The XRP Ledger just made a big move on quantum safety.
Its foundation put a quantum-proof upgrade in the 2027 roadmap.
Owners will add a new quantum-resistant key and switch off the old one.
The full switch is planned by 2028.
š By the numbers:
3,732 bytes vs 105 for a normal payment | ~3.6KB extra per tx | $215Kā$255K set aside for audit
š $XRP now: ~$1.10 (+1.54% today)
š Why it matters:
Every $XRP payment ever made left its public key on-chain.
A strong enough quantum computer could crack those old keys one day.
This move gets ahead of that risk before it becomes real.
āļø What happens next:
The migration study lands in the first half of 2027.
Then dev work and audits run through late 2027 into 2028.
Validators still have to vote the change in.
š¬ Bulls say the ledger just got ahead of every major chain ā quantum-proof by 2028, free for users. Bears say real quantum attacks are still years off, and 3.6KB signatures bloat each payment 3.1Ć. Which side are you on?
