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. 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.
3. 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.
4. 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.
5. Yes, blockchain is a high-risk project.
6. 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.
7. First, the risk of absconding with funds, the lack of audit and custody of the assets raised. Now a standard ICO is like this: it will issue a white paper, let's have a look, and then it will be over as soon as it is implemented. There are still many potential rules. For example, in the past few years, there were many cases where an ICO project came out and everyone invested in it, and then it disappeared. So far, it is still in this state. So there is still the risk of project proposer absconding with money< Second, the risk of over commitment. The traditional IPO is that the company should do well, and I'll sell it again, and everyone can see clearly. And ICO is for me to write a few pages, say what I plan to do and what functions I want to achieve, and then everyone will give me the money. Whether it can be realized well or not is a question mark
thirdly, there is a risk of overvaluation. At present, there is no detailed or convincing pricing mechanism. It is more likely that the project initiator will proce a pricing based on the needs of the project development or his own understanding, which may lead to the so-called stage high investment< Fourthly, investors are too optimistic. Investors may see more space for future ICO projects, but in fact, from a slightly long-term point of view, there can be no sustained huge profits
fifthly, it is difficult for investors to control the stock risk of the project. After the completion of the project, there is often a certain development cycle in the follow-up. How to develop the project and how to promote it. Few ICO projects have clear plans for future development. This means that investors can't control what they can do after they invest their money.
8. 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.
