Verum is a systems programming language with native formal verification: dependent types, SMT-backed refinements, and cubical HoTT alongside LLVM/MLIR AOT compilation (CPU + GPU), a zero-cost capability-based memory-safety model (CBGR, ~1 ns / check), native async, and a human-ergonomic syntax. Verification is gradual — write normal code, prove what matters — ending the false choice between "fast systems language" and "verifiable research language." Its applied layer, Mathesis, extends the approach from code to scientific theories themselves.
