Trust Resolution Library Development

[lotharking]

Description

The goal of this issue is to develop a library responsible for trust resolution.

Currently, verifiable credential management in Credo-TS relies on a manually maintained trust registry. Each record is created without verifying the authenticity of the corresponding DID document, meaning there is no actual trust resolution mechanism in place.

While Credo provides an ecosystem that considers trust-related aspects, the primary focus of this library may not necessarily be on validating credential types. However, it is crucial to establish a method for determining trust for services interacting with the system.

Proposed Solution

• Implement a resolve method that:
  • Accepts a DID as input, along with optional parameters (to be defined).
  • Resolves the DID document to determine its properties and validate its authenticity.

Use Case

Both Hologram (the mobile app) and the Service Agent 2060 Service Agent are clients of this library.

• The goal is to enable a user agent (using Hologram) to verify that the Service Agent is a trusted service through this library.

Next Steps

• Define the optional parameters required for the resolve method.
• Determine the best approach for DID document resolution.
• Implement and test the method to ensure proper trust validation.

Resolver

Used with DidResolverService from Credo Core to call the resolveDidDocument method.
