Financial technology blockchain of Xintong Institute

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).

2. Hello, the specialty of communication engineer is special, and the instry prospect is wide. Communication senior 20000 / year or so, communication intermediate 10000 / year or so, the working ability and working experience of engineers, determine their own market. Learn together.

3. Because the digital currency, which is the first generation of blockchain technology, has a huge impact on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology still belongs to a kind of technical means and tools. Its application in the financial field and the real economy is parallel. It has its own relative independence, but it also has a certain degree of intersection. That is to say, its role in promoting the real economy is indirect. 1. No matter in finance or entity, one of the bases of transaction between supply and demand is trust. The current bank to enterprise, enterprise to enterprise and enterprise to person are all linked by money. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or indivials can issue digital currency (Digital credit) by themselves in the future, and the status of banks will change from monopoly operation to equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has an indirect impact on the real economy. 2. Blockchain technology is the bridge between reality (entity) and virtual world. Through blockchain technology, the real world can be reconstructed, reconstructed and redefined in the virtual world. For example, the digital currency of real paper money in the virtual world, the digital stock transaction of real stock transaction in the virtual world, the digital settlement, digital customs clearance, digital documents and bills of real import and export trade in the virtual world can greatly improve the efficiency of business process and save the transaction cost. At present, all transactions are inseparable from the bank. The bank plays a central role in the transaction. The application of blockchain technology by the bank will certainly improve the efficiency of its settlement and indirectly promote the efficiency of the real economy, but this impact will graally weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a network system without center. 3. In fact, the application of blockchain technology is to value and credit the information flowing on the Internet. Through the blockchain, the information with (use value, exchange value, cultural value) in the Internet is reorganized and newly constructed to form a value Internet. It is of great significance. It will bring revolutionary promotion to both the financial instry and the real economy.

5. It has realized the application of blockchain in the six ecospheres of finance, medical treatment, real estate, automobile, infrastructure and environmental protection. Among them, only finance related scenarios include payment, clearing and settlement, insurance, asset transaction, loan, supply chain finance, etc.

6. Generally speaking, financial technology can be understood as the business application of scientific and technological innovation in the field of financial business
specifically, big data, cloud computing, blockchain, artificial intelligence and other technologies belong to financial technology, and these technologies have been applied in the business of financial field
for example, big data technology can be used to improve the ability of financial risk control. As we all know, risk control is very important for finance. Traditional banking instry focuses on risk control with existing credit reference data, while Internet technology companies with big data and deep mining ability can conct more comprehensive analysis and mining of data to improve risk control in financial business
for example, Internet giants such as the Internet use their own data advantages to develop and launch the "Prajna" big data risk control platform. Through the unique data features and algorithms of the network, and based on the data of hundreds of millions of users on the network, they enrich the credit information data and improve the risk control ability through graph calculation.

Blockchain is a kind of network with data; Hash Verification & quot; The purpose of the functional database is to verify the effectiveness of information, which is generally applicable to finance, insurance, public welfare, public services, mobile communications and other fields. Therefore, in recent years, many criminals have focused on the blockchain for online gambling to seek huge benefits. In January 15, 2021, the Jianhu police in Yancheng successfully cracked the first case of gambling in the country using block chain contract technology, and arrested 11 suspects, and the number of gamblers reached as high as 7.3 million. The funds involved were as high as 8 billion yuan , involving 17 countries and regions. p> In October 2020, Jianhu police received a clue that there was a new one on the public chain of grapefruit coin called & lt; Biggame” Grapefruit is a digital currency issued by foreign organizations, which is allowed to be used in public blockchain. There are more than 10000 people participating in this gambling app every day, and the daily bet amount is more than 10 million yuan. The way to participate in gambling is our common fruit machine, Red Black War and so on

have you ever been led to participate in virtual currency gambling
