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.

Vlogging attempts

blog

I tried to record a few short videos these last months (eventhough the last one is quite long). You might enjoy some of them:

I dropped the “vlog” on the last one (that’s 45min long!) so you don’t feel like you’re wasting your time listening to me. The second one is a bit shameful to me because my habit of working out has dwindled down dramatically and I’m now fighting to preserve it while enduring the long winter of New York :D
