Ripple presented a step-by-step roadmap to adapt the XRP Ledger (XRPL) to a post-quantum scenario this year on April 20, 2026, with the aim of completing the transition in 2028 without compromising network operations.
The announcement comes amid increased attention to the risks quantum computing poses to today’s cryptography. Recent research by Google Quantum AI shows that in the future, Algorithms widely used in cryptography may be vulnerableaccelerating the cryptocurrency industry’s readiness plans.
Ripple’s strategy for post-quantum threats
Ripple proposes a progressive strategy divided into four phases. The first focuses on preparing for the eventual “Q-Day,” the moment when traditional encryption is no longer secure. In this scenario, the network Migration to post-quantum cryptographically secured accounts could be forcedThis includes zero-knowledge proofs that allow you to prove ownership of a key without exposing it.
The second phase is scheduled for the first half of 2026 and will include a risk assessment and Experimenting with algorithms that are resistant to quantum attacksespecially those recommended by NIST (a US organization that defines standards for encryption and cybersecurity). This process includes testing the impact on performance, storage, and operational costs within the ledger.
The third phase, scheduled for late 2026, will include: Gradual integration of these schemes in a test environmentworks in parallel with the current system. This will allow developers and ecosystem participants to evaluate its viability without impacting the main network.
Finally, the goal of the fourth phase is to Complete transition to post-quantum signatures by 2028. This process includes implementing new protocol fixes and extensive coordination with users, developers, and node operators to ensure an orderly transition.
“Harvest now, decipher later” problem
Ripple is aware of the so-called risks.Harvest now, decrypt later.” As reported by CriptoNoticias, the strategy is for malicious actors to collect currently encrypted data and decrypt it using more advanced quantum computers in the future.
Ripple claims that XRPL has structural advantages for this transition, such as native key rotation and deterministic generation of new credentials, which facilitates a gradual transition without the need to move funds to a new account. With this plan, the company seeks to anticipate risks such as: It’s not happening anytime soon, but it’s no longer theoretical.
This risk is not unique to XRPL. For example, in Bitcoin, millions of public keys are already exposed on the chain after being used in transactions, which opens the possibility, at least in theory, for public keys to be compromised in a quantum scenario.
Migration is also being discussed in the case of Ethereum. Although there are proposals to introduce resistant cryptography without changing the underlying protocol, the official roadmap does not yet have a specific deadline, and deeper structural changes may be needed.
let’s remember that The debate surrounding quantum risk is not new within the ecosystem. Prominent figures such as Blockstream co-founder Adam Back point out that the threat is not immediate and could take 10 to 20 years for the industry to adapt. Still, there is not complete agreement. Some organizations are accelerating transition deadlines, while others argue that the urgency does not yet correspond to the current state of quantum hardware.
