SFIS blockchain risk
the centralized trading platform covers the whole trading process including account opening, recharge, automatic transfer and transaction withdrawal. That is to say, when we put our digital assets into the address of the trading platform, the trading platform becomes the trustee of our digital assets, and the control of the actual assets is in the hands of the trading platform
different from the centralized trading platform, the decentralized platform does not need to register an account. It only needs to undertake the responsibilities of asset custody, matching transaction and asset clearing, and does not need to provide non trading function, account system, kcy and legal currency exchange functions like the centralized exchange; On the other hand, in the decentralized trading platform, all operations are realized through smart contracts, and this transaction needs to wait for the confirmation of the blockchain before it is successfully completed
based on the above attributes, the decentralized platform avoids the moral hazard of the trading platform and the centralized attack of hackers to a certain extent. However, in this trading mode, the security of assets depends on the users themselves.
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

the block chain market is often compared with the early Internet age, especially in analogy with the 2000 Internet bubble. Simple analogy will convince you that we are in the Internet age similar to 1997-1998 years ago, and that once we enter 2000, we will have the same bubble burst.
people with this idea will let you leave the current blockchain, wait for the impending crash, and then pick up the pieces, similar to the end of the Internet bear market in 2002. But what we may also see is:
"instead of reconstructing the whole blockchain field through one big crash, there may be a series of small crashes, one after another. Every small crash will kill some tokens of poor projects, and bring new projects with higher and higher quality. "
so if you're waiting for a blockchain crash. It may never happen. Because it's happening all the time, though by a small margin. More importantly, if you are a venture investor, if you skip this period, you will miss the opportunity to learn and accumulate experience. In 2000, the collapse of the Internet reced the funding for new technology companies, but the fluctuation of the market value of blockchain hardly affected the pace of innovation of decentralized open source projects.
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.
