Server-Based Verifiable Data Registry

A server-based implementation of verifiable data registry based on swift-express-graphql. It mainly uses Javascript Object Signing and Encryption (JOSE) for DID and derived functionalities.

Cryptographic Algorithm

Functionality	Algorithm	Curve
Authentication	ES256	P-256
Assertion Method	EdDSA	Ed25519

Feature

• Issue DIDs.
• DID/Key persistence.
• DID/Key resolving by REST and GraphQL.
• Administration.

Quickstart

By Docker Compose

1. Duplicate .env.example as .env and configure environment variables;
2. Configure Dockerfile and docker-compose.yml;
3. Compose and run containers.

docker compose up -d

By Docker
