Joint specialty of Finance and blockchain

1. What is the domain of blockchain? Blockchain applications? The reason why we all say that blockchain is a subversive technology is that it is indeed the first time in the whole process of computer development that decentralized trust can be established from the technical level. Features: consensus, security and openness. First of all, blockchain is a multi-party consensus mechanism, and the consensus algorithm is the basis of building the whole technology trust. It does not rely on the trust of people and institutions, but a relatively democratic mechanism. Under the constraint of this mechanism, the authenticity, validity and persistence of data are guaranteed, so as to establish the trust foundation of this alliance business of multi-party Union and multi-party mutual supervision

secondly, blockchain is a relatively safe system. bitcoin is such a familiar blockchain application, and it is also the most successful blockchain application so far. So far, bitcoin has been running stably for 6-7 years. This system almost breaks everyone's idea of building a traditional financial system. First of all, it has no security facilities. Anyone who takes a machine into the network can join the network and work. In the whole bitcoin network, more than 80% of the machines are bare metal, They have neither good security protection nor any firewall measures; Secondly, because of the design of bitcoin, some of its data can track the history, prevent tampering and be irreversible

finally, it is an obvious feature of blockchain. It is a very open system. At present, there are many open source underlying implementations for your reference or use, and it is very scalable. It has been committed to establishing a multi center instry alliance or business alliance

Introction to Bubi blockchain

since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

there are two extremes in the development trend of blockchain. Some people advocate private chain, while others advocate public chain. In fact, more than 90% of the mainstream applications in Europe and the United States are instry chain or alliance chain, that is, the upstream and downstream of an instry, or the semi open blockchain built by core enterprises, such as R3, LINQ of NASDAQ supported by chain, and some instry applications made by Dah to Australian stock exchange or Morgan

in fact, in the process of development and use of blockchain, it is around the following three important links: consensus, balance of book efficiency and scalability. Some geeks, such as bitcoin or Ethereum, are completely public. There are also some private chains used for efficiency transformation or connection between subsidiaries within enterprises. Most of them are upstream and downstream of instry alliances. They gather together for heating or jointly expand the business scale, which is the mainstream instry chain at present

blockchain naturally has two kinds of attributes: voucher and transaction. The attribute of voucher makes it the entrance of asset securitization and asset number, and the attribute of transaction enhances the free circulation of assets. Therefore, blockchain may become the infrastructure to build a free circulation network of value in the future

the field of blockchain? Blockchain applications? Referring to the development history of the Internet, the value free circulation network constructed by the blockchain is also an independent partial value circulation network (instry chain, alliance chain) formed by various instries according to their own needs in the early stage. In the later stage, driven by the demand for cross instry asset exchange, the instry chain is connected in series by some ways of interconnection, The formation of a de facto free circulation network of common value (public chain).

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

3. No,

4. 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.

5. Blockchain is a revolutionary underlying technology. Its original function is bookkeeping. As a distributed general ledger, it can solve the credit problem, notarization problem, audit problem, right confirmation problem, etc. of the ledger, as well as the digital demand of physical assets. Blockchain application scenarios are characterized by "new database, multi business entities and mutual distrust". The financial instry has the characteristics of low trust among participants and high requirements for transaction record security and completeness, which is very consistent with the application characteristics of blockchain technology. Therefore, the financial services instry is one of the instries with the most blockchain technology landing projects and the most abundant scenarios, such as supply chain finance, asset securitization, credit reference and risk control. In the financial field, blockchain technology can not only reform the financial infrastructure, but also play a synergistic role in the scenes of supervision, transaction, credit reference, virtual currency and so on. For example, in the traditional financial environment, supervision is managed by reporting data from various business organizations, which will cause many disadvantages, such as "black box" operation, decision-making delay and so on. However, under blockchain finance, with the advantages of information transparency and penetration and regional centralization, the regulatory authorities can grasp all business information at the first time. At present, Internet financial companies such as fox financial services are vigorously developing blockchain technology. Through the characteristics of decentralized blockchain technology and distributed storage, they can enhance user information management and enhance regulatory efficiency.

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. 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.

8. Yingchi Hall of fame is the top non-public graphics card. Although the time of silent frequency is similar to 1060, the ability of overclocking is much stronger than 1060. The official power consumption is 165W, while 1060 is 120W. After overclocking, the power consumption will be higher. Pay attention to whether the power supply is enough. The price of 900 yuan can be bought, but please note that if you play a stand-alone game, it may explode in some games. As for mining, so to speak, there is no ore card in the 9 series, and the N card mining was started on a large scale in the 10 series. It may have been before, but it's too few. Before the 10 series, they used to dig with a-card.

9. The first is definitely because of policy support. Most of the blockchain instrial parks are dominated by the government. The second is the participation of local enterprises, including capital and technology. The third is to have blockchain application projects that can be supported. Changsha high tech Zone also has a blockchain Instrial Park. Now it has launched a SMIC blockchain service platform project, It is also a blockchain application landing project.
