blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

different from the traditional distributed storage, the uniqueness of the distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to the block chain structure, and the traditional distributed storage generally stores the data into 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

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

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

blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security

based on the above characteristics, this kind of data storage technology can perfectly prevent the possibility of data being tampered, and can also be applied to many fields in reality, which provides a more secure and reliable guarantee for electronic contract signing than our electronic storage technology
