The Future of AML Lies in Cryptographic Proofs, Not Surveillance

Legacy KYC/AML is a cost center with diminishing returns. It's a privacy-invasive dragnet that fails to catch sophisticated actors, creating friction for billions of legitimate users.\n- Cost: ~$50B+ spent annually on compliance, with ~2% of illicit funds seized.\n- Failure: Tornado Cash sanctions proved the futility of address-level blacklists.\n- Friction: Onboarding times of days, blocking global financial access.

Users prove compliance criteria without revealing underlying data. A wallet can prove it's from a non-sanctioned jurisdiction or passed a KYC check, with the credential verified on-chain.\n- Privacy: Selective disclosure via ZK-SNARKs. Prove age >18 without showing DOB.\n- Portability: Sismo ZK Badges are reusable across dApps, eliminating redundant checks.\n- Composability: Credentials become programmable inputs for DeFi and DAO governance.

New architectures like Anoma and UniswapX separate transaction execution from sensitive details. AML logic shifts from surveilling all data to verifying cryptographic proofs of intent.\n- Intent-Based: User declares goal ("swap X for Y"), solver handles compliance. See Across, CowSwap.\n- Programmable: Compliance rules (e.g., "only accredited investors") are enforced by zk-Circuits, not middlemen.\n- Scale: Enables mass adoption by embedding compliance into the protocol layer, invisible to compliant users.

Today's AML relies on mass data collection (KYC, transaction monitoring) that is ineffective, expensive, and invasive. It creates a ~$50B+ annual compliance burden and leaks sensitive user data in centralized honeypots.

• High False Positives: >95% of flagged transactions are legitimate, wasting analyst time.
• Privacy Trade-off: Users surrender financial sovereignty for minimal security gain.
• Centralized Risk: Data breaches at exchanges and VASPs compromise millions.

Cryptographic proofs allow users to demonstrate compliance without revealing underlying data. A user can prove their funds are not from a sanctioned source or that they passed KYC, with the proof itself being the credential.

• Selective Disclosure: Prove specific AML predicates (e.g., "funds are from a non-sanctioned jurisdiction") and nothing more.
• Interoperable Credentials: A zk-proof from one protocol can be reused across DeFi, reducing repetitive KYC.
• Audit Trail: Regulators can cryptographically verify the proof's validity without seeing personal data.

A privacy-focused L2 that pioneered private DeFi. Its architecture demonstrates how shielded pools can integrate compliance via viewing keys and proof-based attestations, setting the template for private-yet-auditable finance.

• Shielded Pools: Assets are private by default, with compliance built into the protocol layer.
• Regulatory Viewing Keys: Users can grant selective audit access to authorities via cryptographic keys.
• On-Chain Attestations: Proofs of legitimacy can be generated from within the private system.

Every exchange, bridge, and dApp runs its own OFAC list checks and transaction monitoring, leading to redundant work, inconsistent results, and fragmented risk models. This creates gaps criminals exploit and slows down legitimate cross-chain activity.

• Chain Hopping: Illicit funds move through unscreened bridges and nascent chains.
• Compliance Latency: Screening lags behind real-time blockchain activity, creating windows of vulnerability.
• No Shared Reputation: A wallet blacklisted on one chain remains active on another.

A neutral, decentralized network (like a zk-rollup or co-processor) that maintains a constantly updated, verifiable ledger of risk attestations. Protocols query it with a cryptographic proof of a user's history, receiving a proof of risk score in return.

• Universal Source of Truth: A single, cryptographically verifiable set of sanctions lists and risk indicators.
• Real-Time Proofs: Protocols can request and verify risk assessments in ~500ms.
• Privacy-Preserving: The attestation ledger doesn't see the query details, only validates the proof logic.

Implements the Privacy Pools concept, which uses zero-knowledge proofs to allow users to dissociate from illicit funds within a shared pool. Users generate a proof of membership in a legitimate subset, providing a cryptographic basis for compliant privacy.

• Association Sets: Users prove their funds originate from a set of addresses not linked to known illicit activity.
• Protocol-Level Compliance: Compliance is a property of the cryptographic proof, not external surveillance.
• Evolving Standards: Serves as a live R&D platform for regulatory-compatible privacy tech.

Legacy regulators are structurally incentivized to prefer the flawed but familiar surveillance model. The FATF Travel Rule is a $10B+ compliance industry built on data sharing, not zero-knowledge proofs.

• Key Risk: Regulators may mandate backdoors, treating privacy-enhancing tech (PETs) like Tornado Cash as non-compliant by default.
• Key Risk: Jurisdictional fragmentation. A proof accepted in the EU may be rejected by FinCEN, forcing protocols to run multiple compliance circuits.

Cryptographic AML relies on trusted oracles (e.g., Chainlink, EigenLayer AVSs) to attest to real-world identity credentials. This creates centralized choke points.

• Key Risk: Oracle collusion or compromise becomes a single point of failure for the entire compliance layer.
• Key Risk: Cost and latency. Fetching and verifying an attestation adds ~500ms-2s and $0.10-$1.00 per transaction, killing UX for micro-transactions.

Systems like Aztec, Nocturne, or zk-proofs of solvency must balance anonymity with provable compliance. This is a cryptographic and game theory nightmare.

• Key Risk: Identity leakage. If a user's proof is linked across sessions, you rebuild the surveillance graph.
• Key Risk: Regulatory arbitrage. Bad actors will flock to jurisdictions with the weakest proof requirements, creating 'AML havens' that draw enforcement scrutiny to the entire ecosystem.

Every chain or L2 (e.g., zkSync, Arbitrum, Solana) may implement its own proof standard. A user compliant on Ethereum may be unknown on Cosmos.

• Key Risk: Liquidity fragmentation. Compliance becomes a barrier to cross-chain intents via LayerZero or Axelar.
• Key Risk: Developer overhead. Teams must integrate with multiple, competing attestation networks, increasing integration time by 3-6 months.
