Description

Category-of-one cryptographic primitive ready for commercial deployment.

WHAT IT IS:
- Degree-2 algebraic hash function designed for zero-knowledge proof systems.
- Only known construction at the theoretical maximum algebraic efficiency (eta = 1.0, Boeuf-Perrin 2025 ceiling).
- Runs natively in Circle STARK provers (StarkWare’s Stwo) where the industry-standard Poseidon2 is #[ignore]d by the prover.
- USPTO provisional patent filed March 2026. Priority rights + full technical documentation transferred; buyer handles non-provisional filing within the 12-month window.
- BUSL-1.1 licensed (auto-converts to Apache 2.0 in April 2030).

WORKING IMPLEMENTATIONS:
Five major proof backends, all bench-green: Halo2, Plonky3, Stwo, Noir (stdlib-tests pass), Circomlib. Cross-implementation bit-for-bit parity pinned at the KAT level.

MEASURED PERFORMANCE:
- Halo2 / KZG / BN254: 2.51x faster Merkle-depth-20 prove time vs Poseidon2; scales to 4.81x at depth 512.
- Circom / Groth16 / BN254: 3.48x fewer R1CS non-linear constraints at 128-bit matched security (66 vs 240).
- Noir / UltraHonk / BN254: 1.96x fewer gates per Merkle-depth-20 permutation under custom gate, 1.47x faster prove (measured end-to-end with patched nargo + Barretenberg).
- Plonky3 / BabyBear / FRI: 4.11x smaller Merkle proof size; 744ms p50 recursive-verifier prove at STANDARD.
- Stwo / M31 / Circle STARK: runs at state widths t=16 and t=32 where Poseidon2 does not compile (category of one).

SECURITY:
- 1TB PractRand (no statistical anomalies).
- 160/160 BigCrush (full suite clean).
- 9 attack classes analyzed: interpolation, CICO, Grobner basis, FGLM, higher-order differential, algebraic degree, field saturation, sponge indifferentiability, alternating-sponge BBB.
- Paper read by AO cryptographers.
- Planned ToSC 2026 submission (1 June deadline). Sale closes before publication to preserve buyer IP control.

MARKET CONTEXT:
The zero-knowledge proof market is projected at $5-10B by 2030. Hashing accounts for 50%+ of proving cost in STARK systems and 20-40% in SNARK Merkle and commitment-heavy workloads.

This primitive cuts hash cost by 2-5x at matched security across every major backend, and is the only algebraic hash that runs natively in Circle STARK provers where the industry standard is currently blocked entirely. Next-generation provers can only use a degree-2 hash. This is currently the only one on the market.

A 2-5x hash reduction maps to 25-40% total prove-cost reduction in STARK systems; low-double-digit percent in hash-heavy SNARK circuits. For any production L2 or zkVM with meaningful proving infrastructure spend, that is seven-figure annual savings per integration.

WHY FOR SALE:
Independent inventor and researcher. I built the cryptography, filed the patent, wrote the implementations. What I lack is time and industry connections to bring this to production integration at scale.

The right buyer has L2 infrastructure access, ZK protocol relationships, or proving-service distribution. Natural targets for licensing/acquisition: StarkWare, Aztec, Cartridge - any hashing-heavy ZK protocol.

ASKING: offers above $250K USD (in XMR at spot). Full IP transfer: patent assignment with provisional + priority rights, all five production implementations, reference code, security analysis, paper.

Payment via escrow, will be specified in the sale agreement.
