Dear CFRG,

We have a new version of draft-irtf-cfrg-vrf, specifying Verifiable Random
Functions (VRFs).

https://datatracker.ietf.org/doc/draft-irtf-cfrg-vrf/

This revision updates the elliptic curve VRF (ECVRF).  Key changes include

1) Add a new Curve25519 ciphersuite that uses elligator2 for hashing
2) Add domain separation for hashing
3) Make nonce selection deterministic

Here's a slide deck summarizing the update, that we will present at
IETF102.  We also have very specific places where we are seeking feedback
from the RG, which are summarized in the slides. Please have a look.

Thanks,
