The  Verifiable Claims Working Group  invites implementations of an updated Candidate Recommendation of  Verifiable Credentials Data Model 1.0 .  Credentials  are a part of our daily lives; driver’s licenses are used to assert that we are capable of operating a motor vehicle, university degrees can be used to assert our level of education, and government-issued passports enable us to travel between countries.
