Ethr-DID

A Scalable Identity Method for Ethereum Addresses

uPort is a self-sovereign digital identity platform---anchored on the Ethereum blockchain. The uPort technology primarily consists of smart contracts, developer libraries, and a mobile app. uPort identities are fully owned and controlled by the creator---independent of centralized third-parties for creation, control or validation.

Using the Ethr-DID library, you can:

  • Create and manage keys for DID identities

  • Sign JSON Web Tokens

  • Authorize third parties to sign on a DID's behalf

  • Enable discovery of service endpoints (e.g. decentralized identity management services)

The Ethr-DID library conforms to ERC-1056 and supports the proposed Decentralized Identifiers spec from the W3C Credentials Community Group. These allow for Ethereum addresses to be used as fully self-managed Decentralized Identifiers (DIDs), as a result, you can easily create and manage keys for these identities. This library also allows you to sign standard compliant JSON Web Tokens (JWTs) that can be consumed using the DID-JWT library.
