As another of the FROST authors, I am interested in the FROST draft moving forward and of course would be involved in working on it.


We have an implementation of FROST in Rust; note that this implementation will have minor changes as we receive feedback from our presentation at SAC [1] and elsewhere.


https://git.uwaterloo.ca/ckomlo/frost/


We have also been in discussion with those at NIST who are organizing the threshold signatures standardization effort, and will be participating in the upcoming workshop.


Note that FROST can also be used when keys are generated via a central dealer as well as via a DKG (Distributed Key Generation) protocol. We have both variants in our implementation, even though we specify only the DKG variant.

Multiple implementations already!  That's great!

I suppose I should just say for the record that as one of the authors of
FROST, I of course am also interested in seeing it move forward, and
would be involved in working on it.
