blockchain finance is actually the application of blockchain technology in the financial field

blockchain is an underlying technology based on bitcoin, and its essence is actually a decentralized trust mechanism. Through sharing in distributed nodes to maintain a sustainable database, the security and accuracy of information can be achieved. The application of this technology can solve the trust and security problems in the transaction, and the blockchain technology has become an optional direction for the future upgrading of the financial instry. Through the blockchain, both parties of the transaction can carry out economic activities without the help of the third-party credit intermediary, so as to rece the cost of the global transfer of assets

extended data:

since 2016, the major financial giants have also heard the news and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency. Standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization. After careful digital algorithm, it is written into the blockchain to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the global asset circulation, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016, at which the discussion on the realization of digital circulation of assets, block chain financial transaction mode, and block chain financial transaction mode will be held It also discusses the application of blockchain service and social public instry

On August 16, 2018, Shen rujun, executive director and vice president of Bank of communications, gave a briefing at the regular press conference of the banking instry“ As of July 26 this year, BOCOM has opened 20 domestic certificates of blockchain, with a total amount of 156 million yuan. "

It is understood that for a long time, domestic L / C transactions have to go through a number of banks and express service providers, such as the issuing bank, the advising bank, the paying bank and the negotiating bank. Each institution completes the records in its own accounting system. The information between institutions is isolated and opaque. There are many problems in document processing, such as difficulty in authenticity verification, low efficiency, easy delay, easy loss and so on

in April 2018, BOCOM blockchain domestic L / C project was put into operation. As of July 26 this year, BOCOM has opened 20 domestic certificates of blockchain, with a total amount of 156 million yuan

SHEN rujun said that bocom continued to pay attention to blockchain technology, and analyzed and judged that the domestic L / C, bill and supply chain financial business will bear the brunt, becoming a breakthrough in the application of blockchain technology in the field of banking finance

in addition to L / C, the instry's first blockchain asset securitization platform "jucaichain" was officially launched in bocom on June 27. The basic asset information of the first housing mortgage loan securitization financing proct is linked by bocom, which realizes the credit penetration of the securitization financing business system

3. Now is the information age, no good technology is difficult to stand in the society,
now the rapid growth of computer technology, every company needs computer talents, you can go to learn computer professional,
there is still a lot of development space in this field, as long as you study hard, the future prospects are unlimited.

4. If you are a sophomore in high school, you can calculate the problem of analytic geometry
there's no saying that kind of trouble
if you can count all of them, you are definitely well trained in computing.

5. The combination of blockchain and bill can be developed into digital bill. The so-called digital bill is not a new physical bill, nor a pure virtual information flow. It is a brand-new bill presentation form developed by using blockchain technology, combining with the existing bill attributes, regulations and market. Compared with the existing electronic bill, it is completely different in technical architecture. For the specific content of the scheme, I think we can take a look at Yingtang Zhongchuang, which is good at blockchain application development.

6. This is part of the application of blockchain in the financial instry, and the feasibility of the integration of blockchain and bills is great
bill is a kind of valuable voucher, which needs a hidden "third party" role to ensure the safety and reliability of both parties in the transaction. However, with the help of blockchain, there is no need for a third party to supervise and verify the information transmitted by the two parties, nor for a specific physical object to be used as a proof to connect the two parties to obtain trust, thus realizing the "invisible" transmission of value between point-to-point
in the development of bill platform based on blockchain, Yingtang Zhongchuang said that the application of blockchain technology in the development of bill platform has the following functions: to realize the disintermediation of bill value transmission; Effectively prevent the risk of bill market; Change the existing system structure of electronic commercial draft; Improve operation efficiency; Standardize the market order and rece the cost of supervision
the advantages of the blockchain bill platform are as follows: the system construction and data storage do not need a central server, nor do they need a central level application; The integrity, transparency and verifiability of data can be traced and queried for any value exchange; The form of smart contract makes the bill programmable and controllable in the whole life cycle.

7. Ordinary electronic bills are stored in different platform media, which can not be well managed, and there is a problem of authenticity verification, so it is impossible to obtain the authenticity from the ticket. Ant chain electronic bills can be connected to a large number of billing units, including hospitals, schools, traffic police, etc., in one chain. They can be stamped in the whole process of generation, transmission, storage and use. The whole process can be traced and tampered with, and the authenticity and uniqueness are guaranteed. Thank you for accepting my answer

8. First, it can identify the authenticity of electronic documents without fear of malicious tampering or forgery
Second, the third-party trusteeship mode can effectively rece the cost of enterprise system construction and operation and maintenance, and the way to query and obtain electronic vouchers from a trusted third party provides a safe and reliable access channel for enterprise users
thirdly, solving the trust bottleneck faced by the data storage instry is concive to business development
fourthly, the e-Voucher can be traced by recording e-Voucher summary and flow record, which meets the needs of business supervision and review
in depth bill network, together with Societe Generale digital fund, has launched a bill money witness system, which provides solutions to the possible risks in e-bill trading scenarios. Note witness refers to the DVP of inter enterprise note transaction, which adopts the transaction mode of "print the money first and write back", that is, the buyer first print the money to the special fund escrow account of Instrial Bank, the seller confirms that the fund arrives before endorsing, and the instrial system verifies the successful receipt of the e-ticket before settling the fund. In the whole transaction process, the deep note network only provides safe, efficient and convenient services, and does not touch the fund and e-ticket, Ensure the safety of funds and e-tickets.
