XRP Ledger Shows Low Quantum Vulnerability

A recent on-chain analysis of the XRP Ledger has revealed that the cryptocurrency faces limited vulnerability to potential future quantum computing attacks, with the majority of its supply protected by design features that keep public keys hidden until transactions occur.

The analysis, conducted by XRPL validator Vet and shared earlier this week, examined over 7.7 million accounts on the network. It found that approximately 300,000 accounts, holding a combined 2.4 billion XRP, have never initiated an outgoing transaction. These accounts remain quantum-resistant because their public keys have not been exposed on the blockchain, preventing attackers from deriving private keys through algorithms like Shor's, which quantum computers could theoretically exploit. In contrast, only two dormant accounts inactive for more than five years have exposed public keys and significant balances, totaling about 21 million XRP. This represents just 0.03 percent of the circulating supply, highlighting the rarity of high-risk, inactive large holdings on the ledger.

Experts attribute XRP's relative resilience to the ledger's account-based structure, which differs from Bitcoin's UTXO model. Unlike...
