Elaborating on the Trusted Digital Web definition of a Wallet…

A Wallet is a digital store for credentials, keys, and master secrets that is local, secure, and personal to each and every Agent. It resides on the same node/node cluster an Agent’s Service Endpoint is hosted on. A Wallet is a specialization of a Generic Credential Repository.

Yes. I prefer the following 3 terms for backing stores for a Trusted Digital Agent:
- Smart Wallet (workflow-enabled credential ledgers (subledgers))
- Key Ring
- Master Secrets Store
Reference: https://hyperonomy.com/2021/06/28/trusted-digital-web-8-layer-architecture-reference-model-tdw-arm/

Wrt Linked Data Structures, I prefer concepts that people (developers especially) can readily identify with e.g Credential Ledgers, Hashes, Signed Hashes, Notarization, a simple and easy-to-understand and code against Credential data model, Credential modeling and Agent modeling language, auto code generation ...assuming your goals are to be the first fully decentralized object platform with more than a million app developers.
Bold? ...a bit. The above is how the Trusted Digital Web platform works (almost). 🙂

Thanks for the diagram, Michael, it's very helpful.

I'm not seeing much in there that hasn't been contemplated by the VC data
model with Linked Data Signatures (which support chained signatures -- which
you're demonstrating one use of here). That said, having the use case
diagrammed is quite useful.

My suggestion is to get away from the "Wallet" language when talking about the
general ecosystem in the same way that we got away from blockchain/DLT when
talking about the Verifiable Data Registry.

Where entities store their Verifiable Credentials isn't always going to be a
wallet. I suggest the more general term should be:

Verifiable Credential Repository

OR just

Credential Repository

I'm sure folks may want to bike shed that term. I suggest that "Wallet" or
"Holder" is already confusing people (the most recent perma-thread is a great
example) and we should get our terminology straight before launching into the
next standardization cycle.
