Hi Chris, thank you very much for your detailed answer.

Makoto, part of “ownership” includes not having ongoing dependency on the issuer. In the case of educational credentials, a student shouldn’t have to depend on their past schools to share their own official records of those achievements. Academic records represent the past, but they have value for use in the future.

The case of insurance feels a little different. By definition the individual depends on that Issuer persisting for their insurance to work. And I don’t see why anyone would want to preserve their proof of insurance long after that Issuer is gone?

That being said, I do think a case can be made for using Ethereum or private blockchains to create an audit trail that makes it harder to change than a simple database. While the audit trail would not be truly immutable, many things don’t need that highest level of security. I hope this opinion helps, good luck!
