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 the emergence of blockchain has brought people a lot of expectations for privacy exposure, data leakage, information tampering, network fraud and other issues. However, there are still many challenges in the security of blockchain 
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, use, 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 the software and hardware related to the blockchain and a large number of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of the 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. 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

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. With the development of blockchain, there are more and more ICO projects and exchanges in the blockchain instry. How should so many projects develop in compliance
the current blockchain project compliance is divided into two sections:
first, blockchain coin issuing project compliance: Foundation + legal compliance opinion
often referred to as ICO, IEO, etc. first of all, we build overseas entities. Generally speaking, most coin issuing entities choose Singapore foundation. It is a non-profit company in the form of XX Foundation Ltd. Finally, a legal compliance opinion is issued by a Singapore lawyer. The content of the legal opinion includes the amendment of a white paper and the token non securitization certificate, which is mainly to make the project comply with the laws of Singapore. This legal opinion is also needed for the later docking of the project with the currency on the exchange< Second, blockchain exchange project compliance: subject company + digital currency trading license:
license is one of the important compliance documents of the platform. It is equivalent to a business license. In particular, after Huoyuan won the Japanese license, the US license and applied for the Canadian license, the license was pushed to a new height. Obtaining the US MSB license also means that the company can reasonably conct business in most states of the United States. This is the reason why the major platforms have started to apply for licenses. If they want to carry out business formally and legally, they have to apply for licenses
for example: MSB digital currency exchange license in the United States, MTR digital currency + Wallet al license in Estonia, austrac digital currency license in Australia, etc
the role of MSB license in the United States:
1. American MSB license is famous, packaging platform and good publicity
2
3. It can increase the trust of customers, enhance their visibility, and make the platform develop better and faster in compliance
advantages of MSB license
1. Investor recognition - Corporate Law and financial instry regulation in the United States are very perfect. With a U.S. license, your digital currency trading platform will be more recognized by global investors
2. Get authoritative approval - with the authoritative approval of the U.S. Treasury Department, you can carry out relevant business in the United States and around the world, which represents the compliance supervision of digital currency platform
3. Become a first-line platform -- MSB license is also a standard license for global digital currency trading institutions. Coinbase, bitfinex, poloiex, hotcoin.com, OK, coin security exchange and other platforms all hold this license to operate
4. Diversified services - MSB license allows currency exchange and delivery services, so that you can better meet customer needs and provide more diversified services
why is the license so important for the trading platform? First of all, people in the traditional foreign exchange circle know that the foreign exchange platform has the importance of supervising the license. Even such a traditional mode will create a future trading platform. Therefore, the license plate is bound to become a trend of development

5. Domestic blockchain projects are still relatively conservative. Blockchain projects always involve a derivative instry, that is, digital currency transactions. If domestic projects are not allowed, what should we do? You can register a non-profit foundation in Singapore and add relevant legal opinions to prove that the project you are doing does not violate the current laws and regulations of Singapore, such as Biyuan chain and Leyte coin
after registering the main body of the foundation, we still need to do later legal compliance, the main purpose is to draw a clear line between law and crime, but I said it doesn't count. Because digital token is indispensable for blockchain. To put it bluntly, digital currency drives the popularization of blockchain in China, but what's the fact? Digital currency is just a small application of blockchain technology
e to the particularity of the instry, At present, there are no formal laws and regulations to restrict its development, involving a wide range of violations:
pyramid selling
illegal fund-raising
money laundering
absorbing public deposits
illegal operation
transnational foreign exchange crimes
providing more convenience for terrorist financing
therefore, different countries in the world have different attitudes towards blockchain, and China is explicitly prohibited, So we all go overseas to develop projects, such as Singapore and Thailand. First, the local laws and regulations are required. Who has the final say in the matter of whether the project is legal? There are two ways: to apply for a formal digital transaction license or to rely on a legal opinion issued by a lawyer. At present, the latter is in the majority, easy to operate and low cost.

6. Mainly depends on the operation content and project
the application of blockchain technology itself is not illegal. At present, ant financial services, Tencent and network all have blockchain technology support

7. You are right. The spring tide will come soon. Give me some time. In addition, it's not good to participate in the blockchain project. Let's have a look
8. An example of a white paper that I think is well written: penta (known as "Fanta network" or "pnt") is the underlying basic chain and protocol of the next generation of blockchain value Internet. It aims to realize three connections (chain to chain connection, chain to centralization connection, and chain to chain value connection) based on five dimensions (subject, trust, value, circulation and scenario), For this purpose, we have formulated specific 10 core technology routes to make the blockchain world interconnected and inclusive. The main content is divided into four parts: first, the philosophical basis of Fanta network; second, the connection of five dimensions; third, the interaction of the world; fourth, the application field.
