A collaborative effort led by Eigen Labs and industry partners used AI agents to cut the theoretical resource demands for a quantum attack on Bitcoin and Ethereum signatures by 86%.
A team of over 100 researchers, using both AI coding agents and human expertise, has dramatically reduced the estimated resource cost of a quantum computer attack on Bitcoin and Ethereum’s secp256k1 signature scheme, cutting prior benchmarks by 86%.
Inside the Quantum Security Benchmark Drop
The research, led by Eigen Labs in partnership with Trail of Bits, StarkWare, Theta Labs, MultiVM Labs, and the Ethereum Foundation, targeted a key cryptographic step in so-called quantum attacks. They collaborated as part of ECDSA.Fail—a competition where designs are rated based on the product of logical qubits and Toffoli gates, both essential measures of quantum computation demands. The new benchmark, achieved between late May and July 26 and published only recently, dropped from 10.75 billion resources to 1.5 billion. One leading design used just 1,151 logical qubits with about 1.3 million Toffoli gates—nearly half the score of Google Quantum AI’s March estimate, although direct comparison is tricky since methodologies vary.
The project introduced Open Autoresearch, where humans and AI agents rapidly iterate solutions toward a quantifiable security target as a kind of red-team/blue-team exercise. For context, Bitcoin and Ethereum’s secp256k1 elliptic curve signature is widely seen as vulnerable to sufficiently powerful quantum computers, which in theory could extract private keys from public signatures.

Why Security Professionals Are Taking Notice
What makes this development notable is not just the technical innovation, but the source: security teams from inside crypto are making it easier to understand—and potentially accelerate—the real quantum threat timeline. The argument is explicit: only by knowing how efficiently an attack can be mounted can developers set sensible defensive priorities. As Ethereum eyes a hard December 2029 cutover to quantum-resistant infrastructure and StarkWare demonstrates quantum-safe transactions on Bitcoin’s mainnet, the stakes are growing for stakeholders across the ecosystem.
In broader market context, breakthroughs in quantum attack efficiency put pressure on the status quo. Security upgrade cycles, long measured in years, may soon require much faster turnarounds, challenging budgeting and strategic planning for institutions and individual holders alike.
Signals Worth Tracking in Crypto’s Quantum Race
- Monitor the pace of post-quantum cryptography deployments—actual migration beats theoretical planning for security.
- If further circuit design gains appear, quantum threat windows could shrink faster than asset custodians expect.
- Watch for ecosystem-wide disclosures or joint security funds as the sense of urgency mounts.
- Track how regulatory frameworks evolve to guide legacy holders through quantum-resistant transitions.
The Road Ahead for Crypto Security Alignments
The industry’s pivot to quantum resistance is now as much about timing as technique. Expect further waves of research aimed at squeezing resource requirements for attacks lower still—and rapid experimentation with quantum-safe cryptographic techniques on testnets and mainnets. Investors and security professionals will be watching for the first major chain, fund, or institution to announce live quantum-ready infrastructure. Until then, the battle over timing—can security upgrades outpace attack efficiency—will set the direction for everyone with assets at risk.

🧠 HafidWatch Take
If actual quantum hardware demonstrations reveal that attacks can bypass not only resource estimates but also fundamental assumptions about error rates or qubit coherence—in ways that cannot be mitigated by incremental optimization—then this article’s framework underestimates the scale and nature of the threat. Such a finding would invalidate the premise that improved resource efficiencies directly translate into manageable security timelines, exposing a conceptual flaw rather than a mere timeline adjustment.
A relevant historical example is the introduction of side-channel attacks against smartcards in the late 1990s, where practical exploitability shattered prevailing cryptanalysis assumptions. Despite years of rigorous mathematical security proofs, the cryptographic community had to fundamentally rethink threat models, emphasizing that real-world attack vectors often emerge from unexpected physical or implementation details rather than pure theoretical advances.
