Re: Datashards and Secure Data Hubs... how to achieve convergence?

I should add one more component. Where does Alice store the prescription
and the prescriber store her copy for her records? We know the prescriber
has a DID wallet but that may not be the preferred long-term (10+ years)
storage. Also, it would help adoption if Alice can use something she
already has for her records storage. Something like google drive or just
whatever backs up the smartphone.
