Ripple says quantum computing threat no longer a fantasy, unveils XRP Ledger roadmap

Ripple said it will transition the XRP Ledger to a quantum-computing response system by 2028. It said assets are not in immediate danger, but the quantum threat has moved from theoretical to a realistic level, making timing for preparation important. Ripple warned that “harvest now, decrypt later” poses higher risk. It said XRP Ledger has an advantage because it supports protocol-level key replacement, unlike Ethereum.
