XRP Ledger has integrated biometric identity into its decentralized infrastructure through a system called Genomic Hash Mesh of DNA Protocol. This system protects human DNA as an anchor of verifiable identity on the blockchain, marking the first time genomic data has been cryptographically verified and recorded in real-time on a blockchain.
Genomic Hash Mesh uses zk differential compression to convert genomic data into a verifiable format, and nodes confirm these signatures with hashes through Merkle-linked certification, providing a reliable identity without centralized databases.
This development introduces a novel intersection between blockchain and biomedical data, with XRP driving what DNA Protocol refers to as a new frontier: BioFi.
