Abstract

The invention provides a cross-chain information interaction method and system between block chains, a medium, equipment and an application, and solves a cross-chain scheme between different block chain projects. The cross-chain information interaction system comprises a first block chain, a relay block chain and a second block chain, wherein the first block chain comprises a first block chain account and a first cross-chain contract; the second block chain comprises a second block chain account and a second cross-chain contract; the first block chain, the relay block chain and the second block chain are all provided with collectors; cross-chain interaction time, the first blockchain account sends a cross-chain interaction request to the first cross-chain contract, a collector in the relayblock chain actively collects a cross-chain interaction request in the first cross-chain contract; after signature verification, the data is recorded on the relay block chain, a collector in the second block chain actively collects cross-chain interaction records on the relay block chain, sends a cross-chain interaction request to a second cross-chain contract, and the second cross-chain contractunlocks the mapped interaction data and transfers the interaction data to a second block chain account.

Description

technical field [0001] The present invention relates to the field of blockchain cross-chain, in particular to a method, system, medium, equipment and application for inter-blockchain cross-chain information interaction. Background technique [0002] The blockchain originated from Bitcoin. Since the birth of Bitcoin in 2009, thousands of blockchain public chains have been developed, and the number of cryptocurrencies based on various public chains has shown a blowout growth. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The blockchain is essentially a decentralized database, which is a series of data blocks associated with cryptographic methods. Each block contains the corresponding timestamp on the blockchain and all data transaction information that occurred . [0003] Among the many problems faced by the blockchain, the interoperability between b...
