CMSCEF: A Cross-chain Mechanism based on Smart Contract Execution Framework

Aiming at the cross-chain interoperation difficult problem between isomorphic or heterogeneous blockchain systems, we propose a cross-chain mechanism based on the cross-chain smart contract execution framework. Firstly, a cross-chain smart contract execution framework is proposed to weaken the blockchain properties of relay chains. Secondly, a reliable cross-chain scheme based on the Pedersen VSS and VRF is designed for the framework. Lastly, we conduct multiple sets of experiments on the proposed cross-chain mechanism. The experimental results proved that the proposed cross-chain mechanism is able to execute cross-chain transactions efficiently and securely with realistic feasibility. Its cross-chain interoperation TPS is about 8 times higher than that of the traditional relay chain platform BitXHub on average, and about 82% higher than that of TCIP.
