Blockchain related risks

1. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.

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 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

3. There must be risks, and they are high risks, because high returns are always bound with high risks. You are a little rookie who doesn't know anything. Can you make money like other people's old birds? If you are just interested in the coin circle, I suggest you don't be reluctant to spend a small amount of money to add a pay circle of the coin circle. For example, the group of Li Xiaolai, the big money in the coin circle, once cost as much as 5 million yuan. There are also some old cats and baoerye groups, but they are too far away from us ordinary people. But if you have a lot of money, it's a good deal. If it's only tens of thousands, it's suggested to add some groups with high cost performance, such as the payment group of fire chain blockchain, Zhongshen blockchain club, which are reliable, and there is a free trial period.

4. Forget the private key, the mnemonic note lost... This is the most basic. When it comes to the essence of investment, it is the investment risk caused by the fluctuation of currency price. GRE global risk trading all specialized insurance can be bought to avoid the risk of digital money market.

5. How much risk you can take and how much you will get in return. Just like in troubled times, people who rise up may fall to the ground or become the next emperor. The question is, do you dare@ Block chain God Tucao: make complaints about investment risks correctly.

6. Yes, blockchain is a high-risk project.

7. You mean digital currency? Digital currency based on blockchain technology has good performance in operation security, but it also exposes many problems. Most governments are cautious or resistant to the current non legal digital currency, and the research on legal digital currency continues to improve. The main risk is that there is no commercial application foundation and it can't be realized. Honghua coin has done a good job in this aspect. He has cooperated with Chinese people all over the world to realize the decentralization of enterprises, so we can learn more about it.

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

The risk of any investment is directly proportional to the return. The key is whether you dare to participate in it. Of course, there are too many uncertainties in the current blockchain instry, not because of the instability of technology, but more because some insatiable people are black hearted and hard to defend

in my opinion, bitcoin is the most popular blockchain derivative currency at present, and there is no one. Then there are many other counterfeit currencies. If you hold some bitcoin now, but you are short of bitcoin, it is equivalent to a risk. And you are facing this risk. In the normal way, you can hardly short bitcoin to make profits, unless you do some up and down options to hedge the risk. I have done some short-term options in extreme NEW Europe, Long term options are not recommended, and few platforms can. Bitcoin doesn't operate in the same way as foreign exchange, so it has profit opportunities. When you are bullish, you can buy or hold money. When you are bearish, you can throw money. When you hold money, you can only hedge it by buying options, so the risk is relatively high

according to the current bitcoin market, if this position is at the bottom again at most, it will hit the top edge of the box. In short, this range fluctuation will increase. If there is a wait-and-see, you can wait until you fall to the bottom of the box and try to buy it. You must set a stop loss, or you will be confused when you are buried. If you think bitcoin is too expensive, you'd better find some options to get addicted to it

10. Pishon platform is OK. It is the world's first superconcting mechanism. It's decentralized, smart contract, chain execution, full open data, fair, just, open and transparent. It's the world's first mechanism based on wave field development.
