😳 Hello you!
I'm David Wong. I work at zkSecurity on zero-knowledge proofs and on general security of advanced cryptographic primitives, I'm also the author of the book Real-World Cryptography and the host of the podcast Two And A Half Coins. I was previously a cryptography architect working on the Mina cryptocurrency at O(1) Labs, and the security lead on the Diem blockchain (formely known as Libra), working from Novi (Facebook). Before that I was a security consultant at the Cryptography Services (of NCC Group). You can find more about what I do on my blog cryptologie.net.
