Blockchain Parallel Mechanism Based on Transaction Process Decoupling for Complex Digital Asset

To enhance blockchain throughput, various parallel mechanisms have been proposed, yet many are ill-suited for complex assets due to the intricacy of their states and properties, resulting in longer dependency paths and reduced efficiency. This paper introduces a parallel mechanism tailored for complex assets by distinguishing between consensus and execute nodes and decoupling the transaction processing flow for independent scalability. It utilizes a multi-way Merkle tree to create independent state trees for assets and employs the MPT for a global state tree. Additionally, an efficient parallel state submission process is designed to improve state commit efficiency and support parallel transaction processing with an asynchronous workflow. The delayed submission strategy further eliminates blockages in the commit phase, enhancing system throughput. Experimental results show that this mechanism outperforms existing blockchain parallel mechanisms, significantly boosting state commit efficiency while ensuring high scalability.
