Ripple revealed a plan to make XRP secure against future quantum computers. This four-step process aims to fully protect the XRP Ledger by 2028. The move comes after Google Quantum AI’s research suggested that today’s blockchain security could be vulnerable to powerful quantum computers.

Summary

  • Phase 2 is already underway in the first half of 2026, with Ripple’s applied cryptography team testing NIST-standardized algorithms in partnership with quantum security firm Project Eleven.
  • Phase 3, planned for the second half of 2026, will deploy candidate post-quantum signature schemes alongside existing signatures on Devnet for developer testing without affecting mainnet.
  • Phase 4 targets a full network amendment implementing native post-quantum cryptography by 2028, with a focus on throughput optimization and coordinated migration across all XRPL participants.

XRP Ledger (XRPL) now has a clear, public plan to prepare for the potential threat of quantum computing. Ripple announced the four-step plan on April 20th, making XRPL one of the first major blockchain networks to commit to a formal schedule for upgrading to quantum-resistant security. This move comes after research from Google Quantum AI indicated that future quantum computers—potentially around 500,000 qubits—could break the current encryption that protects most blockchains, with some experts predicting this could happen as early as 2029.

Ripple has clarified that the threat isn’t happening right now. However, they emphasize the need to prepare for a potential future attack called “harvest now, decrypt later.” This involves hackers collecting and saving encrypted data from blockchains today, with the intention of unlocking it once quantum computers become powerful enough. This is a significant concern for digital assets held for the long term – years or even decades.

The Ripple team explained they’re not only focused on what’s secure from a cryptography standpoint, but also on what will actually work well for the XRPL network as it grows. They see their future plans as an engineering problem to be solved, not just a matter of cryptography.

The Four Phases of Ripple’s Roadmap

The first phase, called Q-Day readiness, isn’t a planned event, but a precaution for an emergency. If quantum computers become powerful enough to break current security systems sooner than anticipated, Ripple will implement a “hard shift.” This means the network will no longer accept standard security signatures, and everyone will need to move their funds to accounts protected against quantum computer attacks. Using advanced post-quantum cryptography, account holders will be able to prove they own their funds and regain access without revealing any potentially compromised security information, ensuring no one loses access to their money.

I’m really excited about the progress Ripple’s making with post-quantum cryptography! Phase 2 is now live, and their cryptography team – including Dr. Murat Cenk, Dr. Tamas Visegrady, and Dr. Aanchal Malhotra – is actively testing these new, NIST-approved algorithms directly on the XRPL. They’re looking at how these changes impact things like transaction size, storage needs, network speed, and overall performance. Plus, Project Eleven is helping out by testing at the validator level and even building a prototype for a post-quantum custody wallet. It’s great to see them preparing for the future of crypto security!

Starting in the latter half of 2026 (Phase 3), we’ll introduce potential post-quantum signature methods on our test network (Devnet) alongside our current systems. This allows developers to evaluate how these new methods perform and affect the network without impacting the live network. By 2028 (Phase 4), we plan to officially integrate post-quantum cryptography throughout the network with a formal update.

Why XRPL Has a Structural Head Start

The XRP Ledger has two built-in features that make it better prepared than Bitcoin and Ethereum for future technological changes. First, XRPL lets users easily update their security keys without having to create new accounts or move their funds. Ethereum doesn’t have this ability built-in, so updating security on Ethereum would require everyone to manually transfer their assets to new accounts.

Furthermore, the way XRPL generates keys – using a seed – makes it possible to reliably create new cryptographic material, which is crucial for updating the network’s security. XRPL engineer Denis Angell has already successfully tested ML-DSA, a quantum-resistant signature method, on XRPL’s AlphaNet. This shows that the technology needed for the next phase isn’t just a plan, but is actually working.

What This Means for XRP Holders and the Broader Market

There’s ongoing disagreement within the crypto industry about how to prepare for the potential threat of quantum computing. Bitcoin developers can’t agree whether to offer optional upgrades or require changes to the system, while Ethereum is quickly moving forward with a planned series of improvements. Ripple, with its clear and organized strategy, gives the XRPL blockchain an edge when it comes to attracting institutions, which need reliable, long-term infrastructure before they’ll invest.

The XRP ETF market saw $119.6 million in new investments last week (ending April 11th). A clear plan to protect against future quantum computing threats strengthens the case for long-term investment in XRP. Institutional investors who plan to hold these ETFs for several years need to be sure the XRP network will remain secure for the duration of their investment.
