This is a live attestation. Every hash, signature, and commitment you see below was generated in real-time by the H33 cryptographic engine. Nothing is mocked.
🔐
Privacy is the load-bearing feature
The asset is encrypted with BFV homomorphic encryption and never decrypted at any subsequent step. The compliance check runs on the encrypted data. A STARK zero-knowledge proof is then generated showing the compliance check ran correctly — without revealing the inputs, the encryption keys, or the compliance predicates. The bundle is signed by three independent post-quantum signature families and committed to Avalanche. The chain sees only the proof that compliance passed.
A simulated $25M tokenized real-world asset (RWA) — a U.S. Treasury obligation issued on an Avalanche subnet — goes through the full H33-74 privacy & attestation pipeline. The asset is encrypted with BFV homomorphic encryption (data is never visible in plaintext), a TFHE compliance check runs on the encrypted data, and a STARK zero-knowledge proof is generated to prove the compliance check ran correctly — without revealing the asset, the keys, or the predicates.
The result is signed by three independent post-quantum signature families and the 32-byte commitment is anchored to Avalanche C-Chain. Anyone with the bundle and the STARK proof can verify everything independently — without contacting H33 and without decrypting anything.
STEP 1 / 8WAITING
Create Tokenized RWA
Simulated $25M U.S. Treasury obligation issued on an Avalanche subnet
What's happening: A tokenized asset is created with an ISIN identifier, face value, subnet ID, counterparty, and 10-year maturity. This is the raw institutional instrument that will be made portable and compliance-verifiable without ever exposing its terms to the public chain.
STEP 2 / 8WAITING
Encrypt with FHE
Asset data encrypted using BFV Fully Homomorphic Encryption
What's happening: Every field of the asset (face value, counterparty, maturity, subnet, jurisdiction) is encrypted using lattice-based homomorphic encryption. The data is never decrypted again for the remainder of the attestation. No subsequent step — not compliance, not the STARK proof, not signing, not anchoring — ever sees plaintext.
STEP 3 / 8WAITING
Encrypted Compliance Check
TFHE threshold check on encrypted data: "Is the asset compliant with subnet policy?"
What's happening: Using TFHE (optimized for encrypted comparisons), the system verifies subnet policy: counterparty is on the whitelist, face value is within the subnet's permitted range, jurisdiction is allowed. The compliance check runs entirely on encrypted bits. The verifier never sees the asset; the asset never leaves the encrypted envelope.
STEP 4 / 8WAITING
STARK Proof of Encrypted Compliance ZK
Zero-knowledge proof that Step 3's TFHE compliance evaluation ran correctly — without revealing the inputs or keys
What's happening: The TFHE compliance circuit is arithmetized over a STARK-friendly field and a transparent ZK proof is generated showing that (a) the encrypted inputs were valid ciphertexts under the published parameters, (b) the compliance predicate was applied correctly to those ciphertexts, and (c) the COMPLIANT verdict is the honest output. Why this matters: without the STARK, a verifier would have to trust H33 that compliance was evaluated correctly. With it, the verifier checks the proof in milliseconds and gets cryptographic certainty — while the asset, the keys, and the predicate weights stay private. Transparent setup (no trusted ceremony), post-quantum secure, hash-based.
STEP 5 / 8WAITING
Asset Fingerprint
SHA3-256 hash of the encrypted asset bundle + compliance result + STARK proof
What's happening: A cryptographic fingerprint is computed over the encrypted asset, the compliance verdict, and the STARK proof. This fingerprint uniquely identifies this specific attestation. It binds the encrypted data, the policy that was checked, the zero-knowledge proof of correct execution, and the outcome — all without revealing any of them.
STEP 6 / 8WAITING
Mint H33-74 Primitive
58-byte attestation primitive — the permanent cryptographic record
What's happening: The fingerprint is embedded into a 58-byte H33-74 primitive. This is the atomic unit of trustless verification in the H33 system. It contains a version byte, a computation-type byte (0x41 for SubnetAssetAttestation), the 32-byte SHA3-256 commitment, an 8-byte nanosecond timestamp, and 16 bytes of binding metadata.
STEP 7 / 8WAITING
Three-Family Post-Quantum Signing
ML-DSA-65 + FALCON-512 + SLH-DSA-SHA2-128f — three independent mathematical bets
What's happening: The H33-74 primitive is signed by three different post-quantum signature algorithms, each based on a different mathematical hardness assumption. To forge this signature, an attacker would need to break lattice problems, NTRU lattice problems, AND stateless hash functions simultaneously. No known or theoretical quantum computer can do this.
STEP 8 / 8WAITING
Avalanche C-Chain Anchor FUJI TESTNET
32-byte commitment permanently anchored to Avalanche via self-send tx with calldata
What's happening: The first 32 bytes of the H33-74 primitive (the SHA3-256 commitment) are written to Avalanche C-Chain as the calldata of a self-send transaction. Once confirmed, the bundle is permanently anchored. Verification is trustless: anyone with the bundle, the STARK proof, and the verifier binary can confirm the anchor matches, the compliance ran correctly, and the signatures are valid — without contacting H33.
Mainnet status: Fuji testnet anchoring runs today. Mainnet anchoring is gated behind a custody decision record (no H33-held mainnet signing key) — the crate never holds private keys, the customer signs offline, H33 broadcasts the signed tx, the verifier confirms inclusion.
Verification
Every value below was generated by the H33 cryptographic engine in your browser. You can independently verify the H33-74 structure, the STARK proof, the PQ signatures, and the on-chain anchor without contacting H33.
Decrypt the Asset
The asset metadata below is AES-256-GCM encrypted in your browser. Paste the decryption key to reveal it. Wrong key → no data. This is the same privacy property the on-chain anchor preserves: the chain doesn't decrypt this either — and the STARK proof confirms compliance ran correctly without anyone decrypting it.

YOUR DECRYPTION KEY (256-bit, hex):
HOW THIS WORKS IN PRODUCTION
This demo uses AES-256-GCM in your browser (via Web Crypto) so you can hold the key and decrypt the asset yourself. In production, H33 uses BFV Fully Homomorphic Encryption: the asset is never decrypted at any point — not for compliance, not for STARK proving, not for signing, not for anchoring. Only the asset owner ever holds the FHE secret key.
The STARK proof is what makes the privacy verifiable. Without it, a counterparty would have to trust H33 that the compliance gate ran correctly on the encrypted inputs. With it, anyone holding the bundle can run a small verifier that takes milliseconds and returns a cryptographic yes/no — without ever seeing the inputs, the keys, or the predicate. Transparent setup (no trusted ceremony), post-quantum secure, hash-based.
The Avalanche anchor proves that the encrypted data was processed correctly (FHE + STARK-verified compliance) without ever decrypting it. The chain confirms the bundle existed at the anchored block height, that the commitment matches, and that no other party — including H33 — can have substituted it.
Three independent post-quantum signature families (ML-DSA, FALCON, SLH-DSA) sign the attestation. To forge it, an attacker would need to simultaneously break lattice problems, NTRU problems, AND stateless hash functions.
