Full portfolioAbout this project
The Post-Quantum Signature Size Explorer makes PQC infrastructure tradeoffs tangible. NIST-standardized signature schemes like ML-DSA, Falcon, and SLH-DSA can be orders of magnitude larger than classical options, with real consequences for bandwidth, storage, and protocol design. Built for developers, security professionals, researchers, teams, and students navigating the quantum-safe transition.
Since launch, it has been referenced by the University of Messina's Quantum Computing & Information Systems Lab as a recommended resource within their "Quantum-Safe by Design" internship program, ranks in Google for PQC-related queries, and is actively used by audiences in the United States and China.
About the author
I work at the intersection of applied cryptography, blockchain security, and developer education. My consulting practice (Valens) covers PQC readiness assessments, smart contract and web security audits, and technical advisory for early-stage teams. I am a member of the IACR and an active contributor to Ethereum.org's developer materials. Tutorials I've written on calldata and transaction simulation are featured in their official resources.
