[Digital Today reporter Jinju Hong] XRP Ledger (XRPL) has begun a long-term infrastructure transition to prepare for the era of quantum computers. RippleX described it as an "architectural transition" that changes the network structure itself, rather than a simple security update, and released a phased roadmap.

On June 13 (local time), blockchain outlet U.Today reported that RippleX engineering head J. A. Akinyele (J. A. Akinyele) said XRPL's quantum response strategy is a core infrastructure project to be carried out over the coming years.

In a video released on RippleX's official social media channels, Akinyele said the industry no longer views Q-Day as a hypothetical event. He said studies have continued to show that sufficiently advanced quantum computers could neutralise current cryptographic systems.

Q-Day refers to the point at which a quantum computer can effectively decrypt existing public-key cryptography. Major blockchain networks, including Bitcoin, Ethereum and XRPL, currently protect assets and accounts based on public-key cryptography.

To respond, RippleX is building quantum-resistant infrastructure alongside work on security, tokenisation and agent-based workflow development, and set 2028 as the target for a complete quantum response system. Akinyele stressed that the work could take several years and requires sufficient preparation time because it involves infrastructure-level change.

The roadmap released by RippleX consists of an emergency planning stage and a three-stage transition plan. In the emergency stage, existing accounts will be migrated to a quantum-resistant, secure account structure. The goal is to minimise the risk that attackers with quantum computers could steal assets using existing public keys.

In stage 1, it will test a standardised signature scheme that can be used in the post-quantum era. This is a process of reviewing and evaluating quantum-resistant signature algorithms best suited to XRPL.

In stage 2, the selected signature scheme will be integrated into XRPL. It will then undergo verification to check whether security, reliability and the level of decentralisation meet network requirements. Akinyele described this stage as a section where implementation and verification occur together.

Stage 3 is the transition of the entire ecosystem. Network participants such as exchanges, wallet services, developers and validators will move to the new system, and continuous improvements are to be made by reflecting feedback arising in actual operations. Akinyele said ecosystem migration is not a simple technology rollout but a task that must proceed with collaboration and iterative improvement.

The market is paying attention to the fact that XRPL has begun treating the threat of quantum computers as a practical operational task rather than a theoretical risk in the distant future.

It is also notable that RippleX is approaching quantum readiness as a network architecture overhaul rather than adding individual features. Akinyele stressed, "If infrastructure is this important, we can no longer wait."

XRPL believes it already has the basic components to support account migration and long-term upgrades, and expects the transition process to become smoother as network participation expands.

Industry interest is focused on which quantum-resistant signature scheme will ultimately be adopted, what verification procedures will be applied in the ledger integration process, and how actively ecosystem participants such as exchanges and wallet operators will take part in the transition work.
