Hey! I'm David, a security engineer at the Blockchain team of Facebook, previously a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Algorand's cryptographic sortition posted September 2019

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

Well done! You've reached the end of my post. Now you can leave me a comment :)

Hey David, is there any change that you can use Algorand technology at FB or Libra at some point? Thanks!
