Nearly 600 blockchains in the world

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

The ranking of exchanges on

non trumpets is shown in the figure, which changes every day

3. 1. Radiation engineers have strong lethality to infantry and non armored combat vehicles
2. Radiation engineers have less damage to armored combat vehicles
3. Radiation engineers have no damage to spiders and mining vehicles
4. Radiation engineers have no damage to buildings

these are the original data

4. Xu Mingxing, as a veteran of the blockchain instry, has a very forward-looking vision. He has experienced the whole development process of the blockchain instry. Xu Mingxing realizes that many procts of domestic cutting-edge instries still rely on the introction of foreign technology or direct import. As an emerging instry, if talents are equally important in the field of blockchain, but we do not pay attention to the cultivation of talents, the future of blockchain will be restricted by developed countries just like many traditional instries because of talents.

5. In addition to the postal service and Weizhong, the Bank of Changsha is now cooperating with a public platform called SMIC blockchain, which seems to be a blockchain loan business.

6. No problem. Leyte is the heavyweight currency in the okex trading area.

Since the birth of the blockchain, it has been in the vortex of controversy, but this does not hinder the popularity of the blockchain market. In the past three years, global blockchain talents have increased nearly 19 times. Although the increase is obvious, Lingying data shows that the total number of global blockchain talents is still relatively small, which is only about 2% of the global AI talents on Lingying platform, and the talents with "blockchain thinking" and "application development experience" are extremely scarce

Wang Di, vice president of LinkedIn China technology, said, "blockchain is an emerging technology model driven by technology community and still in the early stage of rapid development, which is not complete at present. Blockchain development needs decentralized thinking, practical application development experience and fast learning ability. In popular terms, blockchain development needs "soft skills" and AI needs "hard power."

"at present, talents with blockchain thinking and application development experience are very scarce." Wang Di believes that "enterprises intending to develop the concept of blockchain and explore business opportunities not only need such talents as project leaders, but also need to establish a longer-term strategic goal to cultivate and reserve more young technical talents, so as to seize the opportunity when the instry ushers in the real wind. In addition, we can also carry out talent and technical cooperation with the United States, the United Kingdom, India and other countries, and there are more talents with blockchain development experience in these countries than in China. "

at the end of 2017, Deloitte released an analysis based on the blockchain technology and projects on GitHub, a global software collaboration platform. At present, there are 86034 blockchain projects on GitHub, but only 8% of them are maintained, 5% of them survive, and the average life of the projects is only 1.22 years

if there is a fire, there will be a lack of everything

8. In fact, many countries around the world are vigorously supporting the development of blockchain technology, including China. Since last year's speech, the development of China, especially blockchain + government affairs, has been particularly rapid. I believe that through the development of blockchain + government affairs to promote the popularity of blockchain, all kinds of fields are linked with blockchain and have practical application landing. At the same time, when there are practical social benefits, it means that the world has entered the era of blockchain 3.0. Many blockchain + government applications in China, such as Changsha's SMIC blockchain public service platform, are actually the first blockchain 3.0 era to lead Changsha into. I believe there will be better and wider promotion in the future.
