The rise of quantum computing has sparked concerns about the potential vulnerability of cryptocurrencies to quantum attacks. However, experts suggest that XRP's architecture may be better equipped to withstand such threats than Bitcoin's. This is due in part to XRP's account-based system, which allows for the rotation of signing keys without requiring a transaction, thereby reducing exposure to quantum attacks.
Additionally, XRP's escrow feature, which locks funds for a specified period, provides an extra layer of protection. In contrast, Bitcoin's lack of a key rotation feature and its use of a format called P2PK, which exposes public keys directly in transaction outputs, may make it more vulnerable to quantum attacks. According to estimates, around 35% of Bitcoin's circulating supply may be at risk, compared to just 0.03% of XRP's.
While the threat is still largely theoretical, experts emphasize the importance of developing quantum-resistant algorithms and features to protect against potential attacks.
