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.

Today, along with my two other cofounders Gregor Mitscha-Baude and Brandon Kase we are launching www.zksecurity.xyz an auditing platform for zero-knowledge applications.

Smart contracts have been at the source of billions of dollars of loss (see our previous project https://dasp.co). Nobody is sheltered from bugs. ZK smart contracts will have bugs, some devastating. Let’s be proactive when it comes to zkApps!

In the coming month we’ll be posting more about the kind of bugs that we have found in the space, from ZKP systems’ bugs to frontend compiler bugs to application bugs. If you’re looking for real experts to audit your ZK stack, you now have the ones behind zkSecurity.

We’re a mix of engineers & researchers who have been working in the smart contract and ZK field before you were born (jk). On top of that, we’ve also been in the security consulting industry for a while, so we’re professionals ;)

Stay tuned for more blogposts on http://zksecurity.xyz and reach out to me if you need an audit :)

Also, the launch blogpost is much more interesting than this one. Go read it here: Private delegated computation is here, and there will be bugs!
