这应该是区块链最简单的应用场景，就是信息互通有无。
This should be the simplest application of the block chain, i.e. information sharing.
1、传统的信息共享的痛点
1, the pain of traditional information sharing
要么是统一由一个中心进行信息发布和分发，要么是彼此之间定时批量对账（典型的每天一次），对于有时效性要求的信息共享，难以达到实时共享。
Either there is a single centre for information dissemination and distribution, or a regular batch reconciliation (typically once a day) between them, which is difficult to share in real time for information-sharing that is subject to time-bound requirements.
信息共享的双方缺少一种相互信任的通信方式，难以确定收到的信息是否是对方发送的。
There is a lack of mutual trust between the parties sharing information to determine whether the information received was sent by the other party.
2、区块链 + 信息共享
首先，区块链本身就是需要保持各个节点的数据一致性的，可以说是自带信息共享功能；其次，实时的问题通过区块链的P2P技术可以实现；最后，利用区块链的不可篡改和共识机制，可构建其一条安全可靠的信息共享通道。
First, the block chain itself needs to maintain data consistency across nodes, which can be described as a self-contained information-sharing function; secondly, real-time issues can be achieved through P2P technology in the block chain; and finally, a secure information-sharing channel can be constructed using the inexorable alteration and consensus mechanism of the block chain.
也行你会有这样的疑问：解决上面的问题，不用区块链技术，我自己建个加密通道也可以搞定啊！但我想说，既然区块链技术能够解决这些问题，并且增加节点非常方便，在你没有已经建好一套安全可靠的信息共享系统之前，为什么不用区块链技术呢？
But since block chain technology can solve these problems and it is convenient to add nodes, why not use block chain technology until you have a secure and reliable information-sharing system in place?
3、应用案例
举下我们腾讯自己的应用--公益寻人链，借用如下一张好图，可以看到，区块链在信息共享中发挥的价值。
By drawing on our own application, the public interest search chain, and using a good map, we can see the value of the block chain in information-sharing.
1、传统鉴证证明的痛点
1, the pain of traditional forensic evidence
流程复杂：以版权保护为例，现有鉴证证明方式，登记时间长，且费用高。
Complex processes: In the case of copyright protection, existing methods of forensic certification, long registration times and high cost.
公信力不足：以法务存证为例，个人或中心化的机构存在篡改数据的可能，公信力难以得到保证。
Credibility is inadequate: in the case of forensic evidence, there is the possibility of tampering with data by individuals or centralized institutions, and credibility is difficult to guarantee.
2、区块链 + 鉴证证明
流程简化：区块链应用到鉴证证明后，无论是登记还是查询都非常方便，无需再奔走于各个部门之间。
Process simplification: Once the block chain has been applied to forensic certificates, both registration and searching are very easy and do not need to travel between departments.
安全可靠：区块链的去中心化存储，保证没有一家机构可以任意篡改数据。
Safe and reliable: Decentralized storage of block chains ensures that no agency can tamper with data at will.
3、应用案例
区块链在鉴权证明领域的应用有版权保护、法务存证等，下面以版权保护为例，简单说下如何区块链如何实现版权登记和查询。
The blocks chain is applied in the field of recognition of rights in the form of copyright protection, legal documentation, etc. For example, copyright protection is used to describe briefly how the blocks chain achieves copyright registration and search.
（1）电子身份证：将“申请人+发布时间+发布内容”等版权信息加密后上传，版权信息用于唯一区块链ID，相当拥有了一张电子身份证。
(1) Electronic ID card: “ applicant + time of issue + release & & rdquo; copyright information is uploaded after encryption, copyright information is used for the only block chain ID, and an electronic identity card is fairly available.
（2）时间戳保护：版权信息存储时，是加上时间戳信息的，如右雷同，可用于证明先后。
(2) Time stamp protection: when copyrighted information is stored, it is added to time stamp information, which can be used to demonstrate priority if the right type is the same.
（3）可靠性保证：区块链的去中心化存储、私钥签名、不可篡改的特性提升了鉴权信息的可靠性。
(3) Assurance of reliability: Decentralized storage of block chains, private key signatures, non-alterable features enhance the reliability of forensic information.
2016年8月，由Onchain、微软（中国）、法大大等多个机构在北京成立了电子存证区块链联盟“法链”。
In August 2016, several institutions, such as Onchain, Microsoft (China) and Ljuana, established the Electronic Recording Block Chain Alliance & ldquo; the French chain & rdquo in Beijing.
2017年12月，微众银行、仲裁委（广州仲裁委）、杭州亦笔科技有限公司共同推出的仲裁联盟链，用于司法场景下的存证；2018年3月，广州首个“仲裁链”判决书出炉。
In December 2017, a chain of arbitration alliances was launched by the Microbanks, the Arbitration Commission (Huangzhou Arbitration Commission) and Hangzhou and Technology Ltd., for use as evidence in the judicial scene; in March 2018, the first & ldquo in Guangzhou; in the arbitration chain & rdquo; and in the judgement.
商品从生产商到消费者手中，需要经历多个环节（流程可能如上图所示），跨境购物则更加复杂；中间环节经常出问题，消费者很容易购买的假货。而假货问题正是困扰着各大商家和平台，至今无解。
From producer to consumer, goods need to go through multiple links (the process may be as shown in the figure above), and cross-border shopping is more complex; the middle is often problematic, and consumers can easily buy fake goods. And the problem of counterfeits is precisely what plagues major businesses and platforms, and so far it has not been solved.
1、传统是防伪溯源手段
1, traditional means of protection against forgery
以一直受假冒伪劣产品困扰的茅台酒的防伪技术为例，2000年起，其酒盖里有一个唯一的RFID标签，可通过手机等设备以NFC方式读出，然后通过茅台的APP进行校验，以此防止伪造产品。 咋一看，这种防伪效果非常可靠。但2016年还是引爆了茅台酒防伪造假，虽然通过NFC方式验证OK，但经茅台专业人士鉴定为假酒。后来，在“国酒茅台防伪溯源系统”数据库审计中发现80万条假的防伪标签记录，系防伪技术公司人员参与伪造；随后，茅台改用安全芯片防伪标签。
For example, since 2000, there has been a single RFID label in the wine cap, which can be read in the form of NFCs and other devices, such as mobile phones, which can then be verified through APPs in the huts, in order to prevent counterfeiting of products. This security is reliable. In 2016, however, it was detonated, although it was verified through NFC, but was identified as fake by a professional. Later, in “ in the National Counterfeiting System & rdquo; in database audits, 800,000 false security tags were recorded, with the involvement of security company personnel; and subsequently, it was replaced with a security chip.
但这里暴露出来的痛点并没有解决，即防伪信息掌握在某个中心机构中，有权限的人可以任意修改。（备注：茅台的这种防伪方式，也衍生了旧瓶回收，旧瓶装假酒的产业，防伪道路任重而道远）。
But the pain revealed here has not been resolved, i.e., the security information is in the center of a central institution, and the right person can modify it at will. (Note: this pseudo-proof approach in the hut is also derived from the recycling of old bottles, the industry of old bogus bottles, and the road to prevention is a long way to go.)
2017年05月贵阳数博会上，小马哥就建议茅台防伪使用区块链；那么区块链和物流链的结合有什么优势呢？
In May 2017, at the Guiyang Expo, Little Pago proposed that the pseudo-use of block chains should be prevented; what would be the advantages of a combination of block chains and logistics chains?
2、区块链+物流链
区块链没有中心化节点，各节点是平等的，掌握单个节点无法实现修改数据；需要掌控足够多的节点，才可能伪造数据，大大提高伪造数据的成本。
Block chains do not have centralized nodes, nodes are equal, individual nodes are not capable of modifying data; sufficient nodes need to be controlled to make it possible to falsify data and significantly increase the cost of counterfeiting data.
区块链天生的开放、透明，使得任何人都可以公开查询，伪造数据被发现的概率大增。
The inherent openness and transparency of the block chain allows public access to anyone and the probability of counterfeiting data being detected increases significantly.
区块链的数据不可篡改性，也保证了已销售出去的产品信息已永久记录，无法通过简单复制防伪信息蒙混过关，实现二次销售。
The data in the block chain cannot be tampered with and also ensures that the information on the products sold is permanently recorded and that secondary sales cannot be achieved by simply copying the information against forgery.
物流链的所有节点上区块链后，商品从生产商到消费者手里都有迹可循，形成完整链条；商品缺失的环节越多，将暴露出其是伪劣产品概率更大。
After all the nodes of the logistics chain are connected, the goods are traceable from producer to consumer, forming a complete chain; the more missing the goods are, the more likely they will be exposed to hypocrisy.
3、应用案例
目前，入局物流链的玩家较多，包括腾讯、阿里、京东、沃尔玛等。 据说，阿里的菜鸟在海淘进口应用区块链上，走在了前面，已经初步实现海外商品溯源，国际物流及进口申报溯源、境内物流溯源；下一步就是生产企业溯源了。下图是网上流传的关于阿里的菜鸟在海淘场景运用区块链的示意图。
At present, there are more players in the logistics chain, including tweets, Ali, Kyundong, Wal-Mart, and so on. Ali’s rookies are said to be on the sea-drawn-in-the-sea-import application chain, leading to an initial back-up of overseas commodities, an international logistics and import declaration, and an internal back-up of logistics; the next step is the back-up of production enterprises.
另据最新消息，在3月份的第三届全球物流技术大会上，腾讯与中国物流与采购联合会（简称“中物联”）正式签署战略合作协议，并发布了区块链物流平台。强强联合，想象空间很大。
Also, at the third Global Conference on Logistics Technologies, in March, Tetsu formally signed a strategic cooperation agreement with the Chinese Federation of Logistics and Procurement (hereinafter & ldquao; Sino-China & & rdquao;) and launched a block chain logistics platform. There is much room for imagination.
1、传统的供应链单点融资
1, traditional supply chain single-point financing
在一般供应链贸易中，从原材料的采购、加工、组装到销售的各企业间都涉及到资金的支出和收入，而企业的资金支出和收入是有时间差的，这就形成了资金缺口，多数需要进行融资生产。我们先来看个简单的供应链（复杂的我也不了解（⊙o⊙）），如下图：
In general supply chain trade, the costs and revenues of the funds are involved between enterprises from the purchase, processing, assembly to sale of raw materials, while the time difference in the expenses and revenues of the enterprise creates a gap in financing, most of which requires production. We look first at a simple supply chain (a complex one I don't know), as follows:
我们再来看看图中各个角色的融资情况：
Let's look at the financing of the various players in the map: .
核心企业或大企业：规模大、信用好，议价能力强，通过先拿货后付款，延长账期将资金压力传导给后续供应商；此外，其融资能力也是最强的。
Core enterprises or large enterprises: large, well-credited and highly bargaining power, which transmits financial pressure to subsequent suppliers by extending the period for payment after taking delivery; in addition, it has the strongest financing capacity.
一级供应商：通过核心企业的债权转让，可以获得银行的融资。
First-tier suppliers: bank financing is available through the assignment of claims from core enterprises.
其他供应商（多数是中小微企业）：规模小、发展不稳定、信用低，风险高，难以获得银行的贷款；也无法想核心企业一样有很长的账期；一般越小的企业其账期越短，微小企业还需要现金拿货。这样一出一入对比就像是：中小微企业无息借钱给大企业做生意。
Other suppliers (mostly MSMEs): small, unstable development, low credit, high risk and difficulty in obtaining bank loans; unable to expect the same long term as the core business; the smaller the business, the shorter it is, the smaller the micro-enterprise needs cash. This contrasts with the fact that MSMEs have no interest in lending money to large businesses to do business.
2、区块链+供应链金融
面对，上述供应链里的中小微企业融资难问题，主要原因是银行和中小企业之间缺乏一个有效的信任机制。
Faced with the difficulty of financing MSMEs in the above-mentioned supply chain, this is mainly due to the lack of an effective trust mechanism between banks and SMEs.
假如供应链所有节点上链后，通过区块链的私钥签名技术，保证了核心企业等的数据可靠性；而合同、票据等上链，是对资产的数字化，便于流通，实现了价值传递。
If all nodes of the supply chain are chained, the reliability of data such as the core business is ensured through the private key signature technology of the block chain, while contracts, notes, etc., are digitized to facilitate the flow of assets and the transfer of value.
如上图所示，在区块链解决了数据可靠性和价值流通后，银行等金融机构面对中小企业的融资，不再是对这个企业进行单独评估；而是站在整个供应链的顶端，通过信任核心企业的付款意愿，对链条上的票据、合同等交易信息进行全方位分析和评估。即借助核心企业的信用实力以及可靠的交易链条，为中小微企业融资背书，实现从单环节融资到全链条融资的跨越，从而缓解中小微企业融资难问题。
As shown in the figure above, financial institutions, such as banks, are no longer subject to a separate assessment of SME financing when the block chain addresses data reliability and value flows; rather, they stand at the top of the entire supply chain and, by trusting the willingness of core firms to pay, carry out a full analysis and assessment of transactional information on the chain, such as instruments, contracts, etc.
3、应用案例
比较成熟的还没看到，目前腾讯也已入局。
The more mature ones haven't seen it yet, and they're in the game now.
1、传统跨境支付
1, traditional cross-border payments
跨境支付涉及多种币种，存在汇率问题，传统跨境支付非常依赖于第三方机构，大致的简化模型如上图所示，存在着两个问题；
Cross-border payments involve multiple currencies, exchange rate problems, traditional cross-border payments are heavily dependent on third-party institutions, and there are two problems with the general simplified model, as shown in the figure above;
流程繁琐，结算周期长：传统跨境支付基本都是非实时的，银行日终进行交易的批量处理，通常一笔交易需要24小时以上才能完成；某些银行的跨境支付看起来是实时的，但实际上，是收款银行基于汇款银行的信用做了一定额度的垫付，在日终再进行资金清算和对账，业务处理速度慢。
The process is cumbersome and the settlement cycle is long: traditional cross-border payments are mostly non-real-time, banks conduct bulk processing of transactions at the end of the day, usually taking more than 24 hours for a transaction to be completed; cross-border payments by some banks appear to be real-time, but in practice it is the receiving bank that makes a certain advance based on the credit of the remittance bank, then settles and reconciles funds at the end of the day, and the processing of operations is slow.
手续费高：传统跨境支付模式存在大量人工对账操作，加之依赖第三方机构，导致手续费居高不下，麦肯锡《2016全球支付》报告数据显示，通过代理行模式完成一笔跨境支付的平均成本在25美元到35美元之间。
High fees: The high level of manual reconciliation of traditional cross-border payment patterns, combined with reliance on third-party institutions, has resulted in high fees, and McKinsey's Global Payments 2016 report data show that the average cost of completing a cross-border payment through the agency model is between $25 and $35.
2、区块链+跨境支付
这些问题的存在，很大原因还是信息不对称，没有建立有效的信任机制。
The existence of these problems is largely due to asymmetrical information and the lack of effective trust mechanisms.
如上图所示，区块链的引入，解决了跨境支付信息不对称的问题，并建立起一定程度的信任机制；带来了两个好处。
The introduction of block chains, as shown in the figure above, addresses the asymmetry of information on cross-border payments and establishes a degree of trust mechanism; it brings with it two benefits.
效率提高，费用降低：接入区块链技术后，通过公私钥技术，保证数据的可靠性，再通过加密技术和去中心，达到数据不可篡改的目的，最后，通过P2P技术，实现点对点的结算；去除了传统中心转发，提高了效率，降低了成本（也展望了普及跨境小额支付的可能性）。
Efficiency gains and lower costs: access to block chain technology, reliability of data through public-private key technology and access to centres to achieve the goal of data inescapability, and, finally, point-to-point settlement through P2P technology; efficiency gains and reduced costs by removing traditional centre relays (also looking forward to the possibility of universal access to small cross-border payments).
可追溯，符合监管需求：传统的点对点结算不能不规模应用，除了信任问题，还有就是存在监管漏洞（点对点私下交易，存在洗黑钱的风险），而区块链的交易透明，信息公开，交易记录永久保存实现了可追溯，符合监管的需求。
Retroactivity, in line with regulatory needs: traditional point-to-point settlements cannot be applied on a scale-less basis and, in addition to trust issues, there are regulatory loopholes (point-to-point private transactions, risk of money laundering), while sector chain transactions are transparent, information is open, and the permanent preservation of transaction records is traceable and meets regulatory requirements.
3、应用案例
应用现状：Ripple、Circle、招商银行等已经入局。
Status of application: Ripple, Circle, Merchant Bank, etc. are in place.
1、实体资产存在的问题
1 ; physical assets
实体资产往往难以分割，不便于流通
Physical assets are often difficult to separate and not easy to circulate
实体资产的流通难以监控，存在洗黑钱等风险
The flow of physical assets is difficult to monitor and there is a risk of money laundering, etc.
2、区块链实现资产数字化
资产数字化后，易于分割、流通方便，交易成本低
digitized assets, easily divided, easily circulating and with low transaction costs
用区块链技术实现资产数字化后，所有资产交易记录公开、透明、永久存储、可追溯，完全符合监管需求
When assets are digitized using block chain technology, all asset transaction records are open, transparent, permanently stored, traceable and fully meet regulatory requirements
3、应用案例
还是以腾讯的微黄金应用为例，继续借用腾讯区块链官网（trustsql.qq.com）上的图片，可以看到，在资产数字化之后，流通更为方便了，不再依赖于发行机构；且购买0.001g黄金成为了可能，降低了参与门槛。
Or, for example, the micro-golding application, which continues to borrow pictures from the tweaksql.qq.com, shows that, after the digitization of assets, it is easier to circulate and no longer depends on the issuing agency; and that the purchase of 0.001 g gold is possible, lowering the participation threshold.
本来不像把代币加进来的，但说到区块链，始终绕不开代币；因区块链脱胎于比特币，天生具有代币的属性，目前区块链最成功的应用也正是比特币。
It would not have been like adding a token, but when it comes to the block chain, there is always no way to circumvent it; since the block chain is born in bitcoin, it has a natural intergenerational character, and it is bitcoin that is the most successful application of the block chain at the present time.
1、传统货币存在的问题
1, problems with traditional currencies
传统的货币发行权掌握在国家手中，存在着货币滥发的风险
Traditional currency issuance rights are in the hands of the State and there is a risk of currency abuse
元朝自1271年建立后，依然四处征战，消耗大量的钱财和粮食，为了财政问题，长期滥发货币，造成严重通货膨胀，多数百姓生活在水生火热中，导致流民四起，国家大乱，1368年，不可一世的元朝成了只有97年短命鬼，走向了灭亡。
Since its establishment in 1271, the Yuan dynasty has continued to wage war, consume a great deal of money and food, cause chronic currency and cause serious inflation, and the majority of the population has been living in hot and hot water, leading to the displacement of people. In 1368, the undying dynasty became a quick-life ghost of only 97 years.
1980年津巴布韦独立，后因土改失败，经济崩溃，政府入不敷出，开始印钞；2001年时100津巴布韦币可兑换约1美元；2009年1月，津央行发行100万亿面值新津元（如下图）加速货币崩溃，最终津元被废弃，改用“美元化”货币政策。2017年津巴布韦发生政变，总统穆加贝被赶下台。
The 1980 independence of Zimbabwe, followed by the collapse of the economy as a result of land transformation, the government began printing banknotes; the 2001 exchange rate of RM100 was about US$ 1; and in January 2009, the Central Bank of Zimbabwe accelerated the currency collapse with the release of SNZ 100 trillion in face value (see figure below), which was eventually abandoned and replaced with “ dollarized & RDquo; and monetary policy. President Mugabe was removed from office following a coup d'état in Zimbabwe in 2017.
传统的记账权掌握在一个中心化的中介机构手中，存在中介系统瘫痪、中介违约、中介欺瞒、甚至是中介耍赖等风险。
Traditional recording authority is in the hands of a centralized intermediary, with the risk of a breakdown of the intermediary system, breach of the intermediary's authority, fraud by the intermediary, and even fraud by the intermediary.
2013年3月，塞浦路斯为获得救助，对银行储户进行一次性征税约58亿欧元， 向不低于10万欧元的存款一次性征税9.9%，向低于10万欧元的一次性征税6.75%。
In March 2013, Cyprus imposed a one-time tax of approximately Euro5.8 billion on bank depositors and a one-time tax of 9.9 per cent on deposits of not less than Euro100,000, and 6.75 per cent on deposits of less than Euro100,000.
2017年4月，民生银行30亿假理财事件暴露，系一支行行长伪造保本保息理财产品所致，超过150名投资者被套。
In April 2017, the 3 billion pseudo-finance incident at the Bank was exposed as a result of the falsification by a governor of the preservation of the property, and more than 150 investors were set up.
2、区块链如何解决这些问题
比特币解决了货币在发行和记账环节的信任问题，我们来看下比特币是如何一一破解上面的两个问题。
Bitcoin solves the problem of trust in the issuance and recording of money, and we see how bitcoin solves the two above.
滥发问题：比特币的获取只能通过挖矿获得，且比特币总量为2100万个，在发行环节解决了货币滥发的问题； 账本修改问题：比特币的交易记录通过链式存储和去中心化的全球节点构成网络来解决账本修改问题。
(a) Misdirectional problems: Bitcoin acquisition can only be obtained through mining, with a total of 21 million bitcoins, which solves the problem of currency abuses in the distribution chain;
链式存储可以简单理解为：存储记录的块是一块连着一块的，形成一个链条；除第一个块的所有区块都的记录包含了前一区块的校验信息，改变任一区块的信息，都将导致后续区块校验出错。因为这种关联性，中间也无法插入其他块，所以修改已有记录是困难的。
Chain storage can be understood simply to mean that the blocks in which the records are stored are contiguous and form a chain; that all blocks except the first contain the verification information of the previous block, and that changing the information of any block will lead to errors in the subsequent block. Because of this correlation, no other blocks can be inserted in the middle, it is difficult to change the existing records.
而去中心化节点可以简单理解为：全球的中心节点都是平等的，都拥有一模一样的账本，所以，任一节点出问题都不影响账本记录。而要修改账本，必须修改超过全球一半的节点才能完成；而这在目前看来几乎不可能。 既然账本无法修改，那要是记账的时候作弊呢？ 首先，比特币的每条交易记录是有私钥签名的，别人伪造不了这个记录。你能修改的仅仅自己发起的交易记录。
Decentralizing nodes can simply be understood as: the central nodes of the world are equal and have the exact same books of accounts, so any one-point problem does not affect the records of the accounts. To change the books, more than half of the world’s nodes have to be changed; this is almost impossible at present.
其次，是关于记账权问题：比特币的记账权，通过工作量证明获得，可以简单理解为：通过算法确定同一时刻，全球只有一个节点获得了记账权，基本规律是谁拥有的计算资源越多，谁获得记账权的概率越大，只有超过全网一半的算力，才可能实现双花。
Secondly, on the issue of rights to bookkeeping: Bitcoin's rights, obtained through workload proof, can be understood simply as: by determining the same moment through algorithms, only one node across the globe is given rights to bookkeeping. The more the basic rule is who owns more computing resources, the more likely it is that who gets rights to bookkeeping, the more likely it will be that only half the computing power of the whole network will make it possible to achieve double flowers.
备注：比特币的模式是不可复制的，比特币已经吸引了全球绝大多数的算力，从而降低51%攻击发生等问题；其他的复制品基本无法获得相应的算力保证。
Note: The Bitcoin model is not replicable, and Bitcoin has attracted the vast majority of global computing power, thereby reducing problems such as 51 per cent of attacks; other replicas are largely unable to secure the corresponding weight.
目前，比特币还存在着51%和效率低等问题有待解决，另外，关于交易本身的信任问题是个社会问题，比特币是没有解决的，也解决不了的。
At present, there are still problems of 51 per cent and inefficiency in Bitcoin, and trust in the transaction itself is a social problem that cannot be solved by Bitcoin.
3、应用案例
最具代表性的当然是比特币，也不用多说了。
The most representative of all, of course, is Bitcoin.
备注：代币这块真的不看好，比特币目前吸引了全球绝大部分的算力，有独一无二的算力资源作为支撑还稍好一点，其他的代币和传统的货币相比，其背后缺乏国家和武力为其做信用背书，且夺取了国家发币带来的各种好处（如宏观调控），仔细想想就知道有多不靠谱。
Note: The currency is really bad. Bitcoin currently attracts most of the world's computing power, has a unique amount of numeracy to support it a bit better, and other currencies lack State and force to back them up with credit endorsements, and captures the benefits (e.g. macro-regulations) of a country's currency.
结论
区块链应用的场景肯定还有很多，但很多都还不大明朗，暂时就先梳理以上7种场景，顺便归纳一下。
There must be a lot of scenes for block chain applications, but many of them are not yet clear. For the time being, the seven scenes are sorted out and summarized by way of example.
区块链这么火，但实际应用的案例却少之又少；我认为，并非区块链技术目前存在的问题阻碍了其大范围的应用，也不是区块链可以应用的场景非常少，区块链商用牵扯到各方的利益，其最大的难题可能远在技术之外。
Block chains are so hot, but there have been few examples of actual applications; I believe that it is not the current problem of block chain technology that hinders their wider application, nor are there very few scenes in which they can be applied, and that they are commercially relevant to the interests of all parties, and that the greatest challenge is likely to be far from technology.
