How do lawyers view blockchain

1. Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain<

Yu Kequn, director of the national information technology security research center, pointed out that for privacy exposure, data leakage, information tampering, network fraud and other issues, the emergence of blockchain has brought a lot of expectations to people. However, there are still many challenges in the security of blockchain

Yu Kequn said that at present, the blockchain is still in the primary stage, and there are many challenges such as the security of cryptographic algorithm, protocol security, use security, system security and so on

Yan Hanbing, director of the operation Department of the national Internet Emergency Center, also pointed out that if blockchain wants to occupy an important position in the global economy, it must first solve the security problems it faces

Yan Hanbing pointed out that blockchain security issues include many aspects. For example, traditional security issues, including the protection of private key, including the traditional vulnerabilities of application layer software. In addition, there are some loopholes in the new protocol

the data provided by the decentralized vulnerability platform (DVP) also shows the seriousness of blockchain security issues. Wu Jia, head of DVP, revealed that in the week since July 24, DVP has received 312 vulnerabilities from white hat, involving 175 project parties. Including smart contracts, well-known public chains, exchanges and a series of other projects. There are 122 high-risk vulnerabilities, accounting for 39.1% of all vulnerabilities, and 53 medium risk vulnerabilities, accounting for 17% of all vulnerabilities

Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, usage, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples

it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face

Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of software and hardware related to the blockchain, and there are a lot of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of relevant security employees is scattered, and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges.

2. 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.

3. At present, there are no laws and regulations on blockchain. After all, it is a new thing, and the formulation of laws and regulations will always lag behind the development of economy, society and technology, just like the legislation after the development of e-commerce for more than ten years.

4. 1) First of all, it defines the technical value and positioning of the blockchain. As I said at the beginning, the positioning of the blockchain should take the blockchain as an important breakthrough for core technology and independent innovation
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

5.

Using blockchain technology to store and issue electronic evidence is the basis of the application of blockchain technology in the legal field

in the whole life cycle of electronic data generation, collection, transmission and storage, blockchain technology can protect electronic data, prevent tampering, and leave traces of data operation

using blockchain technology to preserve electronic evidence, the electronic data that needs to be deposited is recorded in the form of transaction, stamped with time stamp, and recorded in the block, so as to complete the process of data preservation and deposit. In the process of data storage, multiple participant nodes witness together and maintain a distributed ledger, which greatly reces the possibility of data loss, tampering and attack

the combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve litigation efficiency

6. At present, there is no special law. You need a lawyer to give you a legal opinion
what is a legal opinion? In fact, legal opinions are a general term. They actually include four aspects
1. White paper compliance
2. Token non securitization certification compliance
3. Private placement terms compliance
4. Public offering compliance
mainly focuses on these four aspects

8. Brother, you're kidding. How loud is that? Do you know

9. We need to look at the mining income according to the model of the graphics card, and then use the income to look back at the cost time. If it is a low-end graphics card, it may not be able to be found in my life

10. Blockchain technology is still in the exploratory stage, which has a non tamperable and open and transparent nature, and can be better combined with the law
