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.

Hey reader! I haven’t posted in a while, but as this is my blog I’m contracted to talk about life events such as this one. I’ve joined O(1) Labs a bit more than a month ago to work on the Mina cryptocurrency. If you don’t know about Mina, check it out, it’s pretty cool: it uses recursive zero-knowledge proofs to compress a blockchain into a single proof of 11KB. I hope I got you intrigued! I want to say it is one of, if not the most, ambitious project in the space (but I’m biased). As I’m still relatively new there, I don’t have much to say besides that, but you can imagine that my posting will switch to more zero-knowledgy type of stuff very soon!
