BNB Chain boosts internal test throughput by 40%, pushes for validator migration within the year

BNB Chain plans to begin migrating existing validators to BSC-Reth by the end of 2026, following internal tests that showed roughly 40% higher throughput than its prior TrieDB-based configuration after integrating Reth 2.5.1. In the same benchmarks, block write latency came in at 71.6 milliseconds at p95, 34.9% below BSC-Geth, while execution latency was 56.5 milliseconds at p95, a 35.5% reduction. The chain disclosed the performance work and benchmark results in a blog post, though it noted the throughput and latency figures use different baselines and reflect internal testing rather than a measured 40% gain on the BSC mainnet. The results matter because they signal a possible path to higher capacity and lower latency for one of the largest smart-contract chains as it prepares a validator client overhaul. What to watch next is whether those internal gains hold up in production as validators begin the BSC-Reth transition ahead of the end-2026 target.
