Block chain transaction execution method and device

Abstract

The invention discloses a block chain transaction execution method and device. The method comprises the steps that a scheduler in a block chain system obtains each first transaction in a to-be-chained block, and each first transaction is a transaction which needs to call an intelligent contract for execution; the scheduler determines each execution stage of each first transaction, performs parallel execution on each first transaction in the same execution stage through each transaction executor in the block chain system, and performs serial execution on different execution stages in sequence. The intelligent contracts called by the first transactions in the same execution stage are different, and shared data do not exist among the intelligent contracts. The intelligent contracts without the shared data are determined in advance, the first transactions are distinguished based on the intelligent contracts without the shared data, so that the first transactions are distinguished into different execution stages, parallel execution is realized for transactions in the same execution stage, the efficiency of parallel execution of the transactions is improved, and the accuracy of parallel transaction execution is improved.

Description

technical field [0001] The present invention relates to the field of financial technology (Fintech), in particular to a blockchain transaction execution method and device. Background technique [0002] With the development of computer technology, more and more technologies (such as blockchain, cloud computing or big data) are applied in the financial field. The traditional financial industry is gradually transforming into financial technology, and big data technology is no exception. However, due to The security and real-time requirements of the financial and payment industries also put forward higher requirements for transaction execution in the blockchain system in big data technology. [0003] At present, in order to ensure the transactional nature of the transaction, the blockchain system needs to make the transaction be executed serially, and it is completely serial; the specific process is to sort the transaction first, and then execute the smart contract with a single...

Problems solved by technology

[0006] However, in the DAG method in the prior art, it is necessary to manually fill in the mutually exclusive relationship (such as user account number, transfer address, etc.) for each transaction to determine the dependency graph between transactions, which affects the efficiency of parallel execution of transactions, and There is an error in filling in the mutual exclusion relationship, which leads to transaction execution conflicts and affects the accuracy of parallel execution transactions
