XRP safer than Bitcoin from quantum threats, says analysis

An analysis suggests that XRP's structure is safer from quantum computing threats than Bitcoin's, CoinDesk reported. The vulnerability lies in the exposure of public keys during fund transfers, which could theoretically allow a quantum computer to derive the private key and steal assets. An estimated 2.3 million to 7.8 million Bitcoin, or 11% to 37% of the total circulating supply, are considered "quantum vulnerable" due to their public keys being directly exposed. Furthermore, securing these funds requires moving them to a new address, a process that briefly exposes the public key and creates an opportunity for a quantum attack. In contrast, only about 21 million XRP, or 0.03% of the circulating supply, have exposed public keys. The analysis also noted that the XRP Ledger (XRPL) allows an account's signing key to be replaced without moving the underlying funds, making it relatively more secure against this type of threat.
