A Universal Resolver is an identifier resolver that works with any decentralized identifier system, including Decentralized Identifiers (DIDs).
See this blog post and this webinar for an introduction.
See https://uniresolver.io/ for a publicly hosted instance of a Universal Resolver.
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:
curl -X GET http://localhost:8080/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw
