AxiomCode — Features & Qualities

Natural Language to Formally Verified Code
Domain: axiom-code.com
Version: 0.1.0
License: Proprietary — see LICENSE
Dependencies: Zero (pure Python stdlib + cffi)

Executive Summary

AxiomCode is the world's first zero-dependency, zero-trust, cryptographically secured system that converts natural language descriptions of algorithms into mathematically proven-correct Python and C code. Every generated artifact comes with a verifiable proof certificate, HMAC signature, and tamper-evident audit trail.

Built for commercialization. Designed to surpass Python and agent-based LLM code generators by providing mathematical certainty instead of probabilistic guesses.

Core Features

1. Natural Language to Verified Code

  • Describe algorithms in plain English — no programming knowledge required
  • Automatic Lean 4 specification generation via local or cloud LLMs
  • Formal proof search with Pantograph + Goedel-Prover integration
  • Code extraction to C binaries and Python packages
  • Machine-checked proofs where verification succeeds — every artifact carries an honest verification_status ("verified" only when a proof assistant actually checked the proof; "unverified"/"failed" otherwise). AxiomCode never claims a proof it did not check.

2. Minimal External Dependencies

  • Pure Python stdlib — no pip packages to install (except cffi for bindings)
  • No attack surface from third-party libraries
  • No supply chain vulnerabilities — no requests, no Flask, no SDKs
  • HTTP via stdlib http.client — direct API calls to llama.cpp, OpenAI, Anthropic
  • Crypto via stdlib hashlib, hmac, secrets, plus the audited cryptography package for Ed25519 signatures (publicly verifiable certificates require asymmetric crypto — hand-rolling it would be worse)

3. Zero-Trust Security Model

  • Every output independently verifiable — no blind trust in any component
  • Cryptographic proof certificates — Ed25519-signed attestations of provenance and integrity, with honest per-artifact verification status
  • Binary signing — every C binary and Python package is signed and verifiable
  • Tamper-evident audit log — hash-chained entries detect any modification
  • Encrypted key store — PBKDF2-derived keys, encrypted at rest
  • Secure sandbox — isolated execution with restricted environment
  • Rate limiting — token bucket prevents API abuse

4. Multi-Backend LLM Support

Backend Type Default Model Speed Quality
llama.cpp Local qwen2.5-coder:14b Fast Good
Mistral Local mistral:7b Fast Good
OpenAI Cloud gpt-4o Medium Excellent
Anthropic Cloud claude-sonnet-4 Medium Excellent
  • No SDKs — direct HTTP calls, zero dependency overhead
  • LLM response caching — persistent cache reduces cost and latency
  • Automatic retry with exponential backoff
  • Fallback chain — if local model fails, suggests cloud alternatives

5. Cryptographic Proof Certificates

Every generated algorithm comes with a signed certificate containing:

  • Hash of the Lean 4 specification
  • Hash of the proof term
  • Hash of the compiled C binary
  • Hash of the Python package
  • HMAC signature for authenticity
  • Key ID for verification
  • Timestamp for non-repudiation

Certificates are independently verifiable — anyone can verify the certificate without trusting AxiomCode.

6. Interactive Proof Visualization

  • 2D Port Graph — Incredible Proof Machine style block diagrams
  • Force-Directed Graph — D3.js interactive dependency graphs
  • 3D Spatial Layout — Three.js-ready architecture for future expansion
  • Self-contained HTML — no server required, works offline
  • Click-to-inspect — view any proof step's Lean tactic

7. Version Management & Data Persistence

  • Automatic version tracking — every installation knows its version
  • Upgrade migration — v1 → v2 → vN with automatic data transformation
  • Downgrade support — vN → v2 → v1 with data preservation
  • Automatic backups — every migration creates a restorable backup
  • Rollback capability — one command to restore previous state
  • Migration history — complete audit trail of all version changes
  • Data integrity validation — verify all data matches current schema
  • Multi-step migration paths — BFS-based pathfinding through version graph
  • History retention — all historical data preserved across version changes

8. Commercial Licensing System

  • Root key pair — cryptographic signing key kept secret by AxiomCode
  • Hardware binding — licenses tied to machine fingerprint
  • Offline verification — no phone-home needed
  • 3 tiers — Community (free), Pro ($49/mo), Enterprise (custom)
  • Revocation support — compromised licenses can be invalidated
  • Portable licenses — optional non-hardware-bound licenses

9. Comprehensive CLI (15 Commands)
