Japan's blockchain policy

2. There are several entry points to look at: top-down policy support, credible blockchain data sharing, token and digital currency on blockchain. At present, in 2020, the blockchain instry is at an inflection point from barbaric growth to standardized operation and development, And the epidemic will also serve as one of the catalysts to promote the implementation of blockchain in the instry faster.

3. Blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

4. Now it has entered the era of digital currency. In recent years, digital currency is very popular. For example, blockchain is the focus of people's attention. Now more and more people begin to pay attention to blockchain. Many people are concerned about blockchain's entry into China's market. Domestic policies have not explained blockchain in detail. Many people are worried about whether blockchain is legal? Is blockchain legal in China? Xiaobian, let's explain the blockchain in detail

on April 9, 2017, Hangzhou municipal government and a company jointly set up a $10 billion xiongan global blockchain innovation fund, which can promote the development of blockchain projects. This initiative has also attracted the attention of many relevant financial people. At present, Hangzhou blockchain Instrial Park is one of the important initiatives funded and developed by the municipal government, I believe this case has also become one of the representative cases in China. Since then, more and more blockchains have developed all over the country<

at present, China has a new understanding of digital currency, analyzing the value of digital currency in essence, and relevant departments are also actively participating in the corresponding research. The central bank has set up a special research group and digital currency Research Institute, hoping to further explore the digitalization of sovereign currency. From the side, it can be seen that China has a positive attitude towards blockchain technology, and the Chinese government has repeatedly stressed the important role of blockchain technology in reshaping the global financial pattern

with the development of global economy, the Chinese government has realized the commercial development of domestic blockchain projects. From the blockchain projects invested by Hangzhou municipal government, it can be seen that more and more provinces will start to carry out blockchain projects in the future, which can promote the development of local economy

is blockchain legal in China? At present, the Chinese government is actively studying blockchain, and has carried out blockchain related projects in some provinces. Through the above introction, I believe that people should have a certain understanding of the blockchain. I believe that in the near future, there will be more and more blockchain projects, which can promote the development of domestic economy and enable more and more people to get more wealth from blockchain projects.

5. China's local policies have been introced, which series of related policies? This is not very clear. Is this a national document?

6. Nothing else, because it's not against cryptocurrency. Can register fund, can open exchange
as an international financial center, it will not oppose any currency, even the virtual cryptocurrency
this feature also occurs in Hong Kong, the United States, Japan and other areas with relatively open finance. The more open the finance is, the more tolerant the virtual currency is.

7. Yes, since the central government emphasized that the blockchain should be regarded as an important breakthrough for independent innovation of core technology and accelerated the development of blockchain technology and instry innovation, many places have issued relevant policies to seize the air of blockchain instry. If you want to know more about blockchain, you can pay attention to huocoin University, which also has online live classes.

8. As a mechanism of allocating social resources, law is determined by the objective requirements of social and economic development and directly affects the whole process of economic operation. It can simplify the complexity of social relations, save transaction costs, and help social members conct transactions safely, normatively and orderly
based on the legal framework, the blockchain technology makes the transaction information more secure and transparent, and the data more traceable through the pre-set automatic execution of intelligent contracts, which greatly reces the cost of law enforcement, presents the situation that the law and technology complement each other, and the law and economy are integrated, which makes the legal constraints and enforcement graally move towards intelligence
what is blockchain
blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era
blockchain is essentially a decentralized distributed ledger database. It is a series of data blocks associated with cryptography. Each data block contains the information of effective confirmation of multiple bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
foreign legal regulations on blockchain
as the blockchain technology itself is still in the exploration stage and has not been applied on a large scale, only some countries have enacted special legislation on blockchain technology< In the United States, Vermont and Arizona have passed bills to clearly define and support blockchain technology for public use. The bill stipulates the use specifications of blockchain and smart contract, and states that all data related to blockchain are "considered as electronic format and become electronic records", which is recognized by the state
UK
distributed ledger Technology: beyond blockchain mentions that the UK federal government will invest in blockchain technology to analyze the potential of blockchain application in traditional financial instry
Singapore
the government supports financial technology enterprises such as blockchain technology, and has launched a regulatory sandbox to provide a more tolerant development environment for blockchain start-ups
China's legal regulation on blockchain
in addition to the above-mentioned policies on blockchain itself, a series of regulatory provisions have been issued internationally for virtual currencies such as bitcoin
in our country, in addition to the policies on the transaction and financing of bitcoin and other virtual currencies, the government has also issued many policy regulations on blockchain
on December 27, 2016, blockchain technology was listed in the notice of the State Council on printing and distributing the 13th five year plan for national informatization. At the same time, the State Council also issued a document "China's blockchain instry is expected to walk in the forefront of the world" to support the healthy development of blockchain
it is mentioned in the guidance of the general office of the State Council on actively promoting the innovation and application of supply chain that we should study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on supply chain. Promote the organic docking of various supply chain platforms, and strengthen the disclosure and sharing of credit rating, credit record, risk warning, illegal and dishonest behavior and other information< In the eyes of lawyers, the legal risks of blockchain technology
as a distributed system, blockchain is an innovative application in the field of technology. According to the current exploration results, its technical concept can bring great changes to the development of various instries
however, as the law has not yet issued clear instry standards and applicable norms for blockchain, there are still problems such as national supervision and legal regulation in the future
taking bitcoin as a typical digital currency as an example, the first problem we face is supervision. Bitcoin and other digital currencies based on blockchain technology are logically decentralized and opposed to centralized supervision
secondly, the application of blockchain technology has to face huge risks. Taking bitcoin as an example, loss, theft, attack, speculation, money laundering and all kinds of disturbances, doubts and events have been accompanied by the development of bitcoin
the wide application of blockchain technology is inseparable from smart contract, which defines commitment in the form of digital coding. The two sides of the transaction do not need to trust each other, all transactions are enforced by the code
however, the validity of the form and content of smart contract has not been formally recognized by the law and the judiciary. As the contract text in the form of digital coding, it is not clear whether it can constitute the elements of an effective contract and whether it can meet the authenticity, legality and validity of the evidence to be accepted by the judiciary
e to the decentralized nature of blockchain technology, its own rules are bound to conflict and contradict with social rules and national legal rules. It is precisely conflicts and contradictions, risks and problems that can stimulate motivation and imagination, including that of society, the state and indivials
in the process of transaction, virtual currency based on the application of blockchain technology has posed great challenges to the legal tender and financial system of various countries, and caused investment risks and even social problems.

9. The application of blockchain finance is the key field that it plays a role in reality. The financial instry needs such high-end technology, and the traditional mode of operation will have profound changes because of such technology. The application of blockchain finance has many distinctive characteristics, which makes people talk about it with relish. Moreover, it attracts people's attention because of the actual effect, which has a growing impact

Abstract: developed countries and technology companies have been ahead in the research and application of blockchain technology. From the perspective of patent application, there may be a gap of about one and a half years between China and the United States in terms of blockchain technology. Based on the above situation, how can China achieve "asymmetric" catch-up? First of all, we should see the situation clearly, seize the opportunity and meet the challenge. Secondly, after understanding the necessity of building the bottom layer of the blockchain for the existing business and future development of the financial instry, a consensus of "China's financial blockchain alliance" was reached among financial enterprises. Finally, we should work together to meet the change

how to understand blockchain

bitcoin: a peer-to-peer e-cash system. In 2009, after the paper was published, bitcoin was born as a virtual currency in the digital world of the Internet. At present, bitcoin's total market value is about US $6.5 billion. Although its market value is constantly changing, it is still the largest virtual currency in the world

another important concept is blockchain. Blockchain is an underlying technology of bitcoin, and bitcoin is only an application of blockchain. As we all know, bitcoin can achieve point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology

at present, there are several misunderstandings about blockchain. Blockchain can be described in English as "decentralized blockchain", in which decentralized is translated as "decentralized". However, I think that the blockchain has realized the value dissemination without intermediary, that is, the point-to-point value dissemination. This does not mean that after entering the era of blockchain, there is no need for the center, but it should develop from a single centralization to the parallel between centers. Then, the existing center is likely to become a sub center or weak center. At present, all banks have their own data centers. If the financial blockchain alliance is established in the future, they can become the nodes in the blockchain alliance, so the blockchain does not need a center<

blockchain does not need credit

we often see some articles that think that blockchain is to "de credit". In fact, blockchain is to build trust through consensus algorithm and ensure the correctness of transactions through consensus among nodes. Build trust with low cost through mathematics and algorithm, rather than "de credit". However, the digital asset transaction between people does not need two people to know each other, or trust each other, and does not need a third-party credit institution. It only needs everyone to trust the trusted network of blockchain

why is it credible? Because it is a distributed database, there is a set of consensus based mechanism: a set of encryption algorithm, making it tamperable. On the one hand, the public key makes the information transparent and traceable; On the other hand, private key can protect privacy

blockchain is not a mature technology, nor is it omnipotent. At present, blockchain technology is still in the early stage of development. At the beginning of this year, we sent a delegation to study in the blockchain Research Laboratory of Barclays in South Africa. At the seminar, experts on the African blockchain of Barclays believed that it would take at least five to ten years for the blockchain technology to become a truly mature technology. At present, blockchain has the disadvantages of relatively slow computing speed and small storage space, and not all data processing needs to use blockchain

the research and application of blockchain in foreign countries

we find that the old financial developed countries have been ahead in the research of blockchain technology. The British government believes that it is very important for the government to participate in the legislation of digital currency and blockchain network, and encourages in-depth research on blockchain technology. The UK government is actively evaluating the potential of blockchain technology and considering using it to rece financial fraud and cost. In addition, the UK government plans to develop applications that can be used between the government and public institutions

in February this year, the European Commission put crypto digital currency at the top of the fast development target area, which promoted the policy research of various institutions on digital currency. Technology companies are also ahead in the research of blockchain technology

IBM launched the "open ledger project" to develop enterprise level blockchain software structure, promote the commercial use of blockchain technology, and support the docking of external data through the bluemix and API infrastructure of IBM cloud computing platform. IBM still has a lot of practice in blockchain technology. Recently, it and a South Korean company have made creative experiments using blockchain technology and Internet of things, and achieved some results

Microsoft uses Azure Platform to provide users with "blockchain as a service", which enables R3 and its bank members to speed up the process of experiment and learning, and accelerate the development, testing and deployment of distributed accounts

Intel also released sawtoothlake, an efficient molar platform for building, deploying and running distributed ledger; At the same time, Intel also studies to create a trusted execution environment for hardware chips of blockchain applications, providing higher security and privacy< At the same time, Wall Street is taking positive actions. Although it was established relatively late, the core function of R3 is to formulate instry standards for the development of banking blockchain technology, explore practical uses, and establish banking blockchain alliance

from what we know, in addition to these two new companies catering to the arrival of digital finance era, large financial institutions are studying blockchain technology and building their own blockchain concept and technical team

at present, there are practical application cases of blockchain technology

in Canada, blockchain start-up blockchain Tech Ltd has been listed on the growth enterprise market of Toronto Stock Exchange; The Estonian government will launch the government's blockchain healthcare record

domestic attention and Research on blockchain technology

blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant departments also expressed their support for blockchain application research last year

from the perspective of enterprises, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge

in addition, a number of instry alliances are being established. In terms of financial institutions, the cases of blockchain application by large banks and financial institutions in China still need to be solved
by the end of 2015, Bank of America had obtained 15 patents on blockchain. There may be a gap of about a year and a half between China and the United States in blockchain technology
the application of blockchain finance is entering a new stage in an all-round way, various applications will be more and more in-depth, and the relevant changes will be more and more attention, and a great new trend will be formed.

10. Hunan Province, Changsha City and the high tech Zone have issued relevant policies. In particular, the high tech Zone has also initiated the construction of the SMIC blockchain platform project, which is aimed at collecting information from tens of thousands of enterprises in Changsha high tech Zone.
