XRP quantum-vulnerability at 0.03% vs Bitcoin 32% amid rising quantum threat

A validator on the XRP Ledger reports XRP quantum exposure is limited: only ~0.03% of XRP supply is considered quantum-vulnerable. The figure is linked to many XRP accounts never revealing public keys on-chain. On XRP, around 300,000 accounts holding roughly 2.4 billion XRP have never transacted, so they currently remain shielded under today’s quantum threat models. Separately, just two XRP wallets with about 21 million XRP have been inactive for over five years while still showing public keys on-chain—also keeping the overall vulnerable share very small. The article contrasts this with Bitcoin. Google-linked analysis estimates ~6.7 million BTC—about 32% of total BTC supply—resides in addresses exposed to potential quantum decryption, because their public keys have appeared on-chain. It also mentions ~1 million BTC attributed to Satoshi Nakamoto, which Charlie Lee warns could be even less protected if quantum advances. While no current quantum computer can break existing blockchain encryption, the long-term solution is upgrading to quantum-resistant cryptography. The XRP Ledger is also highlighted for allowing signing key rotation without changing the account address, which is designed to reduce exposure. Key takeaway for traders: today’s quantum narrative favors XRP’s relative risk profile versus Bitcoin (0.03% vs 32%), but market impact will depend on future quantum-resistant adoption and any subsequent security research updates.
