XRP May Be Less Exposed to Quantum Computing Threats Than Bitcoin

XRP Ledger (XRPL) validator analysis suggests that XRP may be less exposed to potential quantum computing threats compared to Bitcoin. Roughly 300,000 XRP accounts holding 2.4 billion XRP have never conducted a transaction, minimizing exposure to quantum attacks. In contrast, Bitcoin has around 6.7 million vulnerable addresses, equivalent to 32% of its total supply. XRP's account-based system and key rotation capabilities also contribute to its reduced risk exposure.

Recent analysis of the XRP Ledger (XRPL) suggests that XRP may be less exposed to potential quantum computing threats than Bitcoin, according to validator assessments. Approximately 300,000 XRP accounts, holding 2.4 billion XRP, have never sent transactions, meaning their public keys remain unexposed and quantum-safe by default according to validator assessments. This is attributed to the design of the XRP Ledger, which allows for key rotation without the need to move funds, offering an additional layer of security as explained by analysts.

In contrast, Bitcoin faces a more significant risk due to its transaction structure. A substantial portion of early Bitcoin was mined using the Pay-to-Public-Key (P2PK) format, which exposes public keys directly in the blockchain. This includes dormant accounts such as Satoshi Nakamoto's 1 million BTC, which have never been moved. Estimates suggest that between 2.3 million and 7.8 million BTC—representing 11% to 37% of the circulating supply—are potentially vulnerable to quantum attacks.

XRP's account-based model allows users to rotate signing keys without altering the account itself, reducing the risk of exposure during transactions according to MEXC analysis. Additionally, the XRP Ledger supports escrow and time-lock features, which provide further protection by limiting access to funds under specific conditions as reported by CoinDesk. These mechanisms are not natively available in Bitcoin, which lacks a built-in key rotation feature and requires users to move funds to new addresses to mitigate quantum risk—a process that temporarily exposes the old public key according to Cryptopolitan.

While quantum computing remains a theoretical threat, the structural differences between XRP and Bitcoin highlight varying levels of preparedness. XRP's design appears to offer a more resilient framework against potential quantum vulnerabilities, particularly for accounts that remain inactive or adopt proactive security measures.
