Building blocks for data & oracles privacy

Private ISO 20022 Messaging & Settlement

Coordinate private ERC-20 settlements between banks using ISO 20022 as the instruction layer. The ISO message binds to the on-chain cash leg, while the cash leg itself settles privately via a shielded mechanism (privacy L2, shielded pool, or confidential token) with regulator-only visibility.

Low-cost L2 + Off-chain Encrypted Audit Log

Run settlement on a low-cost L2, publish only commitments and hashes on chain, and keep the full transaction facts in an append-only encrypted log off chain. Integrity is anchored by periodic Merkle roots submitted on chain. Regulators and auditors receive scoped decryption keys or predicate proofs. Delivery-versus-payment is expressed through an atomic settlement standard.

Who builds data & oracles privacy tooling

Chainlink ACE

Modular compliance layer built on the Chainlink Runtime Environment (CRE) to define, execute, and enforce identity- and policy-based controls for digital assets across public and private chains. Core onchain components (CCID, CCT Compliance Extension) pair with CRE services (Policy/Identity/Monitoring managers). Offchain policy execution returns signed approvals; onchain enforcement is required. PII/NPI remains offchain. It enables private transactions, with one of the main target use cases being CBDCs management.
