DID

This is a work in progress. See https://gitlab.com/groups/minds/-/epics/211 for more information about what we are working on.

The Minds DID

In order to give every Minds user a DID, we have opted to introduce the did:web method. Other methods may be considered in the future.

An example of a DID:

{
  "@context":"https://www.w3.org/ns/did/v1",
  "id":"did:web:feat-2292-did.minds.io:mark",
  "verificationMethod":[
    {
      "id":"did:web:feat-2292-did.minds.io:mark#key-1",
      "type":"Ed25519VerificationKey2020",
      "controller":"did:web:feat-2292-did.minds.io:mark",
      "publicKeyMultibase":"mwU0pSAjd7CQ7lXyr+9IlkXU1Oycj8NFH/AoIhBNQPpE="
    }
  ],
  "authentication":[
    "did:web:feat-2292-did.minds.io:mark#key-1"
  ]
}

How it works

See https://w3c-ccg.github.io/did-method-web/.

Resolver example

did:web:minds.com:mark -> https://minds.com/mark/did.json

Linking other DID's

We are currently working on this section

The DID Spec includes the alsoKnownAs property. This can be used to link multiple DID's together. For example:

did:web:minds.com:mark:

{
  ...
  "alsoKnownAs": [ "did:ethr:0x177fd9efd24535e73B81E99e7f838cDeF265e6Cb" ],
}

did:ethr:0x177fd9efd24535e73B81E99e7f838cDeF265e6Cb

{
  ...
  "alsoKnownAs": [ "did:web:minds.com:mark" ],
}

As both DID documents above reference each other, we can safely assume the intent to link the DID's.

Verification and Authentication

The DID Spec allows for optional verification and authentication properties.

Minds.com may sign entities on users behalfs using the DID keypairs. These keypairs should be considered as temporary credentials and may be regularly rotated.
