ravenland.org at 2:42 PM

sub7📷1hahaoldschoolit so is similar aswell

[Master] Roshii at 2:43 PM

Messages are transactions no need for any push

Tron at 2:43 PM

@Rikki RATTOE There's a danger in showing graphics where anyone can post anything without accountability for their actions. A client that only shows tokens for a specific asset could do this📷1

RavencoinDev at 2:43 PM

True, unless you want to see the messages even if you haven't opened your wallet in a week.

Rikki RATTOE at 2:44 PM

the only thing I was thinking was if you simply linked the image, somebody could just copy the link and text it off to everyone and the coupon isn't all that exclusive

UserJonPizza|MinePool.com|Mom at 2:44 PM

Maybe a mobile link-up for a easy way to see messages by just importing pubkey(edited)

RavencoinDev at 2:45 PM

Speaking of mobileWe are also getting close to a release of mobile that includes the ability to show assets held, and transfer them.Roshii has been hard at work.📷6📷1

Vincent at 2:46 PM

can be hidden also?

RavencoinDev at 2:47 PM

We're still finalizing the UI design but that is on the list of todos📷1

Under at 2:47 PM

Could we do zerofee mempool messaging that basically gets destroyed after it expires out of the mempool for real-time stealth mode messaging

corby at 2:48 PM

That's interesting!

RavencoinDev at 2:49 PM

There are other solutions available for stealth messaging, that's not what the devs had intended to build. It does sound cool though @Under

Under at 2:50 PM

📷 we’ll keep up the good work. Looking forward to the db upgrades. Will test this weekend

RavencoinDev at 2:50 PM

Thanks!That leaves us with 10 minutes for the Dev Kit!Corby has been working on expanding some of the awesome work that @Under has been doing.

corby at 2:52 PM

Yes -- all of the -addressindex rpc calls are being updated to work with assets

RavencoinDev at 2:52 PM

Hopefully we'll be able to post the source soon once the initial use cases are all working.

corby at 2:52 PM

so assets are being tied into transaction history, utxos, etc

RavencoinDev at 2:52 PM

The devs want to provide a set of API's that make it easy for web developers to build solutions on top of Ravencoin.VinX is investigating the possibility of using Ravencoin to power their solution.

corby at 2:53 PM

will be exposed via insight-api which we've forked from @Under

[Master] Roshii at 2:53 PM

Something worth bringing up is that you will be able to get specific asset daba from full nodes with specific message protocols.

corby at 2:54 PM

also working on js lib for client side construction of asset transactions

Tron at 2:55 PM

Dev Kit will be an ongoing project so others can contribute and extend the APIs and capabilities of the 2nd layer.📷3📷3

RavencoinDev at 2:55 PM

Will be posted soon to the RavenProject GitHub.

corby at 2:55 PM

separate thing but yes Roshii that is worth mentioning -- network layer for getting asset data

RavencoinDev at 2:55 PM

Again want to give thanks to @Under for getting a great start on the project

push | ravenland.org at 2:56 PM

Yes looking forward to seeing more on the extensive api and capabilities, is there a wiki on this anywhere tron?(as to prevent other people replicating eachothers work?)

RavencoinDev at 2:56 PM

The wiki will be in the project on GitHub

push | ravenland.org at 2:56 PM

im guessing when the kit is released, something will appear, okok cool

RavencoinDevat 2:57 PM

Any questions about the Web DevKit?

push | ravenland.orgToday at 2:57 PM

well, what kind of support will it give us, that would be nice, is this written anywhereI'm still relatively new to blockchain<2 yearsso need some hand holding i suppose 📷

bhorn at 2:58 PM

right, what are initial use cases of the devkit?

push | ravenland.org at 2:58 PM

i mean im guessing metamask like capabilitysome kind of smart contract, some automation capabilitiesrpc scriptsstuff like thiseven if proof of concept or examplei guess im wondering if my hopes are realistic 📷

RavencoinDev at 2:59 PM

You can see the awesome work that @Under has already don that we are building on top of.

push | ravenland.org at 2:59 PM

yes @Under is truly a herooki, cool

RavencoinDev at 2:59 PM

https://ravencoin.network/Ravencoin Block ExplorerRavencoin Insight. View detailed information on all ravencoin transactions and blocks.

push | ravenland.org at 2:59 PM

ok, sweet, that is very encouragingthanks @Under for making that code public

corby at 3:00 PM

It will hopefully allow you to write all sorts of clients -- depending on complexity of use case you might just have js lib (wallet functions, ability to post txs to gateway) or a server side project (asset explorer or exchange)..(edited)

Tron at 3:00 PM

Yeah, thanks @Under .

RavencoinDev at 3:00 PM

What's your GitHub URL @Under ?

push | ravenland.org at 3:00 PM

https://github.com/underdarkskies/ i believeGitHub· GitHubunderdarkskies has 31 repositories available. Follow their code on GitHub.📷

RavencoinDev at 3:00 PM

Yup!

push | ravenland.org at 3:00 PM

he is truly a hero(edited)

RavencoinDev at 3:00 PM

LOL

damn o'sgo missing everywhere

RavencoinDev at 3:01 PM

teh o's are hard... Just ask @Chatturga

RavencoinDev at 3:02 PM

Alright we're at time and the devs are super busy. Thanks everybody for joining us.

thanks guys

RavencoinDev at 3:02 PM

Thank you all for supporting the Raven community.📷6
