- Bitcoin Core 32 causes PSBT v2 import failures on older nodes.

- Market impact: Bitcoin down 4.25% in 24 hours amid broader market decline.
The latest 
Bitcoin Core 32 update has introduced a technical issue affecting the multisig signing process on nodes running mixed versions of the software. According to reports, the update causes a failure when importing Partially Signed Bitcoin Transactions (PSBT) v2 files on older nodes.
While the update includes this compatibility issue, the RPC option still defaults to creating v0 files, which adds to the inconsistency. This means that users relying on multisig transactions could face disruptions if they operate in environments with mixed software versions.
The problem highlights a broader challenge in Bitcoin's ecosystem, where updates to core software can create interoperability issues. This is particularly relevant for institutional users and exchanges that rely on multisig setups for security.
In the current market context, Bitcoin is trading at $81,051, down 4.25% in the last 24 hours and 1.10% over the past week. The overall crypto market cap stands at $2.78 trillion, with a Fear & Greed index of 68, indicating 'Greed' among investors.
The issue underscores the importance of maintaining consistent software versions across nodes, especially for users who depend on multisig functionality. As the Bitcoin network continues to evolve, stakeholders will need to monitor future updates for similar compatibility concerns.
