Stanford computer scientists have founded the Center for Blockchain Research, an initiative dedicated to researching and understanding a technology that promises to fundamentally change how people and companies make deals and complete financial transactions over the internet.

Led by Dan Boneh and David Mazières, both professors of computer science, the center’s inaugural faculty will also include Alex Aiken, David Dill, John Mitchell, Tim Roughgarden and law school faculty Joe Grundfest.

“Blockchains will become increasingly critical to doing business globally,” said Boneh, the Rajeev Motwani Professor in the School of Engineering, and an expert on cryptography and computer security. “Stanford should be at the forefront of efforts to improve, apply and understand the many ripple effects of this technology.”

The center will bring university scientists and industry leaders together to develop best practices for this burgeoning and potentially transformative field. In addition to research, center scientists are creating courses to help future students and working professionals use blockchain to develop financial instruments, protect intellectual property, manage vital records and more.

“Blockchain massively lowers the barriers to creating tradeable, digital assets,” Mazières said. “It allows individuals who don’t know each other, or even trust one another, to make irreversible transactions in a whole variety of fields in a safe and secure way.”

Because blockchain allows traceability, security and transparency, many companies are exploring how it might be used to improve supply chain management, expedite real-estate transactions and the transfer of deeds, or modernize voting technology. Thanks to its best-known application as a cryptocurrency, blockchains could be used to provide safe, secure vouchers to help refugees purchase food.

Blockchain works by creating the digital equivalent of a ledger book of transactions, and distributing multiple copies of identical ledgers over the internet. Each time a new transaction occurs, a data block is added to the chain of information stored in each and every copy of the ledger. This decentralized and highly distributed approach ensures that past transactions cannot be modified and that new transactions can always be added.

All of this poses enormous challenges, such as how to scale the technology to billions of users; how to ensure that data is trustworthy and accurate while still keeping certain details private; and how to maintain high levels of security without using so much computing resources that the cost of electricity becomes a limiting factor for new applications.

“This is a fascinating area of research with deep scientific questions,” said Boneh. “Once you get into the details you quickly realize that this area will generate many PhD theses across all of computer science and beyond.”

The center’s initial five-year research program is being underwritten by gifts from these blockchain organizations: The Ethereum Foundation, Protocol Labs, the Interchain Foundation, OmiseGO, DFINITY Stiftung and PolyChain Capital.

量子链CEO帅初：USDT的高杠杆率是个地雷



昨日量子链CEO帅初分享了一些对区块链的思考，他认为行业的风险包括：

①USDT本质上是20亿美金的USDT支撑了行业3000亿美金的市值，杠杆率100倍以上，USDT的流转速度是法币的10倍，这是一个地雷；
②交易所巨额资金被盗，引起市场巨大恐慌，摧毁脆弱的平衡；
③市值较大的项目出现严重技术bug，造成用户资金可以任意转取或者区块链网络停摆；
④无数垃圾项目通过ICO，募集的主流币种所形成的堰塞湖，随着市场下跌逐一爆破，形成的杠杆做空效应等。
而行业的机遇则包括：
①股份制被token替代，释放的社会生产力；
②相比纳斯达克，流动性更好，更丰富，更多层次的资本市场的建立；
③超主权货币带来的分布式金融服务；
④在信托服务的帮助下，链上资产种类丰富，风险也多层次，带来的交易机会和服务机会；
⑤区块链帮助构建一个更加高效和精确的新经济系统，组织结构和政府机遇等。

Coinbase中期战略：支持以太坊整个ERC-20令牌标准

据CCN消息，Coinbase运营的基于以太坊的分散式应用浏览器和钱包Toshi增加了对以太坊测试网和ERC-20令牌的支持。上周，在整合以太经典(ETC)之后，Coinbase团队告诉用户和投资者，公司的中期战略是最终支持以太坊的整个ERC-20令牌标准，包括首次发行(ICO)令牌和独立的区块链项目。Coinbase总经理兼副总裁Dan Romero表示，在现在的数字货币监管阶段，特别是在美国，整合数字资产是公司最优先考虑的事情，而这些数字资产绝不能归类为证券。







Toshi, the Ethereum-based decentralized application browser and wallet operated by Coinbase, the world’s largest cryptocurrency exchange, brokerage, and wallet platform, has added support for Ethereum testnets and custom ERC-20 tokens.

Coinbase Roadmap
Lsat week, upon the integration of Ethereum Classic (ETC), the Coinbase team told its users and investors that the mid-term strategy of the company is to eventually support the entire ERC-20 token standard of Ethereum, including initial coin offering (ICO) tokens and independent blockchain projects.

The official statement of Coinbase released on June 12, read:

“We have previously announced our intention to support the ERC20 technical standard and Bitcoin forks. We will announce the intention to add specific assets within those categories prior to final engineering integration. This is consistent with our public process for adding new assets.”

Dan Romero, the general manager and vice president of Coinbase, acknowledged that the company’s integration of Ethereum Classic could come across as a surprising decision to the majority of traders. Romero emphasized that at the current phase of cryptocurrency regulation, especially, in the US, it is of utmost priority of the company to integrate digital assets that in no way can be categorized as securities.



ethereum classic investment trust
Coinbase has announced that it will add support for Ethereum Classic.
Recently, the US Securities and Exchange Commission (SEC) officially clarified, for the first time in history, that Bitcoin and Ethereum are not securities. As a hard fork of Ethereum with the same decentralized and transparent characteristics as Ethereum, the clarification of the SEC automatically meant that ETC is also, by definition, not a security.

As CCN previously reported, William Hinman, the Director of Corporate Finance at the SEC, said at the Yahoo Finance All Markets Summit:

“And putting aside the fundraising that accompanied the creation of Ether, based on my understanding of the present state of Ether, the Ethereum network and its decentralized structure, current offers and sales of Ether are not securities transactions. And, as with Bitcoin, applying the disclosure regime of the federal securities laws to current transactions in Ether would seem to add little value.”

The mid-term vision of Coinbase to support the ERC-20 token standard, which includes ICO tokens and Ethereum-based blockchain projects, was validated by the recent announcement of the SEC. The acquisition of Paradex, a decentralized cryptocurrency exchange or relay, and the new features added by Toshi, Coinbase’s native Ethereum app, has demonstrated the confidence of Coinbase of listing tokens.

“We already automatically show you popular ERC20 tokens that you own inside your Toshi wallet. With this latest release, we now we let you add custom ERC20 tokens that are not yet in our database,” the Toshi team said, allowing users and investors to store ERC-20 tokens freely, similar to other platforms such as MetaMask.

Positive Development for Ethereum and Tokens
Coinbase is a well-structured multi-billion dollar conglomerate best known for its experienced executive team that have migrated from the traditional finance sector to the cryptocurrency industry. The confidence shown by Coinbase in integrating tokens and operating Ethereum-based platforms such as Paradex and Toshi will lead to the mainstream adoption and rapid increase in the usage of tokens in the long-term.

The high-tech entrepreneur and venture capitalist will build a home with a swimming pool but has not yet filed for a building permit.

Israeli high-tech entrepreneur Moshe Hogeg, manager of the Singulariteam venture capital fund, recently bought a five-dunam (1.25-acre) lot in the prestigious Kfar Shmaryahu community for $19 million (NIS 70 million), sources inform "Globes."

Hogeg is planning to build a home with a swimming pool on the land but has not yet filed a request for a building permit. Hogeg currently lives in the Park Tzameret neighborhood in Tel Aviv.

In recent years, Hogeg has been involved in many ventures of companies in the cryptocurrency sector. Among other things, he founded the Sirin Labs startup, which develops the Finney smartphone based on blockchain technology.

Sirin completed a $158 million initial coin offering (ICO) in December 2017. This financing round, conducted through a sales of the SRN cryptocurrency, was among the largest cryptocurrency offerings in the world in 2017.

The real estate deal was one of the largest luxury real estate deals last year; the volume of deals in this market in Israel has fallen steeply over the past two year, among other things because of the taxes levied by the government on foreign residents.

Hogeg's office said, "We do not comment on private matters, regardless of whether or not they are correct."

DASH将推出IOS和安卓钱包应用

据DASH官方消息，其核心团队宣布正准备在IOS和安卓上推出DashCopay钱包应用程序。该钱包可设置当地货币、所需的网络费用以增加/减少确认时间。项目分三阶段实施：测试网beta版本、主网beta版本、按地域逐步发布产品。



DASH Coin is one of the most technologically advanced digital assets in the world. The team has remained active and innovative over the years and they are stopping at nothing to make sure that the community has the best platform. A recent research by eToro shows that DASH Coin is extremely undervalued among other cryptocurrencies.

The crypto was incepted in January 2014 and at that time it was referred to as XCoin. Evan Duffield is the founder of Dash and built Dash on Bitcoin protocol but introduced anonymity in the algorithm. Later Dash was rebranded to Darkcoin, but in a bid to be a global payment platform they rebranded again in 2015 to Dash which also means “Digital Cash”

The latest announcement on Twitter notes that the team is preparing the launch of the DashCopay wallet. The wallet application has been designed specifically for the iOS and Android operating systems. The wallet is said to be packing some high level features including the creation and importation of personal wallets, creation of address books, it can set local currency, it can also be used to send invites to friends through email or text, the wallet can create as well as join shared wallets in something called multi-signature. Other features include viewing of history of transactions, sending and receiving of funds by simply scanning a QR code or copy/paste the wallet address, it can set the desired network fees to raise/lower confirmation times and touch ID log in (iOS). While commenting on the challenges faced during the execution of the DashCopay wallet project, the team wrote:

“We faced several challenges in the implementation of this project. However, we made a promise to the community to deliver DashCopay to support the need for multi-signature mobile wallets. The challenges included third-party vendor management as well as underlying architectural issues inherited from the reference Copay wallet. Despite the challenges and delay in delivery, we feel that this product will be of value to many members of the Dash community.”
The team has decided to introduce the phased released process due to the challenges associated with the code especially the adaption. The project will from now onwards be released in phases while working to get rid of any risks as well as give the development team the opportunity to locate and resolve bugs in the software. Before moving to another phase, an evaluation will be carried out to find out if it is safe to move to the next level. The phases have been split into three and they include:

1) Beta version for testnet (30-day test)

2) Beta version for mainnet (30-day test)

3) Production launch with gradual rollout by geographical area

The users have been asked to register to test the beta version and this applies to both iOS and Android operating systems. Besides, they have been asked to help the development team by submitting any issues faced and all feedback on the Dash Forum’s “’Copay Support’ board.” DASH Coin fans and followers reacted with excitement on receiving the news and congratulated the network for their exceptional contribution. One follower by the name ‘ToaOfSatoshi’ said in a comment:

“It’s great to see this project finally come to fruition. From what I’ve seen, the CoPay wallet looks slick. I’m really looking for great things now that the development personnel structure is gelling under @bob Carroll’s leadership.”

马昊伯：平台币在价值虚高之后一定会崩盘

Aelf创始人马昊伯今日凌晨在朋友圈发文称：由于早期平台币供应量稀少，在持有币就能得到分红的情况下，会有大量买盘直接购买平台币，推高价格，但当价格被推高后，购买成本增加，还不如用手续费购买划算。这两种获得平台币的方式在动态博弈，最终推高了平台币价格，产生了大量交易手续费利润用于分红。最终当先入场低成本获取平台币的用户获利出逃时，大量后进入用户接盘。因此平台币（一定是有价值的，但是没那么大，肯定跟三大平台差远了）在价值虚高之后一定会崩盘。

剑桥大学数字货币教授：哪个系开设区块链课程都不会感到意外



据Bitcoin消息，随着加密货币热潮席卷全球，开设数字货币、比特币和区块链课程的高校也越来越多，但从学校内部角度来看，哪个学院或者系开设区块链课程成为讨论的焦点，剑桥大学加密货币教授Garrick Hileman就表示，“无论是计算机、经济学、法律、会计、金融系还是商学院，哪个学院开设区块链课程都不会让我感到意外”。





Can only a law professor teach about smart contracts? Universities have faced several challenges with adding crypto classes to their curriculum such as a scarcity of knowledgeable lecturers and an ecosystem that develops much faster than they can reprint books. Now they also have to worry about different departments bickering over control of the multifaceted subject.

Academic Tug of War Over Crypto Classes

Control of Highly Demanded Crypto Classes May Spark Turf War at UniversitiesBitcoin, cryptocurrency and blockchain classes are all the rage at academic institutions around the world, from Chicago to Brazil and even North Korea. In fact, they are now in such high demand that academics fear they might lead to a turf war between computer science, economics, law, accounting, finance departments and business schools.

Garrick Hileman, who lectured about cryptocurrencies as part of a master of finance course at the University of Cambridge, told the Financial Times that: “It wouldn’t surprise me to see some turf wars break out over who owns the blockchain curriculum at business schools.”



David Yermack, professor of finance at New York University Stern School of Business, started teaching about Bitcoin to MBA students back in 2014. He explains that: “It’s interdisciplinary. The computer science and finance industries have merged and this needs to happen in universities too. But universities are bureaucratic — it will be political and take time.”

Demand From Students, Finance and Tech Companies



Control of Highly Demanded Crypto Classes May Spark Turf War at UniversitiesThe reasons for the strong demand for blockchain courses include of course the great price rally of 2017, but also the new avenues opened up by smart contracts and ICOs. “The increase in value in the cryptos played a large part in the increase in public interest,” explained Jens Martin, a director at University of Amsterdam Business School. “However, we feel that the finance industry is very interested in the technology itself and the possibilities it offers. We see many applications not only from people with a banking background, but a more diverse group who are interested in applying these concepts to finance.”



Robert Wardrop, director of the Cambridge Centre for Alternative Finance at the Judge Business School, said that demand for teaching crypto skills is mainly coming from tech companies such as Amazon, Google and Microsoft. “The core focus of interest is growing from non-financial firms.” These “are essential to related projects that these businesses are working on. Understanding issues like asset tokenisation is quite fundamental . . . in terms of your business model but also to your capital raising,” he added.

美国国会官员：对比特币的监管得保持适度弹性



美国国会区块链核心小组创始人之一、国会管理和预算办公室主任Mick Mulvaney在未来金融科技峰会上表示，“我们在比特币早期发展阶段就知道，与任何发展中的金融技术一样，我们需要找到那个契合点。如果类似Mt. Gox破产的事情成为常态，它将极大地削弱人们对比特币的信心。但是，也不能不要用过于复杂的规章制度来打消人们积极性。”

The U.S. government needs to find the "sweet spot" in its oversight of the cryptocurrency ecosystem, Mick Mulvaney, acting director of the Consumer Financial Protection Bureau, said on Wednesday.

Speaking at the Future of Fintech conference hosted by research and analysis firm CB Insights, Mulvaney, who also heads the Office of Management and Budget, touted his pro-bitcoin credentials, noting that he is fiscally conservative and "was one of the founding members of the bitcoin caucus and blockchain caucus."

Sympathies aside, he argued that regulation is important to protect investors – but the government should not discourage potential investors or developers from entering the market through burdensome laws or regulations.

Mulvaney explained:

"We knew at an early point in bitcoin that as with any developing financial technology we needed to find that sweet spot … if Mt. Gox became a regular occurrence it dramatically undermines confidence in the markets and prevents innovation. And if we over-regulate and discourage people from entering the marketplace, that has bad consequences too."

In other words, Mulvaney said, "we're looking for that Goldilocks [path] in the middle."

He explained the concerns that might arise with a lack of investor protection, saying: "It's a new and innovative technology, it's a nonbanking system, it's whatever. If people still can't get access to their own money, that's a problem. So the law's functioning correctly there."

What Mulvaney is trying to accomplish now, he argued, is ensuring that the application of an existing law doesn't lead to unintended consequences.

"If for some reason we're looking at you and the only way we can look at you is through the lens of the bricks and mortar financial institution, and because we do that it has this perverse or absurd result, that's what we're trying to identify and to prevent," he said.

中钞区块链技术研究院院长张一锋：数字货币交易所开禁短期内不现实



日前，对于数字货币交易所的乱象，中钞区块链技术研究院院长张一锋评价到，现行的数字货币交易所存在诸多问题，资金和资产托管、交易操纵问题、KYC和AML等，均难以满足传统金融体系中防范风险的既定规则和流程的要求，这也是国家宣布不合法的原因之一。在现有问题没有妥当的解决方案之前，让国家来合法承认交易所是困难的。

基于区块链的经济激励模型，无论是叫做代币，还是叫做通证，在严肃的经济理论方面仍处于早期探索阶段。实践中的很多项目，实际上是没法跳出庞氏漩涡的，甚至有些项目，其本质除了以区块链创新之名行规避金融监管之实，没太多实质性的价值。

在2018全球区块链（杭州）高峰论坛上，中钞区块链技术研究院院长张一锋主要谈到对数字货币的四点看法：数字货币是我们从现实经济进入数字经济一个必然的经济内动力；数字货币依然要满足货币的基本属性，价值尺度、交换媒介、支付手段、价值储藏这些基本特征并没有改变；数字货币是主权信用货币；数字货币不会一夜之间颠覆现有的货币形态，它很可能会在长期时间和今天的纸币，和今天电子支付手段长期混用。

从相对价值稳定性和交换媒介等标准来看，比特币、以太币等虚拟货币今天所表现出来的属性仍然是资产，和货币的认知仍有较大差别。希望这些虚拟货币能够不断演变、直至成为数字货币，或者为未来的数字货币提供进阶。

法定数字货币的出现是整个社会经济形态不断往前发展的必然趋势。以互联网和信息化为技术特征的数字经济，近几年在快速成长，在这一个完全数字化的互联网世界里，同样需要货币这样一种基础设施，这是数字世界成长过程必然产生的内在需求。如果法定数字货币缺位，就会出现像比特币、甚至包括支付宝在某种程度上也是在承担这个数字世界的准货币职能，这是时代进程与社会经济发展的自然逻辑延伸。至于法定数字货币是否采用区块链技术，目前还只能先验证，无论区块链技术可行或者不可行，尚不能为时过早的去断定。

针对数字货币的未来发展，中钞区块链研究院院长张一锋就选型、挑战和影响提出三个观点。第一是模型，对法定数字货币的认识，本身就是个摸索的过程；第二是技术，法定数字货币作为互联网背景下的新货币，对于技术的挑战非常高；第三是影响。无论在货币理论，法律体系，还是实际的金融业务，法定数字货币都将带来很多挑战。总体就是在潜在风险的前提下进行创新。

在接受上证报采访时，中钞区块链技术研究院的院长张一锋称，央行的数字货币仍在研发，还没有明确的推出时间表。张一峰强调，比特币和以太币不是数字货币，只有央行发行的法定数字货币才是真正的数字货币。即使发行了法定数字货币，也不会一夜之间颠覆现有的货币形态，它很可能会在长时间内和今天的纸币以及电子支付手段混用。

中钞目前采用了开放许可链的技术路线，在这套模式中，共识节点数量少，所以性能可以相应提高，系统安全性依赖于更广泛的见证节点的数量。中钞希望借助许可链的性能优势，增强区块链在业务落地中的可信度，更快速切合实际地推进区块链在具体领域的应用落地。

美国经济研究所：比特币比以太坊等四种主要数字货币更稳定

据newsbtc消息，美国经济研究所(AIER)年初进行一项研究，采用平均每日价格变动百分比为度量标准，将比特币与主要的数字货币LTC、ETH、XRP、BCH四种数字货币2013年以来的日价格变动进行比较，得出结论比特币比这四种数字货币波动性低，稳定性更强。



American Institute For Economic Research (AIER), an independent 501 economic research institute that does not represent any fund or special interests, has reported that Bitcoin, the most dominant cryptocurrency in the global market, has significantly and consistently been less volatile than other digital assets since 2013.

In early 2018, researchers at AIER conducted a study comparing Bitcoin to major cryptocurrencies and digital assets including Litecoin, Ripple, Ethereum and Bitcoin. AIER found that Bitcoin has been consistently less volatile than the four major cryptocurrencies and discovered an interesting trend in the cryptocurrency market.

Bitcoin’s Volatility

The researchers emphasized that there exists a variety of ways economists measure volatility of a currency or an asset. In its study of cryptocurrencies, AIER researchers utilized a basic method of observing the daily price movement of Bitcoin and other digital assets in the global cryptocurrency market.

“Economists and statisticians measure a variable’s volatility in many ways. We choose a relatively simple metric: the average daily percentage change in price. We average the absolute value of daily percentage returns for each cryptocurrency and year,” AIER researchers explained.

After comparing the daily price movement of Bitcoin (BTC), Litecoin (LTC), Ripple (XRP), and Bitcoin Cash (BCH) since 2013, AIER formed a database of averaged daily price movement of every cryptocurrency over the past five years. Given that bitcoin Cash debuted in late 2017, the price movement of BCH since September of last year was included in the analysis.



Comparison of major cryptocurrencies and their volatility rates, chart provided by AIER
From 2013 until 2018, Bitcoin has managed to demonstrate the lowest volatility rate amongst the four major cryptocurrencies, which have also been less volatile in comparison to small market cap assets and tokens.

“By our measure, in every year, Bitcoin is the least volatile of the five cryptocurrencies we study (we also looked at coefficients of variation, a more technical measure, which yielded similar results). Bitcoin reached its lowest average daily price movement, less than 2 percent, in 2016, before rising again to levels not seen since 2013,” AIER researchers noted.

Hence, the claims of most cryptocurrency analysts that the market valuation of the majority of initial coin offering (ICO) tokens and small blockchain projects is largely influenced by Bitcoin and Ethereum are correct to a certain extent, given that BTC and ETH have shown the lowest level of volatility and highest level of stability amongst all cryptocurrencies in the market.

Still Long Way to go to Compete Against Reserve Currencies

Government-backed fiat money or reserve currencies such as the euro, Japanese yen, British pound, and the US dollar had never recorded a daily price movement of over 10 percent. In contrast, Bitcoin recorded nearly 20 days per year with price changes of more than 10 percent, while Litecoin, Ripple, and Ethereum recorded 30 to 50 days.

“None of the benchmark assets — euro, yen, pound, or gold — had a single day since 2013 with a change in USD exchange rate greater than 10 percent (the largest single-day change was an 8 percent drop in the pound against the dollar after the Brexit vote),” said the researchers.

日本监管机构发出这个命令后 比特币“猝死”(图)

京港台：2018-6-23 10:06| 来源：汇通网 | 评论( 1 )条  | 我来说几句       



　　周五，日本金融监管机构下令数家加密货币交易所整改反洗钱措施，导致比特币价格跌幅达11%。

　　根据CoinDesk的数据，比特币一度跌破6000美元，这是自去年11月13日以来的最低水平。

　　



　　日本金融服务局（FSA）的这一命令导致日本最大的数字货币交易所bitFlyer 暂停了新账户的开立，同时进行整改，特别是在其反洗钱和控制恐怖分子资金来源方面。


　　在发现交易所对反洗钱的控制存在多方面的不足之后，该机构也向其他五家交易所发出了同样的命令。

　　BKCM创始人兼CEO布赖恩·凯利表示：“从长远来看，这会建立了一个更好的生态系统，并确保数字资产的合法化。”

　　凯利指出，在短期内，这将减少比特币最大交易市场上最大交易所的新进资金流入。根据市场分析网站CryptoCompare的数据，日元兑比特币交易占到所有数字货币日交易量的60%以上。

　　比特币周五的走势

　　



　　技术分析师兼牛顿顾问的创始人牛顿说，即便是再轻微而隐秘的新闻也有可能引发大规模的抛售。

　　牛顿还表示，比特币可能还会有两到三个星期的抛售期，在找到底部之前可能会回落到5000美元。

　　2018年，比特币价格因缺乏新买家而受到影响，继去年12月升至近2万美元之后，比特币价格今年来下跌了一半以上。根据CoinMarketCap.com的数据，数字货币的全部市值自1月份以来，已经下跌了大约50%。

　　中国是第一个采用国家制度来监管数字货币交易的国家，日本的监管机构也同样是数字货币监管的先锋。

　　今年3月，日本监管机构向多家交易所发出处罚通知，并迫使一些交易所在“5.3亿美元被盗事件”后完全停业。

　　分析师指出，近期，比特币交易所频频倒闭，可能是令比特币持续下挫的另一个重要因素。6月20日，86bex正式宣称，由于所自上线以来持续亏损，以及投资人的撤资，将关闭提币通道。

　　无独有偶，一周前，正式上线不到一周的Cattleex交易所也宣布了破产，Cattleex表示，由于投资人的撤资以及所无法满足绝大部分的矿工的拉盘要求，纷纷砸盘提现，导致所已无法正常经营。

　　另外，韩国(专题)Bithumb交易所曾发公告称，因安全问题日益严重，临时全面停止所的充值和提币业务。

　　交易所需要具备的技术资源、运营管理人员、口碑品牌以及社群等，小交易所都是不具备的，所以大批的交易所倒闭在预料之中。

　　周五，其他加密货币与比特币一齐应声下跌。按市值计算第二大加密货币ETH下跌了9%，而XRP则下跌了大约7%。比特币现金和莱特币约下挫11%。

腾讯区块链技术总经理：杀手级区块链应用面临海量存储难题



据人民网消息，腾讯集团区块链技术总经理李茂材今日在会上表示，未来真正杀手级区块链应用问世后，普遍将面临海量存储如何解决的难题，希望与同行一起参与，进行更多的探索。在李茂材看来，现在区块链行业存在炒概念现象。面对大有可为的区块链，企业必须练好内功，真真切切深入到行业，结合具体业务问题，把细节做清楚，把工作做到实处。李茂材指出，区块链是通用型技术，不应该只停留在炒币与技术讨论层面，可以深入更多行业实际问题，融合云计算、大数据、AI等技术探索创新解决方案，或许能创造出更大的想象空间。李茂材透露，目前腾讯区块链已经在数字发票、智慧医疗、游戏等多个领域有落地。

在2018年全球链界科技发展大会上，腾讯区块链技术总经理李茂材介绍了目前腾讯公司在区块链技术上的应用实践。1、游戏：以玩家的虚拟资产应用为主；2、海量存储解决方案：分为用户数据存储方案和块链文件存储方案；3、税务：以基于区块链的电子发票应用为主，使用密码学信息学机制和探索数据半隔离机制。

目前，腾讯区块链已经在供应链金融、医疗、数字资产、物流信息、法务存证、公益寻人等领域实现落地应用。区块链历经多年发展，无论在技术层面还是在应用层面都有非常多的创新，但在探索商业应用的过程中，工程上还面临着不少挑战，整体还处于早期阶段。
