[DID 기술 분석] Universal Resolver

서로다른 블록체인 기술 기반의 DID 호환을 가능하게 하는 방법

1 Universal Resolver 대두 배경

DID를 구현하는 방식은 BTC, ETH, Hyperledger Indy 등 기존의 블록체인 기술뿐만 아니라 자체 블록체인 기술을 활용한 방식으로 구현이 가능하므로 현재의 DID 프로젝트는 각각 개별적인 생태계를 구축하고 있으므로 다양한 DID 플랫폼의 출시가 예상된다. 그러므로 DID 보유자와 서비스 제공자 입장에서는 많은 유저 확보와 서비스의 공급이 필요하게 되므로 DID의 확산 관점에서는 DID의 Interoperability 가 대두됨으로써 DID의 Universal Resolver가 필요하게 됨.

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
