XRP Ledger targets full quantum resistance by 2028

XRP Ledger is entering a new phase where long-term infrastructure priorities, especially quantum resistance, are taking center stage. Security, tokenization, and autonomous software processes are all under review as RippleX’s engineering head, J. A. Akinyele, stresses that this focus on infrastructure can no longer be postponed.

A multi-stage roadmap for quantum readiness

In a 2 minute 13 second video shared on RippleX’s official social media, Akinyele explains that what the industry calls “Q-day” is no longer just a theoretical risk, but an accepted eventuality. The main concern is that a sufficiently advanced quantum computer could eventually overcome today’s cryptographic foundations.

Mini glossary: Q-day refers to the hypothetical day when quantum computers become capable of breaking mainstream public-key encryption methods. Post-quantum cryptography encompasses new cryptographic techniques designed to withstand attacks from both traditional and quantum computers.

Akinyele says that XRP Ledger is taking a proactive approach to potential quantum attacks, and that preparations could extend over several years. With full quantum readiness targeted for 2028, Akinyele emphasizes that this is more than a technical update—it should be viewed as an “architectural transition” for XRP itself.

Three key phases and an emergency plan

The RippleX engineering team outlines quantum readiness in three major phases alongside an emergency contingency plan. This contingency plan aims to move existing accounts to a post-quantum secure version, creating a migration pathway to deter attacks from quantum-enabled adversaries attempting to steal assets.

The first phase will test standardized post-quantum digital signatures and determine which signature structure is most suitable for XRPL. This stage also involves evaluating each security model from both technical and operational perspectives.

Selection, integration, and migration across the ecosystem

In the second phase, the chosen signature scheme will be integrated into the ledger, with its reliability, security, and decentralization rigorously assessed to meet XRPL’s standards. The third phase covers migration across the entire ecosystem, requiring coordinated action from network stakeholders.

Akinyele notes that after the third phase, extensive feedback will be gathered and the developed framework will be updated iteratively. The fact that XRPL already possesses essential components for this advanced transition could make future upgrades smoother. As an open-source blockchain infrastructure used for payments, tokenization, and a variety of digital asset applications outside the Ripple ecosystem, XRP Ledger is uniquely positioned for this evolution.
