Bitcoin developers propose standard to detect wallet private key leaks

Bitcoin developers have proposed a new standard, BIP-461, to detect covert private key leakage during wallet signing, CryptoSlate reported. The proposal centers on standardizing ECDSA signatures so any compliant signer using the same private key and the same message would produce the same result. If a signature differs from the standard output, it would make it easier to check whether hidden behavior aimed at leaking the private key was involved in the signing process. The proposal does not require changes to Bitcoin’s existing consensus rules, allowing related wallets or signing software to adopt it without a network upgrade.
