Compliance is built in, not bolted on
How a self-custodial shielded pool protects users without becoming a haven for illicit contagion: screening at the edge, scoped viewing keys, and zero-knowledge attestations on Robinhood Chain.
Clean money in, clean money out.
Unlike legacy mixers that pool taint and freeze capital, MARGINALIA separates clean actors from sanctioned clusters before commitments enter the tree.
Edge Compliance Screening
Sanctions, OFAC lists, and chain intelligence checks happen strictly at the deposit boundary via the Magistrate ASP register. Dirty funds are rejected at the door.
Identity Separation
Your real-world identity stays with the licensed ramp or broker. MARGINALIA never sees, receives, or stores KYC records or documents.
Decorrelated Withdrawals
Zero-knowledge proofs break transaction graphs without breaking provenance. Clean origin can be mathematically verified at withdrawal without linking addresses.
Show exactly what’s needed. Never more.
When an auditor, tax agency, or lender requests transaction provenance, provide an authenticated cryptographic letter of disclosure encrypted directly to their public key.
Disclose an individual note or a specific tax period without revealing subsequent pool transactions.
Viewing permissions expire automatically after the compliance audit window concludes.
Deposit origins and amounts are encrypted using ECDH X25519 and verified with HMAC authentication.
Produces standard cryptographic JSON packages compatible with standard enterprise audit software.

Who you can prove things to
Compare disclosure ergonomics between a conventional public wallet and MARGINALIA’s zero-knowledge protocol.
| Counterparty | Public Wallet | MARGINALIA / Noirpay Standard |
|---|---|---|
| Accountant | Full history disclosed forever; leaks all balances | Scoped viewing key for specific tax year only |
| Auditor / Regulator | Exposes upstream & downstream client relationships | Cryptographic Letter of Disclosure with X25519 cipher |
| Lender | Reveals liquidation thresholds & portfolio sizing | Zero-Knowledge Proof of Funds (Balance > threshold) |
| Banking Partner / Card Issuer | Public transaction receipts tied directly to KYC | Screened edge settlement with zero on-chain tracing |
| Business Client | Client sees your corporate treasury & supplier payouts | One-time stealth addresses; balance stays shielded |
What MARGINALIA never sees
Your Balances & Positions
Commitments are Poseidon hashes encrypted with your private secret. Neither relayer, sequencer, nor Magistrate node can inspect how much you hold.
Your Identity Records
We store zero personal information, IP addresses, or government identification documents. All proofs are computed client-side in WebAssembly.
No Master Backdoors
There is no administrative master key, god-mode freeze, or forced decryption circuit. Once an encrypted note is inscribed, only the holder of the private key can spend it.
