Bitcoin Core v32 completed its feature freeze on Aug. 20, with developers focused on bug fixes and optimization ahead of an expected October release. Galaxy Digital analyst Christine Kim said the upgrade adds parallel loading of previous transaction outputs for block verification, network-wide transaction rate limiting instead of per-peer limits, and fee estimation based on transaction data accumulated in the mempool. Parallel validation uses multicore CPUs and is designed to increase verification speed threefold. The revised rate-limiting approach is intended to improve node stability during transaction surges, while the mempool-based estimator aims to reduce cases in which required fees are calculated above actual levels. An official release date has not been announced, and the update does not include a network-wide protocol change.
