Abstract

Abstract: This paper provides a method and system for establishing and communicating cross-chain alliances between blockchains. The method for establishing the cross-chain alliance includes: obtaining communication requirements of each communication node in multiple blockchains, each node establishing a cross-chain alliance and configuring identity certificates and transaction certificates and establishing cross-chain smart contracts.The blockchain cross-chain communication method includes: obtaining a communication request by using each blockchain in the cross-chain alliance established above, and establishing a node smart contract for each node; if a communication request is initiated, performing an endorsement policy verification on the communication request, and then performing the full sequence signature verification and data consistency verification, when the communication request is verified, the communication between the nodes is implemented according to the cross-chain smart contract.
