HECO DID

About

This project implements the W3C's DID standard into the HECO Chain and is inspired from the Uport project

Decentralized identifiers (DIDs) are a new type of identifier that enables verifiable, decentralized digital identity. A DID identifies any subject (e.g., a person, organization, thing, data model, abstract entity, etc.) that the controller of the DID decides that it identifies.

HECO needs to have a DID service as many DeFi services require identification.

Deploying the DID registry

You can skip this step if you want and use the contract we deployed on 0x4C74827FA00DD44C4eC1fC80C6EC2eB37fFf8fC9

To deploy a new DID registry :

yarn install
truffle compile
truffle migrate --network testnet

Lanching the frontend

To start the frontend :

yarn start

The frontend will automatically connect to the DID registry. If the registry has not been correctly deployed, you will see the error HecoDidRegistry contract not deployed to the detected network..

The first step is to create a DID for your address. Click 'Create DID'. You should see a new DID as follows :

did:hecor:0x4C74827FA00DD44C4eC1fC80C6EC2eB37fFf8fC9

This represents the did scheme with hecor method (for HECO Registry) and method-specific identifier (your eth address).

You can now sign claims and get a JWT that a third party can verify. For this, enter any claim in json format, i.e :

{name : "Aymeric"}

Metamask will open to sign the transaction. You will then obtain your signed JWT.
