tl;dr: Pedersen commitments[^Pede91Comm] are one of the most important cryptographic primitives for a beginner to understand, in my opinion.

tl;dr: Notes on our current use of Groth16 for Aptos Keyless and how we might improve upon it. Should have applications to anonymous payments, confidential assets, zkVM proof wrapping etc.

tl;dr: The 1st multivariate polynomial commitment scheme based on a non-trivial generalization of KZG.

tl;dr: (Almost?) all of the cryptography deployed on Aptos. For users, for developers and for general security.

tl;dr: We fix up our previous non-ZK, univariate DeKART scheme and also speed up its verifier by trading off prover time. This is joint work with Dan Boneh, Trisha Datta, Kamilla Nazirkhanova and Rex Fernando.

tl;dr: This is how it all started: folks wanted to “encrypt.” What does that mean?

tl;dr: For now, this page gathers some resources on FRI[^BBHR18FRI].
