Ripple is preparing the XRP Ledger for the potential arrival of quantum computers capable of threatening existing cryptographic systems, according to CoinDesk. The effort comes as concern over “Q-Day” grows across the crypto industry. CoinDesk reported that an Anthropic model reduced the work required to break a leading post-quantum signature candidate by a factor of 67 million last month. The development has added urgency to discussions about how blockchain networks could transition to cryptography designed to withstand quantum attacks. Bitcoin and Ethereum published their own migration plans this week, signaling that quantum resistance is becoming a broader infrastructure issue for major digital-asset networks. The reports are relevant to XRP, as well as other cryptocurrencies whose security depends on cryptographic signatures. No timetable or specific technical details for Ripple’s XRP Ledger preparations were provided in the supplied information.
