the main sponsors of the alliance include Shanghai Institute of development and reform, China financial information center, Wanxiang blockchain laboratory and blockchain pencil; The co sponsors include bumeng (Shanghai) Technology Co., Ltd., bitse, Shanghai Juzhen Financial Information Service Co., Ltd., Shanghai Institute of science, Jiading Instrial Zone Economic Development Co., Ltd. and Lujiazui Internet Finance Association
with the rapid development of the Internet, the proportion of digital assets and digital assets in people's real life is increasing. The characteristics of blockchain, which can not be tampered with and shared, can solve the problems of data authenticity and data ownership, so it is regarded as the best solution for all data related instries, including the financial instry
the alliance is committed to building a platform for cooperation, exchange and dialogue between government departments, relevant enterprises, scientific research institutes, financial institutions and instrial parks, organizing in-depth cooperation among government, instry, University, research and finance, and promoting blockchain instry research, instrial policy support, technology research and development, standard formulation, business incubation, talent cultivation, etc, Attract high-end resource elements of blockchain to gather, promote self-discipline of instry development, create a good environment for the development of blockchain instry, and promote the development of Shanghai into a highland of blockchain technology R & D Application and instrial development with strong domestic and foreign influence
as the world's first commercial blockchain digital asset platform, bumeng actively responded to the call of the government and the needs of the instry and joined the alliance“ The mode of blockchain is free and democratic, but freedom and democracy need to be supervised. " Yang Fan, general manager of bumeng, said, "the reason why bumeng joined the alliance is that he hopes to have a platform for communication with government agencies, and promote the healthy development of the blockchain instry and financial market through communication with relevant government agencies."
as a hot topic of financial technology, Yang Fan provides a scene for the application of blockchain in the financial field: "blockchain technology can provide real and reliable data for the financial field, and has great potential in risk control, credit reference and other big data. At the same time, regulators can also become one of the nodes to better and lower the cost to achieve regulatory purposes and improve efficiency. "
"in the future, bumeng will actively participate in the alliance activities, actively communicate with alliance members through business sharing and other ways, show the public the innovative achievements of blockchain technology and application, and make its own contribution to the development of the alliance." Yang Fan concluded

2018 has entered the countdown, and the first year of blockchain is coming to an end. In 2018, blockchain technology has received great attention all over the world, and the governments of various countries are actively making efforts in the field of blockchain in an attempt to seize the commanding height of the next instrial innovation. According to the blockchain instry yearbook, in terms of talent supply, there is a large shortage of blockchain talents, and there is a high demand for compound talents. In addition to social training and training, colleges and universities have started blockchain courses
for example, Stanford University, Massachusetts Institute of technology and University of California, Berkeley have begun to offer courses related to blockchain or digital currency. Moreover, many online courses and large-scale open online courses also began to provide relevant training services
it is true that as a "young" technology, the main force of future development of blockchain technology is bound to be young people. But at present, many practitioners in the blockchain instry are self-taught, without systematic professional knowledge training, or only one-sided talents in cryptography, programming, Internet technology, etc
and blockchain technology pays more attention to compound talents with multiple technologies, which may be the internal reason why blockchain talents are increasingly becoming just needed. In 2019, blockchain technical talents seem to have become new professionals, and will be highly competitive

(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
