Bitcoin Improvement Proposal (BIP) 461 was merged into the BIPs repository on September 16 and is currently in draft status. The proposal aims to make compliant ECDSA signatures reproducible by defining a generic signing procedure for the existing ECDSA signature scheme. This means that independent compliant signers should produce identical signatures for the same private key and message hash, establishing a baseline to detect deviations that might conceal key leaks. The implementation of this proposal does not require a consensus change, as it operates under existing Bitcoin consensus rules. By comparing signature differences, it can be determined whether a signer is following BIP461, which helps identify potential malicious firmware behavior, although a mismatch alone cannot directly prove malice or theft.
