Abstract

The embodiment of the invention relates to the field of Fintech, in particular to a method and device for monitoring a smart contract in a block chain, which is used for improving the safety of the smart contract. The method comprises the steps of obtaining a transaction request; calling the corresponding smart contract according to the transaction request; during the process that the smart contract executes the transaction request, if it is determined that the called operation code is an operation code needing to be paid attention to, judging whether the operation code needing to be paid attention to meets the error condition of a monitoring rule or not; and if yes, outputting an abnormal result of the called operation code according to the monitoring rule, and executing a blocking operation for the operation code.

Description

technical field [0001] The invention relates to the field of technology finance (Fintech), in particular to a method and device for monitoring smart contracts in a block chain.
