摘要

Hyperledger Fabric is a leading permissioned blockchain framework for enterprise use, known for its modular design and privacy features. While Hyperledger Fabric provides robust mechanisms for configurable consensus and access control, it encounters significant challenges in sustaining high transaction throughput and minimizing rejection rates under heavy workloads. We propose a dependency-aware execution model (Code for our proposed framework is available here: ) that: (a) Flags transactions as dependent/independent during endorsement, (b) Prioritizes independent ones in block construction, (c) Embeds a DAG per block to capture dependencies, and (d) Executes transactions in parallel at commit.
