It can be viewed at https://github.com/ZenulAbidin/bips/blob/master/bip-notatether-signedmessage.mediawiki.&#xA;&gt;&#xA;&gt; For those who want a quick summary, it defines a step-by-step process for signing and verifying messages from legacy, native/nested segwit, and taproot addresses. It does not define a new signature format itself, except in the case of Taproot. For those addresses, I have defined a signature format that has 1 byte header/recID, 64 bytes signature, and 32 bytes x coordinate of a public key. This is required to run the BIP340 Schnorr verify algorithm using only the signature - and the header byte is added for backwards compatibility. Otherwise, it completely integrates BIP137 signatures.&#xA;&gt;&#xA;&gt; I am planning to move that format to its own BIP as soon as possible, in lieu that it is unacceptable to define formats in an Informational BIP.&#xA;&gt;&#xA;&gt; Please leave your comments in this mailing list.
