The rise of quantum computing has sparked concerns about the security of legacy blockchains, with Google warning that a sufficiently powerful machine could compromise them. For XRP holders, experts suggest that the cryptocurrency's architecture provides better protection against quantum threats than Bitcoin's. This is due to the XRP Ledger's open-source, decentralized blockchain and features like key rotation, which allows users to change their signing key without moving funds.
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, with an estimated 6.9 million BTC at risk.
