The rise of quantum computing has sparked concerns about the potential risks to legacy blockchains. For XRP holders, experts suggest that the token's architecture may offer better protection against quantum threats 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 security. In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to quantum attacks. While the threat is still largely theoretical, experts note that XRP's exposure is significantly lower, with only 0.03% of its circulating supply at risk, compared to Bitcoin's 35%. However, it's worth noting that Bitcoin developers are already working on proposals to develop quantum resistance.
