Bank blockchain big data

1. blockchain: it is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

blockchain is an important concept of bitcoin. According to the 2014-2016 global bitcoin Development Research Report issued by the Internet Finance Laboratory of Wukou School of finance, Tsinghua University and Sina Technology, blockchain is the underlying technology and infrastructure of bitcoin [2]. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

2. Big data: refers to the data set that cannot be captured, managed and processed by conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that needs new processing mode to have stronger decision-making power, insight and discovery power and process optimization ability

2. Blockchain and big data are hot topics. The development of big data is earlier than that of blockchain. At present, it has become a huge instry. The combination of developing blockchain technology and big data will bring about different effects. From a technical point of view, big data technology exchanges computing resources with trust, while blockchain technology exchanges computing resources with trust, so the combination of the two sets off a new wave of information security. Based on the characteristics of blockchain distributed data storage, decentralization, non tampering, traceability and trustworthiness, Chongqing jinwowo network technology group has established a strong blockchain research team to provide big data services with blockchain as the underlying technology.

As a traditional financial institution, banks are the most active Pathfinder in the field of blockchain. In recent years, many banks at home and abroad have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough in innovating risk management and simplifying transaction process. However, as an emerging technology, blockchain ecology is still in the process of establishment, and its application is very limited. Many problems still need to be solved graally in the development

"at present, blockchain can't run high-frequency and concurrent transactions, and network speed and computing power can't support it. For example, in the field of payment, if it is online shopping, it can be realized; If it's high-frequency futures trading, it can't be done. " Huang Zhen said

JIANG Peng said that at the beginning of designing the blockchain system, China CITIC Bank carefully demonstrated the business links suitable for the use of blockchain

"from the global experience, it is not suitable to use blockchain to build a large and complex system. Instead of trying to solve all problems with blockchain, we should focus on solving the core problems. It's time-consuming to build a too complex system. The technology is developing so fast that before the old system is finished, it will face the iteration of new technology. " Jiang Peng said

the idea of "only solving core problems" ensures that after the blockchain goes online, the relevant business operations of branches of China CITIC Bank can be upgraded without process transformation

Fan Bin said frankly that it will take time for banks to fully apply the blockchain, and IBM's investment in the blockchain open source community will continue, on the one hand to cultivate the market, on the other hand to compete for the commanding height of the blockchain platform. With the rapid iteration of blockchain technology itself, there is still a lot of imagination for financial institutions to use this new technology

4. "Big data" has been applied in almost all instries, and the era of big data has also brought a variety of data with rising value
because of its immeasurable value, it has become an important research topic

big data is so valuable, but it can only be concentrated in the hands of a small number of owners. And people's life will proce a lot of data. The problem is that indivials have no way to obtain and store their own data e to external restrictions

the blockchain enables each indivial to have all the data generated by himself, and has a way to trade, analyze... And ensure the security of personal data.

5. The five elements are about Yin and Yang, eight trigrams, Qimen, tunjia, heaven, earth, people, gods and ghosts. In general, it refers to gold, wood, water, fire and earth.

6. It may be running away or being sealed up. Anyway, illegal trading platforms have such risks.

7. Blockchain and big data are current cutting-edge technologies, and they can be combined with each other. Many big data platforms are based on blockchain. There are more than 30000 enterprises on the public service platform of SMIC's blockchain, which will connect all the enterprises together. In the future, it may radiate to the whole country.

8. 1. SEC social e-commerce chain uses blockchain technology to greatly rece the credit cost of big data
2. Sec social e-commerce chain uses blockchain technology to build the cornerstone of trust in the era of big data
sec social e-commerce chain can greatly rece the credit cost and realize the safe storage of big data based on the characteristics of "de trust and non tampering" of blockchain technology. Putting the data on the blockchain can liberate more data and make the data truly "circulate". The database application platform based on blockchain technology can not only guarantee the authenticity, security and credibility of data.
