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.
