FabricDG: A Transaction Conflict Optimization Solution for the Consortium Blockchain

As blockchain garners increasing attention, consortium blockchains are extensively integrated into enterprise-level systems. However, in high-concurrency scenarios, consortium blockchains using the EOV architecture face transaction conflict issues, resulting in decreased effective throughput. This article proposes FabricDG, an optimization solution addressing this by improving the EOV architecture through transaction dependency graph construction and parallel transaction scheduling. Experimentally, FabricDG outperforms baseline solutions, achieving over 4x higher throughput in low to medium transaction conflict rates and over 2x performance improvement in high conflict rate scenarios while maintaining an effective rate.
