XRP is reportedly better positioned than Bitcoin to withstand potential quantum computing attacks, according to recent on-chain analysis. Researcher Vet highlighted that approximately 300,000 XRP accounts, holding a total of 2.4 billion tokens, have never made an outgoing transaction, keeping their public keys hidden and resistant to quantum threats. In contrast, Bitcoin's older address types and dormant "whale" holdings, such as those linked to Satoshi Nakamoto, present a larger attack surface. The XRP Ledger's design, which conceals public keys until transactions are signed, offers a layer of protection against quantum-based attacks. Additionally, the ledger supports signing key rotation, allowing users to update credentials without changing accounts. Ripple engineer Mayukha Vadari noted that XRP's escrow mechanisms provide further security, as funds locked in escrow cannot be accessed prematurely, regardless of computing power. Concerns about quantum computing's impact on crypto security have intensified following a Google research paper suggesting that advanced machines could compromise major crypto wallets. Efforts to mitigate these risks include deploying post-quantum signature schemes on Bitcoin sidechains, offering enhanced protection without altering the main protocol.
