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.

Algorand's cryptographic sortition

blog

There are several cryptocurrencies that are doing really interesting things, Algorand is one of them. Their breakthrough was to make a leader-based BFT algorithm work in a permissionless setting (and I believe they are the first ones who managed to do this). At the center of their system lies a cryptography sortition algorithm. It’s quite interesting, so I made a video to explain it!

PS: I’ve been doing these videos for a while, and I still don’t have a cool intro, so if you want to make me a cool intro please do :D
