Re: Goals and Requirements for DID Method Standardization?

My challenge for long-lived VCs is that likely they require more than
digital signatures, such aa additional proofs. Until we have some better
choices for quantum-resistant signatures (a tough nut to crack) that means
at minimum publicly provable time stamps with no phone-home or correlation
(I currently use
https://opentimestamps.org and am investigating very large Sphinx
hash-based co-signing).

My example use case is that I have over a hundred students that got their
MBA in Sustainable Systems from an accredited small college, circa 2009.
The school was then BGI.edu, become Pinchot.edu, merged with Presidio.edu,
acquired by Dominican College. Multiple states, multiple accreditation
bodies. But they should be able to have a credible MBA digital certificate
for life. They can’t currently.

Other long-term scenarios are IP transfers (not only copyright & trademark
but trade secrets), fiduciary and healthcare directives, marriage related
(a particular challenge given same-sex marriage being illegal in many
countries), etc. Even many peer credentials need to survive a peers death.

Biggest challenge in this category will be physical real property, or
property mixed physical with digital (art in particular). Both will need to
be provable 70+ years, well into a quantum-capable future.
