The blockchain technique is to verify and store data using an encrypted chained blockstructure, generate and update data using a distributed node consensus algorithm, program and manipulate data using automated script code; the data blocks are stored in the database and are arranged in time sequence, a plurality of transaction records are stored in each block, and the blocks are generated by applying a cryptology method to ensure that the data cannot be falsified, forged and verified; and using a consensus algorithm to enable all nodes in the whole network to complete the approval of the block.
The technical scheme is a government-level software system, needs fine management on users participating in the activities of the chain, such as identity authentication, license authorization, encrypted transmission and the like, and therefore adopts the alliance chain of admission license. The alliance chain is one of block chains, only aiming at members of a specific group and limited third parties, a plurality of preselected nodes are internally designated as bookkeepers, and the generation of each block is jointly determined by all the preselected nodes.
The directory chain is used for recording directory entities combed by each data resource owner, and generating blocks after countersigning and verification by related departments and then chaining, wherein the directory chain blocks contain contents including but not limited to department information, index descriptions, index fields, field descriptions, data updating periods and the like.
The data link is used for recording data content abstract, namely the data entity is not linked, the data entity is still stored in a local database of a data owner, and the data link block comprises content department information, data introduction, data updating time, resource path and the like; according to the convention of the alliance members, block generation time, the content of the block containing indexes and the like can be set, and the block is subjected to countersign verification by the authoritative node and then is uplink.
The application chain is used for recording transaction and sharing behaviors of data, all operations on the chain are notified to nodes through a message distribution mechanism, and a block record uplink is formed. The application chain includes, but is not limited to, transaction events, transaction times, information about both parties to the transaction, transaction times, etc.
As shown in fig. 1, in the uplink storage process, each data resource owner agrees to the uplink operation of the directory after signing, the related department organizes the data and generates a block, and generates a Hash value by asymmetric encryption, each authoritative node verifies that the chain can be linked after passing through, and broadcasts all nodes on the notification chain by a message distribution mechanism, and the synchronous billing is performed.
