Abstract

The invention discloses a low-redundancy block chain data storage and retrieval method and system. The method comprises the steps: reconstructing a traditional distributed account book, removing an account book data part, adding a query index part, and constructing a low-redundancy block data structure; realizing an uplink consensus mechanism between block chain nodes based on a Raft protocol; and after the leader node links the account book block, storing the data to the local, selecting an account book data backup node from the block chain network based on the Hash function, sending the backup data to the backup node for backup storage, and sending query index data to all other nodes for updating the query index. By reconstructing a block data structure, eliminating redundant account book data and newly adding a query index structure, a Raft protocol and Hash-based low-redundancy account book data storage and retrieval method is provided, and finally block chain low-redundancy data storage and traceability are realized.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a low-redundancy block chain data storage and retrieval method, system, equipment, and storage medium. Background technique [0002] Blockchain is essentially a distributed shared database, based on P2P network, cryptography, database and other technologies, without the need for a trusted certification center, to achieve data non-tamperable, non-repudiation and other properties. At present, blockchain technology has been successfully applied in e-government management, Internet currency trading platform, data exchange and sharing and other fields, and it has become a hot technology that has attracted much attention from the government, industry and academia. [0003] The blockchain uses a P2P network to connect peer nodes in a fully connected manner. The nodes transmit data in a broadcast manner, and each node synchronizes distributed ledgers in a chain structure...
