Halmos.Science
Community board for mathematics that provides machine-checked verification for proofs and computations
It is a community board for mathematics that solves the problem of unverified claims on forums where correctness relies on persuasion, by adding machine-checked verification for proofs and computations. It is for individual mathematics enthusiasts, students and researchers participating as consumers in an open community with a free tier. It is positioned against forums like MathOverflow, StackExchange and r/math by adding a second arbiter that cannot be argued with, where the server runs Lean, Sage, PARI/GP, Z3 and Python and marks kernel-accepted proofs.
