Ripple announced a plan today to protect the XRP Ledger (XRPL) from the potential threat of quantum computing by 2028. This move comes after Google cautioned that quantum computers could break current security systems as early as 2032, and surprisingly, with less computing power than previously thought – around 500,000 qubits.
Phases leading to a quantum-resilient Ripple and XRP
Ripple is preparing for a potential early arrival of “Quantum-Day” by developing backup plans. If this happens, they plan to implement a “hard shift” – temporarily blocking access to accounts using current security methods and allowing users to move their funds to accounts secured with quantum-resistant technology.
Starting in the first half of 2026, we’ll begin testing new, highly secure encryption standards recommended by NIST, working with Project Eleven to do so.
This assessment will show how adding post-quantum security features impacts the XRPL network, specifically how it affects transaction speeds, costs, and storage needs. Ripple will use these findings to make necessary changes to the network’s design, addressing the challenges presented by new post-quantum computing technologies.
The next step, planned for late 2026, is to test these features on Devnet. This will let developers check how well they work and how quickly they run, all without impacting the main network.
Ripple is also investigating how to use new privacy technologies, called Post-Quantum Cryptography, to better protect companies that are turning real-world assets into digital tokens.
Ripple will soon suggest updates designed to prepare its network for post-quantum cryptography. These changes have been tested and will be fully implemented once the community gives its approval.
Advantage over Bitcoin and Ethereum
Unlike Bitcoin and Ethereum, Ripple has a built-in feature that lets users update their security keys without needing to transfer their funds to a new account. This is particularly useful in protecting against potential future threats like quantum computing.
Transactions on XRPL are very fast, with new blocks added to the network every 3 to 5 seconds. This speed is a security benefit, as it limits the window of time that a user’s information could be exposed to potential attacks from quantum computers. This is much quicker than Ethereum (12 seconds per block) and Bitcoin (10 minutes per block).
As of today, XRP was trading at $1.43, a slight increase of 0.95% for the day. Charles Hoskinson, the founder of Cardano, claims that one reason Cardano hasn’t performed as well is because Ripple has been selling XRP to fund its own operations.
