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

10-20s proving time is more than fast enough for me. I'm going to dig through the gadgetlibs to get a feel for what it'd take to implement this, but it's been a long time since my last algebra class. On Wed, Jan 3, 2018 at 3:06 PM Andrew Miller wrote: > Yeah! It's 2018

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

This is about the point where my math and libsnark knowledge runs out :) My usecase is specifically cryptocurrency related, so I'm mostly interested in curves that are used by cryptocurrency signature algorithms. E.g. secp256k1 (Bitcoin and its kids), ed25519 (Sia, Stellar, and a few others).

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

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
