Dentists, blockchains, novocain

 Xxx novocain xxx

Let’s begin by recapitulating the elements of the problem space. If I show up at the local practice in response to their dentist wanted ad on indeed.com there are three domains to consider. In the authorisation domain, I must present the appropriate qualification and the practice must be able to validate it. Of course, I must be able to demonstrate in the authentication domain that the qualification belongs to me. And although it is not at all necessary for the regular functioning of the practice, the identification domain must provide my “real” identity because of the rules of the medical world.

Let’s walk through these steps.

First, presenting the qualification.

Second, authenticating the qualification.

 

Third, linking the qualification to identity.
