Abstract

The invention provides a method and a device for executing a transaction in a block chain, which are applied to a block chain node. The method comprises: receiving a plurality of first transactions belonging to a first block, and pre-executing the plurality of first transactions to obtain a pre-execution read-write set of the plurality of first transactions, wherein the pre-execution read-write set is used for grouping the plurality of first transactions; carrying out consensus on second blocks in parallel in the pre-execution process of the multiple first transactions; the second block is a block before the first block.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of blockchain, and in particular to a method and device for executing transactions in blockchain. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In the blockchain system, the data blocks are combined into a chained data structure in a sequentially connected manner in chronological order, and the data blocks are cryptographically guaranteed to be tamper-proof and unforgeable. When a blockchain node executes multiple transactions in a block, it can speed up transaction execution by executing transactions in parallel. However, since the variables accessed cannot be predicted before the transactions calling smart contracts are executed, they usually cannot be executed in parallel. Contents of the invention [0003] One or mo...
