Hi @tokuryoo
as of now II is formally not a DID – as you’ve pointed out it is not registered as a DID-method. We’re currently using a DID format internally in the context of Verifiable Credentials, and are discussing the way forward, i.e. whether we’ll register something like did:icp:... or rather use II’s public keys in did:key:... method. We’ll share our thoughts in the coming weeks.
Cheers,
