Will the Bitcoin Core 32.0 software update be released on October 10?

Developers are set to release the Bitcoin Core 32.0 software update on October 10, 2026. The update includes a security fix for a wallet-related vulnerability that has existed since version 24.0.

Why it matters

The release addresses a security flaw that permitted authenticated users to execute commands through wallet names. Additionally, the software features a new fee estimator designed to lower recommended transaction costs more efficiently during periods of declining network congestion.

The update enables multithreaded transaction retrieval using a default of eight threads. Four commands for partially signed transactions will now default to version 2.

The players

Bitcoin Core

Bitcoin Core is the open-source software project that provides the reference implementation of the Bitcoin network protocol.

The details

The update improves database performance by utilizing multiple threads for transaction retrieval during block checks. An audit uncovered that 16 REST connections could spike memory usage to 3 gigabytes, a significant increase from the standard 46 megabytes.

Timeline

  1. September 14, 2026: Bitcoin Core 32.0 entered final testing.

  2. October 10, 2026: The scheduled release date for the update.

The Tech Race

This update addresses a security vulnerability that has been present since the Bitcoin Core 24.0 release. It marks a continued effort to optimize node memory and transaction efficiency against historical software debt.

Users will benefit from more accurate fee estimations, helping them avoid overpaying for transactions during congestion. Operators of nodes should note the memory usage specifications to ensure their hardware can support the new multithreaded retrieval defaults.

The takeaway

Users should prepare for the October 10 update to ensure their wallets are protected against the identified command-execution vulnerability. Maintaining updated software is essential to benefit from the performance optimizations in transaction retrieval and fee estimation.
