Web5 Credential Issuance Protocol

This package provides a DWN protocol for credential issuance. See protocol/credential-issuance.ts for the protocol, and the accompanying schemas directory for individual schemas

The protocol

This project defines a protocol that uses Credential Manifests to define the credentials required to get other credentials.

A credential issuer provides one or more manifests defining credentials needed to apply for other credentials.

A credential applicant can then send a Credential Application to the issuer.

The issuer can reply with a Credential Response fulfillment including one or more credentials, or a denial including reasons why the credentials were not sufficient. It may also optionally respond with an invoice that must be paid before the request is fulfilled.

Use

// issuer side
import {
  credentialIssuerProtocol,
  manifestSchema,
} from "@web5/credential-issuance-protocol";

// example use in protocol query
const { protocols } = await web5.dwn.protocols.query({
  from: did,
  message: {
    filter: {
      protocol: credentialIssuerProtocol.protocol,
    },
  },
});

// applicant side
import {
  credentialApplicantProtocol,
  manifestSchema,
  presentationSchema,
  responseSchema,
} from "@web5/credential-issuance-protocol";

// example use in write
const { record: applicationRecord, status: createStatus } =
  await web5?.web5.dwn.records.create({
    store: true,
    data: presentationResult.presentation,
    message: {
      recipient: issuerDid,
      schema: presentationSchema.$id,
      dataFormat: "application/json",
      protocol: credentialApplicantProtocol.protocol,
      protocolPath: "application",
    },
  });
