Uses HTML5+RDFa[1] for visual representation... rest of it looks similar to
some Encrypted Data Vault[2] design choices... not to mention the tie-in to
Apple and Google push notification services (they own those push notification
service platforms, after all)... all kinda jumbled together as a point
solution for moving static credentials (with no suggestion to how the
cryptographic keys are moved)... some interesting design choices[3].

The charter seems to only focus on the transfer of bearer credentials:

https://github.com/dimmyvi/secure-credential-transfer/blob/main/charter.md

I'd expect that with that specification, you could argue that you support an
open ecosystem (as long as you ignore the push service centralization and the
fact that Apple/Google aren't going to allow credential export to just /any/
wallet)... but you get a handful of "trusted platforms" in each market and you
can avoid good chunks of anti-competition regulations.

Leader author is Dmitry Vinokurov -- His public Github profile[4] says:
"Dmitry is an engineer at Apple. There, he works on the server applications
for Apple Pay, focusing on areas including security, cryptography and
web-commerce."

I'll note that Mozilla's CTO also seems to have reviewed the documents and is
contributing to Charter text:

Seems like a point solution -- digital dead drop box for bearer credentials
that are encrypted to specific individuals. Very little overlap w/ VCs and the
protocols we're discussing here (but, would be good to keep our eye on this one).
