Block chain data storage expansion method based on chain storage

Abstract

The invention belongs to the technical field of block chains, and particularly relates to an on-chain storage-based block chain data storage expansion method, which comprises the following steps of: introducing half-node storage partial block detailed data and all block index values; introducing a secondary chain to store hash block group data; each node in the block chain network optimizes and packs the transaction data; sending the packaged transaction data to an endorsement node for verification, and performing block sorting compression after verification; the leader node accepts and verifies the sorted and compressed blocks, and the blocks are broadcasted to all nodes of the network after verification succeeds and are subjected to uplink storage; and when the height of the new hash blocks reaches a preset value, combining a plurality of continuous new blocks into one hash block group, and determining whether the new nodes store data according to the data storage quantity of each hash block group. The structure optimization and compression are performed on the data of the block chain, and meanwhile, the half nodes are introduced to reduce the bloating of the network data of the block chain, so that the data storage efficiency is improved. And the efficiency and authenticity of all the nodes during transaction data query can be ensured.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain data storage expansion method based on on-chain storage. Background technique [0002] Blockchain is a technology that combines distributed consensus, encryption, time stamping and other methods to realize peer-to-peer transactions, coordination and collaboration without relying on any third-party centralized organization; blockchain has the characteristics of decentralization, security Among them, blockchain scalability means that with the application of the blockchain system, minor changes such as parameter adjustments or hardware upgrades enable the system to support new requirements. Blockchain scalability can be divided into performance scalability and functional scalability, and performance scalability includes throughput expansion, storage expansion, and network expansion. Throughput expansion is related to the number of transactions in each...

Problems solved by technology

Off-chain storage is to transfer part of the data storage to another external data storage system to relieve the storage pressure of nodes in most blockchain networks but there are security issues; while on-chain storage does not require each node to store a complete block The blockchain ledger does not depend on additional off-chain storage systems, and only requires each node to store the corresponding part of the ledger according to pre-agreed rules
