Bitcoin Core 32 enters final testing with faster validation, fee changes and security fixes
Bitcoin Core 32.0 has entered its final testing phase ahead of an expected October 10 release, introducing improved fee estimation and faster block validation through multi-threaded processing. The update also includes critical security patches for a command-injection vulnerability and a memory-exhaustion flaw discovered during an AI-assisted audit.
Why it matters
These updates enhance the efficiency and security of the Bitcoin network's foundational software, ensuring nodes can operate more reliably and cost-effectively for users and service providers.
The first release candidate for Bitcoin Core 32.0 was tagged on Sept. 14, starting the final testing cycle before developers aim to release the finished version on Oct. 10, according to the project's release schedule .
Bitcoin Core lets a computer independently check transactions and blocks against Bitcoin's rules rather than relying on another service. Version 32 does not change those rules.
Bitcoin Core currently estimates how much a user should pay for a transaction largely by looking at the fees attached to transactions that made it into previous blocks. Version 32 adds a second estimator that looks at transactions currently waiting to be confirmed.
