The $XRP Ledger (XRPL) has reached an important milestone by recording its first zero-knowledge (ZK) proof transaction on the testnet.
The transaction was initiated by DNA Protocol, a blockchain-based platform that allows users to manage and control their biological identity on-chain. This development shows the $XRP Ledger’s capability to support privacy-focused transactions linked to DNA data.
Key Points
- The XRPL recorded its first ZK proof transaction on March 25, 2026, which anchored a verified proof from real genomic data onto the testnet.
- The transaction used a small 0.000001 $XRP transfer and stored only cryptographic proof data to ensure no sensitive information like DNA was exposed on-chain.
- The development could lead to privacy-focused use cases such as private KYC/AML checks, selective disclosure, and secure handling of medical and financial data.
- Ripple is also proposing a Confidential MPT protocol to introduce encrypted token balances and hidden transfer amounts.
Technical Details of the XRPL Transaction
DNA Protocol carried out the transaction on March 25, 2026, at 11:19 AM UTC, but later shared the update on March 28. Notably, the transaction anchored a ZK proof created from real genomic identity data collected from a certified lab in Zimbabwe, which the Proof Anchor interface marked with a Zimbabwe flag.
The system processed the transaction as a Payment type, using a very small transfer of 0.000001 $XRP to lock the proof on the ledger. It involved a sender and receiver address, considering its nature as a Payment.
The transaction also included several memos involving DNA Protocol, stored in formats like text/plain and bin/v2. These memos carried encoded cryptographic data, including commitments, proof elements, and validation markers such as nullifiers. However, the system kept all sensitive data, including DNA details, off-chain and only stored the proof itself.

All verifiable. All private.Currently operating on the #XRPL Testnet, with pilot programs underway across multiple countries leveraging DNA Protocol.

How DNA Protocol Executes Privacy-Preserving Verification
To carry out the process, DNA Protocol takes lab data off the blockchain and turns it into a ZK proof using its tools and cryptographic circuits. It then checks the proof before anchoring a commitment on XRPL. This ensures that the data remains private while still being confirmed and stored in a secure and permanent way.
With this method, institutions like banks, governments, and compliance systems can verify information without seeing the actual data. Users only need to prove that their data meets certain conditions instead of sharing details. This introduces a new way of handling identity in which proof replaces the need to expose personal information.
Potential Institutional Use Cases
This development could lead to multiple real-world uses on the XRPL. Specifically, it supports private KYC and AML checks, allows selective sharing of information, and helps manage sensitive data in areas like healthcare and finance. It can also support proof-of-reserves systems without revealing details about users or transactions.
DNA Protocol has already started pilot programs in different countries, including Zimbabwe and Nigeria. The testnet is actively processing lab data, showing that this system works in real situations and not just in theory.
Ripple’s Confidential MPT Initiative
Meanwhile, Ripple is working on its own privacy solution called Confidential Transfers for Multi-Purpose Tokens. This builds on the XLS-33 token standard, which went live on XRPL mainnet in October 2025, and adds features to hide balances and transfer amounts.
Researchers such as Murat Cenk, Aanchal Malhotra, and Joseph A. Akinyele, Ripple’s Head of Engineering, developed the proposal. They published it as IACR ePrint 2026/602 last week. Notably, their design uses encrypted balances and zero-knowledge proofs to confirm transactions without revealing sensitive details.
The system still keeps sender and receiver identities visible, but it hides balances and transfer values. It also works with existing token rules, supports controls like freezing or clawing back funds, and allows selective disclosure for audits.
Developers have tested an open-source version called mpt-crypto with XRPL validators, and results show it can work within network limits. However, this feature is still in draft form and needs approval from the XRPL community before it can go live.
