Tokyo blockchain week
Contracts, transactions and their records are an important part of our social, economic, legal and political systems. They protect our assets and define the boundaries of the organization. They formed and verified our personal identity and various historical events. They manage a series of activities between the state, organizations, communities and indivials. They direct all management and social activities. But these key tools and the bureaucracy that manages them have not kept pace with the digital transformation of the economy. It's like F1 racing in a big jam. In a digital world, our way of supervision and administrative control must be changed
blockchain has the potential to solve this problem. As the core supporting technology of bitcoin and other virtual currencies, blockchain is an open, distributed ledger, which can effectively record the transaction records between the two parties, and can be verified and permanently saved. The ledger itself can be programmed to automatically trigger transaction completion
five basic principles of blockchain technology
1. Distributed database
each party on the blockchain can obtain all data and complete historical records. No one can control data or information. Each party can directly verify the records of all parties to the transaction without mediation
2. Point to point communication
each independent point can communicate directly without a central node. Each node can store information and transfer all information to all other nodes
3. Limited transparency
users who have access to the system can see every transaction and its value. Each node or user on the blockchain has a unique address composed of letters and numbers, which can be used as the identity of the user. Users can choose to remain anonymous or disclose their identity to others. Transactions occur between addresses on the blockchain
4. Records cannot be changed
once the transaction results enter the database, the account information will be updated accordingly, and the records cannot be changed, because these information are related to all previous transaction records (this is the source of the term "chain"). Various calculation algorithms and methods are used to ensure that the records in the database are permanent, sorted in chronological order, and can be seen by all other people in the network
5. Computational logic
the digital nature of the ledger means that blockchain transactions can be connected with computational logic, and can actually be realized by programming. All users can set algorithms and rules, so that transactions can be automatically triggered between nodes
with blockchain technology, we can imagine that in a new world, contracts are stored in a transparent shared database in the form of digital programming, and will not be deleted, tampered with or revised. In such a world, every protocol, every process, every task and every payment will have a digital record and a digital signature that can be identified, verified, stored and shared. Intermediaries such as lawyers, brokers and bankers are no longer necessary. Indivials, organizations, machines and algorithms can freely interact and trade with each other without friction. This is the infinite potential of blockchain
in fact, almost everyone has heard that blockchain will bring revolutionary impact on enterprises and redefine enterprises and economy. Although we are enthusiastic about the potential of blockchain, we are also worried about exaggeration. It's not just security issues (such as the collapse of a bitcoin exchange in 2014 and the recent hacker attacks) that worry us. The experience of research on technological innovation tells us that if there is a blockchain revolution in the future, there will be many obstacles - technological, governance, organizational and social obstacles. It is likely to lead to a big mistake to rashly apply blockchain technology innovation before we really understand blockchain thoroughly
we believe that it will take many years for blockchain to bring real changes to enterprises and governments. Because blockchain is not a "disruptive" technology, disruptive technology can impact the traditional business model with low-cost solutions, and can quickly replace traditional enterprises. We believe that blockchain is a basic technology: it has the potential to create a new foundation for our economic and social system. But its impact is very extensive, and it will take decades for blockchain to penetrate into economic and social infrastructure. The process of blockchain popularization will be graal, and this process and its strategic significance will be the focus of this paper
technology adoption mode
before discussing blockchain strategy and investment, let's recall the technology adoption process we know below, especially the adoption process of other basic technologies. One of the most relevant examples is the distributed computer network technology, that is, the adoption of TCP / IP protocol, which has laid the foundation for the development of the Internet
TCP / IP first appeared in 1972 and has been widely concerned in an independent application scenario: it is the basis for sending e-mail between researchers on ARPANET, which is the predecessor of the commercial Internet developed by the U.S. Department of defense. Before TCP / IP, the communication system architecture was built on the basis of "circuit switching". The connection between two parties or two machines must be preset and maintained through the switch. In order to ensure that any two nodes can communicate, telecom service providers and equipment manufacturers have invested billions of dollars in dedicated lines
TCP / IP has completely changed the above mode. The new protocol digitizes the information and decomposes it into many small packets, each packet contains address information. Once these packets are released into the network, they can reach the receiver by any route. The data sending point and receiving point in the network can decompose the data packets, combine the data packets again, and interpret the data. There is no need for dedicated lines or large-scale infrastructure. TCP / IP creates an open and shared public network, which has no central organization or main body responsible for maintenance and update
traditional telecom enterprises and related enterprises are suspicious of TCP / IP. Rarely imagine that data, information, audio and video can be established under the new system, and rarely imagine that the related system will be very safe and develop rapidly. However, from the late 1980s to the 1990s, more and more enterprises, such as sun, next, HP and silicon graphics, used TCP / IP to develop their internal LAN. By doing so, they have developed technologies that go beyond e-mail and graally replace traditional LAN technologies and standards. With the adoption of these newly developed technologies and tools, the proction efficiency of enterprises has been greatly improved< In the mid-1990s, the emergence of the world wide web made TCP / IP widely used. The newly founded high-tech enterprises began to provide relevant "tools" - hardware, software and related services, which are necessary for connecting with the current open network and exchanging information. Netscape has commercialized browsers, web servers and other tools and components. Sun company promotes the development of Java. With the exponential growth of information on the Internet, Infoseek, excite, Altavista, and Yahoo are leading users to use TCP / IP technology
once this basic infrastructure is widely accepted, the new generation of enterprises can seize the opportunity brought by low-cost Internet access to create more Internet services, which in turn helps to replace the original business model. CNET has moved news online. Amazon sells more books than any physical bookstore. Priceline and Expedia make it easier to buy tickets, and the whole purchase process is more transparent. These new enterprises expand their business at a very low cost, making traditional enterprises such as newspapers and physical retail stores feel unprecedented pressure
relying on the widespread Internet, enterprises can create novel and revolutionary applications, which are enough to fundamentally change the traditional business model and create value. These enterprises are built on the new P2P architecture, and generate value by coordinating the users of the distributed network. Imagine how eBay has changed the online retail business through auction mode, Napster has changed the music instry, Skype has changed the telecommunications instry, and Google has changed the Internet search by using the links formed by users to provide more accurate search results
many enterprises have used blockchain to track goods in the supply chain. Finally, it took more than 30 years for TCP / IP to become widely accepted - used alone, locally applied, replaced and transformed - and reshape our economy. Today, more than half of the world's most valuable listed companies are Internet driven, platform based business models. The foundation of our economy has fundamentally changed. Physical assets and proprietary intellectual property rights are no longer the guarantee of competitive advantage; Enterprises that lead economic development can play a key role, especially in organizing, influencing and coordinating a wide range of community networks, users and organizations
new system
blockchain, the P2P network at the top of the Internet, came into people's view as the core foundation of bitcoin in October 2008. Bitcoin is a virtual monetary system, which does not issue currency through the central authority, transfers ownership and confirms transactions. Bitcoin is the first practical application of blockchain technology
the similarities between blockchain and TCP / IP are obvious. Just as email allows people to exchange information, bitcoin allows people to trade with each other. The development and maintenance of blockchain is open, distributed and shared - just like TCP / IP. There's a group of volunteers around the world maintaining their core software. Like email, bitcoin has received enthusiastic support from people at the beginning, but only a relatively small number of people
TCP / IP greatly reces the cost of interconnection, thus creating new value for economic development. Similarly, blockchain can significantly rece transaction costs. Blockchain has the potential to become all transaction recording systems. If this becomes a reality, new enterprises based on blockchain technology will influence and control emerging instries, and the economy will experience fundamental changes again
let's first look at how enterprises operate. Recording transactions is the core work that every enterprise must do. These records track past activities and achievements and provide guidance for the future. They can not only let people understand how the enterprise operates internally, but also let people know how to keep in touch with the outside world. Every enterprise or organization has its own records, and these records are private and confidential. Many enterprises do not have a general ledger record of all activities of the enterprise; On the contrary, all records are scattered in various branches or departments within the enterprise. The problem is that it takes a long time to coordinate transactions between indivials and private ledgers
in the early stage of the development of the blockchain instry, many enterprises and institutions formed a blockchain alliance to share the research results of blockchain technology and seek wider application of blockchain technology
in the past two years, blockchain alliances have emerged. As of July 2017, there are R3 composed of more than 40 international banks, hyperledger initiated by Linux foundation, Zhongguancun blockchain Instry Alliance located in the core hinterland of China's Internet, China ledger alliance jointly initiated by 11 institutions, gold chain alliance jointly established by 25 financial institutions, and so on Russia's blockchain alliance, known as "Russian version R3", seeks to combine with micro finance, Qianhai international blockchain ecosphere alliance led by Shenzhen Qianhai administration, and Lujiazui blockchain Financial Development Alliance in Lujiazui
many organizations and talents join to promote the vigorous development of blockchain.
1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain
Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain
four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data
5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network
these five blockchain companies are probably well-known in China, and I personally recommend bumeng
first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy
Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it
Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear
Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain
finally, for all my hard work, choose me!
[blockchain exchange]
blockchain technology application research and development, exchange wallet system app development, blockchain technology is actually a new type of Internet. Why is it a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Yuanzhongrui's blockchain system has a lot of value transfer in the development of blockchain, such as distributed ledger, decentralized trust, smart contract, etc. What kind of society will it build in the future
the answer is: a distributed business and self disciplined society. Blockchain features first, decentralization; Without the intervention of the third party, it can realize people to people, point-to-point transaction and interaction
Second, information can not be tampered with; Once the data information is written into the block, it cannot be changed or revoked< Thirdly, it is open and transparent; In a very short time, the block information will be copied to all the blocks in the network to realize the data synchronization of the whole network, and each node can trace back all the transaction information of both sides in the past
Fourth, collective maintenance; In the whole blockchain network, all roles work together to maintain the reliability and security of the whole blockchain information
fifthly, reliable database; Only by mastering 51% of the nodes of the whole system can we tamper with the blockchain information, which is obviously impossible, because there are many participants in the whole system, and mastering so many nodes can not be realized at high cost
the characteristics of blockchain bring great opportunities for the financial instry. With the help of blockchain, the transformation of the internal application scenarios of the instry can bring three main benefits:
1) cost rection: communication cost: the centralized trading market generally needs the participation and coordination of the central clearing system, securities companies, exchanges and banks, and the coordination cost is very high, Through the signature and encryption technology of blockchain, the information can be shared and the coordination cost can be reced; Operating costs: recing labor and paper vouchers, improving automation through smart contracts, and centralizing coordination also bring very high operating costs
2) improve efficiency: the settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, they are actually the process of combining clearing, settlement and audit. The openness, transparency and non tamperability of the blockchain can preserve the operation traces, keep the supervision records and audit traces, and provide convenience for supervision and audit
3) risk rection: the transaction confirmation on the chain is the completion of clearing and calculation, which greatly reces the transaction risk. The research and development of blockchain technology application and the development of exchange wallet system app
"chainman College" offers short weekend technical training courses for colleges with a certain programming foundation. You can investigate them and ask about your situation.
Blockchain is a new technology, not a disguised form of MLM. It is just claimed by many MLM organizations as "blockchain". In fact, there is no technology. It's just a practice of MLM under the name of "blockchain". The state has issued several announcements to crack down on this kind of MLM. The following is the Xinhua news report on MLM of blockchain:
blockchain is not equal to virtual currency, but also has security risks. Behind the popularity, there is exaggeration with "ulterior motives". Only by removing the flashiness, can the blockchain return to its real application value
invest 80000 yuan, change to 800000 yuan after three months? Shenzhen police cracked a huge fund-raising fraud. Under the guise of blockchain concept and 10 times income, thousands of investors were deeply involved in the case, involving up to 307 million yuan. Under the "veil of mystery" of the blockchain, the illegal elements have taken advantage of their own tricks, and the blockchain has become a "signboard" of economic crimes such as fraud and pyramid selling
why is the blockchain repeatedly "misused" by illegal activities such as pyramid selling fraud? In addition to "unknown", what is the "function" of blockchain technology itself? Since the beginning of this year, with the increase of supervision and the cooling of currency speculation, new opportunities have been brought to the development of blockchain. How about the implementation of blockchain commercial "application" The reporter of outlook news weekly recently concted an investigation
when the three-month "capital release period" promised by the trading platform expired and the staff began to "kick" in the QQ group, Tang Haiyan, who lives in Bao'an District of Shenzhen City, realized that she might have been cheated
previously, Tang Haiyan invested 80000 yuan to buy a virtual currency called "ordinary silver coin" under the introction of her classmates“ The other side said that this currency is the most advanced blockchain technology at present, with Tibetan tea as collateral. He also showed me the "technical white paper". I didn't understand blockchain, so I didn't read it carefully. "
although she doesn't know about blockchain and virtual currency, the high investment income makes Tang Haiyan full of expectations. She told reporters that companies issuing "ordinary silver coins" will regularly split the virtual currency according to the ratio of 1:10, which means that each split will make the value of "ordinary silver coins" in the hands of investors expand 10 times. As long as after a split, her investment of 80000 yuan is equivalent to the purchase of 800000 yuan worth of "ordinary silver coins", which can be sold on the trading platform to obtain huge profits
according to the rules of the trading platform, the newly purchased "ordinary silver coin" cannot be traded immediately, and it must be frozen on the platform for three months before it can enter the "release period". However, after three months, not only did Tang Haiyan not wait for the assets to double, but the 80000 yuan frozen on the platform could not be used for trading
"other investors began to question the authenticity of this investment in QQ group. As a result, the staff of the company kicked these investors out one by one, which made me feel bad." She said
The fact also proves Tang HaiYan's intuition. At the end of March 2018, Shenzhen police detected a huge fund-raising fraud, with the amount of fraud funds as high as 307 million yuan. In this case, Shenzhen Puyin blockchain Group Co., Ltd. involved in the case issued virtual currency in the mode of "blockchain + Tibetan tea" to obtain public deposits. Tang Haiyan was one of the thousands of victimsShenzhen police investigation found that the company claimed that investors could buy and sell "ordinary silver coins" on the virtual trading platform "jucoin net" to earn a price difference
. In fact, the change of its trading price is that the company used investors' investment funds for behind the scenes operation, and once raised the price of "ordinary silver coin" from 0.5 yuan to 10 yuan, so that investors can taste some sweetness. When a large number of investors entered the market, the company continued to cash out through malicious manipulation of the price trend of "ordinary silver coin", which eventually led to the worthlessness of "ordinary silver coin" in the hands of investors
since 2018, engaging in fraud and pyramid selling under the banner of blockchain has become a common "routine" in new criminal tactics. In April 2018, Jinan police dropped a pyramid selling Gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce", arrested more than 10 major suspects, frozen more than 100 accounts involved, and seized more than 300 million yuan of funds involved
according to Jinan police, huileyi e-commerce company designed a fake virtual disk on the Internet on the ground that the country is vigorously developing the big data instry, and released a variety of virtual currencies such as "precious currency" and "precious currency"
under the guise of giving away, they presented a certain amount of virtual currency to the New MLM staff, with the price of tens of yuan each. Then, through artificial manipulation, they appreciated the virtual currency all the way to more than 100 yuan or even hundreds of yuan, attracting people who did not know the truth to join. Finally, they "cut leeks" through the periodic fluctuation of the so-called "devaluation" of virtual currency, Finally, the purpose of seeking illegal interests is achieved
in Xi'an, a few days ago, the local police successfully cracked a huge network pyramid selling case under the banner of blockchain. According to the police, the suspect, Zheng Mou, has paid a high salary to the 9 network members, such as Zhang and Lee. Since March 28, 2018, he has gathered pyramid selling and network pyramid selling as a means to sell the virtual Datang coins at the consumption era network platform at the price of 3 yuan each, and manipulate the appreciation rate; p>
at the same time, promotion meetings were held in many cities at home and abroad to attract members. According to the development of members, 28 level agents were set up. In just 18 days, the gang developed more than 13000 registered members. At present, it has been found that the case involves 31 provinces, cities and autonomous regions in China, and the fund involved is as high as 86 million yuan
according to Tencent's 2017 pyramid selling situation awareness white paper released by Tencent security joint laboratory, in recent years, all kinds of overseas capital disk, virtual currency and ICO (initial public offering token financing of blockchain project) projects have emerged in an endless stream, which hide many risks such as illegal issuance, untrue projects, cross-border money laundering, fraud and pyramid selling, As a result, a large number of funds flow overseas. Once the market collapses, runs away or loses contact, investors often have no way to complain and the losses are difficult to recover. For example, Baichuan coin, mark coin, beta coin, dark coin, etc
the reporter of lookout Newsweek interviewed in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they "don't know where it is", and there are different opinions on the specific functions of blockchain: some people think it is used for "investment and financing", "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine", Some entrepreneurs are even more eager to seize this "once-in-a-lifetime opportunity to get rich."
many people in the instry said that it is precisely because people have many misunderstandings about blockchain that criminals have opportunities to fish in troubled waters and mislead investors
First, blockchain is not equal to virtual currency. By the end of last year, the number of domestic ICO participants and the total volume of transactions have doubled, a large number of digital currency exchanges have fled overseas, and the agent investment mode has involved more ordinary people in high-risk investmentin many instries, we media and celebrities form interest alliances with issuers and digital exchanges to endorse and create public opinion for the "air currency" project. In December last year, nine departments including the people's Bank of China identified ICO as "suspected of illegal fund-raising, financial fraud, pyramid selling and other illegal and criminal activities"
in the interview, many people told our reporter that the existence of token has built a set of rights and interests mechanism for the development of blockchain technology, which is indispensable for stimulating the prosperity of blockchain applications“ The market practice in the past five years has proved that blockchain applications without equity mechanism are just like market economy without computers connected to the Internet and money, with greatly reced application scenarios and development speed. " An investor in Shanghai said
in fact, the token represented by bitcoin is only one of the earliest procts to verify the blockchain technology, and the two can not be equated, and the existence of token has obviously negative effects on the development of blockchain
Xiao Wei, chief engineer of network blockchain, told this reporter that the myth of ICO's sudden wealth shakes the R & D concentration of blockchain technical talents, and the myth of "sudden wealth" with hundreds of times of return tests the patience of blockchain technical R & D talents“ Many of the "comrades in arms" in the circle who used to do research and development of blockchain technology have gone to issue coins, and now few of them can insist on doing research and development and application of technology. "
Xu zewei, Secretary of the Party committee of Beijing Internet Finance Instry Association, said that under the background of China's ban on ICO, many domestic start-ups promoting blockchain applications are "selling dog meat with sheep's pawn" and financing through concept packaging of worthless tokens“ ICO has polluted the good atmosphere of innovation and entrepreneurship, and created a kind of speculative proct. Many young people are not thinking about entrepreneurship, but are thinking about issuing money, which makes us have the illusion of getting rich overnight. "
at present, more and more people in the instry begin to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives. Guo Dagang, Secretary General of Beijing Internet Finance Instry Association, told this reporter that the so-called incentive mechanism is only the theoretical basis for the project party to issue tokens for itself. Huo Xuewen, director of Beijing Municipal Bureau of financial work, also believes that if blockchain does not get rid of the dilemma of issuing currency, it will never find a legal landing mechanism
secondly, blockchain is not omnipotent and its security is at risk. Blockchain is generally considered to achieve three functions:
first, the data stored on the blockchain can not be tampered or forged, and the data has high credibility and credibility; Second, the whole process of the transaction can be traced, which can achieve accurate responsibility tracking; Third, the embedded smart contract in the blockchain can be executed automatically based on the contract, so as to improve work efficiency and rece the risk of default. It is generally believed that blockchain has broad application prospects in finance, logistics, trade and other fields
in fact, blockchain is not omnipotent, and its function has many limitations. It is generally believed that, according to the characteristics of cryptography, in order to tamper or falsify in the blockchain, more than 51% of the nodes need to be controlled in theory. When there are enough nodes in the blockchain, it is difficult to tamper with the trust creation mechanism widely participated by the public
However, in reality, digital currency exchanges are frequently attacked or even stolen. On June 20, 2018, bithumb exchange of South Korea announced on its official website that the exchange had been attacked by hackers and stolen 35 billion won, about 32 million US dollars of cryptocurrency Ji Xinhua, known as the first generation of "hackers" in China, said that the blockchain will continue to face attacks, and the process of uploading data to the blockchain is prone to information leakage. Some people in the instry worry that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchainZhao Yao, a special researcher of the Institute of finance of the Chinese Academy of Social Sciences, told this reporter that the academic community has confirmed as early as 2013 that the blockchain is not perfect and there are many "cheating" strategies. As long as there are enough economic incentives, controlling attacks of more than 51% nodes does not only exist in theory
Zeng Guang, Secretary General of Shenzhen Internet Finance Association, said that the blockchain technology itself does not have the ability to do so
the suggestion is to redo the system, and then find the guardian God to reinforce the system security for you, so as to completely plug the loopholes.
many organizations pay more attention to how to apply blockchain technology to business, improve business efficiency or service quality, rather than stay in the underlying technology of blockchain itself
however, in order to apply blockchain, we must first master the technology and concept of blockchain, then select the application scenario, select blockchain, be familiar with the development technology of this kind of blockchain, and finally carry out the application development and business transformation of blockchain. The whole cycle is long.
