[CoinDesk] XRP Ledger maps out quantum-proof accounts, with no extra fees for users

The XRP Ledger Foundation has outlined a design allowing account holders to add a quantum-resistant key and disable their existing one, putting the network on a path toward a full post-quantum transition by 2028. The upgrade would come at no extra cost to users, according to the plan. The move matters because quantum computing poses a long-term threat to the elliptic-curve cryptography securing most blockchain accounts, and XRPL is among the first major networks to publish a concrete migration timeline. What to watch next is how the design moves from roadmap to amendment, and whether other layer-1 networks follow with their own quantum-proofing schedules.
