The rise of quantum computing has sparked concerns about the security of legacy blockchains, with Google warning that a powerful enough machine could potentially exploit them. For XRP holders, experts offer a more nuanced assessment, suggesting that XRP's architecture provides better protection against quantum threats than Bitcoin's. This is due in part to the XRP Ledger's account-based system, which allows for key rotation without requiring a change of address.
A recent audit found that around 300,000 XRP accounts, holding 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 exploring proposals to develop quantum resistance, the current situation suggests that XRP may be more secure in the face of quantum computing threats.
