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.

Disco: whitepaper

blog

I already wrote a lot about Disco:

Today, I released the white paper that introduces the construction. Check it out on ePrint.

disco paper

It’s a combination of everything I’ve talked about, plus:

  • some experimental results on embedded devices done by Matteo Bocchi and Ruggero Susella
  • some preliminary results on formal verification with Tamarin Prover

I unfortunately did not have the time to complete the formal verification of several important lemmas. But I am hopping that I can achieve this in a later paper. The formal verification code is on github and anybody is welcome to help :)
