A crowdsourced challenge involving over 100 researchers and AI agents reduced the quantum computing cost of a key step in attacking Bitcoin and Ethereum by 86% in two months, achieving a score well below Google's previous benchmark. The optimized point-addition circuit for the secp256k1 elliptic curve now requires fewer logical qubits and Toffoli gates, shrinking the quantum attack margin. While this does not enable an immediate attack, it highlights the urgency for blockchain networks to accelerate post-quantum security measures, with Ethereum targeting 2029 for full quantum resistance. Experts emphasize that the threat is now driven by both hardware and algorithmic advances, underscoring the need for early migration across blockchain systems before practical quantum attacks become feasible.
