Problems solved by technology

[0003] Although the new EOV framework effectively improves the concurrency of transactions, the MVCC (multi-version concurrency control) check mechanism that acts on the Validate (verification) stage may cause a series of conflicting transaction excessive abort
Since the blockchain itself requires expensive encryption and consensus in transaction processing, such suspension will reduce transaction throughput

Embodiment Construction

[0030] The specific implementation process of the snapshot-based Hyperledger Fabric transaction processing optimization method is given below:

[0031] 1. Assume that the current block number to be produced is N (N>3), and the existing waiting transaction queue has transaction T 1 , T 2 , where T 1 and T 2 In the execution phase, execute on block numbers N-2 and N-1 respectively, T 1 Read A, write B, T 2 Read B, write C, at this time there is a write set key-value pair for the committed transaction, Write-only transaction set is empty, T 1 , T 2 All have passed the dependency detection analysis and reordering feasibility analysis, and there are T 2 point to T 1 The edge of is labeled T 2 ->T 1 ;

[0032] 2. When there is T 3 Executed on N-2 and there is a read B and write C to reach the sorting node, first perform dependency detection and analysis on it, judge it as a read and write transaction, and then detect whether there is a cross-block concurrent anti-rw dep...

Abstract

The invention belongs to the technical field of blockchains, and particularly relates to a distributed account book platform transaction processing optimization method based on snapshots. The method comprises the following steps: subdividing transactions in an EOV framework used by a distributed account book platform, and defining a blockchain system concurrent transaction type suitable for the EOV framework; analyzing the dependency relationship between abnormal transactions in the distributed account book platform, providing a blockchain system transaction serialization scheduling strategy based on an EOV framework, and carrying out transaction reordering according to the scheduling strategy; and realizing the transaction processing optimization based on snapshots on the distributed account book platform, so the performance of the distributed account book platform under various load conditions is improved and analyzed. Experiments show that the optimized analysis distributed account book platform is superior to native Fabric versions and various existing optimized Fabric versions in the aspects of effective transaction throughput and average transaction delay.

Description

technical field [0001] The invention belongs to the technical field of block chains, and specifically relates to a snapshot-based distributed ledger platform (Hyperledger Fabric) transaction processing optimization method, that is, a method for optimizing Hyperledger Fabric to improve its performance under different conflicting loads. Background technique [0002] With the continuous development of the blockchain system, in order to meet various practical business needs, the blockchain system no longer develops into a general transaction system as a cryptocurrency circulation platform. Ethereum and other public blockchains that support smart contracts are representative of the blockchain 2.0 era. Smart contracts enable users to perform customized operations on the blockchain, and smart contracts run openly and transparently on the blockchain. At this stage, applications such as decentralized finance, cross-border payment and settlement clearing are developed on the blockchai...
