Hello All,
Some people have asked for more detail about the vc-demo we published
the other day: https://github.com/digitalbazaar/vc-demo
**It is currently possible to:**
- Generate a Ed25519 or Secp256k1 keypair.
- The public key material and a controller document will
automatically be uploaded as a gist to your github.
- Sign a VC document of your own design, or using the provided sample.
- Verify the signed VC.
- The verifier retrieves controller and key documents from public gists.
**Node.js Source Code**
- https://github.com/digitalbazaar/vc-js-cli
- https://github.com/digitalbazaar/vc-js/tree/node-12
- https://github.com/digitalbazaar/ecdsa-secp256k1-signature-2019
- https://github.com/digitalbazaar/secp256-key-pair
- https://github.com/digitalbazaar/jsonld-signatures/tree/node-12
A sample signed VC looks like this. You should be able to verify this
credential yourself using the vc-js-cli tool.
