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.

Some news from founding a startup (zkSecurity)

blog

I guess I don’t post that much about the startup I cofounded more than a year ago, so this is a good opportunity to release a short note for the curious people who read this blog!

I posted a retrospect on the main blog of zkSecurity: A Year of ZK Security, but more time has passed since and here’s how things are looking like.

We’ve had a good stream of clients, and we are now much more financially stable. We’ve managed to ramp up the team so that we stop losing work opportunities due to lack of availability on our side (we’re now 15 engineers, interns included). Not only is the founding team quite the dream team, but the team we created are made of people more qualified than me, so we have a good thing going on.

Everybody seems to have quite a different background, some people are more focused on research, others are stronger devs, and others are CTFs people wearing the security hat. So much so that our differing interests have led us to expand to more than just auditing ZK. We now do development, formal verification work, and design/research work as well. We also are not solely looking at ZK anymore, but at advanced cryptography in general. Think consensus protocols, threshold cryptography, MPC, FHE, etc.

Perhaps naming the company “zk”security was a mistake :) but at least we made a name for ourselves in a smaller market, and are now expanding to more markets!

That’s it.
