Project Eleven Quantum Threat Report
Analysis based on 7 articles · First reported May 06, 2026 · Last updated May 06, 2026
The report by Project Eleven highlights a significant future threat to the blockchain ecosystem, including Bitcoin, from quantum computing. This could lead to increased investment in post-quantum cryptography solutions and potentially impact the long-term valuation of cryptocurrencies if mitigation efforts are not perceived as adequate.
Project Eleven released 'The Quantum Threat to Blockchains 2026 Report' on May 6, 2026. The report provides an analytical framework for measuring progress toward a cryptographically relevant quantum computer (CRQC), setting a baseline for 'Q-Day' at 2033, with optimistic and pessimistic scenarios at 2030 and 2042. Alex Pruden, CEO of Project Eleven, stated the report explains how quantum computers work and models their progress. Fontaines D.C., CTO of Project Eleven, emphasized the vulnerability of major blockchains, including Bitcoin, that rely on elliptic curve signatures, urging them to begin redesigning their systems for post-quantum signatures. The report also references research from Alphabet Inc. and Oratomic that has reduced the estimated resources needed to break cryptographic algorithms.
