The rise of quantum computing has sparked concerns about the potential vulnerability of legacy blockchains. However, experts believe that XRP's architecture makes it better equipped to withstand quantum attacks compared to Bitcoin.
This is due to XRP's account-based system, which allows for key rotation without requiring a new address, and its escrow feature, which provides an additional layer of protection. A recent audit of the XRP Ledger found that around 300,000 accounts holding 2.4 billion XRP have never sent any funds and are therefore quantum-safe by default.
In contrast, Bitcoin's blockchain lacks a key rotation feature, leaving holders more vulnerable to potential quantum attacks. Approximately 6.9 million BTC, or nearly 35% of Bitcoin's circulating supply, are vulnerable to quantum attacks, compared to just 0.03% of XRP's supply. While the threat is still largely theoretical, it highlights the relative structural vulnerability of Bitcoin holders.
