The XRP Ledger Foundation has published a design proposal to introduce quantum-resistant accounts to the network, aiming to protect users against future quantum computing threats without imposing additional base transaction fees.[1][3]

Under the proposed architecture, account holders would be able to attach a National Institute of Standards and Technology (NIST)-approved ML-DSA-44 signing key to their account and disable their existing key. According to BSCN, the capability is intended to safeguard accounts whose public keys have already been exposed on-chain.[1]

The design is part of a broader roadmap charting a complete network transition to quantum protection by 2028, with an initial migration study scheduled for the first half of 2027. Crypto outlets also noted that Ripple has set a target of achieving full quantum protection across the ledger by 2028.[1][2][3][4]

Key facts

  • The XRP Ledger Foundation outlined a design enabling account holders to add a quantum-resistant key and deactivate their old key.
  • The proposed account upgrade incorporates a NIST-approved ML-DSA-44 signing key.
  • The upgrade is designed to protect accounts with already exposed public keys without raising base transaction fees.
  • A migration study for the transition is scheduled for the first half of 2027.
  • The roadmap targets a full transition to quantum-resistant accounts by 2028, a timeline also targeted by Ripple.
