FastFabric: Scaling Hyperledger Fabric to 20,000 Transactions per Second

Understand

Blockchain technologies are expected to make a significant impact on a variety of industries.

• However, one issue holding them back is their limited transaction throughput, especially compared to established solutions such as distributed database systems.
• In this paper, we re-architect a modern permissioned blockchain system, Hyperledger Fabric, to increase transaction throughput from 3,000 to 20,000 transactions per second.
• We focus on performance bottlenecks beyond the consensus mechanism, and we propose architectural changes that reduce computation and I/O overhead during transaction ordering and validation to greatly improve throughput.
