Universal Resolver

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.

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:

curl -X GET  http://localhost:8080/1.0/identifiers/did:sov:WRfXPg8dantKVubE3HX8pw
curl -X GET  http://localhost:8080/1.0/identifiers/did:btcr:xkrn-xzcr-qqlv-j6sl
curl -X GET  http://localhost:8080/1.0/identifiers/did:v1:test:nym:3AEJTDMSxDDQpyUftjuoeZ2Bazp4Bswj1ce7FJGybCUu

curl -X GET  http://localhost:8080/1.0/identifiers/did:stack:v0:16EMaNw3pkn3v6f2BgnSSs53zAKH4Q8YJg-0
curl -X GET http://localhost:8080/1.0/identifiers/did:erc725:ropsten:2F2B37C890824242Cb9B0FE5614fA2221B79901E
curl -X GET http://localhost:8080/1.0/identifiers/did:hcr:0f674e7e-4b49-4898-85f6-96176c1e30de
