cryptography, security, and random thoughts

Hey! I'm David, cofounder of zkSecurity, research advisor at Archetype, and author of the Real-World Cryptography book. I was previously a cryptography architect of Mina at O(1) Labs, the security lead for Libra/Diem at Facebook, and a security engineer at the Cryptography Services of NCC Group. Welcome to my blog about cryptography, security, and other related topics.

Are you into finding bugs and learning ZK? Here's a challenge for you

blog

Spent some time to write a challenge focused on GKR (the proof system) on top of the gnark framework (which is used to write ZK circuits in Golang).

It was a lot of fun and I hope that some people are inspired to try to break it :)

We’re using the challenge to hire people who are interested in doing security work in the ZK space, so if that interests you, or if you purely want a new challenge, try it out here: https://github.com/zksecurity/zkBank

And of course, since this is an active wargame please do not release your own solution or write up!
