I Want COVID-19 Certificates But I Don't Want a DID
- TYPE: Session DATE: Tuesday, May 12, 2020 TIME: 10:50-11:10
The W3C Verifiable Credentials Data Model is being used as the basis for creating standardised COVID-19 certificates of different types: vaccination, test and immunity certificates.
As the W3C Recommendation clearly states, "DIDs are a new type of identifier that are not necessary for verifiable credentials to be useful. Specifically, verifiable credentials do not depend on DIDs and DIDs do not depend on verifiable credentials." So why are most implementers insisting on building COVID-19 certificates with DIDs and blockchains? This talk will provide an answer to this question, and show how COVID-19 certificate eco-systems can be built without recourse to DIDs or blockchains.
