New BIP461 draft standardizes ECDSA signing to expose hidden key leaks

  • —BIP461 specifies a deterministic ECDSA signing procedure so independent signers can be compared
  • —Mismatched signatures for the same key and message hash suggest at least one signer is not compliant
  • —The standard caps signatures at 70 bytes in DER encoding, excluding Bitcoin's one-byte sighash flag
  • —Implementation requires no change to Bitcoin consensus rules
Why it matters: The proposal offers wallet users a shared benchmark for spotting deviations, but its value depends on compliant implementations and comparisons that expose secret keys.
