Abstract

The invention provides a cross-chain interaction method of blockchain, including sending a chain to initiate a cross-chain transaction, invoking a send strategy in a smart contract, and generating a locked asset transaction TX1 on the sending chain; The transaction TX1 is processed for signature. When the signature ratio of the trader reaches the expectation and does not exceed the transaction expiration time, the notary calls the receive strategy in the smart contract to generate the cross-chain transaction TX2 corresponding to TX1 and send it to the receiving chain. The present invention utilizes the notary group mechanism and combines smart contracts to realize cross-chain interaction, and realizes cross-chain transactions between different blockchains. Compared with the traditional notary mechanism, the use of smart contracts can ensure that cross-chain transactions are carried out in accordance with established rules, and the participation of multiple notaries also improves the reliability of cross-chain transactions to a certain extent; Using smart contracts to achieve cross-chain hash locking, the coordination of notaries can be more efficient and not limited by time.

Description

technical field [0001] The invention relates to the technical field of blockchain cross-chain, in particular to a cross-chain interaction method of blockchain. Background technique [0002] As a decentralized distributed ledger, blockchain is widely used in finance, medical care, government affairs and other fields due to its features of decentralization, immutability, anonymity, and traceability. However, the underlying blockchains of different applications are independent of each other, and their architecture and consensus are different from each other, which makes it very difficult to trust the interaction between chains. With the continuous development of blockchain technology, the demand for inter-chain interaction continues to increase. It is urgent to establish an efficient cross-chain interaction method to break the situation of blockchain information islands and realize information sharing and value between different blockchains. Intercommunication. [0003] Exist...
