Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and 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.

Libra/Diem's second life as Aptos posted February 2022

As some of the readers of this blog know, I worked for two years at Novi (Facebook) on the Diem (formerly known as Libra) cryptocurrency. The project was recently dismantled, most likely due to regulator unwillingness to help a non-government backed cryptocurrency reach millions of people at scale.

Today, a group of 17 ex Novi/Diem engineers and researchers announced Aptos, presumably a fork of Diem. From what I understand, this means that a state-of-the-art blockchain that has been pushing the envelop in terms of innovation, security, and performance, and that's been in development for the last 4 years, now has a path to launch.

I'm guessing that we're going to see the typical proof-of-stake approach being implemented (unlike Diem's proof of authority) as well as a revamped set of smart contracts (written in Move) to govern the new blockchain. Besides that, the blockchain was already in a solid shape a year ago so I don't foresee any major changes.

Congratulation to the new team :) this is exciting.

Well done! You've reached the end of my post. Now you can leave a comment or read something else.
