Parallel blockchain fragmentation method based on intelligent contract optimization model

Abstract

The invention discloses a parallel blockchain fragmentation method based on intelligent contract execution optimization. The method comprises the steps that each miner node obtains a combined appointment transaction from a peer-to-peer network and sends a combined appointment transaction to a preprocessing module; the preprocessing module compares the received contract transaction with a historical transaction and then performs grouping optimization; an intelligent contract scheduling module performs concurrent execution of the intelligent contract on the optimized transaction based on an SV-SCC algorithm, and calculates a final state; an executed miner node generates a new block; a new block generated by a miner node is sent to all network nodes for verification and is added to a block chain after the verification is valid, meanwhile, a new conflict record is synchronously sent to a preprocessing module, and the preprocessing module updates a feature information statistical table FIS.According to the invention, high concurrent execution of the intelligent contract is realized, higher transaction throughput is realized, the possibility of overheating of a single node is reduced, and a feasible scheme is provided for a large-scale transaction application scene.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a parallel block chain sharding method based on smart contract execution optimization. Background technique [0002] With the popularity of virtual currency and the continuous increase in the scale of transactions on the chain, the performance defects of the current blockchain platform are gradually exposed (such as low throughput, lack of concurrency, etc.). In order to meet the needs of large-scale applications, the academic community has introduced a sharding mechanism to improve the transaction throughput of the entire platform through parallel processing between shards without reducing the degree of decentralization of the system. [0003] Sharding is the division of all nodes in the network into several subgroups. Each subgroup processes different tasks in parallel to increase the processing capacity of the system. However, in the context of this technology,...

AI Technical Summary

Problems solved by technology

Some existing methods use new types of concurrent smart contracts, aiming to improve the performance of smart contract execution, but will cause a large number of transaction blocking and restarts when the transaction volume increases, and have not been optimized for high-concurrency services

In addition, the concurrency control algorithm has a direct impact on the execution efficiency of smart contracts, so the existing SCC algorithm is not suitable for the blockchain fragmentation environment
