NFT DID Method specification

Discussion for CIP-94

This is awesome. What other components are needed to enable an NFT to own and control a Ceramic doc? A DID provider?

[oed]

There needs to be an implementation of a DID Resolver. This is the first need.

Then possibly a separate provider. Although it would be nice if you could just use the provider of the DID that is the controller of the NFT DID. I think this should be possible.

[codynhat]

Ah ok. I've been trying to figure out the difference between a provider and resolver. Is this right?

DID Resolver -> General DID standard for resolving a DID document from a DID
DID Provider -> Basically EIP-2844? So something that allows a DID to authenticate, sign, and decrypt?

So if a NFT DID resolver existed we could go from a did:nft -> DID document -> If the controller of the DID document is did:key or did:3, use an existing DID provider?

[oed]

Yes exactly @codynhat 👍

[codynhat]

Cool. Thanks for helping me understand! This is definitely something we are interested in and may be an area we can contribute.

@codynhat Hacked together a quick prototype of the resolver.

Feel free to contribute! Will likely pick it back up when I have more free time, but don't think I'll get much longer today :)

[codynhat]

Awesome! I'll take a look.

Is this proposal still active? I was wondering if the DID should not include the chain-id to identify on which chain the NFT resides.

[oed]

@RobertOttSWITCH it does include the caip-2 chain_id!
This proposal is active and has an experimental implementation here: https://github.com/ceramicnetwork/nft-did-resolver

Oh, perfect, I didn't get that in the first place, thanks.

Is there any plan for the specification and implementations to support Polkadot/Kusama + parachains NFTs?

[Amirjab21]

Can smart contracts that currently own NFTs also update the data stream or does it only work with user wallets?
