Abstract

The invention provides an under-chain processing method and device for a block chain task. The method is applied to a scheduling engine contained in an under-chain computing node, the under-chain computing node corresponds to a block chain node, the under-chain computing node further comprises a computing engine composed of a computing engine framework and a computing unit managed by the computing engine framework, and the method comprises the steps that cached historical block chain tasks are obtained after starting is completed, the historical block chain task is generated by the block chain node before the scheduling engine is shut down; initiating a state query request for the historical block chain task to the block chain node; and processing the historical block chain task in response to the query result returned by the block chain node indicating that the historical block chain task is in an uncompleted state.

Description

technical field [0001] The embodiments of this specification belong to the technical field of blockchain, and in particular, relate to a method and device for off-chain processing of blockchain tasks. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In the blockchain system, the data blocks are sequentially connected to form a chain data structure according to the time sequence, and a distributed ledger that cannot be tampered with and cannot be forged by cryptography. [0003] The blockchain tasks generated by the blockchain network can be processed by off-chain computing nodes, but in the process of executing the blockchain tasks, the off-chain computing nodes may be shut down for some reasons. In the related art, the off-chain computing node after the startup will continue to process the blockchain tasks that were being pr...
