吴忌寒和澳本聪的“算力大战”,谁将胜出?

算力是军队,开发者是政府。比特币白皮书的设计是军队之间互相制衡,只有健壮的军队才能活下来,而政府的作用是让整套体系更高效。

算力大战将于11月16日0:40分开战。本次对战双方的两大阵营已经准备就绪,即以吴忌寒为代表的BCHABC阵营和以澳本聪为代表的BCHSV阵营,此时箭已在弦上,到点即发。

 

在经历了两大阵营代表人物的口水战之后,两大阵营即将迎来决定命运的一刻。手握算力的各个矿工们,到底会站到哪个阵营呢?这场“大战”谁才能取得最终的胜利?


“大战”的起源

去年8月1日,以吴忌寒为代表的比特大陆因不满比特币区块网络的种种限制,启动了针对比特币区块链的硬分叉项目——比特币现金(BCH)。随后在很短的时间内,比特币现金就以比特币10%总市值的规模,成为数字加密货币市场排名前四的币种。

 

彼时,Bitcoin ABC和nChain均成为BCH的开发团队。实际上直到今年8月1日BCH一周年活动上,吴忌寒还与nChain的首席科学家澳本聪同台出席。

 

但在不久后,双方的矛盾就出现在了公众的视野。

 

具体而言,以吴忌寒为代表的ABC派认为,在区块大小维持在32MB的情况下,应该让BCH的发展朝基础公链的方向走,以使BCH能够像EOS那样,拓展出更多的应用场景。开发团队宣称将在0.18.0版本增加共识更改,将增加新操作码,并计划在2018年11月15日实施硬分叉。

 

而代表nChain的澳本聪主导的SV派则提出了反对意见,希望BCH的发展仍遵循中本聪的白皮书所述,对操作码严格限制,专注在转账交易本身,并希望将区块最终扩容为128MB。

 

基于上述不同的思路,ABC派和SV派开发出了互相不兼容的共识协议,从而导致了此次的BCH硬分叉。

         

事实上,硬分叉的结果应该是出现两条同根但各自独立的链,但是由于SV派的澳本聪在近期的一次采访中扬言,要动用他所掌控的各种资源“发动战争”,甚至“用钱摧毁比特大陆”,这才导致了这场空前的“算力大战”。

 

这次算力大战争论的焦点,简言之,即BCH的未来。

“大战”双方的实力

目前,根据公开资料可知,ABC派(吴忌寒)和SV派(澳本聪)的背后都有无数的支持者,已知的如下:

 

ABC派:比特大陆、BitcoinABC 开发组、btc.top矿池、ViaBTC矿池、Coinex 交易所、bitcoin.com等。

 

SV派:nChain团队及其控制的BMG矿池、Coingeek矿池、SVpool矿池、Mempool矿池、okminer矿池等。

 

据Coin Dance网站上显示,澳本聪一方能够直接控制的算力(CoinGeek、SVP)达到了60%以上,加上那些支持他的矿池,如BMG、Mempool等,澳本聪得到的算力支持高达75%。如果从支持双方的矿池算力来看,目前SV派暂时领先,但比特大陆有大量比特币算力可随时切换至BCH。以此来看,情况最终如何还尚未可知。

 

但新疆矿工老李表示,得人心者得天下,SV派的提案是对矿工利益最大化的,其可以让矿工得到应得的报酬,而ABC派的提议,则是让矿工白干活。最终,矿工手里的“选票”也将投给SV派。ABC派明显是要架空算力、架空矿工,因为对他们来说,不受控的算力是很可怕的。

 

另一位北美矿工对猎云财经说:“算力是军队,开发者是政府。比特币白皮书的设计是军队之间互相制衡,只有健壮的军队才能活下来,而政府的作用是让整套体系更高效。军队全都是自带干粮来进行军备升级,通过提供服务来获取收入。这些军队都是雇佣军,所以军队的强弱很关键。在竞争中,只有强大的军队才能获得订单。”

 

BCH的分叉提醒矿工们算力即权力,大家逐渐意识到自己的重要性,每个矿工最终都会选择对自己利益最大化的战队。”新疆矿工小杨表示。

“大战”的背后


虽然猎云财经采访的矿工们认为SV派会得到矿工的支持,但币印矿池联合创始人朱砝却表达了不同的看法。

 

朱砝表示,从影响算力大战的因素“钱”的角度来看,烧钱——没有人会受益,一条链不需要太多的算力,再多都是浪费。从市场挖矿成本看,挖BTC的收益明显比挖BCH所得收益更高。澳本聪所谓的“烧钱论”明显是在开玩笑。让人放着更赚钱的BTC不挖,你得给人补贴,1T会亏7毛,一天要亏掉两千万。算力大战”打1小时,就得了。澳本聪只是吓唬对方,若真做了打的准备,没必要告诉别人。矿工的模式很简单,就是为了收益,所以没有必要为了双方的争斗,如果仅仅是双方入局,结果是一目了然的,更看好比特大陆一方。

 

无论哪一方会赢得算力“大战”,“入场”总有一定的原因。

 

数字货币分析师肖磊曾在此前的采访中称,数字货币硬分叉除了发展理念和信仰的问题,另一个完全是利益所驱动的。双方各自都希望BCH朝着自己最容易去推广和发展的那个方向改进,分叉实际上就是捍卫自己在整个体系内的话语权,以及争取到相应的利益。

         

胜出一方通过阻止生态分裂,使自己支持的协议版本继承整个网络经济生态的利益。难怪大家均在说,这次分叉是一群矿池大佬,为自己利益分配发起的一场争夺整个社区内利益最大化的战争。

 

天下熙熙皆为利来,天下攘攘皆为利往。算力之战的背后是资金的大作战,也是为利益而来的大作战。昔日的“兄弟”变成了博弈的双方,利益驱动是最主要的原因。

Hedge Fund Manager Brian Kelly Explains November 14th’s ‘Crypto Market Meltdown’

/latest/2018/11/hedge-fund-manager-brian-kelly-explains-november-14ths-crypto-market-meltdown/

On Wednesday (14 November 2018), Brian Kelly, the founder and CEO of digital asset investment firm BKCM LLC, explained yesterday’s “Crypto Market Meltdown”, which led to double-digit percentage losses for most of the major cryptocurrencies including Bitcoin, which sank to $5,569, its lowest price in over a year.

Yesterday, Kelly, on CNBC’s “Fast Money” show, was asked by host Melissa Lee to explain the reasons for the crypto markets going into “meltdown mode.”

Kelly started by pointing out that Bitcoin Cash (BCH) was about to a “hard fork”, i.e. an update to the protocol software “such that the software validating according to the old rules will see the blocks produced according to the new rules as invalid,” which means that “all nodes meant to work in accordance with the new rules need to upgrade their software.” And if “one group of nodes continues to use the old software while the other nodes use the new software, a split can occur.”

“Now, when you do a software upgrade, everybody usually agrees, but in this particular case, everybody is not agreeing about what that software upgrade should be. So, we’ve got ourselves a Crypto Civil War… and that has people in the market concerned.

So, what happened today? People are concerned that both Bitcoin and Bitcoin Cash networks might slow down, they might not work as well, that software upgrade might not go through, or if it does go through, we’ll end up with some chaos.

People started selling. That triggered stops. Everybody got concerned. And that’s what happened today.”

However, Kelly himself was not worried:

“In my view, very short term type of event. I think it’s probably an opportunity. In fact, we did some buying at my fund today.”

Lee then asked guest Meltem Demirors, the Chief Strategy Officer at CoinShares, if “there was a catalyst to the upside” after this “short-term selling event.” She answered:

“Absolutely… We had six months of Bitcoin and a lot of other assets trading sideways, and I think there were just a number of events that piled up that led to this mass release, the sell-off… My view is that it’s probably some institutions, some funds, deleveraging, taking some money off the table. Any time there are forks, things tend to trade weird and strange. So, I think people are trying to take some risk off the table. There are a number of exciting events coming up. In December, ICE’s new subsidiary, Bakkt, is going to launch… And then, in January, we’ll see Fidelity new crypto custody arm starting to operate.”

According to data from CryptoCompare, BTC is currently trading at $5,637 (down 1.81% in the past 24-hour period) and BCH is trading at $444.89 (down 8.74% in the past 24-hour period).

The Bitcoin Cash hard fork is scheduled to take place on November 15th 2018 around 16:40 UTC.

Binance Will Open USDC Deposits & Support USDC/BTC, USDC/BNB Trading Pairs Starting Nov 16th

Binance Will Open USDC Deposits & Support USDC/BTC, USDC/BNB Trading Pairs Starting Nov 16th

binance-will-open-usdc-deposits-support-usdc-btc-usdc-bnb-trading-pairs-starting-nov-16th

Malta-based digital asset exchange, Binance, has announced that it will starting listing Circle’s new stablecoin, USDC.

USDC/BTC, USDC/BNB Trading Pairs Start On Nov 16th

Binance, the world’s largest crypto exchange (in terms of daily trading volume), will open deposits for USDC and trading for USDC/BNB and USDC/BTC pairs on November 16th at 10:00 PM US Eastern Standard Time (EST).

Binance’s Medium blog post regarding the new listing mentions that “USDC has seen widespread adoption across the crypto ecosystem and is available globally on exchanges.”

Indeed, USDC and other stablecoins are increasingly being used by cryptocurrency traders and many new USD-backed tokens have entered the nascent digital asset markets.

Circle, Coinbase-Backed USDC

According to Binance’s estimates, the current circulating supply of USDC has exceeded $148 million and over “50 exchanges, protocols, platforms, applications and wallets” now support Circle’s USD-backed coin.

Moreover, Binance’s blog mentions that Circle Internet Financial and San Francisco-based crypto exchange, Coinbase, believe that the USDC will be increasingly used by traders – as market participants are looking for more “transparent and compliant USD tokens.”

As covered, Circle launched the USDC on September 26th, 2018 and the Goldman Sachs-funded American fintech stated that the “USD Coin” is a fully collateralized USD-backed cryptocurrency.

CENTRE Consortium Established To Promote Stablecoin Adoption

Notably, Circle developed the USDC through a collaborative effort with Coinbase and both companies established the CENTRE Consortium – “with the goal of establishing a standard for fiat on the internet.”

The CENTRE Consortium also aims to provide a governance framework for cryptoassets, in addition to a “network for the global, mainstream adoption of fiat stablecoins.”

Similar to how most stablecoins are used, customers “can tokenize US dollars into USDC and redeem USDC into US dollars through both Circle and Coinbase”, Binance’s blog explained.

USDC Addresses May Be “Blacklisted” In Cases Of Suspicious Or Illegal Activity 

As CryptoGlobe reported recently, Circle has explained in its user agreement that the American fintech is able to freeze user funds (USDC deposits), terminate accounts, and report accounts in case of suspicious activity.

Circle’s user agreement reads in part:

Circle reserves the right to “blacklist” certain USDC addresses and freeze associated USDC (temporarily or permanently) that it determines, in its sole discretion, are associated with illegal activity or activity that otherwise violates the terms of this User Agreement (“Blacklisted Addresses”). In the event that you send USDC to a Blacklisted Address, or receive USDC from a Blacklisted Address, Circle may freeze such USDC and take steps to terminate your USDC Account.

South Korea’s Gyeongbuk Province Launches ‘Special Committee’ to Create Blockchain Hub

The government of South Korea’s Gyeongbuk province has launched a “Blockchain Special Committee” with the goal of creating a blockchain hub in the region, local media outlet Daily News reported Nov. 14.

North Gyeongsang Province, also known as Gyeongbuk, plans to create a blockchain hub, inviting 40 domestic and foreign experts in the industry to consult on the project.

Lee Cheol-uoo – a former member of the National Assembly of South Korea and current governor of the province – explained to local media the aims of the newly established committee as attracting investment for blockchain related businesses in the region. He also  noted:

“In order to nurture the blockchain industry, we will work with the special committee, composed of domestic and international experts, to preemptively respond and establish strategies.”

The Committee’s establishment is not the region’s first venture into blockchain. This summer, the province’s government announced plans to issue its own local cryptocurrency, dubbed Gyeongbuk Coin, which will reportedly be accepted by merchants across the region.

South Korea as a whole has recently signalled a push for development in blockchain. As Cointelegraph reported last week, the country’s government ruled to increase the federal budget for developing blockchain technology for the year 2019 to approximately $35 million,  a three-fold increase from this year.

Coinbase CTO Says Time May Finally Be Right for At-Home Crypto Mining

Timing is everything, even in crypto.

That’s why a notable pioneer in consumer bitcoin mining is backing a startup seeking to take another stab at popularizing at-home crypto mining, a business with a long history of abrupt ends for early entrants that includes some of the industry’s best known busts (Butterfly Labs, Alpha Technology and GAW Miners among them).

Still, Coinbase CTO Balaji Srinivasan is betting a new startup called Coinmine, which announced pre-orders for its first home miner on Wednesday, might be able to reverse this trend.

Srinivasan said:

“The big difference with decentralized mining in 2018 is that there are now so many different coins and tokens out there that it’s almost certainly possible to make a profit – or at least mine a decent amount of some crypto – via a decentralized home mining device like Coinmine.”

It’s a notable perspective given that Srinivasan previously founded 21.co, a startup that emerged from stealth in 2015 with an ambitious plan to embed bitcoin miners in everyday devices. With that experience in mind, Srinivasan backed Coinmine during its angel round, while the company was still very much under wraps.

With its announcement, it revealed that Coinbase Ventures is now also a backer.

No stranger to home mining, 21.co attempted to foster an ecosystem of home mining by building the 21 Bitcoin Computer, built both to mine and run bitcoin-based apps.

21.co retired support for the device in 2017 and later pivoted to become Earn.com, a company that allowed people to earn bitcoin for replying to emails and completing other tasks. Earn was later acquired by Coinbase, at which point Srinivasan took on his current role.

More coins, more opportunities

Still, underlying the investment is Srinivasan’s belief in a diversified crypto economy.

Despite his prior company’s pivot away from mining, Srinivasan believes that crypto has changed in two substantial ways that make home mining more feasible in 2018 than 2015.

“Back in 2015 only bitcoin had any significant share, so the viability of any decentralized mining approach was benchmarked against BTC alone as opposed to 1,000-plus new digital assets,” he said.

Thanks to a boom that has brought to market thousands of cryptocurrencies, the technology’s enthusiasts don’t have to compete futilely against Bitmain and other giant pools.

“The big difference with decentralized mining in 2018 is that there are now so many different coins and tokens out there that it’s almost certainly possible to make a profit – or at least mine a decent amount of some crypto – via a decentralized home mining device like Coinmine,” Srinivasan wrote.

BoostVC cofounder Adam Draper spoke to similar themes when he told CoinDesk he’d backed his 100th crypto startup. He pledged to back 100 bitcoin startups in 2015, but he also saw the industry change into one where there was more to crypto than bitcoin.

Innovative new coins alone would not be enough to make Coinmine worth it, though. Srinivasan said it’s also important that so many of these new tokens have been judged worthy enough by the market to maintain significant valuations.

Srinivasan sees Coinmine as a bet on more worthwhile coins to come. “There will likely always be some asset or set of assets that Coinmine can mine which makes a profit,” he wrote.

Changing with the times

Remote updates will be key to Coinmine’s success, in Srinivasan’s view.

He’s optimistic about Coinmine’s ability to add new coins later, and he foresees a future where the company could play a key role in launching new tokens. He said, “If Coinmine gets to substantial scale, you might even see some new digital assets in the future with ASIC-resistant hash functions launching directly on Coinmine.”

Notably, the system is built to run two tokens: one proof-of-work, one proof-of-stake, though the latter will only be enabled with updates coming in 2019. The anticipated networks for staking currently listed on its website are: tezos, casper, dfinity, filecoin, spankchain, polkadot, cosmos and foam.

Still, users will pay a high price for that ease and convenience. As CEO Farbood Nivi explained to CoinDesk, Coinmine will automatically put users into mining pools. It’s one more way of making the product plug-and-play, but it also cedes a significant amount of control.

Further, the company will take a 5 percent cut of users’ earnings as they mine, according to a spokesperson for Coinmine.

As expected, hardcore crypto enthusiasts cast a lot of doubt on the new product’s potential for return on investment. Rob Paone’s tweet was representative, contending that for a $799 user, users could expect to earn roughly $5 per day, not counting whatever electricity costs accrued.

“Sounds like it’s more of a fun/hobby purchase than a purchase for expected return,” Paone wrote.

That does seem to be the market Coinmine is aiming for: people for whom $799 is not a major investment and who believe in crypto enough that they think it will eventually see major gains (but also aren’t interested enough to learn how to run their own rigs).

Srinivasan agreed, arguing that crypto should welcome Coinmine into the market as a new resource for increasing the security of various networks.

He wrote:

“I believe that decentralized mining is an important idea and worth trying again. It’s mining as Satoshi intended: many devices around the world with no single point of failure.”

Coinshares Exec: Bitcoin in Financial Crisis, Altcoins in Liquidity Crisis

The jaws of crypto investors fell to the floor on Wednesday, as cryptocurrencies, such as Bitcoin, Ether, and XRP, plummeted to establish new year-to-date lows. Although some cynics feared this rapid bout of capitulation for months, for many investors, this strong sell-side pressure, which saw BTC fall under $5,800, came straight out of left field.

To bring clarity to the precarious market conditions, CNBC Fast Money rebooted its crypto segment, which was on a multi-week hiatus, to subsequently call on Meltem Demirors to make a guest appearance.

Recent Bitcoin Crash Was A Result Of Institutions “Deleveraging”

Demirors, who currently acts as Coinshares’ chief strategy officer, first drew attention to the multi-month non-action in crypto markets, highlighting BTC’s stability and failure to trade out of a range. She explained that this lack of volatility, coupled with a “number of events,” was likely the catalyst that led to this strong sell-off, which shaved upwards of $20 billion off the aggregate value of all digital assets.

The most notable of these events, as Demirors speculated, was institutions and crypto-friendly hedge funds deleveraging their positions, or in other words, liquidating a portion of their cryptocurrency holdings. She added that Bitcoin Cash’s impending fork, which is slated to occur on Thursday, may have catalyzed wonky behavior in the market, likely referencing BTC’s peculiar price action during the original Bitcoin Cash hard fork on August 1st, 2017.

Although her statements painted a dark picture for the cryptocurrency ecosystem, Demirors explained that the arrival of Bakkt’s physically-backed Bitcoin futures in December, along with the subsequent launch of Fidelity’s digital asset subsidiary, may be beneficial for crypto over the long haul.

Still, the Digital Currency Group’s former vice president went on to note that Bitcoin is in a “financial crisis,” while altcoins are in a “liquidity crisis.” The latter situation, in Demirors’ eyes, is arguably worse, as she went on to point out that altcoin pairs have seen close-to-zero activity. Moreover, she added that the war chests of projects have begun to empty en-masse, indicating that a further sell-off for altcoins could be in the pipes as startups seek to cut costs, fire employees, and liquidate their crypto holdings.

Although startups will make moves to stay afloat, unfortunately, the Coinshares executive noted that due to crypto being a “speculator’s game,” a number of altcoins will eventually collapse to $0.

Interestingly, Demirors’ comments are somewhat coherent with the sentiment she put forth in her previous guest segments on Fast Money’s panel. In mid-August, the Coinshares executive alluded to the fact that crypto isn’t poised for a bull run. She first likened this industry to the Internet’s nascent years, before claiming that “new technologies that shift the paradigm,” such as cryptocurrencies and blockchain technologies, are neither fully understood nor adopted overnight.

Regardless, at the time and during her most recent CNBC appearance, Demirors maintained that she sees long-term potential for this innovation. The industry insider previously explained that cryptocurrencies have a potential for a substantial move to the upside, drawing attention to Bitcoin’s prospects of replacing M1 and M2 (global money supply) and Ethereum’s ability to usurp the global market for computing capacity.

The Daily: Coinbase Blesses Binance, Game Day for BCH

It’s a big day for Bitcoin, though quite what flavor of Bitcoin remains to be seen. By the time the dust has settled on this historic Thursday, we should have an idea of which way the Bitcoin Cash hash war has swung. In this edition of The Daily, we round up the best tools for monitoring the fork as it happens and take a look at Ledger’s natty new range of hardware wallets.

Bitcoin Cash Has Its Day of Reckoning

At around 11:40 a.m. EST the Bitcoin Cash (BCH) network will fork to become two. Quite what happens after that is anyone’s guess, although there have been plenty of attempts to predict the ways this hashpower battle could play out. Rather than add to the noise by speculating on whether Bitcoin ABC or Bitcoin SV will become the dominant chain, we’ll settle for linking to resources for where you can watch the drama unfold.

The Daily: Coinbase Blesses Binance, Game Day for BCH

Cash.coin.dance shows hashrate estimations for the competing BCH implementations, while Bitmex Research has created Forkmonitor.info. Click on the Bitcoin Cash tab at the top to see which BCH build is in front. We’ve also published a roundup of the key arguments from each side of the divide, plus a list of how numerous platforms and services are handling the fork. Whether you’re a BCH proponent, opponent, or merely a casual spectator, Nov. 15 promises to be a seismic day in Bitcoin history.

Coinbase Endorses Binance Listing

It’s not every day you log onto Twitter to find America’s largest exchange shilling the world’s largest one. That’s what happened, in a fashion, after Binance listed Circle’s USDC. Coinbase is part of the Centre Consortium behind the stablecoin, and has thus found itself tweeting its support of its great rival. The stablecoin will be listed on Nov. 17 and paired against USDC/BNB and USDC/BTC, taking the number of stablecoins on the platform to four.

Ledgers Are the New iPhones

Hardware wallet manufacturer Ledger has been perfecting the aesthetics of its devices with each iteration. Just when you thought the French manufacturer might be running out of ways to rethink the USB stick, it goes and releases another sleek version of its popular Nano S. A fortnight ago, Ledger released its White Paper Edition, which came with a miniature version of Satoshi Nakamoto’s seminal whitepaper to coincide with its 10th anniversary. Now it has followed this up with the release of half a dozen color options for the Nano S.

The Daily: Coinbase Blesses Binance, Game Day for BCH

While the move might sound like the slick marketing of a company trying to move more units, there is a kind of rationale behind the multicolored Nanos. The company explains: “When you are managing a wide range of assets, using multiple Ledger Nano S enables you to dedicate each one to specific applications. With different colors, you can now easily identify any of your Ledger Nano S.”

EOS沦为“博彩”公链,开发者频遭黑客攻击丨得得分析

以太坊上共有1272款DApp,将近10倍于EOS公链,但是EOS的平均日活和成交量却10倍于以太坊,而且博彩竞猜类游戏贡献着90%以上的交易额。对于沦落为一条“博彩”公链的EOS,自然少不了黑客的袭扰。

近日,EOS公链频繁爆出安全问题,黑客攻击者利用多种巧妙的手段去攻击部署在EOS上的区块链游戏,由于众多开发者的“风控”能力较低,从而使得黑客可以轻松将账户系统中的资金转走。


一时间,关于EOS DApp生态安全问题的讨论甚嚣尘上。链得得发现,此次在EOS公链上爆发的安全问题依然集中在竞猜博彩类游戏项目上。而对于EOS公链来说,博彩类游戏遭到的攻击已经完全影响到EOS整个网络的安全,因为博彩类游戏在EOS公链中贡献了90%以上的交易量。

黑客攻击回顾


首先,我们先来回顾一下近日在EOS公链上陆续爆出的黑客攻击事件。


10月15日午间,知名EOS公链博彩游戏平台EOSBet遭遇恶意攻击,损失巨额EOS。安全公司PeckShield分析发现,黑客利用EOSBet合约在检验收款方时存在的漏洞“伪造转账通知”,从EOSBet合约eosbetdice11中获利138,319.7995EOS。更可怕的是,在EOSBet上线十天内就遭到了3次攻击。


10月31日凌晨,EOSCast游戏遭到黑客连续9次的强势攻击,7万多EOS被黑客转走。黑客这次主要采取了一种“假EOS”的攻击手段,可理解为,黑客创建了一种基于EOS的代币,并将其命名为“EOS”,开始大量给被攻击合约账号转账假EOS代币,由于合约没有检测EOS的发行方,误把“假EOS”转账视为真的,进而调用了合约中的transfer函数,按照开奖流程分配了奖金。


11月8日凌晨1点,EOS公链上又一款竞猜类游戏FFgame遭遇了黑客攻击,黑客账户jk2uslllkjfd向FFgame游戏合约 (eoswallet415)发起多达304次攻击,共计获利1,331.2922个EOS。这次攻击主要是通过“写合约代码计算出游戏中奖规律”实施攻击。


10月10日,EOS竞猜游戏EOSDice再遭黑客攻击,损失4,633个EOS。此次EOSDice遭攻击原因同样是由于“随机数问题被攻破”。11日早,DApp EOS.WIN 也被攻击者(lockonthecha)攻破。


安全公司PeckShield安全专家华南告诉链得得,“假通知”、“假EOS”对于开发者来说是很低级的错误。抛开这些涉及金额较大的黑客攻击事件,在10月份,黑客利用不同的账户在一直侵袭着EOS公链。直到10月15日,博彩游戏EOSBet被黑客盗走14万EOS后,才逐渐引起市场关注。而在此之后,黑客玩法不断变化,针对EOS的攻击手段愈加猖獗。而在近一个月内,已经先后有超5款EOS竞猜类游戏遭到了攻击。

EOS沦为“博彩”公链


关于EOS的安全问题,在主网上线前就被安全公司360揪出“史诗级漏洞”,在后来的运行中,受之于用户对于EOS公链此前大肆宣传和现实使用中的落差,EOS在这半年的运行可以概括为“不温不火”。


之后是在9月份,以太坊网络中一款叫做“Fomo3D”的资金盘游戏开启吸金模式,从用户关注度到以太坊的资金流量,都围绕在了这款游戏上。不出意外的是,当时因巨额奖池的诱惑,黑客选手也将魔爪伸了进来,大奖空投遭黑客疯狂盗取。


随后因安全问题频发,玩家热情逐渐消退,以太坊博彩类游戏重归于寂静。但是在一个月后,EOS平台上复制出现的竞猜、博彩类游戏同样在复制着以太坊“受害者”角色,资金游戏的运行终究没有逃出黑客选手的关注,黑客开始频繁袭扰EOS。链得得发现,黑客的突然出现与DApp的活跃情况保持着高度的相关性。


据DappReview显示,截至11月11日,EOS公链中运行着158款DApp,其中“抽奖”类别的DApp有77款。如果按“24h成交额”升序发现,前50名中99%是抽奖类游戏。而对比以太坊,就可以更直观看到黑客为何在EOS公链上这么活跃。


EOS与以太坊DApp对比图(抽奖类)


链得得统计发现,同样是“抽奖”类游戏,以太坊无论是从日活还是当日成交额来看,都完败于EOS。甚至于在以太坊活跃的前十大DApp,日活人数都不及EOS的其中一个DApp。从另一个维度对比发现,以太坊上共有1272款DApp,将近10倍于EOS公链,但是EOS的平均日活和成交量却10倍于以太坊,而博彩竞猜类游戏贡献着90%以上的交易额。可以说,EOS公链已经沦落为一条“博彩”公链。


PeckShield华南告诉链得得,过去Fomo3D所在的以太坊公链交易频次低,而且由于以太坊本身的架构就决定了其每次交易都需要去消耗一定的Gas费。但EOS网络不需要交易费用,在一定程度上促进了游戏开发者迅速转身到EOS平台上来。


链得得通过DAppRadar查询发现,不同于此前一直由“博彩类”占据交易额前列的情况,以太坊排名靠前的应用已经逐渐由“交易所”所代替。


华南补充道,无论是以太坊还是EOS,高匿名性的特征给到了作恶非常大的优势。此外,由于EOS主网在6月15日才正式启动,对于游戏开发者来说,编码、语言和框架等诸多因素都是新的事物,难免会犯一些非常低级的错误。“之前有一些游戏,甚至用了错误的开源代码。”


华南提醒开发者,建议参考官方开发文档以避免低级错误;此外,对于所有的产品在上线前都需要找安全审计公司进行审计,把安全风险降到最低。而对于所有博彩类游戏来讲,一个稳定的安全风控系统或是自动预警系统是不可少的,要保证在黑客攻击过程中及时止损。(本文独家首发链得得App

在实际应用当中,最重要的是区块链技术在具体场景中产生的价值。但是需要注意的是,区块链行业中存在大量的泡沫,作为一个to B的服务,到现在依然没有缺乏相关的标准,无法将区块链所带来的价值进行量化。

十一月的深圳,正午天气依然炎热,但在距离皇岗口岸不足3公里的岗厦地铁站外,依然有一群妇女在街头吆喝着。她们戴着遮阳用的宽檐帽,不住的观察过往的行人,并在任何合适的时机凑上去问一声:“开发票吗?”


她们兜售的主要是增值税发票,用于个人报销,餐饮、交通、办公用品都是她们的“营业范围”。如果要更大额度的,她们也开得出来,足够满足企业的抵税需求。


作为经济特区,深圳交通发达,企业众多,进出口贸易繁忙。这也催生了虚假发票的出现。仅去年,深圳市国税局等四部门就共捣毁11个团伙,抓捕犯罪嫌疑人68人。全国各地的税务机关每年都投入大量的人力物力,整治虚假发票市场,但是就像“割韭菜一样”,查了一波又一波始终不能根治问题。


8月10日,在国家税务总局的指导下,深圳市税务局携手腾讯公司落地区块链电子发票项目,并宣告深圳成为全国区块链电子发票试点城市。


据了解,在首期试点应用中,深圳市税务局、腾讯、金蝶软件三方合作,打造了“微信支付——发票开具——报销报账”的全流程发票管理应用场景。


前电子发票以电子数据的形式保存,很容易被重复下载和打印,而且很容易通过PS技术篡改信息,容易造成电子发票重复报销、重复入账以及虚假报销、虚假入账的潜在风险。


腾讯区块链业务总经理蔡弋戈

11月5日,链得得App在2018深圳区块链技术与应用大会期间对腾讯区块链业务总经理蔡弋戈进行了独家专访,他向我们介绍了腾讯在区块链技术落地方面的探索。


蔡弋戈告诉链得得App,企业应用区块链的核心是“解决问题”。这些问题的特征在于,在具体的业务场景中存在信任的问题。因为无法信任其他节点,传统的方式需要通过各种各样的手段来进行“共识”,提高了成本,降低了效率。所以在应用场景中只要存在多方协作中的信任问题,这种情况我们就可以认为它具备了利用区块链进行改变的前提。


蔡弋戈表示,深圳市落地区块链电子发票就是一个很好的应用场景。“区块链电子发票具有全流程完整追溯、信息不可篡改等特性,与发票逻辑吻合,能够有效规避假发票,完善发票监管流程,涉费信息更加安全。”区块链电子发票将连接每一个发票干系人,可以追溯发票的来源、真伪和报销等信息,让发票信息全场景流通成为现实,解决发票流转过程中一票多报、虚报虚抵、真假难验等难题,从根源上解决虚假发票产生的土壤。


所以,在实际应用当中,最重要的是区块链技术在具体场景中产生的价值。但是需要注意的是,区块链行业中存在大量的泡沫,作为一个to B的服务,到现在依然没有缺乏相关的标准,无法将区块链所带来的价值进行量化。蔡弋戈说:“在行业内,大家各说各话,然后各自也不知道说到底是有一个什么样的标准,所以我觉得还是要回归到标准的建设。”


蔡弋戈透露,工信部直属的中国信息通信研究院正在研究制定认证标准。认证标准中将包含对区块链性能、稳定性、安全性的量化指标。他认为,标准一旦制定完成,会使得区块链技术的落地进程大大提高。(本文独家首发链得得App
