We've been busy implementing crypto with it, but you can check our talk or the list of closed PRs. Off the top of my head, stuff we added:
-
new field arithmetic implementation that's faster than -donna, filled in missing field ops (sqrt, invsqrt etc), uniform variable-base scmul…
-
…multiscalar multiplication (uniform and vartime), precomputation for generic fixed-base scalar mult, scalar inversion, Decaf/Ristretto, …
-
…Ristretto flavor elligator / hashing to the curve / rand point gen, rangeproofs with parallel verification, a schnorr zkp compiler, etc.

You should check it out, ed25519-dalek might be useful, since it seems faster than the implementation in Ring.
-
There are quite a few paths forward to make *ring*'s EdDSA and X25519 faster. It will be a little while before we see which one we pick.
-
I did notice that you left *ring*'s EdDSA verification off the graph. Why? Also, what about the X25519 performance comparison?
-
Just because it wasn't in the crypto-bench crate — the only reason we included it was to give perspective on the donna/dalek numbers.
