Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] A blockchain data storage extension method based on on-chain storage, the method comprising:

[0033] S1. Use the host or server as the blockchain node to build a Hyperledger Fabric blockchain network. Each node in the blockchain network optimizes the transaction data and packages the optimized transaction data;

[0034] S2. Send the packaged transaction data to the endorsement node for verification, and perform block sorting and compression after verif...

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...
