PEAQ DID Resolver

This package provides methods to resolve a Decentralized Identifier (DID) from the peaq blockchain.

It supports the proposed Decentralized Identifiers spec from the W3C Credentials Community Group.

It requires the DID Resolver library, which is the primary interface for resolving DIDs.

DID method

DID Document

A minimal DID Document might contain the following information:

{
  "@context": [
    "https://www.w3.org/ns/did/v1"
  ],
  "id": "did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB",
  "controller": "did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB",
  "authentication": [
    "did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB#keys-1"
  ],
  "verificationMethod": [
    {
      "id": "did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB#keys-1",
      "type": "Ed25519VerificationKey2020",
      "controller": "did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB",
      "publicKeyMultibase": "z6Mkke5f4w4df5vLnW92jbxYy4Z3cayFD9XuegRS1TCnAB3x"
    }
  ],
  "service": []
}

Resolving a DID document

The resolver presents a simple resolver() function that returns a ES6 Promise returning the DID document.

import { Resolver } from 'did-resolver'
import { getResolver } from 'peaq-did-resolver'

// getResolver() accepts a DID Resolver server url
const peaqResolver = getResolver("wss://wsspc1-qa.agung.peaq.network")

const didResolver = new Resolver({
    ...peaqResolver
    //...you can flatten multiple resolver methods into the Resolver
})

didResolver.resolve("did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB").then(doc => console.log(doc))

// You can also use ES7 async/await syntax
;(async () => {
    const doc = await didResolver.resolve("did:peaq:5E1WsjiPHvPW5LdhL4h53TTc58YLGDpLeLi6jW8E6ypLeRtB")
    console.log(doc)
})();
