Abstract

This specification provides a method and device for executing transactions in the blockchain, which are applied to blockchain nodes. According to the method, multiple first transactions belonging to the first block are received, and the multiple first transactions are pre-determined. Execute to obtain the pre-execution read-write set of the plurality of first transactions; the pre-execution read-write set is used to group the plurality of first transactions; when performing pre-execution on the plurality of first transactions During the process, consensus is performed on the second block in parallel; 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...
