Wallet Credential Format Grid - October 2020

DIF Interoperability WG

Note: For entertainment purposes only, all claims self-attested and not based on interop testing or conformance suites! This was crowd-sourced and unconfirmed anecdotal research for educational/exploratory purposes, and never edited as a deliverable of the working group. –juan caballero, 10/2022

Note: Similar effort is now ongoing under the OpenWallet Foundation. See Digital Wallet and Agent overview

We (the DIF Interop WG and guests) are trying to get a ballpark notion of which types of credentials each "wallet" can HOLD (be issued) and PRESENT (use to generate VPs). Nits:

• By "wallet," we are including custodial wallets and agents, all software that can hold credentials under the control of their holder and present credentials on behalf of their holder
• For the purposes of this document, verifying and consuming these VCs but "translating" them or storing them in another format is out of scope (although that might be a valuable thing to look into later!).
• Similarly, we are not looking too closely at how interoperable each wallet is with which issuers or how foreign/far-afield they are– that's a nit to be picked another day! We can add more columns later if people find that useful.

Instructions:

• If you have intimate knowledge of the roadmap/dev team of a wallet you feel qualified to speak about publically,
  • please try to fill in each credential format's columns in your wallet's row using the following legend ONLY (no text)
  • if you would like to add text, please do it as a hackmd footnote like this^[1].
• If you do not have such knowledge and authority, but you know someone who does, please forward this URL to them!

LEGEND:

Y = Our wallet currently can hold and present these cred formats in a way that we feel is 100% conformant S = Soon (already in development) P = Partial support:

• some specified features missing, and/or
• specified features implemented in an off-spec way
• no decision yet on when/whether to address the above. if decided, use PR or PX.

PR = Partial support, the rest is on our roadmap PX = Partial support, and no plans to implement the rest and/or conform to spec R = Roadmapped but not currently in development N = No decision X = Planning NOT to support this format ! = None of your business, DIF! ? = No definitive information could yet be confirmed or denied from governing organization. If a cell contains another symbol and a ?, consider it an unconfirmed rumor!

THE MAIN EVENT

Notes from discussion 10/7/20

Ideas for future columns or future charts

• Human versus non-human subjects/holders?
• Agents versus wallets– bracketable for now?
• Nomenclature: stop calling it anoncreds2, Juan!
