Not absence of
evidence—proof of
absence.

Testing can demonstrate the presence of bugs, but never their absence. Formal verification produces mathematical proof that software behaves correctly across all inputs, all states, all execution paths.

The software industry has accepted a fundamental limitation for decades. We are building the infrastructure to remove it—making exhaustive, machine-checked proof as accessible as writing a unit test.

01.
Correctness by construction

Software that is proven correct before it ships, not discovered incorrect after deployment.

02.
Institutional infrastructure

A neutral foundation stewarding verified tools as public goods across the entire software ecosystem.

03.
Democratized formal methods

Eliminating the PhD requirement. Automated proof generation that any developer can use.

HOL4 · Verified Compiler Theorem
(* Compiler correctness for Vyper → EVM *)

Theorem compile_correct:
   (src : vyper_program)
    (evm : evm_bytecode)
    (state : execution_state),
  
  compile src = Ok evm
  
  semantics_vyper src state
  = semantics_evm evm state

(* Corollary: no reachable state violates safety *)
Theorem no_exploit_path:
  exploit_state.
    reachable evm exploit_state  ¬violates_safety exploit_state
Proof

QED
Why now
  AI-generated code is
   accelerating total software
   output—and total risk surface.

  $2.2B lost to smart contract
   exploits in 2024 alone.

  Regulatory forcing functions:
   EU AI Act, MiCA, FDA SaMD.

  Verification cost down from
   $1,000/line to near-zero.

Three pillars of
verified infrastructure.

The Foundation for Verified Software operates as a neutral institutional home for formal verification research, open tools, and the ecosystems that depend on them. We are the academic and public-interest counterpart to commercial verification efforts.
