Re: DID or CID

Hi Steve et al.,

I believe this is what used to be the Controller Document draft spec. My
high level take is that CIDs filter the best parts of the DID spec, leaving
behind some of the baggage - notably the need for new resolvers and
DID-method incompatibility.

DIDs account for generic registration (notably blockchain networks); but if
the world ends up using did:web, we don't gain anything from paying the
price for this DID abstraction. Instead of describing the resolver in the
abstract, the CID spec just describes where and how to place the necessary
cryptographic elements, resolving with classic HTTP.

FWIW I did a quick piece on this a while back when I first heard of it:
