Block chain is responsible for storage in the clearing system of
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,
in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness
however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

using ordinary computer CPU does carry out bitcoin mining. Because bitcoin mining has formed a huge instry all over the world, ordinary computer is difficult to dig bitcoin. You need to buy expensive and professional bitcoin ASIC mining machine and join bitcoin miners' organization to dig bitcoin, that is, join the mine to dig Mining
bitcoin mining machine market has a high threshold. It is suggested that new players who want to dig for gold should be cautious.
at present, bitcoin mining needs professional ASIC mining machine. For example, Avalon mining machine, the mainstream of the market, is said that Avalon's fourth generation 28nm process chip, that is, chip flow, is expected to focus on the fifth generation 16nm process chip
in fact, only high-level security data can be used for blockchain development, and most companies do not have this requirement. It can be understood that there are so many companies in the world, only a small part needs to use big data technology, and a smaller part needs to use blockchain technology. These two parts can intersect but do not include
for companies that normally use big data, there are non relational databases like HBase, mongodb, hive, Mr, spark and so on in terms of storage and processing, which have nothing to do with blockchain.
The clearing center is the Department that handles the accounting and management of the fund transfer between the handling banks in the system, the fund clearing between the clearing banks, the fund loan and account reconciliation
internal organization: Office (Party committee office, discipline inspection office), human resources department (Party Committee Organization Department), career development department, financial management department (Procurement Office), business management department, technology management department, development department (Development Center), engineering department, operation Department, affairs management department, Wuxi main station, infrastructure office, Shanghai center preparatory group, The preparatory group of central bank accounting data centralized system (ACS)

extended data
the payment and clearing systems operated, maintained and managed by the general clearing center of the people's Bank of China include HVPS, BEPS, CIS, cdfcps, etc Electronic commercial draft system (ECDs) and online payment inter-bank clearing system (IBPs) are important financial infrastructure in China and the main artery of national and social capital flow
"establishing and improving a unified, efficient and safe payment and clearing system", creating a harmonious payment and building a harmonious financial service environment are the unswerving efforts of the clearing center. The general clearing center is earnestly implementing the deployment of the Party committee of the people's Bank of China, Solidly Promoting the construction of the payment and clearing system, fully ensuring the safe and stable operation of the payment and clearing system, vigorously expanding the field of clearing services, striving to improve the level of payment and clearing services, and achieving the goal of "the mainstay of central bank's payment"
