Thanks Orie,
I missed the call this morning unfortunately.
 I heard you made a shout out to GHP and our work at ToIP
<https://wiki.trustoverip.org/pages/viewpage.action?pageId=73790>.
 Right now we have 10 different drafting groups on the key challenges
outlined in the blueprint outline.

 One of those groups - is focused on credentials formats and exchange. We
were faced with a sort of overwhelming and confusing choice landscape and
needed to signal to the market a clear way to move credentials from issuer
to holder and holder to verifier.  I'm really happy that we had 3 1.5
sessions at IIW and have broad alignment to get to one simplified protocol
that builds on the best of what is out there.

 We will be pointing to this work and seeking to drive adoption of the
results of this effort over the summer.

 - Kaliya
