DIF Presentation Exchange 2.0.0

This is Rust a library for the DIF Presentation Exchange 2.0.0 specification developed by the Decentralized Identity Foundation.

Description

This specification addresses the need for a standardized way to demand and submit proofs in identity systems. It introduces a Presentation Definition format for Verifiers to express proof requirements and a Presentation Submission format for Holders to describe proof submissions.

Key Points:

• The specification is format-agnostic, supporting various Claim formats as long as they can be serialized as JSON.
• It is also transport-envelope agnostic, allowing the conveyance of data via different methods like OpenID4VP, OpenID Connect, DIDComm, or Credential Handler API.
• The goal is to promote unified procedures and reduce redundant code.
• The specification does not define transport protocols or specific endpoints but encourages their use in other projects that define such mechanisms.
