What is blockchain finance

1.

blockchain technology has the advantages of being difficult to tamper with and easy to trace. It can play a role in identity information management, trust mechanism construction, and credit information chain of small and micro enterprises

here is an example of a bank in Nanping:

e to the outbreak of online business, the original offline signing method has been unable to meet the needs of the rapid change of the banking business, and the bank's digital construction is imminent, but the bank's risk control department has strict compliance requirements:

< UL >

online business data sensitive privacy, Is the transmission secure

does the electronic signature have legal effect

can electronic evidence be accepted by the court

< / UL >

these concerns have become obstacles for banks to introce e-contracts and carry out business digital transformation

after adopting the unique ENA initiative forensics patent technology of the "real hammer" trusted electronic evidence platform, a bank in Nanping, through the clean server of the notary office, online carries out real-time preservation, storage and certification of the electronic data of the target system, records the whole process of the electronic data from generation, transmission to storage, and finally the notary office issues the forensics preservation report with official seal, The effectiveness of the documents is notarial documents, which can be directly accepted by the court. Because the report is issued by the notary office, it has more credibility than the self certification of the third-party E-contract platform, which solves the concerns of the risk control department of the bank at one stroke. The whole process is online and automated, and the front-end customer operation has no perception

at the same time, combined with the back-end case system of "real hammer" and the outsourcing execution service, the bank realized the rapid dispute resolution of Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problem that the bank cases are scattered all over the country and the cost of legal business trip is high; The litigation cycle is long and there is no efficient disposal channel

2. In addition to issuing money, block chain + finance can also be applied to areas such as supply chain finance, small and micro loans, etc., and the essence of Internet plus finance is to rece costs and improve efficiency when exchanging value. Many audit information can be traced back, and the coordination and coordination efficiency of many organizations can be improved.
now there is a good application of blockchain + finance, which is the public service platform of SMIC blockchain. They have direct business cooperation with Bank of Changsha in small and medium-sized micro loans
I hope the answer will help you. If you don't understand, you can continue to ask.

Fried coins or something

at present, the application of blockchain technology is virtual currency. Therefore, virtual currency is also known as the first real birth proct of blockchain. The popularity of virtual currency is also obvious to all, which has set off a frenzy of investment in many countries. According to foreign media reports, the number of virtual currency transactions in the United States has reached 5 million; South Korea is estimated to be the craziest nation in the world, with one in every 50 people speculating, and 31% of the working class buying and selling virtual currency; Venezuela has also issued the world's first virtual currency with the nature of national sovereignty - oil currency

with the popularity of virtual currency, market investors are not only satisfied with the conventional trading mode of buying low and selling high, but also actively seek more simple and convenient trading ways to obtain more profits. The virtual currency trend trading method was born and successfully captured the hearts of investors in a short time, becoming a major mainstream trading mode

according to

{rrrrrrr}

, the trend trading method of virtual currency is exclusively launched by speedxo, an international financial service provider with deep experience. It mainly deals with the currency pair composed of virtual currency and real currency, and it can make profits as long as it is bullish or bearish. For example, if an investor trades in "bitcoin / US dollar", he or she only needs to judge whether the price will rise or fall after 30 seconds, and buy up or down according to the trend. If he or she buys in the right direction after 30 seconds, he or she can get 93% of the net income of the investment amount. It is this kind of rise and fall are profitable, time-consuming, no need to take advantage of the market, the trend trading method quickly swept the entire currency circle

4. EBay insurance (EHS) face insurance. Now the blockchain project is too complicated and messy. Finally, there is a project with guaranteed security issued by Qing blue ocean Silicon Valley blockchain Instrial Park.

5. Recently, the principle of blockchain has been talked about by many people. Obviously, blockchain has been deified by many people. It seems that all walks of life can use blockchain technology. However, to some extent, it is like a black box. We all know that blockchain has many features and benefits, but we don't know how to do it. In fact, as long as you understand the principle of blockchain, you don't have to hesitate

blockchain is not a single innovative technology. Instead, it brings together many cross domain technologies, including cryptography, mathematics, algorithms and economic models. Combined with the point-to-point network relationship, it can establish trust effect by using mathematical basis, and become a decentralized system that can operate without mutual trust or relying on a single centralized organization, Bitcoin is the first set of P2P e-cash system built by using blockchain technology, which is used to realize a decentralized digital currency system and ensure transaction security and traceability

however, how does the blockchain work and what key technologies it contains make it known as the trust machine? How can a transaction be verified in a P2P network that does not trust each other without the traditional trust institutions (such as banks, stock exchanges, third-party institutions and other centralized institutions)

to understand the operation principle of blockchain, we can first distinguish between transaction and block. Here, we understand the operation principle of blockchain from the generation of a transaction in the blockchain to the completion of the verification process and illustrate a block, and further disassemble the five key technologies of blockchain, See how it can be based on zero trust, decentralized, traceable and non tamperable

viewing the operation process of blockchain from a transaction

in bitcoin blockchain, when a transaction is generated through a node or wallet, the transaction needs to be transmitted to other nodes for verification. The method is to encrypt the transaction data by digital signature and get a string of unique hash values representing the transaction by hash function, and then broadcast the hash values to other participating nodes in bitcoin blockchain network for verification<

generate a new transaction

when a new transaction is generated, it will be broadcast to other participating nodes in the blockchain network first

each node will put several new transactions into the block

each node will collect several unverified transaction hash values into the block, Each block can contain hundreds or thousands of transactions

decide who will verify these transactions

each node will calculate the workload proof to decide who can verify the transactions, and the node with the fastest calculation result will verify the transactions, which is the consensus approach

the node that has obtained the verification right will broadcast the block to all nodes

the node that completes the pow as soon as possible will broadcast its block to other nodes

each node will verify and connect with a new block

other nodes will confirm whether the transaction contained in the block is valid, and accept the block after confirming that it has not been repeatedly spent and has a valid digital signature, At this time, the block is officially connected to the blockchain, and the data can no longer be tampered with

transaction verification is completed

once all nodes accept the block, the block that has not finished the pow calculation before will be invalid, and each node will re-establish a block to continue the next POW calculation

it can be seen that the principle of blockchain is not complicated, and its wide application is natural. Many companies have achieved fruitful results in the process of applying blockchain principles to reality. Bubi company is a leading blockchain service provider in China. It has made many breakthroughs in blockchain technology platform, which can meet the scenario of tens of millions of users, and has the ability to quickly build upper application business. Bubi blockchain platform is divided into bubichain and Bubi application adapters.

6. In addition to issuing currency, blockchain + finance can also be applied to fields such as supply chain finance, small and medium-sized micro loans, etc. just say it without practicing fake tricks. You can search the public service platform of SMIC blockchain. They do blockchain, and have a cooperation with Bank of Changsha in blockchain + finance. The project has also been implemented, so you can get familiar with it.

7. Blockchain finance is actually the application of blockchain technology in the financial field. Blockchain is a kind of 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
with a simple understanding, blockchain technology can be imagined as a fully centralized and super secure database. The reliability technical scheme of collective maintenance of a data book in a centralized way integrates distributed architecture, P2P network protocol, encryption algorithm, data verification, consensus algorithm, identity authentication, intelligent contract and other technologies, which can solve the problems of low security and poor reliability existing in the centralized mode. Although blockchain can not guarantee 100% security, compared with the current data security technology, blockchain is a huge leap. Unlike the centralized database, the blockchain will not have a single point of failure
the BSC project in Puhua business school takes advantage of the full centralization of blockchain to customize the underlying technology of blockchain and build a data sharing platform based on blockchain technology. Relying on the advanced network security system, it fully integrates the new technology, new thinking and new mode of the Internet revolution era, and forms a new business model with the core goal of win-win of BSC business alliance member enterprises and their associated customers.

8. First of all, EOS network has less traffic. Although the circulation volume of usdt of Ethereum network has just exceeded 20 billion, e to the congested network and high handling charges. The advantages of wavefield Tron are large flow, low cost, high penetration rate, rising flow and users! The large-scale release of wavefield versions of usdt, Eth and BTC on the wavefield Tron chain proves the high compatibility of wavefield ecology and the powerful throughput. Thank you for your question. I hope it will be helpful to you

9. There are many applications of blockchain technology in the financial field. To give a few simple examples:
the people's Bank of China launched the trade finance blockchain platform, which widely connects the information of tax, customs, foreign exchange and other departments, and effectively helps the financing and credit enhancement of small and medium-sized enterprises
Guangdong has released the first local financial off-site supervision blockchain system in China, which can effectively solve the problems of information asymmetry and unreliability between financial institutions and regulators in traditional supervision methods
State Grid supply chain financial data sharing platform based on data side chain: provide conditional and reliable sharing service of supply chain financial data under privacy protection, help small and medium-sized suppliers to revitalize accounts receivable, rece financing cost and increase financial income of financial institutions
in addition to these, there are other applications, such as cipher finance mimacaijing, which focuses on blockchain information.
