While the quantum computing threat has long been considered a theoretical risk in the cryptocurrency industry, recent research has made it a more concrete problem, and Ripple has taken an important step in this area.
The company announced on Monday a multi-step roadmap aimed at building 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 with existing infrastructure, and finally scaling these systems. The company is also collaborating with Project Eleven to accelerate the development process, which includes validation testing and early-stage storage prototype development.
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 found that sufficiently advanced quantum computers could break existing cryptographic algorithms used in blockchains by 2032. These algorithms are essential for wallet security, transaction signing processes, and the protection of digital assets.
Although there is no direct risk today, experts say the threat has moved from the theoretical stage 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 highlights that this risk could have significant consequences specifically for XRPL. Every account connected to the network makes its public key visible on-chain when signing a transaction, which could create a potential security breach in the quantum age. Protecting accounts that hold long-term assets is one of the main objectives.
On the other hand, we add that XRPL already has certain advantages. With the network’s built-in key rotation feature, users can gradually upgrade to more secure keys 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 say the quantum transition is not a one-time update, but an overall transformation encompassing performance, storage, usability and protocol design. Therefore, the company is pursuing a multi-step strategy aimed at minimizing transition disruption in a potential “Q Day” scenario, while preserving the strengths of the current system.
