Global blockchain network
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
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 bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. 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
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. 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
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated 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 the information can be transferred anonymously

China blockchain network: the leader of global blockchain
China blockchain network: the largest information exchange platform of global blockchain
as a blockchain with decentralized concept and distributed shared accounting technology as the core, it will be embedded in many links in the financial field in the future, such as credit enhancement, right confirmation, equity registration, financial trade, digital assets, etc. Blockchain is still in the primary stage of development, whether it is a large institution or a small company, blockchain is still on the road of exploration. As a distributed shared accounting technology, the latest and most cutting-edge technology in the field of financial technology, blockchain, in a greater sense, enables the parties involved to establish a trust relationship at the technical level. At present, this technology has a lot of imagination in the field of equity registration, right confirmation, clearing and settlement in the financial field, as well as in the field of logistics and proct authenticity traceability. Bubi's blockchain points out that at present, more Bubi's technologies are focused on commercial level blockchain technical support services, which specifically includes three areas. First, the field of digital assets includes other digital assets in addition to common points and check-in cards; The second is trade finance; The third is the field of equity, to improve the convenience of equity trading
the development history of blockchain? Blockchain will bring a new revolution in asset ownership in the future“ The first generation of Internet information solved the free transmission of information, but did not solve the problems of decentralization and asset ownership. " This problem can not be underestimated. At the level of capital market, if any technology can clarify the property rights of things that are uncertain, it will be a huge change for the whole market. In addition, blockchain will also lead the great changes in the field of credit enhancement. It is reported that China has about 700 million Internet users“ If every netizen adds tens of thousands of credit lines through blockchain technology, the amount of credit increase will be trillions nationwide, and it can be proved that all your credit is universal in the world at the level of blockchain. " In the future, three things will happen in Internet finance. First, there will be a good matching mode between asset side and liability side; Second, intelligent investment with two main modes of follow-up investment, suggestion and notification; Third, blockchain
"the blockchain model, as a foundation, rather than a business model, will solve a lot of credit problems. The largest blockchain market in the next three to five years should be in China."
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
has blockchain solved any problems
the most important thing of blockchain is to solve the problem of intermediary credit. In the past, it was difficult for two people who didn't know and trust each other to reach cooperation, and they had to rely on a third party. For example, in the past, there must be a bank or an institution such as Alipay. However, through the blockchain technology, bitcoin is the first time for human beings to complete the transfer behavior that can be trusted by both parties without the participation of any intermediary. This is a major breakthrough in blockchain
the development of blockchain? The history of blockchain development
blockchain technology is the underlying technology of bitcoin. In the early days, not many people paid attention to the underlying technology of bitcoin. However, bitcoin has been running stably for many years without any centralized organization operation and management, and there have been no problems. So many people have noticed that the underlying technology may have a great mechanism, and it can be used not only in bitcoin, but also in many fields. Therefore, bitcoin technology is abstracted, which is called blockchain technology or distributed ledger technology. So from a certain point of view, bitcoin can be regarded as the first application of blockchain, and blockchain is more similar to the underlying technology such as TCP / IP, which will be extended to more and more instries in the future.
at present, the overall planning and top-level design of the blockchain service network have been completed, and the construction of more than 40 public city nodes in 31 provinces and autonomous regions has been completed. The blockchain service network will be tested internally for half a year. In the future, China UnionPay, together with the state information center, China Mobile and other partners, will actively promote security and function testing, technical architecture optimization, business operation scheme formulation, basic service capacity building, innovative application promotion and other work, and finally realize the commercial operation of the whole system

Since the birth of the blockchain, it has been in the vortex of controversy, but this does not hinder the popularity of the blockchain market. In the past three years, global blockchain talents have increased nearly 19 times. Although the increase is obvious, Lingying data shows that the total number of global blockchain talents is still relatively small, which is only about 2% of the global AI talents on Lingying platform, and the talents with "blockchain thinking" and "application development experience" are extremely scarce
Wang Di, vice president of LinkedIn China technology, said, "blockchain is an emerging technology model driven by technology community and still in the early stage of rapid development, which is not complete at present. Blockchain development needs decentralized thinking, practical application development experience and fast learning ability. In popular terms, blockchain development needs "soft skills" and AI needs "hard power."
"at present, talents with blockchain thinking and application development experience are very scarce." Wang Di believes that "enterprises intending to develop the concept of blockchain and explore business opportunities not only need such talents as project leaders, but also need to establish a longer-term strategic goal to cultivate and reserve more young technical talents, so as to seize the opportunity when the instry ushers in the real wind. In addition, we can also carry out talent and technical cooperation with the United States, the United Kingdom, India and other countries, and there are more talents with blockchain development experience in these countries than in China. "
at the end of 2017, Deloitte released an analysis based on the blockchain technology and projects on GitHub, a global software collaboration platform. At present, there are 86034 blockchain projects on GitHub, but only 8% of them are maintained, 5% of them survive, and the average life of the projects is only 1.22 years
