The rise of quantum computing has sparked concerns about the potential threats it poses to blockchain security. Experts suggest that XRP's architecture may be better equipped to withstand these threats than Bitcoin's. XRP operates on the XRP Ledger, a decentralized, open-source blockchain that facilitates cross-border transactions.
A recent audit found that approximately 300,000 XRP accounts, holding around 2.4 billion XRP, have never sent funds and are therefore quantum-safe by default. In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to quantum attacks. While Bitcoin developers are working on proposals to develop quantum resistance, XRP's existing features may provide an added layer of security. The XRP Ledger's key rotation feature allows users to change their signing key without moving funds, and the escrow feature provides an additional layer of protection.
However, dormant accounts that have not rotated their keys remain vulnerable. Experts note that the quantum threat to Bitcoin appears more significant due to the sheer scale of vulnerable accounts, including Satoshi Nakamoto's 1 million BTC, which has never moved. Overall, while both XRP and Bitcoin face potential quantum threats, XRP's design and features may make it less exposed to these risks.
