toluTag is an open-source passive NFC tag using NXP SE05x secure elements to sign ECDSA messages verifiable on Ethereum, enabling physical objects to authenticate on-chain without requiring central servers or extractable private keys.
Researchers propose Open Autoresearch, a paradigm combining human and AI efforts to optimize elliptic-curve point-addition circuits for Shor's algorithm on quantum computers. Participants reduced the spacetime score by 86.1%, achieving circuits using 1,151 qubits and 1,299,453 Toffoli gates, surpassing Google's published thresholds.
