Bitcoin Core 31.1 Released With Chainstate and Privacy Fixes

Bitcoin Core officially released version 31.1 on July 8, 2026. The software is available for download, and the project’s official download page lists 31.1 as the latest version.

The update includes new features, bug fixes, performance improvements, and updated translations, according to the release notes. The published materials also identify fixes affecting chainstate database behavior and the -privatebroadcast feature.

Bitcoin Core releases are relevant to node operators because they maintain the software used to validate and relay activity on the Bitcoin network. Users should review the release notes and their own operating requirements before deciding whether to upgrade.

Fix for excessive chainstate database rewrites

Bitcoin Core 31.1 fixes an issue involving repeated large rewrites of the chainstate database. According to the release notes, the behavior caused excessive disk reads and writes.

Chainstate data is part of the local information a full node uses when validating the blockchain. The fix is therefore aimed at improving the software’s handling of this database activity rather than changing Bitcoin’s consensus rules.

-privatebroadcast IP address leak addressed

The release also fixes a potential IP address leak associated with the -privatebroadcast feature under certain conditions.

The release notes identify this as a privacy-related correction. The available evidence does not specify every affected configuration or condition, so operators using the feature should consult the official release documentation for implementation details.

Latest version available

Bitcoin Core’s official download page lists version 31.1 as the latest release. Alongside the identified fixes, the update contains general performance improvements and translation updates.

The release is a maintenance update with changes spanning reliability, resource use, privacy handling, and localization. It does not constitute financial advice or a recommendation to take any market action.
