V神:数字货币是人类彼此互动的新选择



[yt]eSPaNVYEWn8[/yt]

VICE中国发布采访V神视频,根据V神的回答,他大概在2011年2月第一次听说比特币,有人出价5个BTC写比特币博客文章,当时比特币价格0.8美元。之后,他用自己写文章赚来的比特币买了T恤。真正让他醍醐灌顶的是,他看到人们居然是可以一起创造一个新的金融体系,让他深受鼓舞的并不是要把所有的东西都抛弃,它更像一个理念。
在之前,金融等很多东西感觉就只能“上层人士”作,没了他们任何事情都不可能发生。而现在,金钱是一种一个群体能自主创造使用的东西。其实很早就有各种文件分享系统、去中心化通信系统,有一群网络极客竟然能用去中心化方式做这些事,这代表着一种划时代的变化,一种人类彼此互动的新选择。有了比特币你就不再需要钱和银行了,都是直接点对点的操作,以太坊将其扩展成为数字智能合约的平台,它确实有颠覆的潜力。

V神:数字货币是人类彼此互动的新选择



2018-01-19金融

19岁创立以太坊,币圈资本浮躁中坚挺的一股清流

虚拟货币这把火从2017年烧到2018年。然而2018一开年,虚拟货币的日子不太好过。

先是比特币跳水,震荡下跌,一度跌破10000美元。




紧接着以太币在一天内大幅贬值,幅度之大,令人心惊肉跳。

看好虚拟货币的投资人坚信入场的机会来了,Diss虚拟货币的人高呼这个“巨大无比”的泡沫终于要破裂了!

不管你是支持派还是Diss派,不管虚拟货币的未来走势怎样,虚拟货币已经成为每个人无法回避的话题。

认识虚拟货币,我们需要从它的源头开始了解,硅兔君(ID:sv_race)今天要为大家介绍以太坊创始人,90后小哥Vitalik Buterin,江湖人称“V神”。



V神的长相是不是与马云爸爸有一拼?

2013年年末,19岁的Vitalik Buterin给他的好友们发了一份白皮书,建议设计一种新的比特币。这款新的比特币将基于通用的编程语言,可以用来创建各种各样的应用,比如社交、交易、游戏……

Buterin发给了15个人,这15个人又相继发给了他们的好友。一传十,十传百,Buterin的想法很快就在比特币社区里炸开了锅。



Buterin本以为自己的想法还存在不少漏洞,谁想到竟然受到了一致好评。不少人竟为了这个前卫的想法兴奋到不能自已,亲自找上门希望和Buterin一起合作。

彼时的Buterin,刚刚获得10万美元Thiel奖学金(Paypal创始人、硅谷投资大佬Peter Thiel为鼓励20岁以下年轻人创业的奖学金)。这笔钱还没有焐热,就被Buterin用来开发一个去中心化、基于区块链技术的计算平台,取名以太坊(Etherum)。




同时,Buterin还为以太坊设计了一种新的加密货币币种—以太币(Ether)。2015年,以太坊正式上线。



两年间,以太坊的出现激活了区块链背后的巨大潜力:以太币的价格在2017全年翻了85倍;由以太坊奠基的ICO在2017年成为最火的资金众筹方式,全球通过ICO募集了超过40亿美元;2017年,全球电子货币的市场总值从年初的180亿美元暴涨到5600亿美元。

如果说中本聪(比特币创始人)是区块链的创世者,那么如今24岁的Buterin则是一手将区块链推上了浪潮之巅。为此,Buterin还获得了一个昵称:V神。

和世界格格不入的外星人
Buterin 1994年出生俄罗斯,1999年随父亲移民加拿大。

翻开Buterin的童年故事,和历史上所有的天才少年一样:天赋异禀、才思高人一等。

有关Buterin的轶事有很多:

比如他7岁的时候创建了一个叫做”兔子百科全书“的复杂文档,这是一个由兔子组成的小世界,但世界里的规则符合非常严格的公式,里面全是数学,图表和计算;



他心算三位数的速度是同龄人两倍多;

他花了几个月时间可以流利地说中文;

他看上去也特别符合一个怪才:瘦如竹竿,顶着个巨头,语速极快,经常眼神飘忽不定,有人说他自闭,更多人愿意称他为“和世界格格不入的外星人”。



连Buterin自己都说,“为什么我不能像一些普通人一样拥有75%的平均水平。”

17岁那年,Buterin开始接触刚刚2岁的比特币。这大半要归功于他的父亲Dmitry Buterin,他是一家区块链孵化器Blockgeeks Labs的联合创始人。



起初,Buterin并没有很看得上比特币;但慢慢地,他被区块链技术的去中心化属性给深深地吸引了。

什么是去中心化?Github是一个很好的例子。Github就是让所有人在互联网上分享和贡献代码,在Github里,没有所谓的中心化公司,所有的交互都是人与人之间产生。



试想,在区块链的世界里,所有事物都是去中心化的:从一个应用,到一家公司,都必须通过每个人来贡献,大家遵守共同制定的规则。这个想法,深深地吸引了Buterin。从小受动画文化影响的Buterin,向来厌恶扮演反面角色的大政府和大财团。

于是,他走上了和很多天才一样的道路——辍学。当时刚刚进入加拿大滑铁卢大学的Buterin满脑子都是比特币。他唯一的想法是出去走走,和全世界的区块链爱好者交流和互相学习。



这个想法受到了他父亲的反对,同样是程序猿的Dmitry希望儿子毕业之后可以进入苹果或者谷歌。好在,父亲算得开明,他也看透了儿子不安分的本质,Dmitry对Buterin说,“辍学后的人生会更加充满挑战性,但你也会学到很多。”

2013年,Buterin从滑铁卢辍学,并开始周游世界,在阿姆斯特丹、旧金山、以色列等城市开始游学。

游学的同时,他还开始撰写有关比特币的刊文,一篇稿费五个比特币(放到今天就是一篇60,000美元……噢不对57,000美元……又不对……)。



在当时,五个比特币仅价值3.5美元,但即便如此,Buterin却乐在其中。之后,这份兼职因为网站关闭而停止,Buterin就决定自己创立一家媒体,名为比特币杂志(Bitcoin Magazine)。这份杂志之后被BTC Media所收购。

一手打造以太坊
2013年年末,游学归来后的Buterin有了些新想法。

当时的比特币爱好者正在全力以赴地为比特币增加更多的功能性,打造比特币2.0。但Buterin认为,建立一个全新的编程语言才是比特币的当务之急。出于安全原因,比特币的开山鼻祖中本村用了一种复杂的脚本语言编写了比特币协议,然而这种语言有意地限制了交易的复杂性,也导致了比特币一直没有开枝散叶,孵化出更多的应用。

比特币协议自然是不能重写了,可如果是用一种通用的脚本语言,打造一款新的计算平台和新的加密货币呢?Buterin很快写下了一篇白皮书,并在文中介绍了以太坊。



如前面所言,这份白皮书迅速在比特币社区里流传,并“出乎意料”地受到了同行们的认可。Buterin自己都没有想到以太坊会如此受欢迎。信心大增的Buterin,在2014年年初联合几位合伙人开始动手。他们通过ICO的方式来为新的加密货币以太币募集资金。以太本就是一种在科学理论下还未证实的物质,这也暗含了Buterin对以太的期待。

和其他的加密货币一样,Buterin决定用ICO的方式进行众筹,用户可以用比特币来预购以太币。以太币的定价是2000个以太币=1个比特币,按照当时每个比特币600美元的价格,一个以太币是0.3美元。

最终,这次ICO一共募集了31,000个比特币,即1,800万美元,这让它成为了加密货币历史上价值第二高的ICO。 有了这笔钱,Buterin的团队很快在瑞士成立一家非盈利公司Ethereum Foundation。



2015年6月,第一款以太坊发布,取名Frontier。所有承诺给早期投资者的以太币被顺利地交付,开发者们也开始在以太坊上编织他们的梦想。

一场以太坊的去中心化革命就此到来。

没有什么不能被“以太坊”
2017年11月末,一款叫做CryptoKitties的养猫游戏正式上线。



云端吸猫本是这几年无猫人士的网络新宠,但CryptoKitties则基于以太坊平台打造,所以又被称为链养猫。

简单说,CryptoKitties就是一款通过以太币进行交易的饲养游戏,玩法和Pokemon类似,玩家可以养猫、生猫、卖猫,品种越稀奇、年代越久远、特征越古怪,越值钱。



这款游戏疯狂到什么地步?

截止去年12月初,最贵的一只猫以140个以太币(价值11万美元)成交,游戏交易金额突破600万美元,交易量占据以太坊20%。



为什么人们钟爱CryptoKitties?因为猫可爱、养猫的过程有趣,但最最重要的是玩家们开始尝到了链养猫的好处:我养的猫,谁也偷不掉。

除此之外,人们看到了以太币的增值潜力。

在CryptoKitties上线前的12个月,以太币已经疯长了超过8000%。换句话说,你养一只猫,什么都不做,它都有可能增值。

CryptoKitties或许是以太坊历史上最为成功的应用,但绝不是唯一。从2015年上线至今,以太坊已经孵化出了各种各样的应用,比如:

Augur,基于以太坊的市场预测软件;



Ujo,允许用户从艺术家手上购买音乐,并按比例向乐队成员发放;



Transactive Grid,一个可以直接销售可再生能源的应用。



这些应用,都看重了以太坊的去中心化特质,直接在用户和内容创作者或者提供者之间搭起桥梁。而这些成果,都是Buterin乐于看到的,一个基于以太坊的应用生态正在被慢慢搭建。

一切似乎都按照Buterin的想法进行,直到……

一场黑客攻击,两个以太坊
以太坊有一个重要的功能,叫做智能合约。

你可以将智能合约理解成一个数字化的、全透明的、去中心化的合约中介,帮助用户在以太坊上完成金钱,财产,股权或者任何有价值东西的交易。



智能合约在其他加密货币中也可以被使用,但在以太坊里,智能合约的通用性和可塑性最高,用户想编写什么合约就编写什么合约。但随之而来的,以太坊的智能合约存在着许多安全隐患。

2016年5月,以太坊的去中心化组织The DAO(Discentralized Autonomous Organization)完成了1.5亿美元的众筹。The DAO是一家以太坊的风险投资机构,通过智能合约的方式,投资以太坊内的初创和项目。The DAO的特点是不受任何组织控制,所有持有DAO代币的成员投票决定是否投资以太坊的应用。



这笔众筹迅速地吸引了大众的瞩目,也包括了黑客。这些黑客们发现了The DAO智能合约中的代码错误,这些错误所引发的安全漏洞就好比你去ATM机随便拿几百万美元那样严重。

2016年6月18日,The DAO遭受匿名的黑客攻击,价值5000万美元的以太币不翼而飞,这也成为了史上最大的一次数字劫案。一下子,所有的以太币持有者恐慌了。以太币从20美元一下子跌到10美元,市值蒸发5亿美元。



说好的安全呢?说好的万无一失呢?

被推在风口浪尖的Buterin做出了一个大胆的决定——更新以太坊区块链,修正The DAO。

这个举动一下子引起了许多人的不满。无论是比特币还是以太币,创立伊始,都不允许更改和恢复,许多人认为此举违反了区块链创立的初衷。

由于是以太坊的去中心化,Buterin的决定必须通过大部分用户的认可。结果,以太坊分成了两派,一派是经典以太坊(Etherum Classic),他们坚持区块链不容更改的初衷,留下来继续维护原有的以太坊;另一派则还是以太坊,有Buterin带队,他们更新了以太坊的许多安全漏洞。这一次分裂也被称为硬分叉。



好在,这一次分叉的结局是以太坊安稳度过危机——失去的5000多万美元被追回;无论是经典以太坊还是以太坊本身都继续得以发展。而市值跌到5美元的以太币,则在一年半之后暴涨到700美元。

但即使以太坊发展的这么好,Buterin却开心不起来。如今的以太坊似乎没有按照Buterin的设想在正确的方向上发展。

就在最近,Buterin连发几条推特,告诫所有以太坊的用户成熟起来。他不希望以太币沦为人们投机生财的“郁金香”。



Buterin甚至还威胁道,“如果你们再这样的不成熟,我就将退出以太坊。



Buterin不希望以太坊只是一场狂欢之下的投资泡沫,而是能够渗透进所有的工业中,将全世界的经济、社交、文化都去中心化。这一年,Buterin东奔西走,在美国、俄罗斯、加拿大、亚洲等国家普及以太坊知识,以期帮助人们形成对以太坊的正确认识。虽然资本、区块链和以太坊走进了公众视野中,但离Buterin想要实现的远大目标还有很长一段路要走。



童年,Buterin就意识到自己与其他人不同,承担的使命也应该与众不同。在他眼里,天才有天才应该做的事情,V神的万里长征才刚刚开始。

安全专家认为数字货币将作为主流资产存在

绝大多数网络安全专业人士认为,数字货币将成为金融领域的永久性固定资产,甚至可以作为法定货币的既定替代品。这是根据调查网络恶意软件保护提供商Lastline在200多名随机选择的参加2018年旧金山RSA会议的IT安全专业人员中进行的。受访者中有84%的人认为数字货币将一直存在,成为传统货币(45.2%)或周边产品(38.9%)的主流替代品。约14.5%的人表示他们愿意以数字货币的方式获得他们的工资,而不是用法定货币。

Survey Finds Security Professionals Believe Cryptocurrencies are Here to Stay, But Are Not Convinced They Pose a Threat to Enterprises
Data gathered at 2018 RSA Conference reveals security professionals' perspectives on the future of cryptocurrency, ransomware, and IoT


REDWOOD CITY, Calif., May 24, 2018 /PRNewswire/ -- Lastline®, the leader in advanced network-based malware protection, today announced the results of its survey conducted at the 2018 RSA Conference in San Francisco. Reflecting input from more than 200 randomly selected IT security professionals, the results showcase their perspective on the future of cryptocurrencies and cryptomining, response to ransomware attacks, and security impact of IoT devices.

"Security teams are fighting a multi-front battle to keep their organizations safe from cybercriminals," commented Dr. Giovanni Vigna, Lastline Co-founder and CTO. "The threats range from established attacks, such as ransomware, to newer challenges such as those introduced by web-connected devices and cryptocurrencies. We have always used input from security analysts to inform our product capabilities and roadmap, and surveys such as this one provide us with valuable insight into what's front of mind for security professionals."

Cryptocurrencies and Cryptomining
The survey found that 84 percent of security professionals believe cryptocurrencies are here to stay – either as a mainstream alternative to conventional currencies (45.2 percent) or a fringe option (38.9 percent). Enough believe in this new type of money that 14.5 percent would rather collect their salary in cryptocurrency than in a traditional currency.

However, the survey also found that that 7 in 10 professionals don't see a resulting threat to their organizations, even though it's well documented that criminals are launching attacks that turn enterprise devices into miners on their behalf (see CryptoJacking, CryptoMining, and the Rise of Monero). While 35.6 percent agree that cryptomining is possibly a threat, they also think it's unlikely, while another 22.6 percent say it is not a threat, and 12.5 percent say it's too early to tell. Only 29.3 percent recognize that it's a clear and present danger, which is particularly interesting in light of the large majority that believe cryptocurrencies are not just a passing fad. And where there's money, there are criminals.

If the nearly half who believe it will go mainstream are correct, then it's likely that criminals will find new ways to exploit cryptocurrencies, increasing the risk in the eyes of security professionals as the attack surface expands.

Ransomware
While 9 in 10 security professionals have stepped up their organizations' game to some degree, nearly half (44.4 percent) admit to not having done enough to protect against the next WannaCry-scale attack. At the same time, an overwhelming 81.2 percent believe that ransomware attacks against enterprises will increase. This should be a red flag, considering how many organizations have not done enough to improve their defenses.

Chatbots and IoT
Basically, all security professionals (99 percent) believe that the Amazon Echo and other chatbot devices pose a security risk to the enterprise, while a majority (62.1 percent) believes they should be banned from work environments. It's good to see the overwhelming consensus that these web-enabled devices pose a security risk, and considering that it's unrealistic to believe that banning these devices will mitigate the risk, it's important to figure out how to secure them given that the quantity and variety will certainly increase.

When asked to name the two threat vectors that pose the largest risk to enterprise network security, email topped the list, mentioned by 44.8 percent of security professionals. And given the results regarding chatbot devices, it should come as little surprise that IoT devices were a close second (44.3 percent). However, all attack vectors offered in the survey received a substantial number of mentions (mobile = 39.4 percent, social media = 31.0 percent; cloud = 29.1 percent, and Web = 16.7 percent), emphasizing that all attack vectors pose significant risk, and security teams need strategies in place to protect them all.

捷克公用事业公司推出加密支付

据bitcoin消息,捷克最大的能源供应商之一PražskáPlynárenská最近宣布计划开始接受客户的加密货币。其管理层表示,比特币支付选项应该在下个月提供。该公司即将加入越来越多的捷克企业,通过将其引入到能源领域来处理加密支付。

Czech Utility Company Introduces Crypto Payments
One of the largest energy suppliers in the Czech Republic has recently announced plans to start accepting cryptocurrency from its customers. The bitcoin payment option should be available as early as next month, its management said. The company is about to join a growing number of Czech businesses processing crypto payments by introducing them to the energy sector.

Reaching Out to the Young People
The firm in question, Pražská Plynárenská, is not new to the concept of diversification. It is one of the major suppliers of natural gas in the Czech Republic, serving 420,000 homes and businesses. The company is also an electric and heating utility which installs photovoltaics and gas-operated boilers, its website shows. According to its Bloomberg overview, Pražská Plynárenská is engaged in assembling and maintaining telecommunications equipment, servicing motor vehicles, and many more business endeavors, including IT services. The latest project – bitcoin payments.

Czech Utility Company Introduces Crypto Payments

“In June, we are opening a payment gateway, which will automatically transfer our bitcoin payments into regular currency, so that we don’t have to speculate with cryptocurrency. But if anyone wants to pay in an alternative way, we want to allow them to do that,” said Pavel Janeček, chief executive officer of the Prague-based company. According to Hospodářské Noviny, Pražská Plynárenská will pioneer cryptocurrency payments in the country’s energy sector.

Janeček also said that the introduction of bitcoin (BTC) as a payment option will make his company more attractive for the younger generation. This is obviously a priority as the management has also organized rentals of cars running on eco-friendly CNG especially for Youtube vloggers. “We are trying to reach out to the young customers,” he reiterated, those who buy everything with their mobile phones.

Crypto Payments on the Rise in the Czech Republic
A growing number of Czech businesses are turning to cryptocurrencies as an alternative and modern payment option. Although for some companies this might be merely a marketing move, with few of their customers paying in crypto and the merchants immediately converting the coins to fiat, others are more serious about cryptocurrency.

Last year, the largest online retailer in the country, Alza.cz, started accepting bitcoin (BTC) on its platform, as news.Bitcoin.com reported. According to Jan Sadílek, head of internet marketing at Alza.cz, the number of orders and the crypto turnover have increased significantly over the past months. Customers are paying with cryptocurrency for a variety of products, including the popular hard wallet Trezor offered by the Czech-based Satoshilabs. Since February this year, Alza also accepts litecoin, praised for faster transactions and lower fees.

Other examples include several Subway stores and the Paralelní Polis café in Prague, which is popular among members of the Czech crypto community. According to the local press, it is actually accepting only cryptocurrency for your coffee.

Czech Utility Company Introduces Crypto Payments

On the other hand, several banks have been trying to block crypto-related transactions of Czech businesses. One of them, Mbank, has explained its restrictive policies with an argument often used by traditional financial institutions around the world – money laundering concerns. Others, like Komerční bank, have imposed strict controls on operations associated with cryptocurrency. Raiffeisenbank has alerted its clients that transactions with cryptocurrencies like bitcoin are unsafe.

However, a survey conducted earlier this year indicated that the popularity of digital coins is growing in the Czech Republic now, when the fiat koruna is free-floating again. Czechs are more inclined to store value in cryptocurrency than in euros, according to the February Ipsos poll among 525 people. When asked about their intentions to acquire foreign cash, twice as many respondents said they were interested in buying bitcoin rather than acquiring US dollars.

小型银行选择拥抱加密货币市场

对于大多数华尔街银行来说,比特币是一个挥之不去的诅咒。然而对美国的小银行来说,加密货币市场可能是名副其实的“印钞机”。尽管该行业存在监管的缺失和政策的不确定性,但美国的一些小银行仍蜂拥而入,紧跟着加密货币潮流,迅速大捞一笔。华尔街大银行中只有一小部分敢在加密货币领域试水,大部分避之唯恐不及。这恰恰为小规模银行的入场让道,像Silvergate、Cross River Bank和Metropolitan Bank这样的银行都在为客户提供优质的加密货币相关的银行解决方案。
据《华尔街日报》报道,美国Silvergate银行的资产总额从9.78亿美元增长到19亿美元以上,主要是缘于对250多家加密货币公司的业务支持。
不仅仅在美国,欧洲也是如此。在各大银行仍对比特币和加密货币市场持批评态度的同时,瑞士私人银行Falcon和Vontobel、德国的Fidor、列支敦士登Frick等小型银行都选择拥抱加密货币市场。



Small Banks’ New Money Maker: Bitcoin
Most big banks are avoiding cryptocurrencies. To a few small lenders, that means more business for them
By Christina Rexrode
May 22, 2018 10:00 a.m. ET
11 COMMENTS
To many banks, bitcoin and other digital currencies are a mania, or worse. But to a handful of small lenders, they are a moneymaker.

Take Silvergate Bank, a three-branch lender that until recently focused mostly on local businesses in the San Diego area. Last year, its assets nearly doubled to $1.9 billion from $978 million, largely because of business flowing in from crypto-related companies.

Big banks’ decision to largely shun the crypto world has left an opening for smaller lenders such as Silvergate, Metropolitan Bank Holding Corp. in New York and Cross River Bank in Fort Lee, N.J. In part their decision reflects an environment where community banks often struggle to differentiate themselves, given larger firms often can offer consumers and businesses largely unmatchable conveniences with their geographic reach and deployment of mobile and other technology.

As bitcoin has emerged from the underground world of nerds and criminals to become a mainstream investment, the risk of hacks and scandals has also blossomed. What's a government to do? The WSJ's Steven Russolillo travels the world (sort of) to see how regulators are responding to the remarkable rise of cryptocurrencies.

These banks are taking a calculated risk to embrace an untested new market that is associated with a variety of hazards, itself a striking stance in the staid world of banking. Virtual currencies remain unpredictable, defined by wild price swings, increasing regulatory scrutiny and a relative lack of transparency that banks in a postcrisis world tend to shun.

“They’re taking on a risk, and going against the inherent view (of crypto) that ‘It’s all evil over there, don’t touch that stuff,’” said Brian Stoeckert, a partner at consulting firm Stratis Advisory, which specializes in crypto businesses. “But then there’s also a view of, ‘OK, well, they’ve got to get banked somewhere.’”

So far, the Main Street banks have landed customers that are well-known in the crypto world, including the exchanges Coinbase, BitFlyer and Kraken, which allow users to buy and sell digital currency.

Many Wall Street banks, meanwhile, are resisting the idea of trading crypto. Others have restricted customers from using credit cards to buy digital currency. Bitcoin has dropped by more than half since its December record high.



‘Banking in this ecosystem is not for the faint of heart.’

—Silvergate CEO Alan Lane
“Banking in this ecosystem,” said Silvergate Chief Executive Alan Lane, “is not for the faint of heart.”

Mr. Lane, 56 years old, said he became interested in cryptocurrencies several years ago, after reading some predictions about how they would replace the need for banks. Along the way, he learned about crypto exchanges and related companies that, despite a proposition that is largely anti-bank, still need bankers. Silvergate, which is privately held, said it now banks about 250 crypto companies.

Mr. Lane said he isn’t conflicted about being a banker to crypto businesses. “At what point as a banker do you pull your head out of the sand?” he said. “Every banker should be learning about the technology.”

The business can take several forms. Exchanges that let customers buy and sell virtual currency need a place to store their customers’ money and a way for them to convert crypto to dollars. Other crypto companies call banks for help with normal expenses like rent and payroll.

Silvergate says it has also lured hedge funds, family offices and other institutional investors that want to invest in crypto but can’t get their primary bank, such as Bank of America Corp. or JPMorgan Chase & Co., to execute those transactions. The two banks declined to comment.

Genesis Global Trading Inc., a digital currency trading firm, has been banking with Silvergate for several years. Genesis Global CEO Michael Moro acknowledges that a bigger bank would have some advantages. But he said he appreciated Silvergate’s openness to the crypto world, especially after watching other crypto companies go out of business after losing their bank relationships.

“I sat down with Alan early on and he cared about bitcoin,” Mr. Moro said. “He really believed in the potential of what this might become, and honestly it sort of was a refreshing take given the sentiments expressed by some of the other banks, especially the biggest ones.”

Mark DeFazio, CEO of the six-branch Metropolitan Bank, said that doing business for digital companies has allowed his company to increase fee income, which more than tripled in 2017, largely from crypto transactions. The bank has also been able to build up deposits without racking up interest expenses or installing lots of costly new locations, which are often the tactics employed by small banks to juice deposits.

“You could just keep building branches, which is a bad strategy,” Mr. DeFazio said. “We noticed a long time ago that the payments world was changing.”

The regulatory framework for cryptocurrencies, and for how banks can interact with them, is still uncertain. Silicon Valley Bank, of Santa Clara, Calif., which is known for embracing disruptive technologies, has done business with crypto exchanges but has more recently decided to focus on companies working with blockchain, the technology that enables crypto trading.

“You’re getting some level of guidance from regulators, but there’s not total clarity,” said Jake Moseley, head of the bank’s national fintech practice. “We’re being selective at this stage until we get greater clarity.”

The U.S. Treasury’s Financial Crimes Enforcement Network said that anti-money-laundering laws apply to companies that transmit or issue digital currencies and the banks handling those transactions. The banks that have adopted the crypto strategy say they have kept banking regulators well-informed and have rejected clients that don’t meet their standards.

“I don’t look down on anybody who looks at this and says, ‘Gosh, it’s risky,’” said Mr. Lane, the Silvergate CEO. “We’re just very blessed that we have a culture here where we took an interest early.”

工信部李鸣:80%的人只关注数字货币价格,不关注区块链



近日,工信部电子标准院区块链研究室主任李鸣表示:让更多人认识到区块链真正的作用和价值,这个很关键。因为现在区块链很热,大家很关注区块链,其实这个是一个误区,我觉得现在80%的人关注的不是区块链,关注的是区块链上面的金融属性的应用,那么到底区块链是什么?比如说以太坊的特性是什么,EOS的特性是什么,没有人关心,但是大家都关注今天哪些升值了,哪些跌了,我觉得80%的人是在关注这个东西,所以我们最近的主要工作就是怎么让大家真正的认识到区块链的价值,我们也会把我们的思考放到我们的标准制定,放到我们的产业化活动当中。

比特币早期参与者Jeffrey:大矿池让比特币越来越偏离本质



比特币早期参与者Jeffrey Wernick今日表示:比特币是一种哲学,不仅仅是钱,货币。比特币在最初4-5年是遵循这样的哲学准则。但是挖矿、矿霸、大矿池腐蚀了比特币的设计原则,让比特币越来越偏离本质。比特币的价值在于存储价值,这是挑战我们政府的货币主权的,这也是哈耶克推崇的铸币权归人民大众。但是很多人把存储价值和交换、使用价值混淆。比特币用于支付,是非常糟糕的付款方式,浪费很多资源去确认。

Jeffrey Wernick: If we want to transform things, we have to think about its framework
The Blockchain Festival held by Huobi Pro opened at Gem Center in Ho Chi Minh City, Vietnam on 24, MAY.

Jeffrey Wernick, Entrepreneur, Uber, Airbnb and early Bitcoin investor participates the conference and delivers important speech. He says that if you’re in the business of raising money to do something, you have to learn how to make money, not just raise money.

Following is the full text of Jeffrey Wernick ‘s address.

Jeffrey Wernick:

Hello. I don’t know most people in this room, and I don’t really know your background and I was told I have to speak slowly, which is usually pretty difficult for me, so I will do my best.

First a lot of what you will hear so far is a lot of words, smart contract, scaleability, Blockchain, bitcoin, token, crypto, ICO, and I think a lot of people can tell you the definition of a lot of these terms, but really very few understand the meaning.

I think the weakest thing about so far the ecosystem that is attempting to be developed is most of the people, even many speakers at the program, don’t really know much about what they’re talking about. And it is a very, very sad fact.

One of the things, I know the language people use is Blockchain technology. So we have already been told that the Blockchain technology is not very private, it is not very secure, the smart contracts have limited actions and you can’t scale it. That’s I think if you listen to some of the things said so far, that is pretty much what you have heard.

So why are we all here? Why are we trying to do what we think we will do?

Now, I have seen a lot of people, very smart, they have their Ph.D., I have a couple myself. What people need to do is understand business, not raise money. We know people can raise money, but is anybody doing anything useful with the money they’re raising, and I think basically on the most part most people are doing useless things with the money they have raised.

Since people have already used coins and tokens, I see the script I was given, the words I am not supposed to use that others have used so I guess I can use them myself. I tend to like to say it is a bitcoin or shitcoin. So you can pretty much assume that if it is not bitcoin, it is probably a shitcoin. Some of you I assume, since not everybody here is figuring out how to buy bitcoin, you’re trying to figure out how not to issue a shitcoin or not invest in a shitcoin. Maybe what I will do is give you a little guidance from my perspective and then instead of hearing myself talk and you hearing me talk, maybe I will give you an opportunity of you guys asking questions so I can hear what you want to hear rather than me just talking, you know, stream of consciousness here.

Everybody should read the Satoshi paper and understand it in depth. The second thing is when I see the applications people are building, the people building applications don’t know anything about the market structure that they’re attempting to disrupt. I don’t see anybody doing anything really disruptive at all outside of bitcoin. There is nothing really disruptive going on. Some of these cases, I don’t think any disruptive. So how supposedly wonderful the Internet is, and I think it is a great tool, I love using it, but really what we have seen is if you look at how much wealth has been created because of the technology of the Internet, we have basically seen a period of very economic growth worldwide since we have had this technology. So the question is for a number of us, it has made our lives better. What technology has been good at is concentrating wealth. That’s what it has been most effective at, concentrating wealth. If you look at the statistics, the improvement of the middle class, lower middle class, many parts of developed world with the advances of technology, we have more comfortable lives, but we have had more comfortable lives mostly because we’re borrowing more money and becoming debt slaves in return for enjoying some comforts.

So we have to think why is the economy in such bad shape basically all over the world, and it has to be sustained by very creative policy on the part of central banks all over the world, whether quantitative easing, whether it is capital controls, whether it is with the ACB buying up almost all the corporate debt. Ultimately every market in the world is so fragile that it has to be supported by governments in order to preserve the quality of the financial markets. How will we make a better world? One percent owns about 70 to 75 percent of the net worth of the world in the next 20 years.

When we talk about application of big data, what does that mean? You give a lot of information about yourself and in return other people make money off of it, not you. Other people. So that’s what all these platforms, mega platforms are involved. I express it two ways, either data is labor or we are input to people’s production. Only we’re not compensated. How is it that we can maybe reorganize economic activity in a way that would create not only more wealth but that might distribute it naturally better than we do today.

That comes to where I see the application in Blockchain or the type of thinking driving Blockchain where the solution may not be Blockchain but some of the derivatives we spoke of earlier with people building scaleable platforms.

For some who may not know, Blockchain is old technology. 1976, first Blockchain company, ciphered Blockchaining. So if you think why hasn’t technology been around since 1976, no one has done anything interesting? We have to think about what the limitations are, and I think most people working on the platform don’t understand the limitations of the technology because they view it as technology. So when they look at it, they don’t know that. They just hear trustless, get rid of intermediate reveals and the world will be a better place.

Buzz words sound nice, that seems to be sufficient. And there are enough stupid people writing checks to will fund stupid ideas. So whether it will produce a valuable business, that remains to be seen. So far that has really not been the case, except for bitcoin.

So what is the problem we have, a different frame work for the economy, is what has been the consequences of centralization. The consequences of centralization is that we have concentrated economic power, which not only translated into the economic power but also into the concentrated political power which then reinforces itself. The question is a lot of the outcomes we have in the world have nothing to do with how valuable your input is into the production process and mostly has to do with your bargaining power.

The question is how do we change bargaining power? We change bargaining power by growing organizations that go vertical from horizontal. So how do we grow horizontal to where people have to negotiate with people as peers and one person doesn’t have significant advantage over somebody else.

Also, how do we not have people profit off information asymmetries. When I look at how I think of the ecosystem, I think about it as how do we create structures that have us end up behaving more in cooperation with each other rather than in competition. Most people in life, the things they enjoy most are the things they do that generally have them building consensus with people they enjoy and sharing activities with people they enjoy. That’s our relationship with families and friends. Most of them are peer to peer relationship. The only place we don’t have that is in our job. In order for us to be productive, can we only be in a place where we work in absence of peer to peer relationship? I think that many of you who have worked for a company, you think if your boss didn’t show up, you think your productivity would be improved. Many organizations that are successful it is because people are better at organizing themselves in the absence of somebody instructing them to do. You can’t be productive if people are waiting for instructions from one or two people, because then that creates too many bottlenecks.

So what is the opportunity we have really in us being able to extract more value and have more bargaining power over other agents that we interact with in the world? And that’s really a function of how we think about how we organize our activities.

One of the people that influenced me when I was a student at University of Chicago was Ronald Coast, and I encourage you to read his work, “nature of the firm”. So he asked a question most people didn’t think about, and he said why do firms exist? Most people say they exist so there must be a good reason. So he hypothesized that they mitigate transaction. We organize ourselves in the most efficient way possible, to mitigate the cost associated with organizing ourselves among and between ourselves.

So in a world where contract lawyers are somewhat limited and a lot of regulation where you have to lobby, organizing scale gave you bargaining power. So a lot of how we organize ourselves is a function of getting bargaining power over third parties. If we want to influence government, we need to be big. If we want to get a big deal with the supply chain, we need to be big. If we want to make money off of customer, we need to be big. So we figure out how to be big, not necessarily because that creates more value, but it means of how the pie gets divided, we can take a larger share ourselves.

So ultimately the outcomes we have in how prices are allocated really has a significant amount to do with bargaining power.

That’s all I have left? All right. I went through that. So if we organizes ourselves in a way where now we have to cooperate with ourselves. If we had a world out there where every one of you was a token, a sense in a token that because what is the most important capital? Human capital. Everybody in this room is valuable. If you look at the work done by Gary Becker, if you look at the value of companies and the value of a nation, the value of the nation about two thirds is human capital. If you look at property plant, equipment, those type of tangible assets, they’re only a small percentage of the creation process. The rest is us in the room. The question how do we allocate who gets the benefit of it? Prior to really the beginning of this central banking and hyper, leverage, basically the marketplace was valued decently. But once we found a way to balance it, like in the U.S. for example, the financial sector was about 4 to 6 percent GDP prior to the deregulation that occurred in 77 to 1980. Now it is about 20, 25 percent of GDP. So it just so happens coins dent to that is when saving stopped for the middle class, income stagnated, and a lot of it has been basically redistribution of wealth. Other people are capturing the value of our human capital. How do we recapture that?

We can recapture it in a decentralized world. Right now with the beginning of being able to think about the decentralization, there is a world where we define the currency we want to use and we design the organization that we think is appropriate for the way to interact with each other. So we can have a decentralized world if we do more in bitcoin, among and between ourselves, and also if we do more in organizations where we end up having flat organizations where we end up figuring how to cooperate with each other and we don’t let people predate against us, exploit our information. If you think about it, if you would withhold all of your information from Facebook; their value would be nothing.

If you said I have a platform with this data, and this data I will put on this Blockchain platform, and it doesn’t have access to my data, the data I am keeping myself. I keep control of the data, but what I do is I can give a platform governance over that data. So now you can create a platform where all the people who contribute to Facebook, they get to share in the market cap of Facebook rather than just getting some convenience associated with being able to chat with a few friends while the benefits are significantly concentrated. Almost all of these platforms today, everybody is producing information and the value is the information you are producing. The information is how do you get control of that information where you end up profiting and the person you share with is creating value for you.

If you really want to do something that is transformative, you have to think about why the world is organized the way it is and what would cause it to be different. I think people refer to me as I was an early investor in Uber, and I can tell you my thought process between those two platforms.

My thought process in those businesses and how I got my participation is simple. I went to people, my lawyers, and my lawyers represent a lot of the VCs and I told them once this smart firm came out I understood because I’m trained in economics I understood matching models. Wherever the market is, it gets perverted. So once the government intrudes on the market, then it is poorly allocated. It is not a real market price, it is administered and the government is heavy handed.

In the United States, if you look at the data information, and I will refer just to the United States, and I assume studies would be similar in many other countries, if you took a look at the price index for things that the government has nothing to do with, you see deflation. The only areas we have deflation in the United States is in areas where the government is actively involved in. Health care, education, housing, every sector with a significant government involvement we have inflation. And every sector where the government is minimally involved, we have deflation. Naturally deflation is the natural occurrence in history, and that’s why bitcoin is a natural deflation. It has its right.

Once the matching models came out, I thought which of the durable goods are completely mispriced. So I went to my lawyers with connections and I said two businesses people should do. One is somebody can use now the smart phone and create an app where they can match cars with people who need access, because you can never get a taxi in New York when you need one. And the hack license is very expensive because they put restrictions on how many. So if it is raining, forget getting a taxi. You can only find it when you don’t need it, and when I know you need it you can’t find it. So I went to the company and laid out how you can look at the law and I went to my lawyers and I said this work, speak to your friends, and I came up with the idea about a year and a half before Uber exists. Air BNB, same thing. I knew people who owns real estate could advertise their assets, and they’re consumer durables that are mispriced by the marketplace. I basically went to my lawyer and said these are two things people should do, you can do it all in an app, this is just a matching model, so there is actually no real party in the interim, just providing an app, and therefore it doesn’t violate any rules and here is a legal analysis I did.

And if anybody does this, hopefully they’ll remember that the idea came from me. Because at that point in time I was just too lazy to do it myself. I’m generally too lazy to do things myself. So about a year and a half later, two years later my lawyer called me and said a couple of the firms they spoke to were now going to fund this company called Uber, and air BNB, and they were going to be nice enough to give me an allocation at the early round. So I just got it because somebody remembered that the idea came from me and decided to share it with me. But my whole investing philosophy my whole life has been to figure out why when government gets involved in something, how to affect that. Ultimately if we want to transform things, everything basically is an arbitrage operation. We have to think about it in that framework. It can’t just be keep this nice. We have to understand market structure. There is a big difference between being smart and knowing how to make money. And ultimately if you’re in the business of raising money to do something, you have to learn how to make money, not just raise money. And to make money, because I get pitched a lot of ideas and I can tell you most things I get pitched give me a headache after listening. Because people haven’t really thought through it. I feel bad because I think a lot of people are really trying hard to do something meaningful, they just haven’t made the investment in trying to learn enough yet prior to making the effort they’re trying to make. I’m over my time, I need to shut up now. I didn’t give anybody the opportunity to ask question, sorry.

北斗未来首席科学家:区块链可以解决反洗钱工作痛点

据上证报今日报道,北斗未来大数据集团首席科学家李立中认为,人工智能把相关可疑数据通过机器化处理集中在一起,能够解决手工分析的问题,但解决不了识别精准问题和跨机构数据断流问题。大数据本身也有痛点,不能保证数据的真实性。而区块链的特性正好可以解决以上痛点。据悉,该公司目前申请了区块链技术解决数字货币反洗钱问题的创新底层专利,通过顶层设计为未来数字货币添加识别基因,如果未来可以形成国际标准,将可降低反洗钱的成本、提升反洗钱的效率。

全文摘要:
相比于其他币圈大佬,大空翼就是一个草根大V,他没有资本和人脉开矿场,开交易所,发代币,他只是因为一笔投资坚持了3年不动,就轻易地实现了所有人梦寐以求的财富自由,但他也有自己的梦想,如果他当初只甘心做一个矿工,挖山寨币赚点小钱,或是像许多赌徒一样快进快出,今天的币圈,或许又少了一个传奇故事 .

估计大家都听过“大空翼”这个名字,可是又很少有人真的了解大空翼这个名字为啥在币圈这么流行。

币圈有副扑克牌,里面的黑桃4是号称:“深圳传奇,没有之一的币圈大空翼”。而大空翼之所以出名,是因为10万All in IOTA,任由风声鹤唳,仍岿然不动,最终3年收益超万倍。

大空翼,真名叫杜翼添,名副其实的90后,最早以“大空翼”的身份混迹社区,大空翼是日本漫画《足球小将》里的主人公,自小酷爱足球,而现实生活中,杜也是足球的爱好者,名字的来由或就根源于此。

不久之前,大空翼在接受哈希财经采访的时候透露,自己上小学就做过一些小本生意,向同学借钱将班里同学们看过的老夫子回收过来出租,并雇佣了同学管理。再到大一些,大空翼初中的时候由于寝室离街道近,开了个外卖代接业务,甚至垄断了承接走道另一头班级的外卖业务。大学期间,大一暑假去广州学了甜品,准备在老家空白的市场开干,可是亲爹就是不同意。

2013年,大空翼正在英国念大二,暑假他从英国回老家,读书时在网络上接触到了比特币资讯,并深深迷上了。于是,他筹了几万并付诸行动,他在淘宝上寻找合适的矿机,经过一番研究,最后自己组装了一台矿机,造价2万余元,这算是大空翼最早入币圈的本金;那个时候是烤猫矿机和阿瓦隆矿机的时代,当时靠GPU挖比特币已经没有任何优势了,所以大空翼决定挖一些没人挖的山寨币,比如世界币和羽毛币;经过几个月,大空翼挖到了大量的山寨币,后来他把他们全换成了比特币,大概80个。当时一个比特币价位在4000元人民币左右,就这样,大空翼小赚了一万元。这次小小的成功,使大空翼对数字货币的兴趣更浓了。

2015年,大空翼从一个朋友哪里了解到一个叫IOTA的数字货币在做ICO众筹,发行的IOTA代币每个约0.001人民币,经过对白皮书的仔细研究,他把手上仅有的十万元全部投入了这个项目。(为什么高手都是一把梭哈,想当年吴忌寒也是这样投资比特币的哈。)

最初大空翼只是想赚点钱,对各种币的理解并不深,说是投机炒币绝不为过,但渐渐地,他的观念发生了改变,用他自己的话来说,他开始产生了信仰。渐渐的他觉得社区里有一群牛人,他认为世界顶尖的,最有想法的人才都在社区里,这是一群伟大的人,这群人有着伟大的信仰,他们的信仰和驱动力来自于对“去中心化”狂热的推崇,“他们搞开发完全不冲着钱,市场之所以涨这么多,是对他们的认可,是对技术的认可。”

当时中国参与的人不多,大概也只有
7、8个,但最后拿住的只有两个人:他和Jimmy,IOTA中国社区负责人。IOTA最后一共募集了1300多个比特币,价值约三百万人民币。然后故事就从这里开始了。从15年底到17年6月,IOTA一直很便宜,但自6月ICO热潮开始后,IOTA暴涨,到17年12月初一度涨到约36人民币,相比发行价已经翻了3.6万倍,大空翼手中的10万人民币,也变成了几十个亿。

相比于其他币圈大佬,大空翼就是一个草根大V,他没有资本和人脉开矿场,开交易所,发代币,他只是因为一笔投资坚持了3年不动,就轻易地实现了所有人梦寐以求的财富自由,但他也有自己的梦想,如果他当初只甘心做一个矿工,挖山寨币赚点小钱,或是像许多赌徒一样快进快出,今天的币圈,或许又少了一个传奇故事。翻一翻大空翼的朋友圈,也能看到直到现在,他还是很坚信IOTA的。

参与了IOTA项目后,大空翼也就一直没有理它,只是背后默默的关注。从2015年到2017年6月,IOTA的价格一直没有什么大的起色。IOTA中国QQ群直到2017年5月时还不到300人,但自6月份ICO热潮开始后,IOTA暴涨,到2017年12月的时候一度涨到36元人民币,翻了3.6万倍,一个币圈传奇诞生了,从10万炒到36亿,大空翼一举成名成为了币圈传奇人物。



大空翼曾经也输过,2014年比特币有过一次大跌,他当时的100多万一下子亏到了10多万,他一度非常抑郁,“人就是不知足,当时天天拍大腿,就想着如果早卖就好了。”人就是这样,没买之前怕踏空,涨了之后觉得买少了,跌了又后悔怎么不早点卖掉,这是一个死循环,但核心只有一个:当你赚过一次大钱,享受过一夜暴富的快感,你就再也无法接受“赚得更少”的现实。

但大空翼一早就看透了这一点,他认为“买入、卖出不是考验一个投资者综合素质最好方式,跨越牛熊与非议地耐心持有才是”。

他更是在朋友圈分享说:“投资,最忌讳的是情绪化。不要逆势,管理好自己的情绪,保持客观性,才能持久”。但知易行难,能做到的又有多少呢。

大空翼的例子在币圈毕竟是少数,想要真正的成为投资高手,最重要的还是不断的学习,不仅包括自己的投资技巧和策略,更重要的是心态和远见.

“数字经济之父”唐·塔普斯科特:区块链或能助中国成为率先走向第四次工业革命的政府

5月26日,2018中国国际大数据产业博览会在贵阳开幕。“数字经济之父”、《区块链革命》作者唐·塔普斯科特在演讲中表示:“未来每个人都会有一个主权身份,我们可以自行采集自己的数据、决定以什么方式公开这些数据。政府也有合理的权力获得很多数据,但是我们身为公民也有自己合理合法的权力。世界上哪个政府会率先走向区块链,走向第四次工业革命的政府呢?迪拜说它要走在第一位,中国其实是具有世界上最理想的条件,可以重新革新、加强信用、消除腐败。因为区块链上面是完全透明的,阳光是最好的消毒剂,让我们的体制变成‘裸体’,它必须强身健体。”

分布式账册的技术代表了互联网第二个发展阶段。四十年来,我们由传统的信息机构到现在基于价值的互联网,包括股票、债券、房产、艺术品、文化资产,我们自身的身份,碳排放权,任何有价的资产都可以用区块链来以安全、私密方式进行交易,而无须依托一个中介机构,不需要有大家信赖的中间平台,信用的建立可以单靠程序代码,所以区块链技术可以说是经济体的操作系统,也是一个平台,让我们可以革新企业和公司的模式。”

他还称:我们的区块链研究院正在开展八十项研究项目,这些课题都是关于第四次工业革命的一些战略性议题。我们决定要投资于中国,把区块链研究院的工作带到中国来,后面还会做进一步的公布。


京东物流程岩:区块链在物流领域的发展方向应该是“区块链+人工智能+物联网”

美国最大铁路公司之一诺福克南方公司加入区块链运输联盟(BiTA)

美国最大的铁路公司之一诺福克南方公司(NSC)近日宣布加入区块链运输联盟(BiTA)。BiTA是美国旅游和物流行业协会之一,其主要焦点之一是为在其行业中使用区块链技术制定标准。该联盟成立于2017年8月,目前有超过250家参与公司,包括联邦快递、优步货运和普利司通。

U.S. railway network Norfolk Southern has become the latest industry player to join the Blockchain in Transport Alliance.

One of less than a dozen Class I railroads in North America, Norfolk Southern announced Thursday that it would participate in the consortium's mission of establishing standards for logistics companies using blockchain technology, according to a press release.

The company maintains a number of rail lines across the Eastern Seaboard, in addition to providing coal and intermodal transport services in the region.

BiTA vice president Fred Ehlers said in a statement that the rail line would help with streamlining supply chain processes using blockchain.

The statement was echoed by BiTA president Chris Burruss, who said that more than 250 members of the alliance are working toward creating "common blockchain standards that will define the future of freight movement," according to the release. He added:

"Norfolk Southern brings a level of intermodal and rail expertise to the Alliance that will benefit all members and the industry as a whole as we move toward a common framework. We look forward to engaging with them as we move forward."

The rail line joins companies such as the Berkshire Hathaway-owned BNSF Railway, which joined the alliance earlier this year. Similarly, General Electric's transportation division became a member in March.

南非资管公司Sygnia拟三季度上线数字货币交易所

总部位于开普敦的资产管理公司Sygnia计划在第三季度开设一个数字货币交易所,以应对来自全国各地投资者对数字货币日益增长的兴趣。这家资产管理公司目前管理着145亿美元的资产。

Money manager Sygnia said it intends to start a cryptocurrency exchange in the third quarter of this year to tap growing interest from investors in the country in digital currencies.
To be known as SygniaCoin, the exchange will “offer investors a secure trading and execution platform backed by an international infrastructure, well-designed custody and integration with standard savings products,” the Cape Town-based company said.

Sygnia, which has R181bn under management, also plans a fund that will invest in a range of cryptocurrencies, it said in an six-month trading statement Friday.

Digital currencies such as Bitcoin and Ethereum are becoming increasingly popular, and the South African Reserve Bank has started a financial-technology unit to review its position on private cryptocurrencies and to help draw up policies.

The bank chooses to refer to digital currencies as “cyber-tokens” because they don’t meet the requirements to be classified as money, deputy governor Francois Groepe said in Pretoria on Thursday.

灰度投资公司总经理:要么繁荣要么萧条 比特币没有第三条路可走



[yt]p1G0n6fnuBw[/yt]

据bitcoinist消息,近日,灰度投资公司(Grayscale Investments)总经理Michael Sonnenshein在接受采访时表示:关于比特币生存能力的问题,似乎只有两个结论。无论是支持“ 泡沫 ”论点,还是支持“ 未来货币 ”概念或任何其他立场,都必然导致“繁荣或萧条”两种结论之一。就比特币而言,没有中间立场。而对于比特币的命运如何,Sonnenshein认为,只要技术不断改进,数字货币就有希望,比特币的未来与其在新兴的数字货币格局中保持相关性的能力息息相关。

Bitcoin’s future price has been the subject of enormous speculation everywhere from cocktail parties to the floor of the New York Stock Exchange. Some mega-bulls, like venture capitalist Tim Draper, predict the value will rocket to $250,000 in as little as four years. Skeptics, like Joe Davis, strategy chief at Vanguard Investments, say there’s a “decent probability” it goes to zero.

Is Bitcoin’s fate really all or nothing—go big or go broke?

Michael Sonnenshein, managing director of Grayscale Investments, one of the world’s biggest cryptocurrency asset managers and a sponsor of eight digital currency trusts for investors, thinks so. Sonnenshein dropped by Fortune’s offices to share his outlook on Balancing The Ledger, a new show about the intersection of technology and finance. His view: There is no middle ground.


“As we begin to look at assets like Bitcoin and the unbelievable adversity it’s faced over the last 10 years, every day that Bitcoin doesn’t go away, every day that Bitcoin overcomes a new challenge, for me that makes me feel that Bitcoin will do either one of two things,” Sonnenshein told the show’s cohosts, Fortune senior writers Jen Wieczner and Robert Hackett.

“It will either survive and become all these amazing things that we think it can be, which will cause its price to be a lot higher,” Sonnenshein said. “Or it is possible something else may come along that will displace it and Bitcoin goes to zero. It likely will have a binary outcome.”

Get The Ledger, Fortune’s weekly newsletter on the intersection of finance and tech.

Sonnenshein’s personal view, as a cryptocurrency booster, is obvious, although he declined to provide any of his own price targets. (Sonnenshein’s employer, Grayscale, is a subsidiary of Digital Currency Group, one of the biggest cryptocurrency investors around.)

His reasoning goes like this: If Bitcoin’s developers can continue innovating and improving on the technology, making it more useful and desirable, then its value should rise. This is not a foregone conclusion, by any means. But it’s the foundation for Sonnenshein’s investment thesis.

“You have to think about Bitcoin, again, as an open source protocol,” Sonnenshein said.

“Any other currency that comes along that allows for another feature—another attribute that maybe Bitcoin doesn’t have—as an open source protocol, [Bitcoin] is able to accommodate, to integrate, to add that aspect into it,” Sonnenshein said. “So I hope and continue to believe that as new features are added into Bitcoin and other digital currencies, they can continue to thrive and grow and not be displaced.”


Maybe Bitcoin will become the Internet’s “native currency,” as Twitter and Square CEO Jack Dorsey recently put it. Or maybe the whole thing will blow up in a ball of smoke. Your guess is as good as anyone else’s.

At the moment, Bitcoin’s price has taken a downturn on news that the Department of Justice has opened an investigation into possibly nefarious market manipulation by cryptocurrency traders. But given the cryptocurrency’s volatility, who knows how long that will last?

俄罗斯央行副行长将区块链应用划分为两个主要用例



据Cointelegraph消息,俄罗斯央行第一副行长奥尔加·斯科罗博加托娃将区块链应用划分出两大用例:首先,区块链系统可以用于银行支付处理的分布式结算基础设施,比如Ripple和Corda;其次,可以提供智能合约功能的区块链平台,比如以太坊和超级账本。

First Deputy Governor of the Russian Central Bank Olga Skorobogatova has said that blockchain technology is not yet “mature” enough for industrial-scale use, local media outlet Prime reports today, May 26.

During a discussion at the St. Petersburg International Economic Forum, Skorobogatova suggested that the emerging technology still requires improvements. According to her, the technology has not yet been applied on an industrial scale, except for its use for cryptocurrencies, such as Bitcoin. The Deputy Governor focused on security and scalability as key issues that still need to be resolved before industrial scale implementation can take off.
Skorobogatova divided blockchain applications into two major use cases. Firstly, blockchain systems that offer a distributed settlement infrastructure, such as Corda and Ripple, that can be used for banks’ payment processing. Secondly, blockchain platforms that provide smart contract functionality such as Ethereum and Hyperledger.
"Technology for the sake of technology is pointless,” Skorobogatova said, adding that 2018 would be the year that Russia and the international community would come to “a pragmatic understanding” of the purposes for which blockchain is beneficial, after which they would transition to tackle industrial scale realization.
Skorobogatova has previously spoken of blockchain as “a revolutionary technology [that] certainly needs to be invested in,” while highlighting that understanding the associated risks and how to manage them was essential for the mainstream financial sector. Fully-controlled integration would require “seven to ten years,” according to her estimation in June of last year.
Just this week, news was released that the country’s first officially regulated ICO would be tested using the Russian central bank’s newly-established regulatory sandbox, with major state-owned Sberbank acting as the project’s anchor investor.
Also this week, the Russian parliament approved the first of three readings of new laws regulating the crypto and blockchain industries, which define both cryptocurrencies and crypto tokens as property.

灰度投资公司总经理:要么繁荣要么萧条 比特币没有第三条路可走


这和聪爷的八年前的说法一样的。

中本聪2010年的时候就说,不成功,便归零。

二十年后,比特币网络上要么有天量交易,要么就没有交易。

Bitcoin will succeed, or it will not. There's no 3rd option.

Right.  Otherwise we couldn't have a finite limit of 21 million coins, because there would always need to be some minimum reward for generating.  In a few decades when the reward gets too small, the transaction fee will become the main compensation for [mining] nodes.   I'm sure that in 20 years there will either be very large transaction volume or no volume.
