How should blockchain be listed

2. Very bad. The instry is in a mess
blockchain is not easy to do since 18 years ago. The instry is deceptive, professional cut leek. I remember that the blockchain network reported that Li Xiaolai was cutting leeks. Li Xiaolai was going to build a blockchain network, so that their second round of financing had stopped. It was said that they had sold it to a technology company in Guangzhou

Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange

according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang

Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology

Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc

Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting

4. 1) When your computer restarts, blue screen or crashes, what are you doing on the computer? Can you tell me? I will give you a more accurate answer as you said. Please tell me more about the performance of your computer before restart and your operation. It may be the restart caused by these operations. If you have any questions, please ask me (I will answer you again according to the information you provided). General restart is caused by their own incorrect operation, remember easy to cause restart operation do not do. The computer should not operate at full load, that is, when playing games, watching videos, downloading and watching web pages, other operations are most likely to restart, crash and blue screen. Therefore, when playing games, watching videos, downloading and watching web pages, do not operate other things. Hardware, CPU and other hardware temperature is too high, less memory card caused, hard disk bad, voltage instability, in the presence of inappropriate hardware is caused. 90% of the reboots are caused by improper operation of the computer. The card is the root cause of the reboots. If the operation of the card is not done, the reboots will be avoided or less. 2) If it is a power-on crash and you shut down before the improper operation has something to do with it? For example: playing games, watching videos, operating big things, using the computer for a long time caused by the card, right? Or download the inappropriate things, the failure will not happen for no reason, right? If you can't do it yourself, go to the maintenance office and find someone to help you. You should spend some time. If you can't start the machine by any means, it's caused by the sudden shutdown of the machine, resulting in the damage of the disk. One is to pull out the main board battery and put it on. The other is to put it on for a period of time and try it on. You can't just repair it. One is to put it for half a day or one day, and sometimes it will recover itself. The other is to reload the system. As long as you pay attention to your computer is not stuck, blue screen, suddenly shut down, boot will not be like this.

5. In fact, blockchain is a database for large-scale cooperative operations. It allows many different subjects to work together to complete a task without mutual trust, which is the essence of blockchain. Blockchain may be the earliest in agriculture, which is widely used in agricultural quality and safety traceability.

6. The blockchain project you mentioned, if it's a fun step project, it won't. Jianan Yun, a miner, has been listed.

In 2020, blockchain will be included in the scope of "new infrastructure" by the state, and at least seven provinces will issue blockchain support policies. In the same year, blockchain technology is graally moving from concept to implementation, and the application scenarios are blooming“ Blockchain + "has become a symbol of the continuous maturity of blockchain< Novel coronavirus pneumonia epidemic swept the world in BR />

2020,

2020. The uncertainty of world economic development has increased significantly. Governments and enterprises around the world explore the use of emerging technologies to rece the cost of economic and social operation, improve the efficiency of the real economy, and further seek new growth points for economic development

at present, with the cross innovation of blockchain, cloud computing, artificial intelligence and other new technology infrastructure, more and more vertical fields of real economy present the development pattern of "blockchain +" and the good momentum of "from virtual to real"

in order to avoid the transition from real to virtual, in addition to continuing to crack down on speculation, we must also guide the deep integration of blockchain technology and practical application scenarios. Therefore, various instrial application scenarios of "blockchain +" have become one of the inevitable trends of blockchain development

according to the white paper on blockchain (2020) recently released by China Academy of information and communication, as of October 2020, more than 262 listed companies have set foot in the field of blockchain, including 39 fields such as insurance, real estate, commercial department stores, security equipment, packaging materials and telecom operation. In the blockchain information service record list published by the state Internet Information Office, the number of blockchain projects of listed companies has reached 45

among them, finance is the most explored scenario in the application scenarios of blockchain technology, and there are specific projects in supply chain finance, trade financing, payment and clearing, fund management and other sub fields. According to the white paper, as of November 2020, among the registered blockchain information services in China, the number of projects in the field of Finance (including supply chain finance) ranked first, accounting for 36%

with the acceleration of the implementation of blockchain applications, "blockchain +" business has become the development focus for Internet backbone enterprises to enter the blockchain instry. Besides financial business, actively deploy Internet, traceability and supply chain & amp; Logistics, digital assets, government and public services, intellectual property, law, medical and other fields

at the same time, it is graally understood in the instry that blockchain is the basic component of trusted transactions, but this does not mean that blockchain can take over the world. It is necessary to combine blockchain with other technologies such as artificial intelligence, Internet of things, big data, 5g, etc., and form an integrated solution by using synergy effect to jointly help digital transformation

according to the relevant data, at present, the application of blockchain is mainly in the field of certificate keeping, and blockchain has entered the stage of how to make it better, more reliable, more stable, better expansibility, and able to accommodate more nodes from the perspective of engineering. He Baohong, director of the Institute of cloud computing and big data, China Academy of information technology, believes that this process will continue for a period of time or more, and the next step is to shift the technical competition of blockchain from engineering optimization to technology ecology and business ecology

in addition, it is understood that the blockchain instry has been improving for a long time, and the instry cognition has returned to rationality. With the central government's planning guidance for the development of blockchain technology, China's blockchain has made it clear that it is based on the alliance chain, focusing on the development idea of serving the real economy and optimizing public services, and the direction of instrial development is further clear. At this stage, the majority of practitioners' confidence in the blockchain continues to improve, and generally recognize the long-term strategic value of the blockchain

what is the prospect of "blockchain +" in 2021

with the graal improvement of China's blockchain instry chain, most blockchain enterprises not only focus on one aspect, but also present the trend of multi field collaborative development. According to statistics, Beijing, Guangzhou, Shanghai, Zhejiang, Jiangsu and Shandong are the provinces and cities with the largest number of registered enterprises among the 801 blockchain information service filing lists published by the state Internet information office

the core role of blockchain corresponding to the technical characteristics is mainly reflected in the three aspects of certificate deposit, automatic cooperation and value transfer. With its value potential being continuously exploited, the application landing scenario has graally expanded from the financial breakthrough to the real economy, government affairs and people's livelihood and other fields

and the core value of blockchain for the real economy is to promote the efficient cooperation between the upstream and downstream instries and enhance the efficiency of the combination of instry and finance. In the early stage of development, the application mode of blockchain mainly focuses on the deposit of documents and contracts. At the present stage, the application of blockchain instry is graally moving towards automatic collaboration and value interconnection such as government data sharing, supply chain collaboration and cross-border trade

2020 is the warm-up of 2021. In 2021, the use of blockchain, distributed ledger and smart contract tools will continue to grow as in 2020. With the deepening of blockchain technology, the instrial foundation of blockchain will be better and better, the instrial ecology will also develop rapidly, and the instrial chain will be widely distributed

from the perspective of instrial structure, blockchain instry is mainly divided into four parts: underlying technology, platform services, instrial applications and peripheral services

the first three parts show a relatively obvious upstream and downstream relationship. The underlying technology part provides the necessary technical procts and components of the blockchain, the platform service part builds a blockchain platform based on the underlying technology to run the corresponding instry applications, and the instrial application part mainly uses the blockchain technology to develop instry applications according to the actual scenarios of various instries, Realize the innovation of business collaboration mode in the instry

peripheral services provide support services for the instry, including instry organization, market research, standard formulation, system evaluation and certification, instry media, etc., which provide power for the development of instrial ecology

among them, as far as the instrial application of blockchain is concerned, blockchain is not only the result of innovation and development of information technology, but also the main booster of business process reconstruction and instrial interaction mode innovation of various instries

blockchain has graally expanded from the initial digital finance to supply chain finance, proct traceability and other fields, and now it has been applied in government affairs, people's livelihood, instrial management and other instries, with increasingly rich application scenarios, showing a trend of deep integration with other instries

at present, domestic enterprises focus on serving the real economy and improving the application development related to government affairs and people's livelihood, among which supply chain finance and proct traceability have accounted for half of all applications, and other areas such as government affairs and people's livelihood have become the key layout areas of manufacturers in the future, which is about to see explosive growth

after the cooling of blockchain investment in 2020, the blockchain instry may graally become rational in 2021. However, a relatively complete instrial chain and active market players provide a good foundation for the development of blockchain instry. The blockchain instry will also show a positive development trend in policy support, ecological construction, platform service, application landing and integration innovation
