  "account": "Ripple has embarked on a multi-phase plan to prepare the XRP Ledger for quantum-resistant cryptography, with a target transition by 2028. This roadmap aims to safeguard accounts and transactions against potential threats posed by powerful quantum computers as they may eventually break the elliptic-curve cryptography currently in use across blockchain networks. Ripple's senior director of engineering, Ayo Akinyele, emphasized that this initiative is a multi-year infrastructure migration rather than a simple software patch. The first stage of the plan centers on contingency measures for the anticipated \"Q-Day,\" a point when quantum machines could potentially compromise public-key cryptography. Ripple is investigating a contingency mechanism that would halt acceptance of vulnerable classical signatures, providing a secure route for account holders to transfer funds to post-quantum accounts. One proposed approach involves using post-quantum zero-knowledge proofs, allowing users to demonstrate control of existing keys without exposing those keys during the migration.",
  "summary": "Ripple is moving ahead with a four-phase programme to prepare the XRP Ledger for post-quantum cryptography, targeting a transition to quantum-resistant signatures by 2028 while testing security mechanisms before a large-scale quantum threat becomes practical. The roadmap, set out by Ripple in April and detailed by its engineering team, is designed to protect accounts and transactions if powerful…",
