BNB Chain Says Reth Tests Show 40% Throughput Gain on BSC

BNB Chain said it has optimized the Reth client for BNB Smart Chain (BSC), with internal tests showing 40% higher throughput than an earlier configuration using Geth’s TrieDB. Initial synchronization results also showed Reth running 40% faster than the current BSC-Geth client, while migration for validators remains in development.

The two percentages compare different measures against different baselines: throughput against the earlier TrieDB configuration, and synchronization speed against BSC-Geth. BNB Chain said the TrieDB integration enabled trie prefetching and changes to block-production scheduling. The work also addressed state-root computation and data persistence.

Earlier changes included parallel sparse-trie processing and adjusted build settings. BNB Chain said those changes reduced block insertion, execution and validation latency during full-node synchronization. However, the client’s 95th-percentile validation latency remained higher than BSC-Geth’s.

Reth can handle both historical and live synchronization, but validator migration is still being developed. BNB Chain’s long-term target for the client is 1G gas per second with block times below 750 milliseconds. Planned work includes EVM JIT and ASM Hash optimizations; no timeline for those changes was provided.
