Re: Question From HPEC re SSI Wallets

Yes, thanks for that mention, Kim. I had a feeling as I pressed send that I
was forgetting something obvious.

A subtlety: simply backing up and restoring data to wallets is not
particularly hard (though you have to get the crypto right). However,
standardizing the semantics of the data such that backed up data will be
usable by a different wallet vendor IS. That's one of the benefits that the
universal wallet task will help with.

FWIW, I believe that Andre Kudra at Esatus has expressed an interest in
collaborating on this topic.
