Abstract: To address the shortcomings of decentralized authority management, difficult business expansion, centralized reading and writing, and weak transactionality between multiple contracts in complex application scenarios, a consortium chain multi-chain collaboration scheme for complex application scenarios is proposed. This scheme uses a blockchain gateway to manage user access rights, provides an inter-chain routing mechanism for dynamic scaling of logical chains, implements a read-write separation mechanism to improve performance, and employs a TCC-based transaction scheme to support multicontract transactions. Experiments and analysis results show that the proposed scheme effectively improves transaction throughput, and has better support for business dynamic expansion and multi-contract transactionality.
