Abstract

Embodiments of the invention disclose a block chain data processing method, apparatus and device, and a storage medium. The method comprises the steps of generating nodes through at least one micro-block, generating a gap between two adjacent key blocks, generating the micro-blocks according to transaction processing information received within first historical time, and sending the micro-blocks to a block chain network; and generating the nodes through the key blocks, taking generation time of the last key block in a current block chain as a time starting point, generating new key blocks according to abstract information of the micro-blocks received after the time starting point, and sending the new key blocks to the block chain network. According to the technical scheme, the block capacity can be effectively expanded, so that the throughput of the blocks can be increased; the verifiability of the transaction processing information is improved, so that the non-tampering characteristicof the block chain is enhanced; meanwhile, the overall difficulty and the attack difficulty of the block chain are improved, and the probability of system bifurcation is reduced, so that the securityand effectiveness of data in the block chain are ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blockchain, and in particular, to a blockchain data processing method, device, equipment, and storage medium. Background technique [0002] As an emerging distributed storage technology, blockchain combines point-to-point transmission, distributed consensus protocol, cryptography and other aspects of computer knowledge, and then becomes a new application mode. However, restricted by many factors such as the consensus mechanism and system architecture design, the current writing performance of the blockchain is not ideal, that is, the throughput TPS (Transaction Per Second) is low, which in turn causes blockchain network congestion. Among them, the factors that cause network congestion in the blockchain network specifically include block capacity, consensus mechanism, transaction fees, and multicast propagation. Blockchain network congestion may lead to slow transaction writing speed...
