Ripple is targeting 2028 to make the XRP Ledger resistant to quantum computing threats. The timeline signals that cryptographic risk is no longer theoretical and is entering active infrastructure planning for long-duration digital assets.
The company disclosed the plan Monday, citing recent research from Google Quantum AI that intensified debate over future cryptographic vulnerabilities. Ripple stated that current assets remain secure but warned preparation timelines now matter as capabilities advance. The XRP Ledger, launched in 2012, underpins XRP, which carries a market capitalization near $100 billion.

Is Quantum Risk Becoming A Near-Term Priority For Blockchains?
Quantum computing risk is gaining broader industry attention, though views remain split on urgency and execution timelines. Bernstein described the issue as a “manageable upgrade cycle,” while some builders, including Tron’s founder Justin Sun, have begun outlining mitigation strategies. By contrast, Ethereum lacks protocol-level key rotation, a feature Ripple argues gives XRP Ledger structural flexibility.
“There’s a more subtle risk too, one researchers call ‘harvest now, decrypt later,’” Ripple said in its announcement. The firm explained that attackers could store encrypted blockchain data today and decrypt it once quantum systems mature. “The findings don’t point to an immediate break,” Ripple added, “but systems securing long-lived value need to start planning for a post-quantum transition.”
Still, not all market participants agree on the severity of the threat. Strategy chairman Michael Saylor has downplayed quantum risks, reflecting a broader divide between immediate mitigation and deferred upgrades. But does dismissing early signals risk underestimating long-term exposure for high-value networks?
Ripple is positioning XRP Ledger as comparatively prepared due to native key rotation, allowing users to migrate cryptographic keys without altering accounts. That design may reduce friction in a future transition, particularly if quantum-resistant standards emerge unevenly across networks. The next catalyst will likely come from formal post-quantum cryptography standards and whether major blockchains commit to implementation timelines.
