What is this new and exciting cryptography field called zero-knowledge cryptography? How is it related to trusted and confidential computing, and why do we need to rethink security because of it? This is what you’ll learn in this article. But first, who are we? We’re three cofounders: David, ex-Facebook security lead at Libra/Diem and author of the Real-World Cryptography book; Brandon, founding engineer of the Mina blockchain and ex-Pinterest/Facebook; and Gregor, tech lead of zero-knowledge framework SnarkyJS, and one of the winners of the largest zk competition ZPrize.
