【Abstract】With more and more in-depth research on blockchain core technologies such as consensus mechanisms, the overall performance of blockchain systems has been greatly improved. These dedicated blockchains form isolated information islands, and the lack of cross-chain interoperability seriously restricts the large-scale application of blockchain. Digital assets such as fungible and non-fungible tokens can flexibly model blockchain business scenarios, but how to combine digital assets to design cross-chain data model and operation mode remains to be studied. This paper proposes a cross-chain collaboration model and consistency maintenance method for digital assets. This method can capture the causal relationship between cross-chain operations and solve the conflict caused by concurrent cross-chain operations. While improving the responsiveness of cross-chain operation, the eventual consistency of cross-chain data is effectively maintained. Experiments have shown that this method does not depend on the network between chains and the delay of consensus, which has higher responsiveness.
