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 proposal. The move matters because quantum computing threatens the elliptic-curve cryptography securing most blockchain accounts, and XRPL is among the first major networks to map out a concrete migration timeline. What to watch next is how the design is implemented across the ledger’s validator ecosystem and whether other chains follow with comparable deadlines.
