Catenaa, Wednesday, May 13, 2026- Quantum security startup Project Eleven warned Wednesday that a breakthrough capable of cracking modern encryption could arrive as early as 2030, raising fresh concerns across the cryptocurrency industry and broader technology sector.
Q-Day Forecast
The firm said the so-called “Q-Day,” when quantum computers can defeat widely used cryptographic systems, is now more likely than not by 2033. The estimate reflects accelerating progress in both quantum hardware and algorithms.
Project Eleven argued advances may arrive suddenly rather than gradually. The report described the path as “nothing, and then all at once,” warning that current assumptions about a slow rollout may underestimate the risk.
The report estimated about 6.9 million bitcoin, worth more than $560 billion at current prices, could face quantum-related threats under certain conditions. Bitcoin’s existing cryptography relies on elliptic curve encryption, which powerful quantum systems may eventually defeat.
Researchers recently demonstrated a partial breakthrough by deriving a 15-bit elliptic curve key using quantum hardware. While far below the 256-bit encryption standard used in Bitcoin, the experiment highlighted steady progress in the field.
Project Eleven said the crypto industry could face a race against time because shifting users toward quantum-resistant wallets may take years. The report referenced Mosca’s inequality, a theory suggesting systems become vulnerable if upgrade timelines exceed the pace of emerging threats.
Several proposals have already emerged.
Industry Responses
Dan Robinson recently proposed a timestamp-based recovery system that could help Bitcoin holders reclaim funds on a future quantum-safe network.
Another proposal, BIP-361, backed by Jameson Lopp and others, outlines a multi-year migration process to move assets into quantum-resistant addresses.
The issue extends beyond crypto markets. Google has already accelerated plans to migrate toward quantum-resistant cryptography by 2029 as governments and technology firms prepare for future security risks.
The report adds pressure on developers, exchanges and infrastructure providers to prepare before quantum breakthroughs move from theory into practical deployment.
