Background
The blockchain is a novel decentralized information technology, can safely store digital transactions or other data, cannot be forged and falsified, and is a bottom layer technology of digital currencies such as bitcoin, Ethernet currency and the like. And the transaction confirmation on the blockchain is completed by the consensus of all the nodes on the blockchain, and the block is packed and written after the consensus is successful. The block chain maintains a public account book for storing all transactions on the block chain network, and any node of the public account book on the storage block is a complete copy, so that the common account book can not be forged and falsified, information sharing is realized, and the efficiency of transaction and information circulation can be improved.
The federation chain, an implementation form of the blockchain, is only directed to members of a certain group and limited third parties, and the generation of each block is jointly determined by all preselected nodes. Members of a federation chain refer to enterprises, financial institutions, and other institutions that join the federation through federation authentication.
Enterprises in the same industry have some valuable industry information, and in order to enable the enterprises to develop better, many enterprises want to exchange information with the same company, but how to exchange the information safely and reliably becomes a difficult problem for the enterprises. At present, information exchange among enterprises is realized through business communication, and information can be obtained only after evaluation, so that timeliness is poor. In addition, the system architecture varies between different enterprises, and there are many limitations on exchanging information via the internet. Even if data are exchanged successfully, because each family manages own data in a centralized manner, the evaluation of the information after the data are obtained cannot be effectively known by the whole network.
