Will the two sessions raise the issue of blockchain
although the currency circle is in a bear market, blockchain is not useless without cryptocurrency
the blockchain instry has developed rapidly in recent years, and more and more blockchain technologies appear in front of people. More and more blockchain applications are landing, blockchain e-invoice, blockchain traceability, blockchain finance and so on. Talents in the blockchain instry are also very scarce. Many colleges and universities in China have set up blockchain courses to provide talents for the blockchain instry
the development of a new technology will inevitably encounter setbacks, and the blockchain instry will grow stronger in the future.
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of each node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system.
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

in fact, the sharp rise of dog money has a lot to do with Tesla's boss, musk. With his help, the dog money rose on a large scale
since its birth, digital currency has been loved by many investors because of its decentralization and concealment. With the soaring price of bitcoin, people seem to see the wealth code. Many people have issued their own currency on this basis, among which dogcoin was born
dogcoin is not conspicuous among many digital currencies, but with the help of musk, dogcoin has skyrocketed and its price has been guaranteed hundreds of times. Many investors are optimistic about dogcoin and buy dogcoin{ RRRRR}
3. The surge of dog currency has gathered risks, so people should be cautious in investment< p> The price of dog coin has skyrocketed a hundred times, but dog coin has little use value. In addition, dog coin can be issued unlimited, so the price of dog coin is too high. Buy dog coin, in fact, there is no value support, just for speculation, so people should be more cautious when investing in dog coin The popularity of dog money is the result of artificial hype. If you have any other opinions, please leave a message to discussgenerally, there are two situations of position locking: profit position locking and loss position locking
profit lock is that the procts that investors buy and sell have a certain range of floating profits. Investors feel that the original trend has not changed, but the market may have a short-term block or rebound, and investors do not want to easily close the position with the original low price or high price, so they continue to hold the original position and open a new position in the opposite direction
loss lock is that the procts bought and sold by investors have a certain degree of floating loss. Investors can't see the future market clearly, but they don't want to turn the floating loss into actual loss, so they continue to hold the original loss position and open a new position in the opposite direction in an attempt to lock in the risk. Whether it is profit lock or loss lock using the same method and principle, so there is not much difference in essence, both are wrong.
