Catenaa, Friday, April 24, 2026- Ripple said it plans to make the XRP Ledger fully quantum-ready by 2028 as concerns grow that advances in quantum computing could eventually threaten the cryptography that protects blockchain networks.
Ripple said the threat has shifted from theoretical to credible, even though digital assets are not currently at risk. The company pointed to recent research from Google Quantum AI showing that the amount of computing power needed to crack common cryptographic systems has fallen sharply.
Ripple warned of a “harvest now, decrypt later” scenario, where attackers collect blockchain data today and wait for future quantum computers powerful enough to unlock it.
The company said it will roll out a four-phase roadmap. The first stage focuses on contingency planning and a “Quantum-Day” migration plan. The second phase, in the first half of 2026, includes testing post-quantum cryptography standards recommended by the US National Institute of Standards and Technology.
Ripple said the third phase will begin later in 2026, when developers test hybrid signature systems on the XRP Ledger developer network. The final phase targets a full network transition by 2028.
Ripple said the XRP Ledger already has an advantage over many rival blockchains because it supports native key rotation. That means users can change cryptographic keys over time without changing wallet addresses or moving funds.
The company argued that this gives the XRP Ledger a more direct path to quantum migration than networks such as Ethereum, which do not have a built-in equivalent.
Ripple is also working with Project Eleven on validator testing, developer network benchmarking and quantum-safe wallet prototypes. The goal is to test larger signatures, storage needs and transaction speeds before a wider rollout.
Why It Matters
Quantum computing remains years away from breaking blockchain security, but recent research has shortened the estimated timeline. Some researchers say future machines could potentially crack common blockchain encryption in less than 10 minutes, creating risks for assets secured by exposed public keys.
That has led several crypto firms to begin preparing for a post-quantum future. Ripple is positioning the XRP Ledger as an early mover, while other blockchain communities are only beginning to discuss long-term defenses. Some market observers believe networks that prepare earlier could gain an institutional trust advantage.
The XRP Ledger is a public blockchain launched in 2012, with Ripple acting as its main contributor. XRP is currently one of the largest cryptocurrencies by market value.
For years, quantum computing risks were viewed as a distant issue for crypto. However, recent advances in hardware, error correction and cryptographic research have increased concern that blockchain systems may need upgrades sooner than expected.
Ripple’s roadmap reflects a wider industry shift toward post-quantum cryptography, particularly for networks holding long-term value or supporting institutional finance.
