XRPL Sets 2028 Target for Quantum-Resistant Security as Researchers Halve Attack Benchmark
The XRP Ledger has a stated target of 2028 to achieve quantum readiness, placing it ahead of Ethereum's 2029 target and in contrast to Bitcoin's currently undefined timeline. Separately, new research has cut the estimated quantum computing resources needed to attack elliptic-curve cryptography used by major blockchains by more than half, tightening the window for networks to upgrade their cryptographic foundations.
A target date of 2028 has been cited for the XRP Ledger to become quantum resistant, placing it one year ahead of Ethereum's publicly stated 2029 goal. Bitcoin has no confirmed quantum-readiness roadmap, leaving its long-term cryptographic security an open question for holders and institutions evaluating multi-asset exposure.
The urgency behind these timelines has increased following new academic research that reduces the estimated quantum resource threshold for attacking elliptic-curve cryptography, the cryptographic basis for most major blockchains. The new benchmark for a core calculation in Shor's algorithm came in at less than half the level previously reported by Google, according to researchers whose work was shared with crypto news outlets. The two approaches use different accounting methods, which adds some complexity to direct comparisons.
The research was produced with human-AI collaboration and represents a meaningful step forward in quantum computing capability relevant to blockchain security. Networks that reach quantum-resistant cryptography earlier will have a structural advantage if quantum hardware continues to advance on its current trajectory.
