With the development of computer and internet related technologies, mass data are widely applied in life, and more complete databases are often established in various fields of society, but different databases are often customized by each party according to the business requirements of each party, and different data platforms have great difference, so that the interaction of data among the parties has great obstacles and low convenience, and therefore, the problems of data exchange and sharing are increasingly concerned.
In order to solve the problems of data exchange and sharing, methods such as point-to-point data exchange, setting up a data center for exchange, and the like have appeared. The limitation of the point-to-point data exchange method is obvious, namely the efficiency is low, and the method can only be applied in a small range and cannot meet the requirement of mass data sharing in the current society. The method for setting the data center solves the problems of data exchange and sharing to a certain extent, but all data are exchanged through the data center, which brings the problems of high maintenance cost, additional cost increase, insufficient efficiency and the like, and simultaneously causes the problem of insufficient openness and transparency of the data. In recent years, the concept of "decentralization" has become more and more well known, which means that there are many highly autonomous nodes in a network, each of which can produce content or communicate with other nodes, and no permanent center is needed for content distribution, and any node can become a phased center. The decentralized mode can reduce the cost of data circulation, and is the direction of future internet technology development.

Therefore, the method brings the disadvantages of low efficiency, increased service cost, and unclear and transparent supervision.
In general, a company alliance method can be adopted to solve the problem of information sharing, a alliance is established by a plurality of companies, various information is shared and maintained in the alliance, a uniform interface is used for data exchange, data updating, data query and other operations, and a certain admission mechanism is matched, so that all parties in the alliance can conveniently use shared data. With the development of technology in recent years, block chain technology with decentralized feature has been used in many applications in the field of data exchange. The alliance chain is a block chain which only allows certain specific groups to join the network, has certain admission conditions, and carries out data sharing and exchange based on the alliance chain technology, so that the efficiency can be improved, and the safety and the privacy of the data are guaranteed.
