CISV: A Cross-Blockchain Information Synchronization and Verification Mode

Although the advanced technology stack of blockchain leads to the prosperity of its applications, the underlying mechanism of blockchain interoperability remains stagnant. Targeting at the efficiency and verification problems of existing cross-blockchain mechanisms, we design a Cross-Blockchain Information Synchronization and Verification (CISV) mode. In CISV, Cross-chain Information Synchronization (CIS) uses the design of touch block to provide high synchronization rate within low network delay, while Cross-chain Information Verification (CIV) applies ECC cryptography algorithm and Secure Multi-party Computation (SMC) to guarantee the accuracy and privacy of cross-chain information. Experiments executed on three mainstream blockchains (Ethereum, Hyperledger Fabric, and EOS) show that CISV has a reliable performance in blockchain interoperability with strong expansibility.
