Ripple has unveiled a comprehensive four-phase plan to safeguard the XRP▼$1.19 Ledger against quantum computing threats.
The company has rolled out a multi-year plan to transition to quantum-resistant algorithms to protect long-term holders’ assets. According to a Ripple report, developers plan to fully migrate the infrastructure to new security standards by 2028.

Company representatives noted that the quantum computer threat has moved from theoretical to practical. The main danger is the “store now, decrypt later” tactic, where attackers copy encrypted data from the public ledger today to break it later.
Risks of Delayed Decryption
Ripple’s team acknowledged that the danger of quantum computers breaking blockchains has moved from theory into practical planning. The main problem, they said, lies in the “store now, decrypt later” tactic.
“Attackers can copy encrypted data from public ledgers today to break it in a few years when equipment becomes powerful enough. All investors whose accounts remain inactive for long periods are at risk,” Ripple analysts noted.

Transition Phases
The migration plan is divided into four phases:
- Emergency recovery: developing a mechanism for rapid migration to protected accounts in the event of a sudden quantum threat (Q-day).
- Experiments (first half of 2026): testing new algorithms recommended by NIST and prototyping quantum-resistant wallets.
- Integration (second half of 2026): implementing new signature schemes on the Devnet test network.
- Full transition (2028): releasing an official protocol amendment and mass network migration to post-quantum signatures.

XRPL Advantages
Ripple emphasized that the XRP Ledger’s architecture is inherently more flexible than many other blockchains. The network already has key rotation functionality, and seed-phrase key generation allows deterministic creation of new keys. This simplifies the transition to new security standards.
Additionally, the company is exploring the use of homomorphic encryption to enhance transaction privacy and support confidential transfers.
“This phase is where experimentation meets system design. We’re not just asking ‘what works cryptographically?‘ We’re asking ‘what works for XRPL at scale,‘” the Ripple team noted.
