Does blockchain need a master

1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

2. There are no specific requirements. It is recommended to experience the blockchain in bitmax. This platform has strong financial strength, security and technology, so it is very good to choose other countries for blockchain transactions.

3. Changsha high tech Zone initiated the construction of SMIC blockchain platform, which is for the majority of enterprise users

4. Jinwowo network analysis: more vividly, the blockchain is like an electronic linked list, which is composed of blocks one by one, and contains all the valid data in these blocks. Whenever new data appears, it will be packaged and summarized into a new block according to the consensus rules on the chain, and connected to the back of the original chain. Finally, in the whole blockchain system, each participant downloads and saves the complete linked list and updates it all the time.

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
