Precio de Ethereum Classic demuestra resistencia a pesar de ataques

La red Ethereum Classic sufrió no uno, sino tres ataques del 51%: el primero tuvo lugar el 1 de agosto, el segundo el 6 de agosto y el tercero el 29 de agosto, a pesar de ello los inversionistas se han mantenido firmes, mientras se anuncian medidas para fortalecer la red de esta criptomoneda. Te detallamos lo que viene sucediendo con esta cripto en la siguiente nota.

Septiembre 9.- A pesar de tres “ataques del 51%”, el precio de Ethereum Classic ha demostrado una fuerte resistencia. Aunque ha bajado un poco su persistencia puede indicar que la seguridad no es una prioridad máxima para los inversores que buscan unirse a una carrera alcista en el mercado de cifrado.
Sin embargo, algunos advierten que, a menos que mejore su cadena de bloques y se haga más segura, los ataques adicionales a Ethereum Classic podrían desencadenar una liquidación del mercado y provocar un colapso de su activo digital.
Para la seguridad de una red blockchain, un "ataque del 51%" es tan malo se escucha. Es cuando una sola entidad obtiene el control de la mayor parte de la potencia informática de la red, lo que le permite desviar unidades adicionales de la moneda en lo que se conoce como doble gasto.
Por lo tanto, sería lógico pensar que tres ataques exitosos del 51% en un mes contra la cadena de bloques Ethereum Classic podrían afectar la confianza de los inversores.
Pero los precios del token ETC nativo del proyecto en realidad no se han visto afectados: una señal que los comerciantes podrían estar menos preocupados por las vulnerabilidades de seguridad que por una ganancia rápida en los mercados de criptomonedas en rápido movimiento.
En el momento de la publicación, ethereum classic se cotiza a 5.06 USD, una caída de aproximadamente un 27% en los últimos 30 días, al mismo tiempo que bitcoin ha bajado un 15%.

Tres ataques del 51% en un mes

Para la cadena de bloques Ethereum Classic, los ataques del 51% han sido una amenaza durante mucho tiempo. A diferencia de Ethereum, del cual se bifurcó con fuerza, la red Ethereum Classic está comprometida con el algoritmo de consenso de Prueba de trabajo (PoW), que también es utilizado por Bitcoin.
Para redes grandes como Bitcoin, un ataque del 51% es altamente costoso dada la enorme cantidad de poder computacional que requiere PoW para hacerlo con éxito. El hashrate de Ethereum Classic es mucho más pequeño, lo que lo hace mucho más vulnerable a este tipo de situaciones.
Al cierre de esta edición, el hashrate de Ethereum Classic era de 1,668 terahash por segundo, mientras que el de Bitcoin estaba en 117,95 exashes por segundo, según BitInfoCharts.

¿Qué es Ethereum Classic?

Ethereum Classic es el producto de un Hard Fork después de que la red Ethereum se dividió de diferentes maneras tras un pirateo en 2016. La cadena de bloques basada en PoW ha estado persiguiendo a Ethereum, que ahora representa la criptomoneda número 2 por capitalización de mercado.
Ethereum planea cambiar su algoritmo en algún momento del próximo año. En un tweet el 2 de septiembre, el fundador de Ethereum, Vitalik Buterin, argumentó que el algoritmo de prueba de participación (PoS) planificado de Ethereum le da una ventaja "fundamental clave" sobre PoW.
"En PoW, por otro lado, un atacante exitoso puede simplemente atacar una y otra vez, sin forma posible de eliminar su hardware sin eliminar el hardware de todos los demás".
Durante el mes de agosto, la red Ethereum Classic sufrió no uno, sino tres ataques del 51%: el primero tuvo lugar el 1 de agosto, el segundo el 6 de agosto y el tercero el 29 de agosto.
NiceHash, un corredor de hashpower, reconoció que su plataforma puede haber facilitado los recientes ataques del 51%, en una publicación de blog el 1 de septiembre, pero también concluyó que tales ataques no se pueden prevenir o mitigar en una “solución de prueba de trabajo verdaderamente descentralizada”
"Lo único que se puede hacer es hacer que el precio de un ataque sea más alto que la recompensa del atacante", agregó la publicación.
La red Ethereum Classic también sufrió un ataque del 51% a principios de 2019, lo que llevó al intercambio de cifrado Coinbase a detener todas las transacciones, retiros y depósitos de ETC en ese momento.
James Wo, fundador de ETC Labs, la organización líder que respalda la red Ethereum Classic, dijo a través de un portavoz que su equipo ha estado tratando de mejorar la seguridad de la red el año pasado, incluida la expansión del equipo de desarrollo central de la red y la asociación con empresas. como Chainlink, Swarm y Bloq.
La compañía anunció dos nuevas contrataciones el 3 de septiembre para el equipo de desarrollo central de ETC.
"Estos desarrollos y asociaciones están trabajando para impulsar rápidamente el avance de ETC y garantizar un futuro brillante para la red", dijo Wo, quien agregó que el precio de ETC se ha mantenido "fuerte" incluso con los recientes ataques del 51%.
De hecho, los ataques no han tenido un impacto significativo en sus precios, lo que generó una pregunta: ¿por qué alguien pondría dinero en un token cuando su seguridad no está garantizada?
Un gran porcentaje de los titulares de ETC recibieron sus tokens involuntariamente después de la división de la cadena de Ethereum y, como resultado, el precio de ETC se ha mantenido estable durante los últimos años simplemente porque muchos titulares de ETC han ignorado tomar medidas.
Ethereum Classic aborda el análisis de equilibrio. Solo 610 direcciones (0.03% del total) controlan el 86% de todo el Ethereum Classic. Tasa de referencia: 1 ETC = $ 5.10
“Muchas personas simplemente están sentadas y tal vez no necesariamente estén pensando en operar en ETC o no necesariamente monitoreando activamente su transición”, dijo Meltem Demirors, director de estrategia de CoinShares. "Porque muchas personas que tienen activos de un tenedor realmente no tienen ningún incentivo para venderlos a menos que el valor aumente drásticamente".
Citando el hecho de que una gran cantidad de carteras Ethereum Classic han estado inactivas, Demirors dijo que algunos titulares de ETC pueden no ver el valor de vender o incluso reclamar su ETC.

Emet y Faswet responden son seguridad garantizada

Este análisis se hace necesario debido a la incertidumbre que se genera alrededor del mundo criptográfico y que suele simplificarse sosteniendo que las criptomonedas son activos que no tienen futuro.

Decred Journal — May 2018

Note: New Reddit look may not highlight links. See old look here. A copy is hosted on GitHub for better reading experience. Check it out, contains photo of the month! Also on Medium

Development

dcrd: Significant optimization in signature hash calculation, bloom filters support was removed, 2x faster startup thanks to in-memory full block index, multipeer work advancing, stronger protection against majority hashpower attacks. Additionally, code refactoring and cleanup, code and test infrastructure improvements.
In dcrd and dcrwallet developers have been experimenting with new modular dependency and versioning schemes using vgo. @orthomind is seeking feedback for his work on reproducible builds.
Decrediton: 1.2.1 bugfix release, work on SPV has started, chart additions are in progress. Further simplification of the staking process is in the pipeline (slack).
Politeia: new command line tool to interact with Politeia API, general development is ongoing. Help with testing will soon be welcome: this issue sets out a test plan, join #politeia to follow progress and participate in testing.
dcrdata: work ongoing on improved design, adding more charts and improving Insight API support.
Android: design work advancing.
Decred's own DNS seeder (dcrseeder) was released. It is written in Go and it properly supports service bit filtering, which will allow SPV nodes to find full nodes that support compact filters.
Ticket splitting service by @matheusd entered beta and demonstrated an 11-way split on mainnet. Help with testing is much appreciated, please join #ticket_splitting to participate in splits, but check this doc to learn about the risks. Reddit discussion here.
Trezor support is expected to land in their next firmware update.
Decred is now supported by Riemann, a toolbox from James Prestwich to construct transactions for many UTXO-based chains from human-readable strings.
Atomic swap with Ethereum on testnet was demonstrated at Blockspot Conference LATAM.
Two new faces were added to contributors page.
Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: coinmine.pl share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per dcred.eu. Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.

ASICs

Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 (ibelink.co). Shipping starts from June 5. Some concerns and links were posted in these two threads.

Integrations

A new mining pool is available now: altpool.net. It uses PPLNS model and takes 1% fee.
Another infrastructure addition is tokensmart.io, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)
CoinPayments, a payment processor supporting Decred, developed an integration with @Shopify that allows connected merchants to accept cryptocurrencies in exchange for goods.

Adoption

New merchants:
An update from VotoLegal:
michae2xl: Voto Legal: CEO Thiago Rondon of Appcívico, has already been contacted by 800 politicians and negotiations have started with four pre-candidates for the presidency (slack, source tweet)
Blockfolio rolled out Signal Beta with Decred in the list. Users who own or watch a coin will automatically receive updates pushed by project teams. Nice to see this Journal made it to the screenshot!
Placeholder Ventures announced that Decred is their first public investment. Their Investment Thesis is a clear and well researched overview of Decred. Among other great points it noted the less obvious benefit of not doing an ICO:
By choosing not to pre-sell coins to speculators, the financial rewards from Decred’s growth most favor those who work for the network.
Alex Evans, a cryptoeconomics researcher who recently joined Placeholder, posted his 13-page Decred Network Analysis.

Marketing

@Dustorf published March–April survey results (pdf). It analyzes 166 responses and has lots of interesting data. Just an example:
"I own DECRED because I saw a YouTube video with DECRED Jesus and after seeing it I was sold."
May targeted advertising report released. Reach @timhebel for full version.
PiedPiperCoin hired our advisors.
More creative promos by @jackliv3r: Contributing, Stake Now, The Splitting, Forbidden Exchange, Atomic Swaps.
Reminder: Stakey has his own Twitter account where he tweets about his antics and pours scorn on the holders of expired tickets.

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.

Markets

The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

Relevant External

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.
Circle, the new owner of Poloniex, announced a USD-backed stablecoin and Bitmain partnership. The plan is to make USDC available as a primary market on Poloniex. More details in the FAQ.
Poloniex announced lower trading fees.
Bittrex plans to offer USD trading pairs.
@sumiflow made good progress on correcting Decred market cap on several sites:
speaking of market cap, I got it corrected on coingecko, cryptocompare, and worldcoinindex onchainfx, livecoinwatch, and cryptoindex.co said they would update it about a month ago but haven't yet I messaged coinlib.io today but haven't got a response yet coinmarketcap refused to correct it until they can verify certain funds have moved from dev wallets which is most likely forever unknowable (slack)

225 Good YouTubers & 30 Bad Ones! (Help Me Verify)

I am finalizing my list for CryptoInfluence - The link is a beta version.
I've made several topics on this Reddit asking for input and received a tons of suggestions!
This site is an offshoot of my popular Socialbook.io platform which is used by YouTubers to help get Sponsorships/Partnerships from brands. Brands use the platform search for YouTubers to advertise their products. Once the list is narrowed down they view their profiles and can choose to purchase their advanced profiles in order to view their audience demographics & to contact them.
YouTubers get 50% of the price paid by brands to view their profiles & contact them. They keep 100% of whatever sponsorship deal they negotiate. This has been very successful so far. Up until recently the most popular searches were were Gaming & Fashion YouTubers.
Over the summer we never received any requests for Crypto Influencers. Now we get 12 a day, making Crypto YouTubers our top category!
The biggest complaint is that brands keep choosing the wrong ones and getting scammed. The Crypto Boom is so new that their are not very many "trusted" channels yet. There are no million+ channels. Most of the channels are a few months old between 1-20k subscribers. Its very difficult for them to choose.
The site should do 3 things:
1. Allow brands to easily find quality YouTubers to partner with. Leading to both sides to profit.
2. Blacklist the scammer channels, and keep them from monetizing their channels. (There will be a form to report Scammers)
3. Clear out my inbox ;-)
Below is the current list, sorted by number of subscribers (except the bottom 10 or so). Please help me verify any scammers. The ones I really need help with are at the very below. Also, if you know of any good channels that I don't have listed please let me know! Thanks a bunch!
When the site is done, the channels will be ranked via an algorithm that is less dependent upon subscriber numbers, and more dependent upon relevant content, activity, and audience engagement. This should be able to properly rank that "Good" channels from the more "Mediocre" ones. There will also be a sorter (similar to our advanced search) where you can re-list the channels based on audience demographics, country, language, average views, etc.
