Ripple Researchers Propose Privacy-Preserving Transfers for XRPL Multi-Purpose Tokens
Ripple researchers proposed Confidential MPTs to add transaction privacy to the XRP Ledger for institutional use cases.Summary
The Ripple research team published a paper detailing Confidential Transfers for Multi-Purpose Tokens (Confidential MPTs), a proposal to introduce transaction privacy to the XRP Ledger (XRPL). This feature is intended to support institutional and regulated use cases by allowing issuer controls like freezing and clawbacks. Confidential MPTs are a cryptographic extension of the XLS-33 token standard, replacing plaintext balances with EC-ElGamal ciphertexts and using zero-knowledge proofs to verify transfer correctness without exposing data to validators, though sender/receiver identities remain visible. The abstract notes this provides cryptographic auditability via a selective-disclosure model compatible with existing audit methods. This development aligns with a recent US Treasury acknowledgment that lawful users seek privacy on public blockchains.
