1. blockchain is a public accounting mechanism
blockchain is decentralized, tamper resistant and anonymous
the blockchain system is actually a distributed system
bitcoin system is the earliest blockchain system and the simplest blockchain system
the whole bitcoin system is actually a distributed ledger. This ledger is backed up on each node. When a transaction occurs, it will be broadcast to the network. The miner node (the node solving the problem) in the network will mine (the node solving the problem) to record the transaction. The recorded block will be broadcast to the network, and other nodes will verify and synchronize to their own node's account book.

2. 1、 Blockchain will play the role of "recing costs for the real economy". At present, the high cost and low profit of the real economy lead to the lack of capital support for the real economy. In the operating cost, the proportion of management cost and financial cost is not low. Blockchain technology can effectively help enterprises rece the cost of these two parts
secondly, blockchain will play a role of "improving the efficiency of instrial chain collaboration". Enhancing instrial collaboration is an important way to promote manufacturing in China to move towards the middle and high end. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
thirdly, blockchain will play a role of "building an honest instrial environment". At present, the construction of China's social credit system is accelerating, but in some cases, the process of building trust among partners is still slow, it is difficult to obtain all kinds of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through the "transaction on the chain", all aspects can more easily find out the accurate historical credit situation of the counterparties, and establish the cooperation mechanism faster; Banks can also give credit to enterprises more safely based on transaction records, and promote the solution of the problems of "difficult, expensive and slow financing" of small, medium and micro enterprises operating in good faith
in addition, blockchain can make use of smart contracts to avoid default and fraud to a large extent, and can also make efficient and convenient payment scenario applications in combination with blockchain asset wallet. As early as in the blockchain circle, there have been many innovation forums and Instry Summit aiming at the direction of blockchain enabling the real economy, and combining with the local economic instry to carry out landing optimization. For example, the world blockchain conference Macao station intends to make a deep integration with the local economic instry, and use and popularize the blockchain assets with the payment means of magic chain wallet.

3. Principle of blockchain: decentralized distributed accounting system
the core of blockchain technology is that all participating nodes jointly maintain the transaction and database, which makes the transaction 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< br />?
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the blocks of the transactions that have been reached are connected together 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 miners 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
1.1 what is a blockchain
blockchain is a technical solution to collectively maintain a reliable database through centralization and de trust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block< br />?
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems, that is, a big ledger. So it's very important who keeps this account book. At present, whose system is responsible for bookkeeping, the account book of each bank is the account book of each bank, and the account book of each bank is the account book of Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. As a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system< br />?
1.2 why is there blockchain innovation
human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the information needs of market participants, so the intermediary and center were born. This centralized system has the problems of high cost, low efficiency, scattered value, "information island" and unsafe data storage. However, e to technical and environmental factors, this system still continues to operate for many years until the emergence of the Internet. The starting point of the first generation Internet is TCP / IP protocol, which is to implement the open code of peer-to-peer transmission of information in a unified format of all nodes on the network, and to program, protocol and execute the basic values of freedom and equality needed by the global unified market. Internet eliminates the middle chain of low value and high cost, and realizes the low cost and high efficiency of global information transmission by decentralization< br />?< However, the first generation Internet did not solve the credit problem of information. The activities that can be decentralized on the Internet must be those that do not need credit endorsement, and those that need credit guarantee must be those that are centralized and participated by third-party intermediaries. As a result, Internet technology, which is unable to establish global credit, has encountered great obstacles in its progress - people can not participate in any value exchange activities on the Internet in a decentralized way. In order to realize value exchange, people still need the third-party intermediary (such as bank, clearing, exchange) based on credit. There are still some problems in the global centralized credit system, such as high operating cost, low efficiency and vulnerability to attack. For example, the legal currencies of different countries have different credit values and different clearing systems, which increase the cost of Global trade< br />?
therefore, what the second generation Internet must break through is: how to decentralize the establishment of global credit? So that the value transfer is also low-cost and efficient. We need to create a kind of technology in the Internet, which can also engage in value exchange activities on the premise that people can't trust each other, so as to achieve real decentralization and go to the third-party intermediary, and realize the transformation from information internet to value Internet
1.3 application of blockchain
Bubi blockchain has been applied to equity, supply chain, points and other fields, and is carrying out experiments and application tests with exchanges and banks
as an integral application on Bubi blockchain, Shubei Hebao has been launched recently, which is a good demonstration for the landing application of blockchain technology in various instries
1.4 why the financial instry needs blockchain
trust is the foundation of the financial instry. In order to maintain trust, the development of the financial instry has spawned a large number of high-cost, low-efficiency, single point of failure intermediaries, including trusteeship, third-party payment, notaries, banks, exchanges and so on. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanism to maintain a complete, distributed and tamperable account book, so that participants can ensure the security of funds and information through a unified account book system without mutual recognition and trust. This is of great significance to finance. Therefore, global financial giants are exploring blockchain applications one after another. On the one hand, this is to prevent the risk of being subverted; on the other hand, it is also "for our own use" to improve efficiency and rece costs, so as to consolidate, optimize and expand the existing power< br />?
first, blockchain can rece trust risk. Blockchain technology has the characteristics of open source and transparency. The participants of the system can know the operation rules of the system, verify the authenticity and integrity of the account book content and account book construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system. For example, blockchain can avoid the current Internet Financial P2P running, fraud and other events< br />?
secondly, blockchain can improve the efficiency of payment, transaction and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, all transactions are displayed in real time on a spreadsheet similar to global sharing, real-time clearing, and efficiency is greatly improved. For example, the U.S. securities settlement system is t + 3, but the blockchain can improve the efficiency to the minute level, which can rece the settlement risk by 99%, thus effectively recing the cost of capital and systemic risk< br />?
thirdly, blockchain can rece operating costs. Financial business systems and back office work are often faced with long processes and multiple links. Nowadays, no matter visa, master or all of them operate in a centralized way, money transfer has to go through a third party, which makes the cost of cross-border transaction, currency exchange rate, internal accounting and time cost too high, and brings risks to capital. Blockchain can simplify and automate the lengthy financial service process, rece the interaction between foreground and background, and save a lot of human and material resources, which is of great significance to optimize the financial business process and improve the financial competitiveness. The Bank of Spain believes that by 2022, blockchain technology will help the financial instry rece its bookkeeping costs by $20 billion< br />?
fourthly, blockchain can effectively prevent failures and attacks. The traditional financial model takes the exchange or bank as the center. Once the center fails or is attacked, the whole network may be paralyzed and the transaction will be suspended. The blockchain is supported by many distributed nodes and computer servers on the point-to-point network. The problems of any part will not affect the overall operation, and each node keeps a of the blockchain data. Therefore, the built-in business continuity of blockchain has high reliability and fault tolerance< br />?
fifthly, blockchain can improve the level of automation. Since all files or assets can be represented in the form of codes or ledgers, smart contracts and automatic transactions can be realized on the blockchain by setting the data processing program on the blockchain. For example, a smart contract can write a set of financial terms into the agreement to ensure the automatic execution and default payment of the contract< br />?
sixth, blockchain can meet regulatory and audit requirements. The records stored on the blockchain are transparent, traceable and unchangeable. Any record, once written to the blockchain, is permanent and cannot be tampered with. Any transaction between two parties can be tracked and inquired< br />?
in addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. On the other hand, blockchain greatly encourages the innovation and cooperation of the whole society through the opening and cooperation of source code. Of course, there will be a lot of problems and challenges in the application of blockchain in finance. This paper also thinks about the specific application
the working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.

4.
the instries that benefit from blockchain creation include: e to the high degree of integration, blockchain technology can not only provide technical support or meet the needs of scenarios for enterprises in the financial field, but also proce catalytic effect on some manufacturing enterprises after integration through their own characteristics such as high-end equipment
with the graal maturity of blockchain technology, six fields supported by science and Technology Innovation Board will adopt more and more research reports released by lianxun securities show that with the help of policy dividend and instrial capital, the application of blockchain technology is expected to develop rapidly in the future, and graally radiate to other instries and scenarios starting from the financial instry
5. The blockchain proct of four technologies is a kind of virtual currency, which can be used as the material of currency. It mainly evolved from proct exchange to metal currency to paper currency, and then to today's digital currency.
6. In just a few years, blockchain has developed from 1.0 era to 3.0 era. The update of each "era" has brought changes to the world. The development of blockchain can be divided into three stages from 1.0 era to 3.0 era: point-to-point transaction, transaction and transaction Smart contract and blockchain application Ecology (token economy)
blockchain 1.0 era: digital currency rate of return is the king
blockchain 2.0 era: smart contract provides infrastructure support for upper application development
blockchain 3.0: the subversion of business lies in the transformation of proction relations
all obstacles to the development of human society, Fundamentally speaking, they are all caused by "mutual distrust", especially various economic and financial crises. If human beings can solve the problem of mutual trust, then human beings will complete a very big leap forward
the development of blockchain has graally laid the foundation for this direction. Human beings are entering the era of "smart contract", which is the process of upgrading human trust mechanism. Once the smart contract is reached, human society is facing a new big upgrade. As a value creator, the value created by each indivial can be accurately recorded and the corresponding return can be obtained, There will be less and less mutual interference, and people are really moving towards independence and equality. Human civilization has evolved from "identity society" to "contract society", and blockchain is expected to lead human beings to transition from "contract society" to "smart contract society"
although blockchain has gone out of the conceptual stage, the current situation of blockchain technology development is that the underlying technology is not mature enough and the application scenarios are relatively limited. On the one hand, consensus algorithm and other core technologies of blockchain still have room for optimization and improvement; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms are originated from foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the global blockchain technology development. It still needs a certain period of time. It can be said that the whole domestic trend is waiting for the emergence of a super level blockchain project
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
