Deploy HOL Light to Europe — John Harrison 🇬🇧 (Cambridge → Intel), the Minimalist HOL Theorem Prover that Proved IEEE 754 Floating-Point Correct and Formalised the Kepler Conjecture, on EU Infrastructure in 2026
Deploy HOL Light verification workloads to EU servers in minutes. sota.io is the EU-native PaaS — GDPR-compliant, managed PostgreSQL, zero DevOps. HOL Light by John Harrison 🇬🇧 (Cambridge PhD 1996, supervisor: Lawrence Paulson) — a minimalist HOL system in ~400 lines of OCaml (INRIA 🇫🇷). Used at Intel to formally verify IEEE 754 floating-point transcendental functions (sin, cos, exp, atan, ln). The Flyspeck project (2014): Hales' Kepler conjecture formally proved in HOL Light + Isabelle. EU AI Act Art. 9. CRA 2027. Free tier.
