This paper proposes a verification and exchange method for cross-chain transactions of heterogeneous blockchains for electricity application scenarios and designs a chain-level cross-chain event verification mechanism. For a blockchain platform that requires cross-chain transactions, a Merkel-structured cross-chain event tree is systematically constructed with the collected cross-chain transactions in the generation stage of the block. The target blockchain platform verifies the credibility of cross-chain events based on the Merkel-structured cross-chain event tree and related credible proofs. Cross-chain events are captured through smart contract events, and cross-chain event Merkel trees and Merkel paths are constructed to achieve credible and rapid verification of cross-chain events. The cross-chain experiments are carried out in the main-side chain mode of electricity business scenario, and the integrity of cross-chain transaction is ensured by a cross-chain transaction consistency guarantee mechanism, so as to achieve the purpose of trusted circulation and secure transactions of electricity business data between different application chains.
