Overview

DID (Decentralized Identifier) is a new type of identifier that is globally unique, resolvable with high availability, and cryptographically verifiable. DIDs are typically associated with distributed ledgers because they are designed to function without a central authority or single point of control.

This implementation focuses on the Sovrin network, leveraging the capabilities provided by the Hyperledger Indy SDK.

Features

• DID Creation: Generate a new DID and associated verification key.
• DID Resolution: Resolve a DID to retrieve its associated DID Document.
• DID Update: Update the verification key associated with a DID.
• DID Deactivation: Deactivate a DID, rendering it unusable for further operations.
• Active Check: Verify if a DID is currently active.
• Resolver Support: Get supported resolvers for the given DID methods.

Prerequisites

• Node.js and npm/yarn.
• Access to an instance of a Hyperledger Indy network.
• Familiarity with DIDs and the Hyperledger Indy SDK.

Usage

Here's a basic guide on using the provided Sovrin DID methods:

1. Initialization:

    const didMethod = new SovrinDIDMethod(ledgerName, genesisPath, passKey, idName);

2. DID Creation:

   const didWithKeys = await didMethod.create();

3. DID Resolution:

    const resolutionResult = await didMethod.resolve(did);

4. DID Update:

   const isSuccess = await didMethod.update(didWithKeys, newKey);

5. DID Deactivation:

   const isDeactivated = await didMethod.deactivate(didWithKeys);
