Bitcoin Core 32 Wallet Change Can Break Multisig Signing With Older Nodes
(3 hours ago) · 1 source · Summarized by CryptoBipto
A change introduced in Bitcoin Core version 32 can cause multisig signing to stall when co-signers are running older versions of the software. The issue has been identified, but a fix has been deferred to a future patch release rather than being included in the current version.
WHY IT MATTERS
Think of a multisig wallet like a safe deposit box that needs two or more keys held by different people to open. Bitcoin Core is the main software people use to operate on the Bitcoin network, similar to how a web browser lets you access the internet. When one keyholder updates their software to the newest version (version 32) but another keyholder is still using an older version, the two versions do not communicate properly during the signing process, and the transaction gets stuck. This does not affect the security of anyone's funds — the Bitcoin is still safe — but it can temporarily prevent people from moving their money until everyone is on a compatible version or a fix is released. For newcomers, this is a good reminder that software updates in crypto can sometimes introduce unexpected compatibility issues, and coordination among participants matters.
