A Reddit discussion on increasing the bitcoin block size clarified why many are opposed to the bitcoin hard fork.

A poster asked Bitcoin Core developers to explain their vision on increasing the block size. The poster claimed to be “very strongly anti-Bitcoin Unlimited (BU) but mildly in favor of bigger bitcoin blocks. BU has been proposed as a solution to scaling the bitcoin network that will hard fork the bitcoin blockchain.

“Please, educate me on your view as to if the max block size should ever change, if not why not, if yes how,” the poster asked.

Block Size Change Needed

In response, a luke-jr, a bitcoin core developer, recognized the need to eventually increase the bitcoin block size. He said people are not running nodes since the full node percentage is far below the safe 85%. “If you ask people why they don’t run a node, the reason is often tied to the block size,” luke-jr wrote.

In addition, miners are skipping the validation task due to the amount of time it now takes to verify large blocks, he added.

Core developers have conceded all possible compromises for increasing the block size, luke-jr noted. Even Segregated Witness (a solution to address the bitcoin network scalability challenge that has garnered support from many bitcoin users), is being proposed with a block size increase to as much as 3 MB, luke-jr noted.

Urgency Not Needed

Luke-jr does not think an increase in the block size is needed at the present time. A 1 MB block size is sufficient for the near term. When that size no longer suffices, the Lightning protocol (a system that allows faster transactions by doing them off of the network chain) will likely be in production, improving blockchain efficiency. It could reduce 1 MB block usage to around 10,000.

Luke-jr conceded that a block size increase will eventually be needed, but this is several years if not decades away. The scalability problems could resolve themselves by that time.

The decision to support a hard fork, for its part, is one that the community makes, luke-jr noted, and not a niche group, be it miners, developers or anyone else. The majority of the user community has rejected hard fork proposals.

The developer further noted that he himself proposed a minimal block size increase in seven years, only to meet “significant opposition.”

No To A Hard Fork

While the Bitcoin Core team has invested significant time in research and development in a future hard fork, the solutions at the present time are unsafe.

In response to luke-r, one Reddit poster noted that they don’t run nodes on account of the hassle it requires, and that 300 KB blocks or a 1 MB block won’t change this. The greater factor in falling node count is the emergence of usable thin clients such as Electrum and MyCelium.

Another poster noted that block size is not the reason people don’t run nodes; it is the lack of incentive for doing so.

Still, another poster pointed out that incentives do exist when making regular transactions, but they were unsure that increasing the block size to as much as 5 MB would increase the node count.

Schism Developing Between Lightning Network and Bitcoin Core Developers
The latest developments in the Cryptowar are what appears to be a developing schism between some Lightning Network developers and contributors to Bitcoin Core after Joseph Poon, a Lightning Network developer, Stephen Pair from BitPay, Christopher Jeffrey from Purse and Fedor Indutny, published an extension blocks proposal that both increases on-chain capacity and fixes malleability.

Discussions are heated in somewhat private conversations with one source calling an exchange between Matt Corallo – a former Blockstream employee and Bitcoin Core developer – and Jospeh Poon, as “nasty.”

In semi-public discussions, Poon said yesterday that “the extension block proposal is… a litmus test for corruption in the Bitcoin community.” He further added that “Core is getting what they want (soft fork plus malleability fix), but oppose due to nonsensical reasons.” Before saying “without the ability to make pragmatic decisions Bitcoin as a project is stagnant and dying.”

Corallo said that “extension blocks are a very bad idea,” before adding that “much of the western businesses I’ve asked have no interest in any extension block proposal.” He was asked to name the businesses by a discussion participant but failed to do so.

Interestingly, Poon said that “a malleability fix simpler than SW is provided on the extension block and Lightning on the extension block is superior to SW.” David Chan clarified to say “lightning is safer because there is a baked in pre-allocated space for two LN transactions per extension block. Helps defend against the catastrophic cascade closure of LN channels.”

Poon told CCN that segwit can still be activated with small changes. Clarifying the on-chain capacity that would be added, he stated it would be 3MB, up to 9MB. He further said that “this includes a malleability fix whose individual component is smaller than segwit, as it does not use the weights and discounting.”

The main criticism by other Bitcoin Core developers appears to be regarding timing. Eric Lambrozo, for example, said it would “lead to further development delays since [it] will still require review, obligatory bikeshedding (i.e. determining DoS parameters), testing, implementation, building ecosystem support, adapting existing applications, etc…”

Some Bitcoin Core developers have called the proposal as “technically sound,” while others have used the general argument against soft-forks and applied it to extension blocks. Overall, it appears opinion among Bitcoin Core supporters, including developers, is mixed.

As for miners, CCN has learned F2Pool supports the proposal. Bitfury and BTCC have not yet clarified their stance. If they do support extension blocks, consensus might be within reach, especially as this proposal is a soft-fork.

That means a chain split is very unlikely according to the usual arguments in favor of soft-forks by Bitcoin Core developers. That’s because old nodes can continue to operate, rather than being cut-off the network as would be the case in a hard-fork. As such, it’s opt-in, according to the extension blocks proposers, as well as backwards compatible.

That also means unanimous consensus is not necessary because it’s opt-in. Those not in favor of the proposal can simply just not upgrade, continuing as they are, while others can use the new features, allowing both groups to co-exist within one chain.

It provides to both sides what they want, according to extension blocks proposers. The bigger blocks side gets on-chain capacity, Bitcoin Core gets a malleability fix, allowing for the Lightning Network and other layer two protocols.

A Grand Compromise?

“This latest move is technically very clever, and politically brilliant.” – Emin Gun Sirer, Cornell Professor, told Forbes. You’d think so, but we’ll have to wait and see as, despite providing a malleability fix, Blockstream current and former employees are strongly arguing against it. Their reasons, however, appear hallow. As stated earlier, they amount to general arguments against soft-forks (despite arguing in favor of soft-forks for years), and arguments that it would lead to further delays.

Poon said that extension blocks were implemented in two weeks, “we can test and deploy within months.” Alex Petrov of Bitfury gave a time estimate of around 5-6 months, that’s this autumn/winter.

If such timeline can indeed be achieved then bitcoin might come out stronger, but seeing as Blockstream employees seem to be against it, any merging in Bitcoin Core appears difficult. The proposers say they will flesh out the details, and while it’s not clear whether a pull request will be made, you’d think they will do so.

In such event, it will all come down to one man, Wladimir J. van der Laan, the current maintainer of Bitcoin Core, who has the power to merge the proposal or otherwise. If he does merge, as he did segwit despite it clearly being highly controversial, then the Cryptowar may be over. If he doesn’t, then so-long bitcoin.

Because this currency can’t continue for much longer with such high fees and sometimes delays of days to move value from a to b in this 21st century. And, while I have no views on this specific proposal, I’d welcome whatever breaks this stalemate because this entire debate is becoming far too boring.

Everything that had to be said has been said. It’s now up to businesses and miners to pick something and just get on with it or users and businesses will continue leaving, as will the focus and attention of those who do sort of continue to stay.

An Indian politician who has previously raised his concerns on the growth of bitcoin in the country has, once again, urged the Indian government to weigh in on the cryptocurrency’s legality. More pointedly, the bitcoin critic is urging the Indian government to deem the cryptocurrency illegal.

Kirit Somaiya, a member of the Indian Parliament who belongs to the BJP, India’s conservative ruling party at the center, questioned if bitcoin is a ‘pyramid ponzi scheme’ during a session of the Indian parliament on March 24. At the time, the politician cited unnamed experts to base his concerns of the world’s largest cryptocurrency – now a legal method of payment in Japan – being a pyramid scheme and called for Indian financial authorities to regulate bitcoin.

In response, the Union Minister of State if Finance revealed a written reply to Somaiya, one that triggered much of the Indian media to falsely report that bitcoin was deemed illegal by the government.

A local report has since surfaced pointing to the formation of an ‘inter-ministerial’ committee installed by the Indian Parliament to study the legality of the popular cryptocurrency. It is speculated that the committee is tasked to give an initial announcement about its findings on April 20.

However, not content with these developments, Somaiya has once again raised his issue with bitcoin in India in the parliament on Wednesday afternoon. The bitcoin critic spoke during the ‘zero hour’, a session that starts at 12 noon wherein members of parliament are allowed to raise important subjects in the house.

In the Lok Sabha (the Lower house of the Indian parliament) session today, Somaiya opined that bitcoin was growing ‘without any restrictions’ in the “name of blockchain” technology. Unlike earlier, however, the politician has matter-of-factly stated that bitcoin is ‘illegal’ as a parallel currency. He then urged the government to ban bitcoin immediately, before drafting regulations for the industry.

Today again I raised Bitcoin issue in Parliament in zero hour It's illegal & unregulated in India Urged Govt for early action @BJP4India pic.twitter.com/zSpV5T9x5w

— Kirit Somaiya (@KiritSomaiya) April 5, 2017

Somaiya’s translated statements read:

Bitcoin trading worth ₹2000 crores (approx. $300 million, a day) has been initiated. This can also be used in underworld trading. Last week some students were caught dealing with drugs and LSD. In the name of block chain and crypto currency these kind of schemes are growing without any restrictions. The government has made a committee to address this. I urge them to declare this parallel currency illegal, and make rules and regulation to deal with it as soon as possible.

As it stands, the bitcoin industry remains unregulated in India with the Indian central bank issuing a public notice stating bitcoin companies in India were not recognized or approved by the authority. The notice, a rehash from December 2013, has spurred the Indian bitcoin industry to establish its own self-regulatory body and watchdog in February, one that approached Indian authorities but has yet to receive a response.

The Indian bitcoin industry has also launched a petition urging Indian lawmakers to declare the legality of bitcoin. Launched last week, the petition now sees over 10,000 signatures.

“However, he still has not given an estimated launch date.”
BlackCoin has been delivering content for payment for over a year now, with Paspagon. Why would I want to trust a 3rd party with storing my digital “for sale” items, when I can run it all myself and not involve a middle-man ? I see no mention of how much end users of Bitcache are protected or charges for this service … or even when it might actually be open to the public.I think i will stick with BlackCoin/Paspagon

I have long thought that the solution would be an all of the above kind of option. I do believe we need SegWit to activate and would love for this idea to get quick and thorough development and testing. The moment is coming when Bitcoin will get a huge influx of new users and money. When that happens, we will either be ready and go to a new level, or not and never do so.

So 260,000 stores ? It’s great news ! but Bitcoin is not able to handle a volume of 1 transaction per day per store right now. 300.000 is about the maximum per daily volume it can handle. + no instant transaction so how is that going to work ?

Someone has said bitcoin is of no value, in my heart I think they said is wrong, I always think that bitcoin is valuable, but I didn't understand what is the origin of the value of bitcoin, why accept more people, its value will rise? If you have other ideas, please discuss.

I am in a good price to sell a part, and then bought a few coins, collectively I, no loss, but also made a point. Now the price is also very optimistic, the same, I think the right price I choose to sell part of the reservation part.

“If there’s a “secret” or “hack” to learning a new language, it’s this: hours and hours of awkward and strenuous conversation with people better than you in that language. An hour of conversation is as good as five hours in a classroom and10 hours with a language course by yourself.”

Legislators gathered on Wednesday afternoon to hold a public hearing on a measure that would prohibit cannabis firms in the state of Washington from working with bitcoin.

CoinDesk reported last week that SB 5264, a bill presented by two Washington state senators, would ban businesses working in the marijuana industry from both selling products for bitcoin as well as purchasing them with the digital currency. At the time, primary sponsor Sen. Ann Rivers said that the measure was intended to boost financial transparency to the state’s cannabis sector as part of an effort to “help move it out of the shadows”.

The move sparked headlines and at least one petition aimed at stopping the measure in its tracks. Yet before the bill can become law, it has to move through the legislature, setting the stage for events like Wednesday’s hearing before the Washington Senate Commerce, Labor & Sports Committee.

The hearing drew a mixture of support and opposition for the bill, during which lawmakers asked a number of questions about the tech. Also appearing were representatives for the Washington State Liquor and Cannabis Board, which has called for businesses in the state to shift toward electronic payments.

Among those speaking against the measure were representatives from Posabit, a bitcoin point-of-sale developer based in Seattle.

In remarks, co-founder and CEO Ryan Hamlin spoke about the concerns among cannabis business owners who face the risk of robbery – a trend in the US affecting marijuana shops that rely on cash because they’re effectively locked out of the banking system owing to the nature of their business.

Hamlin told committee members:

"Anyone can Google about the robberies that are happening. Cash in this environment is a problem."

Hamlin reiterated the focus on store owner safety, arguing that "we are removing cash from the system which is helping our customers become safer".

Yet another payments company servicing marijuana firms in the industry expressed strong support for the bill. PayQwick offers payment services to businesses and consumers in the space, as well as cash handling services.

Kenneth Burke, the firm’s CEO, invoked the newly-minted Trump administration and the as-yet-unconfirmed US Attorney General nominee, Sen. Jeff Sessions in his statements. Sessions, who according to Politico has called marijuana legal reform a "tragic mistake", is likely to enforce the federal ban on marijuana more decidedly than the Obama administration.

"I think allowing bitcoin in consumer transactions in Washington is just going to invite extra scrutiny from Sessions and the federal government," Burke told the panel.

On traceability

One point of contention during the hearings was the question of whether bitcoin transactions are traceable.

Among those was Burke, who argued that "with bitcoin, there’s just no traceability to it".

But on the contrary, every bitcoin transaction is published to the public blockchain. Instead of being attached to a particular identity though, bitcoins are attributed to pseudonymous addresses. Actual identification of a user happens outside of the bitcoin system itself, as in the case of an exchange conducting a know-your-customer process.

Joseph Cutler, a partner for the law firm Perkins Coie who is based in the Seattle area, disputed the notion that bitcoin transactions can’t be traced.

“This idea that it’s untraceable is simply false. People also say bitcoin is anonymous,” he told the panel. “This is also false. We like to call it pseudonymous, which is better than cash.”

Cutler went on to invoke once again the problematic use of cash in cannabis businesses.

“In the marijuana space, for example, cash is king,” he said, adding:

“And there is no traceability to the customers for the cash they’re using in those stores.”

真为这人的智商捉急

印度这样的事情实在是太多了，不得不说，女人生活在这样的国度只能用悲哀来形容

探索无极限，宇宙的奥秘不知道得多少年才能挖掘

时间虽然已近年末，中南建设“颠覆”“区块链”的战略动作，似乎完全停不下来。

1月18日，中南建设发布公告，拟出资3亿元与他人合资设立中南建设区块链农业发展（深圳）企业(有限合伙)(暂定名)（以下简称“合伙企业”）并占股99%。

公告显示，合伙企业的唯一目的是以股东身份与黑龙江北大荒农业股份有限公司（以下简称“北大荒股份”）合资成立北大荒粮仓股份有限公司（暂定名）（以下简称“北大荒粮仓”）。

令人关注的是，在去年11月以来的短短三个月里，中南建设已经在区块链领域扔下了三枚“重磅新闻”。

据了解，《关于合资设立中南建设区块链农业发展（深圳）企业(有限合伙) (暂定名)并联合投资的议案》已经通过中南建设1月17日举行的董事会审议,目前正在等待工商行政部门的批准。

“今年3、4月，中南建设将联合北大荒，举行全球首个区块链大农场的发布会“中南建设相关人士表示，“届时，我们将针对‘区块链’技术在‘大数据农业’方面的场景应用和经营方式，进行介绍和推介。”

“区块链+农业”

根据上述公告，在合伙企业成立之后，中南建设将通过该公司出资3亿元，与北大荒股份共同成立北大荒粮仓，经营范围包括但不限于咨询、数据分析、软件开发、农产品仓储、贸易代理、互联网信息服务业务、农产品收购、农产品的批发与零售、社会经济咨询服务等。

资料显示，北大荒股份是我国目前规模最大、现代化水平最高的种植业上市公司和重要的商品粮生产基地，拥有耕地1158万亩，具有明显的规模、资源、技术、装备、管理及绿色产品优势。
 
按照公告内容，北大荒将负责建设农业服务平台项目所需技术、设计和运营方案、合资公司的组织建设和运营资金等，并为合资公司提供为农业分公司与农产品电商平台、农业生产管理系统以及农业物联网系统的相关数据。其中，包括但不限于北大荒股份或北大荒股份通过第三方采集的相关土地、农户、生产种植、交易等产业数据。

另外，北大荒股份为合资公司收集、提供、更新上述数据、APP 推广、农业服务及其他业务总包服务，在合资公司成立三年内以每年300 万元的固定价格向合资公司收取服务费

北大荒股份还将为合资公司推荐相关的合作资源和农业专家。

事实上，区块链技术做为认证追溯的应用，是当前区块链技术应用之一。利用不可篡改和时间戳的特性，虽然区块链在奢侈品、疫苗等物品流转环节有所应用，但在农产品生产、流通方面的应用，却十分“稀缺”。

毫无疑问，“区块链+农业”的战略组合，正在打开了“大数据农业”新天地的大门。

中南建设表示，该项目的合作对于本公司转型区块链领域项目落地有着重要意义，北大荒股份已经完成其16家下属分公司（农场）1000多万亩农业用地的物联网信息系统的建设、运行。合资公司基于农业物联网生成的原产地农业大数据打造农产品交易平台和金融平台，以区块链技术作为底层建立封闭农产品供应及农产品区块链认证追溯体系，为消费者提供放心农产品，符合本公司区块链战略转型方向， 有助于进一步推进区块链技术在场景的落地，同时公司可以利用大数据征信体系为农户提供供应链金融服务。

中南建设相关人士进一步表示，将通过引进国际知名的区块链应用专家顾问对此项工作进行指导， 在后期的电商交易平台运营方面也需要专业人士的引入确保项目整体有效运营。

“大数据农业”新想象

“在3-5年内，中南建设将和北大荒展开全面的战略合作，共同出资30到50亿资金，致力于利用最新的科技金融手段服务农业发展，解决中国的粮食安全，促进中国老百姓的收入增长。”中南建设表示，“2017年3或4月，合资公司将针对“区块链”技术在“大数据农业”方面的应用举行发布会，进行场景介绍和推介。”

可以看到，中南建设和北大荒这两家原先根本“不搭界”的企业，正在全面展开，筑造新的“大数据农业”想象。

“区块链技术被誉为是引发全球金融体系革命的技术，2016年金融科技市场在亚洲实现了爆发式增长，特别是在中国获得了突飞猛进的发展。”全球区块链理事会(GBBC)常务理事彭耀杰表示。

值得注意的是，去年12月以来，农业供给侧改革的新“风口”似乎正在形成。

2016年中央农村工作会议强调：“要持续抓好‘三农’工作，大力推进农业供给侧结构性改革，加快现代农业建设，积极调整农业结构，发展多种形式适度规模经营，深入开展农村‘双创’，推动新型城镇化与农业现代化互促共进。

根据清科研究中心发布的《中国农业行业投资现状及未来趋势》研究报告分析，从2013年起，农业产业股权投资热度剧增。截至2015年底，农业领域投资案例数达498例，相比2013年增加300%，投资金额达103.99亿美元，相比2013年增长460%。

分析人士指出，当下，中国农业正处于从近代化农业朝着现代农业全面演进的阶段，而在这个过程中，资本与技术的结合，将产生风暴级的化学反应，带来整个产业的颠覆与重构。其中，“大数据农业”将对生产、流通、经营、金融服务、人才培养等农业产业链各环节进行深度改造，促进农业将向信息化和智能化转型升级，优化农业供给侧，提升农业运营效率和质量，逐步实现智慧农业、精准农业和高效农业。

对此，中南建设表示：“我们和北大荒，将致力携手通过区块链技术，构建自治溯源的封闭体系，让中国人吃上放心粮。“

毫无疑问，“大数据农业”对农业的颠覆与重构是全局性的。

“大数据”战略矩阵

短短三个月，中南建设在抢占“大数据”战略高地过程中，又落下一枚重要“棋子”。

就在稍早前的2016年11月8日，中南建设发布公告称，拟参与美国PeerNova的pre-B轮融资可转换票据投资，并与其合资设立国内公司共同推广区块链技术在银行等领域的应用。

而在去年12月15日，中南建设宣布拟出资1亿元投资有“中国区块链第一股”之称的新三板公司金丘股份，投资完成后中南建设将占金丘股份总股本的33.33%。

事实上，中南建设早将“区块链”技术投资视为其大数据布局的一个重要突破口。

2015年底，中南建设将大数据做为公司转型方向，先后投资了上海承泰、美人信息、大家保等一系列拥有行业数据存储和商业应用的公司。而区块链技术的分布式账本数据共享、数据安全、数据资产的流通等特征使得这些公司在区块链技术上的大数据运用会更加的便捷、可信任。

虽然区块链技术概念很热门，但实际的运用较少，中南建设表示，将充分利用的金丘股份的区块链技术，并与此前所投资的公司相结合，构筑公司在大数据和区块链领域的核心竞争力。

“中南建设将通过投资PeerNova和金丘股份所获得的区块链技术，共同支持公司在农业场景中的应用。“中南建设对此介绍称，该公司在区块链领域的“矩阵”正在形成。

可以预见，中南建设未来还将持续加速进行区块链领域的战略布局，以尽快实现将国内外领先区块链技术推广应用于各类行业场景的战略目标。

为期四天的2017年度达沃斯论坛即将落下帷幕。中国国家主席首次出席论坛并发表主旨演讲，习近平主席指出泛全球化并非当今世界问题的根源。坚持创新驱动，打造富有活力的增长模式才是纾解全球问题的关键。全球期待公正、公平、合理的治理模式。

本次论坛的焦点是聚焦互联网金融和工业革命。世界经济论坛(即达沃斯论坛)创始人克劳斯·施瓦布(Klaus Schwab)说，自蒸汽机、电和计算机发明以来，我们又迎来了第四次工业革命——数字革命，而区块链技术就是第四次工业革命的成果!“区块链”成为达沃斯世界经济论坛的最热门话题。

2016年1月17日，包括中国代表在内的来自25个国家的政府和企业的150位代表齐聚达沃斯论坛，原美国总统奥巴马的新闻发言人及特别助理Jamie Elizabeth Smith宣布全球区块链商业理事会（GBBC）正式成立，多国重量级成员参与（发起国家代表名单附后），大会发布了达沃斯区块链宣言。

全球区块链理事会（GBBC）一经成立，便获得社会的广泛关注和社会的强烈反响，多家媒体竞相报道，在美国的知名媒体Econotimes上也荣登most popular榜单。很显然，不管外界曾对区块链技术如何置喙，现在它的价值毋庸置疑，并即将开启一个新时代。

瑞士达沃斯召开的论坛年会一直是全球创新、合作、发展的前沿力量。本届达沃斯论坛首次提及区块链技术，并发布技术解说视频。在展现该技术巨大应用潜力的同时，也让所有关注该技术趋势的人对其有更大的信心。预计未来该领域的资金投入将达到千万，甚至上亿美元。

翻译：Annie_Xu

世界经济论坛（World Economic Forum）每年在瑞士达沃斯召开学者、企业家、决策者大会的全球性机构，公布了一份区块链技术解说视频。使该技术不再是一时的流行，而具备了更高的可信度，一项值得全球密切关注的技术。

达沃斯论坛解说区块链技术

达沃斯论坛是每年思想政治领袖讨论重要的全球经济及稳定话题的会议。今年该论坛开始关注区块链技术，因此是该技术合法化的重要事件。会议将比特币看成去中心化、无需银行的货币系统，赞扬了区块链在金融应用中的重要意义。包括各种金融交易的清算结算、付款的追踪和记录、税收和后端文件流程的简化。视频指出去年银行业区块链项目投入大约是7500万美元，预计2019年将突破4亿美元。
除金融用例外，达沃斯论坛视频中提及了其他的新应用，比如打击盗版音乐、网络诈骗，搭建安全的身份认证系统，甚至贩卖人口。

“该技术可以应用于几乎所有类型的价值交易，包括货币、商品、财产。其潜在用途几乎是无止尽的，从收税，到让移民向银行服务落后的家乡汇款。区块链还可以减少诈骗，因为每笔交易可以记录在所有人可以使用的公共账本上”。

本届达沃斯论坛开始讨论区块链技术，参会者包括发达国家的思想领袖、决策者；这样的会议奠定了区块链技术在金融业等领域的可信度，未来该技术领域的投入将达到千万，甚至上亿美元。

鉴于区块链对于全球金融系统存在的潜在影响力，该技术是一种“重要技术”，美联储主席Janet Yellen于近日讲到。

Yellen在美国历史最为悠久、规模最大的公共事务论坛Commonwealth Club上发表了演讲，随后又和俱乐部董事会主席George Scalise参加了问答环节。

Scalise向Yellen发问道，鉴于美联储曾在12月份发布了关于分布式账本的首份研究文件，美联储是否有打算自行使用该技术？

Yellen如此回应：

“区块链是一项非常重要的新技术，它会对金融系统的交易方式产生重要影响。我们正在研究区块链技术在美联储及许多金融机构当中的应用前景。区块链会对全球经济的交易清算和结算方式产生重大影响。”

在某种程度，Yellen的评论也与去年9月份的言论呼应，当时美联储主席曾告诉国会委员会区块链技术会对美国支付生态环境产生非常重要的影响。

“我认为这些技术的创新是极其有益的，而且能惠及全社会。”她当时讲到。

美联储目前正对区块链技术进行深入的研究，同时今年也将发布后续的研究文件。

在经济危机和金融动荡日益恶化之际，委内瑞拉民众正在搜寻替代性资产和价值存储来解决他们的日常生活。而黄金等实体资产却受到严格的监管，这就促使了比特币在这个正在挣扎中的国家的需求大增。
委内瑞拉因为饥饿而死亡的儿童人数正在增加，某些地区的军事人员甚至开始诉诸武力走私食物到该国，居民正在努力获得基本的生活必需品，如药品。

2016年12月份，《纽约时报》深入地报道了委内瑞拉目前毁灭性的金融经济状况，其中包括Nicholas Casey发表的“饥饿的委内瑞拉民众正在乘船逃离金融崩溃”准确地展示了这个国家的经济和货币体系的崩溃。

美联社刚刚发布了一份报告，描述了严重的现金短缺已经使该国人民无法购买足够的食物和药品来支撑家庭。因此，人民正在乘船穿越边境进而移民到哥伦比亚，而军事人员正在往该国走私食物来卖给饥饿的人民。
人民转向比特币
 

委内瑞拉的比特币市场并不是非常大。由于目前糟糕的金融状况，该国只占到全球比特币交易所市场的很小的一部分。

然而，越来越多的人们正在转向比特币，从而尝试获得一种具有现实价值且能够换取基本必需品的货币。

从学生到企业所有者的个体都有被报道成功进行了比特币挖矿，并使用挖出的比特币在接受比特币的在线市场购买商品，如食物和药品。一些学生正在使用比特币服务提供商，如Purse.io，在亚马逊上订购食品。

一些媒体还报道，在委内瑞拉，谷歌关键字“比特币”的搜索量在过去几个月增长了400%，人们都在寻找替代性货币或资产来支撑他们的生活。

考虑当前委内瑞拉的金融趋势，像比特币这样的货币完全可以取代本国货币，这些国家货币如今已经价值不大。而去中心化货币并不需要政府机构的许可来进行交易结算，能够直接在彼此之间进行支付。

 我觉得这个可以全国推广，左立右行真的加快电梯磨损，有人会说那上行一段时间后再改为下行不就好了？仔细想想 这样只会加剧两边的磨损吧，只有两边同时受力均衡，才是磨损最小的。
