Re: Introducing the Bitcoin Ordinals DID Method

Hi Brian, congrats on your DID method, and thanks for having privacy &
security sections as the DID spec requires. If you're looking for
"inscription" methods, you could build off of what we've done for did-doge
(which is basically built on pre-segwit bitcoin):
