In April 2026, I gave a talk in Cannes about comparing and benchmarking post-quantum digital signature schemes.
Choosing a signature scheme involves trade-offs between key and signature sizes, signing and verification speed, security assumptions, and implementation complexity. I am interested in understanding those trade-offs through working code and reproducible measurements.
The awesome-pq-signatures repository contains implementations and benchmarks for schemes including Falcon, Dilithium, SPHINCS+, and several hash-based and code-based alternatives. It is where I collect the code behind this work and continue exploring the practical differences between signature schemes.
Personally, my favorite post-quantum digital signature scheme is Falcon. I also like LeanSig, Lean Ethereum's XMSS-based signature scheme. I made an experimental BLAKE3 version of LeanSig, replacing Poseidon with BLAKE3 to speed up key generation. The repository includes the implementation and benchmarks.
