H33-74

74 bytes. Any computation. Post-quantum attested. Forever.

32 bytes anchored · 42 bytes portable proof

Post-quantum cryptography and fully homomorphic encryption increase size and complexity. H33-74 keeps the trust layer fixed at 74 bytes for encrypted computation, authentication, and verifiable systems.

Post-quantum cryptography for encrypted computation, authentication, and verifiable data—without exposing plaintext or requiring infrastructure changes.

H33 is a post-quantum cryptography platform combining FHE (fully homomorphic encryption), zero-knowledge proofs, and quantum-resistant authentication into a single API.

Why Fully Homomorphic Encryption Cannot Be Signed — And How H33-74 Solves It

The Problem

  • FHE computes on encrypted data
  • Signature systems sign plaintext
  • Decrypting to sign exposes data
  • Signing “inside” FHE is impractical
  • Production systems hit a trust boundary

What H33-74 Changes

  • Commits to the result without exposing plaintext
  • Post-quantum signed (3 independent families)
  • Fixed 74-byte persistent footprint
  • Chain-agnostic, transport-agnostic
  • Independently verifiable
data encrypted compute H33-74 signed result verify anywhere

What happens when AI has no cryptographic accountability

TRADING
A trading agent executes a $50M order and claims it received different instructions.
MEDICAL
A medical AI recommends a treatment but can't prove what data it was given.
LEGAL
A legal AI drafts a contract — the output is modified before the lawyer sees it.
FRAUD
A fraud detection system is fed manipulated inputs and produces a clean result.
AUTONOMOUS
An autonomous system causes harm and points to the previous agent in the chain.

Every multi-agent AI pipeline in production operates on trust. That trust has no cryptographic foundation. H33-74 changes that.

H33-74

The H33-74 Primitive

Every H33 engine exports trust through the same primitive: H33-74.

Fixed

74 bytes no matter what

Portable

Moves through APIs, storage, devices, ledgers

Post-Quantum

Built for family rotation and long-lived verification

Independent

Verification does not depend on trusting H33

Your data never leaves encryption. The computation happens inside it. The result is post-quantum signed at the moment it's produced. The attestation is 74 bytes regardless of size.

Not compression. Commitment.

VERIFIED ON BITCOIN MAINNET — APRIL 14, 2026
Transaction: 7f8d9ef2...b028b4a7 — Taproot P2TR + OP_RETURN. Standard Bitcoin. No soft fork. No new opcodes. Independently verifiable by any full node worldwide.
74 bytes wears a lot of hats — Address, Packet, FHE Proof, PQ Seal, Chain Commit, Credential

Same 74 bytes. Six simultaneous roles. All networked.

Post-Quantum Authentication and Encrypted Computation API

One API integrates encrypted computation, proof generation, post-quantum signing, and verification into a single production pipeline.

FHE

Compute on protected data

ZK

Prove correctness without exposure

BIO

Match encrypted identity signals

PQ

Attest outputs under PQ signatures

All four export trust through H33-74.

AI Blind processes your data without ever seeing it. H33-74 attests the result without decrypting it.

Quantum Migration Is Not Optional

Classical public-key systems are on a migration clock. H33 is built for the systems that have to survive that transition.

Harvest Now, Decrypt Later

Nation-states are capturing encrypted traffic today. When quantum computers arrive, they decrypt everything retroactively. Intelligence agencies have confirmed this is happening.

Every Classical Key Is Vulnerable

Shor's algorithm breaks RSA, ECDSA, and Diffie-Hellman. Your TLS certificates, API auth, database encryption, and VPN tunnels. NIST finalized post-quantum standards in 2024.

Data Shelf Life

Cryptographically relevant quantum computers are expected by 2028–2032. Data encrypted today has a 5–7 year shelf life. Federal PQC migration deadline: 2030.

Frequently Asked Questions

What is post-quantum cryptography?

Post-quantum cryptography (PQC) uses mathematical problems that quantum computers cannot solve efficiently — unlike RSA and ECC, which Shor's algorithm breaks. H33 implements NIST's finalized standards: ML-KEM (FIPS 203) for key encapsulation and ML-DSA (FIPS 204) for digital signatures. Every H33 API call is post-quantum end-to-end.

Is fully homomorphic encryption fast enough for production?

H33's BFV engine runs encrypted biometric matching at 35.25 microseconds per authentication — 2.21 million per second sustained on Graviton4. The optimization stack includes Montgomery NTT, Harvey lazy reduction, and NTT-domain fused inner products.

What is harvest now, decrypt later?

Adversaries are capturing encrypted data today to decrypt once quantum computers mature (estimated 2030-2035). If your authentication tokens or session keys use RSA or ECC, they're already at risk. H33's entire pipeline uses lattice-based cryptography that remains secure against quantum attacks.

How do I add post-quantum encryption to my app?

One API call. H33 handles FHE encryption, ZK-STARK proof generation, Dilithium signing, and biometric matching — all in 35.25 microseconds. Integrate via REST API, Python/Node/Rust/Go SDKs, or a single script tag for BotShield. Get 1,000 free credits →

How does encrypted biometric matching work?

H33 performs the entire biometric match in encrypted space using BFV fully homomorphic encryption. Biometric data is encrypted on-device, transmitted encrypted, compared encrypted, and never exists in plaintext on any server. The result is a ZK-STARK proof revealing only match or no match.
