Solana-Privacy proved compliance to the regulator and privacy to the user on Solana devnet. Polygon-Privacy brings the same H33-74 attestation to EVM-native rails. Bitcoin-Privacy makes the proof permanent — one 32-byte commitment anchored via Taproot script-path (production) or OP_RETURN (alternative), on the deepest proof-of-work chain in existence.
Schedule Demo See Solana-Privacy (Live)Bitcoin privacy is the expression of the H33 Privacy Layer on Bitcoin. It protects the privacy of your evidence, identity, and chain interaction while anchoring a portable, independently verifiable attestation to Bitcoin. The privacy mechanism is a combination of zero-knowledge proof (ZK — STARK, no reveal), selective disclosure, and data minimization; the portable evidence itself is produced by H33-74 (the 74-byte post-quantum attestation), and the verdict is rendered by Verification. Bitcoin is the reference environment the evidence anchors to — one 32-byte commitment via Taproot script-path or OP_RETURN — never the producer of the proof.
Why this exists: Bitcoin is the deepest proof-of-work chain in existence, so a commitment anchored there is as permanent as evidence gets — but the chain itself exposes the entire UTXO set and has no privacy, no smart-contract verifier, and no post-quantum signatures. The Privacy Layer supplies privacy and portable post-quantum evidence, while Bitcoin supplies only permanence — a hash that outlives ECDSA.
This widget streams Bitcoin mainnet block heights, block hashes, and recommended mempool fees in real time via WebSocket — the same Bitcoin RPC path that will publish H33-74 attestations to Bitcoin OP_RETURN once the public anchor endpoint is provisioned. The Solana-Privacy demo at h33.ai/solana-privacy/#try-it generates the full STARK + PQ-signed proof flow today on Solana devnet.
When the public Bitcoin anchor endpoint ships, the try-it surface will:
Tornado Cash proved privacy without compliance becomes a regulatory dead end.
Polygon-Privacy proves privacy to the user while proving compliance to the regulator — post-quantum signed, replayable offline, and portable across Bitcoin, Solana, and Polygon zkEVM.
That’s the operational primitive institutional AI and RWA systems are missing.
Every H33-74 receipt is reconstructible from its commitment. Inspect lineage. Inspect proof. Inspect DAG. Verify signatures. On Bitcoin, the commitment lives forever in the deepest PoW chain.
Compliance to the regulator. Privacy to the user. Post-quantum attestation that outlives ECDSA — anchored to the deepest proof-of-work chain in existence.

No. Bitcoin privacy is an expression of the Privacy Layer — it protects evidence, identity, and chain interaction using ZK, selective disclosure, and minimization. Encrypted computation over data that never decrypts is a separate mechanism (FHE), covered at /fhe/. The two share the word “privacy” but not the mechanism.
No. Bitcoin has no smart contracts and no on-chain verifier. The proof is produced by H33-74 and its verdict is rendered off-chain by Verification. Bitcoin is the reference environment the 32-byte commitment anchors to — it stores permanence, not logic.
