The rise of quantum computing has sparked concerns about the potential vulnerability of legacy blockchains. However, experts suggest that XRP's architecture may be better equipped to withstand quantum attacks than Bitcoin's. This is due in part to the XRP Ledger's account-based system, which allows for signing key rotation, enabling users to change their account keys without moving funds.
Additionally, features like escrow with time locks provide an extra layer of protection. In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to quantum threats. While both cryptocurrencies have their vulnerabilities, XRP's exposure is significantly lower, with only 0.03% of its circulating supply at risk, compared to Bitcoin's 35%.
