ISO and IEC standards

The regime itself mandates, pilots or funds privacy-preserving technology.

What ISO and IEC standards actually says

Set this against the financial standard-setters and the contrast is sharp. In February 2026 ISO and IEC published guidelines on privacy preservation based on zero-knowledge proofs, meaning there is now an international standard for deploying the primitive that the anti-money-laundering bodies do not mention at all. FATF's July 2026 report on information sharing identifies data protection law as the main obstacle to cooperation and names no privacy-enhancing technology anywhere. ISO's blockchain committee has treated privacy as an engineering problem since 2020, when its technical report on personally identifiable information in distributed ledgers addressed immutability against erasure directly. None of this binds anyone unless a regulator or contract adopts it, which so far none has.

What this means for confidential transactions

Bubble is built for exactly this shape of obligation: amounts and balances live on chain as ciphertexts, computation happens without decryption, and the only disclosure path is an on-chain access list through which an authorized party - an auditor, a supervisor, a counterparty - can request scoped decryption. That is confidentiality from the public, not from the regulator.
