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 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 protection. 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 point out that XRP's design and features make it less exposed to quantum risks, with only 0.03% of its circulating supply potentially at risk, compared to nearly 35% of Bitcoin's supply.
