XRP Shows Lower Quantum Exposure Than Bitcoin, Experts Say

• XRP shows minimal quantum exposure, with only 0.03% of supply in wallets with revealed public keys.
• Bitcoin faces higher risk, with up to 37% of supply potentially exposed due to address reuse and structure.
• XRP’s key rotation and account design enhance security, though quantum threats remain theoretical today.

Experts point to XRP’s lower exposure to quantum threat compared to Bitcoin. According to XRPL validator Vet, XRP shows minimal vulnerability due to wallet behavior and design. The findings come amid rising concerns following Google’s recent quantum-focused research.

According to Vet, only about 21 million XRP sits in wallets with exposed public keys. This equals roughly 0.03% of the total circulating supply. Notably, these funds belong to two long-dormant whale accounts.

However, most XRP wallets have never revealed their public keys through transactions. Around 300,000 accounts holding 2.4 billion XRP remain unexposed. As a result, these accounts stay “quantum-safe by default,” according to the analysis.

This difference links directly to how XRP handles accounts. Unlike Bitcoin, XRP does not require public key exposure before spending. Consequently, fewer wallets face potential future risks.

In contrast, Bitcoin’s structure exposes more public keys during transactions. Early P2PK outputs and reused addresses contribute to this issue. Estimates suggest between 11% and 37% of Bitcoin’s supply could be vulnerable.

This includes coins from early network activity that cannot rotate keys. As a result, these holdings remain exposed if quantum capabilities advance. However, no current quantum systems pose a real threat today.

Still, the comparison highlights structural differences. XRP allows key rotation without moving funds, while Bitcoin lacks this native feature. This distinction shapes the current risk assessment.

Beyond exposure levels, XRP includes additional security mechanisms. Key rotation allows users to update credentials without transferring assets. Meanwhile, escrow and time-lock features can restrict access conditions.

These tools provide flexibility in managing potential risks. According to Vet, users can strengthen security without complex steps. This becomes relevant as discussions around post-quantum solutions continue.However, experts stress that current risks remain theoretical. Vet noted that no known quantum computer can break blockchain cryptography today. As a result, both networks continue operating without immediate threat concerns.
