Universal Resolver

The Universal Resolver resolves Decentralized Identifiers (DIDs) across many different DID methods, based on the W3C DID Core 1.0 and DID Resolution specifications. It is a work item of the DIF Identifiers&Discovery Working Group.

See this blog post and this webinar for an introduction.

See https://dev.uniresolver.io/ for a DIF-hosted instance of the Universal Resolver that can be used for testing purposes. See Docker Hub for images.

Quick Start

You can deploy the Universal Resolver on your local machine by cloning this Github repository, and using docker-compose to build and run the Universal Resolver as well as its drivers.

git clone https://github.com/decentralized-identity/universal-resolver
cd universal-resolver/
docker-compose -f docker-compose.yml pull
docker-compose -f docker-compose.yml up

You should then be able to resolve identifiers locally using simple curl requests as follows:

You can also use an "Accept" header to request the DID document in a specific representation, e.g.:

curl -H "Accept: application/did+ld+json" https://dev.uniresolver.io/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw
curl -H "Accept: application/did+json" https://dev.uniresolver.io/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw
curl -H "Accept: application/did+cbor" https://dev.uniresolver.io/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw

If this doesn't work, see Troubleshooting.

Note that there is also a Universal Resolver frontend that can optionally be installed separately.
