Credentials Community Group

The mission of the W3C Credentials Community Group is to explore the creation, storage, presentation, verification, and user control of credentials. We focus on a verifiable credential (a set of claims) created by an issuer about a subject—a person, group, or thing—and seek solutions inclusive of approaches such as: self-sovereign identity; presentation of proofs by the bearer; data minimization; and centralized, federated, and decentralized registry and identity systems. Our tasks include drafting and incubating Internet specifications for further standardization and prototyping and testing reference implementations.

What’s in a Wallet? The recap

On July 7 and 14, 2020, The CCG hosted two sessions where we asked people from inside and outside the community to answer the question, “What’s in a Wallet?” You can review the meeting notes and listen to the audio below:

“What’s in a Wallet?” as answered by…

As you can see, there are a lot of interpretations for what is in a wallet. We hope you find these presentations and perspectives mind-opening and keep in mind the desires of your end users when you develop digital identity wallets.
