Overview of VC / DID / JSON-LD Interoperability Plug Fest

Thursday 20A

Convener: Anil John

Notes-taker(s): Melanie Nuce

Tags for the session - technology discussed/ideas considered: multi-vendor interoperability, DIDs, VCs, standards

Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps:


US Department of Homeland Security Silicon Valley Innovation Program (SVIP)

http://lists.w3.org/Archives/Public/public-credentials/2020Apr/0198.html
Not an R&D program; goal is to incubate projects that will eventually be implemented by Government Agencies in production

Solutions to prevent forgery and counterfeiting of certificates and licenses Goal is to move paper-based processes to interoperable digital processes Focused on:

Issuance, validation and verification of certificates licenses and attestations
Storage and management of certificates, licenses and attestations
Consolidate decentralized and derived PIV credentials

Security, privacy and interoperability: foundational principles; leveraging open APIs Projects to incorporate (as much as possible) the following components from W3C: DIDs, VCs, JSON-LD Product Focus Areas:

Raw Material Imports (Timber, Steel, Oil)
Permanent Resident Card (digital issuance)

Why are DIDs important to this process: DIDs provide assertion of sameness (prove you are talking to the same person) All participants must prove interoperability across multiple implementations It is not enough to “talk about” interoperability; you have to DO IT Interoperability levels being assessed

Wallet
Issuer
Verifier

Challenges to demonstrating interoperability

Tension between “interop” vs. one-way of doing something; the difference is whether multiple companies can utilize a set of tools vs. just one
For example, use of CHAPI (Credential Handler API) test plan, which has been extremely helpful
Test suite: http://github.com/w3c-ccg/vc-examples/tree/master/plugfest-2020

Work going on to support Zero Knowledge Proofs across multiple implementations (Tobias and Kyle were mentioned) DHS looking for a competitive ecosystem of diverse solution providers Critical to build on top of an interoperable framework, no matter what platform each company chooses Interoperability should not be underestimated SVIP has been a great forcing function to drive the priority There is a potential to test interoperability between companies in the SVIP cohort and those that are outside. DHS to confer with cohort participants to determine feasibility
