[zapps-wg] Powers of Tau participation + zk proof question

[Andrew Miller]

Thank you so much for expressing your question in Camenisch-Stadler
notation! That makes it very clear what you're going for.

What hash function H do you have in mind, would SHA2 work? Also what group
G do you have in mind, secp256k1?

If so, I do not know of any existing implementation of secp256k1 operations
specifically in libsnark, so that would presumably be the biggest challenge.

I'd like to participate in the setup ceremony.

I also have an app I'd like to build using a zk-proof of knowledge of an
ECC private key. {(a) : A = a * G, B = H(a)}. Can anyone point me to good
resources on getting started?
