While the quantum computing threat has long been considered a theoretical risk in the cryptocurrency sector, recent research has made it a more concrete issue, and Ripple has taken a significant step in this area.
The company announced on Monday a multi-stage roadmap aiming to build a quantum-resistant structure for the $XRP Ledger (XRPL) by 2028.
Ripple’s plan envisions a gradual transition rather than a sudden overhaul of existing systems. This involves first testing quantum-resistant cryptography solutions, then deploying a hybrid model to work alongside the existing infrastructure, and finally scaling these systems. The company is also collaborating with Project Eleven to accelerate the development process, which includes validator testing and the development of early-stage storage prototypes.
One of the notable elements of the quantum threat preparedness plan was the emergency scenario called “Quantum-Day” (Q-Day). This plan includes a transition mechanism that would allow users to securely move their assets to quantum-resistant accounts in the event that current cryptographic standards are compromised.
Behind these developments lies a recent study published by Google Quantum AI. This research revealed that sufficiently advanced quantum computers could break existing cryptographic algorithms used in blockchains by 2032. These algorithms are critical for the security of wallets, transaction signing processes, and the protection of digital assets.
Although there is no direct risk today, experts say the threat has moved from being theoretical to a “credible” level. Specifically, in the so-called “collect now, decrypt later” scenario, malicious actors could collect open cryptographic data on the blockchain today and decrypt it in the future using quantum computers.

Ripple points out that this risk could have significant consequences specifically for XRPL. Every account connected to the network makes its public key visible on the chain when signing a transaction, and this could create a potential security vulnerability in the quantum age. Protecting accounts that hold assets for the long term is among the primary objectives.
On the other hand, it is added that XRPL already has some advantages. Thanks to the network’s built-in key rotation feature, users can switch to more secure keys over time without changing their existing accounts. This feature provides significant flexibility not found in many blockchains, allowing users to adapt to security updates without having to move their assets to new addresses.
Ripple officials state that the quantum transition is not a one-off update, but a comprehensive transformation encompassing performance, storage, usability, and protocol design. Therefore, the company is pursuing a multi-stage strategy aimed at minimizing disruption to the transition in a potential “Q-Day” scenario, while preserving the strengths of the current system.
