The rise of quantum computing has sparked concerns about the security of legacy blockchains, with Google warning that a powerful enough machine could compromise them. For XRP holders, the situation is more nuanced. Experts suggest that XRP's architecture provides better protection against quantum attacks than Bitcoin's. This is due in part to the XRP Ledger's features, such as key rotation, which allows users to change their signing key without moving funds, and escrow, which locks funds for a specified period.
A recent audit found that around 300,000 XRP accounts, holding 2.4 billion XRP, have never sent funds and are therefore quantum-safe. In contrast, Bitcoin's blockchain is more vulnerable, with an estimated 6.9 million BTC at risk, equivalent to nearly 35% of its circulating supply.
The lack of a key rotation feature in Bitcoin leaves holders with limited options to protect their funds, making XRP's design more resilient to quantum threats.
