The emergence of quantum computing has sparked concerns about the security of legacy blockchains, with experts suggesting that XRP's architecture may be better equipped to withstand potential threats than Bitcoin's. XRP operates on the XRP Ledger, a decentralized, open-source blockchain that facilitates cross-border transactions through Ripple, a fintech firm. A key difference lies in the exposure of public keys, which can be reverse-engineered by a sufficiently powerful quantum computer, potentially draining funds. However, XRP's design and features such as key rotation and escrow provide additional layers of protection.
A recent audit found that around 300,000 XRP accounts, holding 2.4 billion XRP, have never sent funds and are therefore quantum-safe by default. In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to quantum attacks, with an estimated 6.9 million BTC at risk.
