Fine-grained control strategy for high-concurrency transactions in the consortium chain Hyperledger Fabric

Hyperledger Fabric is a consortium chain framework that is widely used at home and abroad. When conducting business with Fabric technology, high-concurrency transaction conflicts are often encountered. To optimize the high concurrent transaction processing performance of Hyperledger Fabric, this paper proposes a targeted fine-grained control strategy, relying on the Dynamic Priority Reordering - Chain Code Cache mechanism (DPRC-Cache) framework and attribute-based Access Control (ABAC). Experiments show that fine-grained resource access control can effectively reduce the transaction conflict rate. Meanwhile, the optimized transaction sorting mechanism plays a positive role in improving the overall throughput of the system.
