Description
Technical Field
The present invention relates to the field of block chaining, and in particular, to a block chaining mapping relationship storage application system and method.
Background
The distributed account book means that transaction accounting is completed by a plurality of nodes distributed in different places together, and each node records a complete account, so that the nodes can participate in monitoring transaction validity and can also jointly make a proof for the transaction.
Unlike traditional distributed storage, the uniqueness of distributed storage of blockchains is mainly reflected in two aspects: firstly, each node of the block chain stores complete data according to a block chain structure, and the traditional distributed storage generally divides the data into a plurality of parts according to a certain rule for storage. Secondly, the storage of each node of the block chain is independent and equal in status, the consistency of the storage is ensured by means of a consensus mechanism, and the traditional distributed storage generally synchronizes data to other backup nodes through a central node. No one node can record ledger data alone, thereby avoiding the possibility of a single bookkeeper being controlled or being bribered to account falsely. The accounting nodes are enough, so that the account is not lost unless all the nodes are damaged theoretically, and the safety of the account data is ensured.
At present, in the harvest control of an automatic harvester for intelligent agriculture, an effective technical scheme for applying a block chain technology is lacked, so that the advantages of the block chain technology cannot be fully utilized.
