The recent advancements in quantum computing have sparked concerns about the potential risks to blockchain security. Experts suggest that XRP's architecture may be better equipped to handle these threats than Bitcoin's. The XRP Ledger, an open-source and decentralized blockchain, facilitates cross-border transactions using the XRP digital token.
A key difference between XRP and Bitcoin lies in their exposure to quantum attacks. A quantum computer powerful enough to run Shor's algorithm could potentially reverse-engineer a private key from a public key, allowing an attacker to drain funds from a wallet. Typically, a public key is exposed when a transaction is sent, but XRP's key rotation feature allows users to change their signing key without moving funds, making their accounts more secure. Experts Vet and Mayukha Vadari pointed out that XRP's account-based system and features like escrow with time locks provide additional protection against quantum risks.
In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to quantum attacks. Approximately 6.9 million BTC, nearly 35% of Bitcoin's circulating supply, may be at risk due to exposed public keys, whereas only 0.03% of XRP's circulating supply is potentially vulnerable.
