Abstract

The application provides a conflict detection method, device, node device and storage medium, which belong to the technical field of blockchain. The method includes: in response to the waiting instruction, creating at least two tasks for the block of the target batch indicated by the waiting instruction, and one task is used to indicate one of the target batches to be chained in the blockchain system A plurality of processing logics of the block; in response to an execution instruction for the target batch, execute at least two tasks, and during the execution process, control the simultaneous execution of the same processing logic included in the at least two tasks; according to the execution of the at least two tasks As a result, the conflict status of the target lot is determined. By setting a corresponding task for a block in the target batch to be chained in the blockchain system, and executing the same processing logic included in each task at the same time, it can be determined according to the execution result whether there is a block between each execution logic. Conflicts, and then discover the security risks in the blockchain system.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a conflict detection method, device, node device and storage medium. Background technique [0002] In the blockchain system, in order to meet the high-performance requirements of the business, the blockchain service will carry various concurrent optimization processes in the processes of transaction reception, packaging, verification, submission, and storage. Since there may be transactions with upper and lower dependencies between blocks, these transactions cannot be submitted at the same time, otherwise conflicts will occur. For example, transaction A: user a pays X yuan to user b, transaction B: user a pays Y yuan to user c, and transaction A occurs before transaction B, then user a should actually have Z-X-Y yuan remaining. If transaction A and transaction B are submitted at the same time, user a will have Z-X yuan left after executing transaction A, and use...
