To address the issue of untrustworthy behaviors resulting from malicious attackers exploiting security vulnerabilities within smart contracts in the consortium blockchain system, this study introduces a trusted verification mechanism of smart contract behavior for consortium blockchain to conduct trusted verification for contract behavior integrity. Firstly, the proposed approach takes the system call as the smallest behavior unit and describes the historical behavioral state with the behavior sequence based on system calls. Subsequently, on the premise of ensuring the trustworthiness of contract code release and the execution environment, it performs trusted verification according to predefined behavioral rules during contract execution. Finally, a theoretical analysis of this mechanism is carried out, and an experimental evaluation is conducted in the Hyperledger Fabric environment. Results demonstrate that the proposed method can effectively achieve the trusted verification of smart contract behavior and ensure the credibility of behavior within the life cycle of smart contracts.
