Abstract

The invention provides a cross-chain interaction method for a block chain, and the method comprises the steps: a transmission chain initiates a cross-chain transaction, calls a send strategy in a smart contract, and generats a locked asset transaction TX1 in the transmission chain; and the notarist group performs signature processing on the locked asset transaction TX1, and when the signature proportion of the trader reaches the expectation and does not exceed the transaction invalidation time, the notarist calls a recive strategy in the smart contract, generates a cross-chain transaction TX2 corresponding to the TX1, and sends the cross-chain transaction TX2 to a receiving chain. According to the invention, cross-chain interaction is realized by using a notarist group mechanism and combining the smart contract, and cross-chain transaction between different block chains is realized. Compared with a traditional notarist mechanism, the use of the smart contract can ensure that the cross-chain transaction is carried out in a programmed manner according to a set rule, and the participation of multiple notarists also improves the reliability of the cross-chain transaction to a certain extent; and compared with a traditional method that cross-chain Hash locking is achieved only through an intelligent contract, coordination of notarians can be more efficient and is not limited by time.

Description

technical field [0001] The invention relates to the field of block chain cross-chain technology, in particular to a block chain cross-chain interaction method. Background technique [0002] As a decentralized distributed ledger, blockchain is widely used in finance, medical care, government affairs and other fields due to its characteristics of decentralization, non-tampering, anonymity, and traceability. However, the underlying blockchains of different applications are independent of each other, and their architectures and consensuses are different from each other, making trusted interaction between chains very difficult. 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] The exi...
