XRP Ledger: how the network is preparing for the quantum threat

The XRP Ledger Foundation has proposed a mechanism letting users rotate their account keys without moving their XRP, part of preparations against future quantum attacks. Ripple is targeting a transition by 2028, while Thomas Hussenet of XRPL Commons flagged the core challenge: migrating existing accounts without endangering funds or disrupting the network. The proposal matters because quantum computing could eventually break the cryptographic keys securing wallets, and XRPL's account model makes retrofitting harder than on chains designed with key rotation in mind. Watch for how the key-rotation design handles dormant and large accounts, and whether Ripple's 2028 timeline holds.
