Guy beats one of the best published quantum circuits for breaking ECDSA with AI(twitter.com)
I beat one of the best published quantum circuits for breaking Bitcoin. And I have no formal training in quantum cryptography. Using just AI agents, I improved it by ~2x. But I haven’t beat Google’s best classified circuit yet. So, today I'm launching ecdsa(dot)fail -- an open https://t.co/pbyqGSPP71

"All opinions expressed here are my own and do not represent the official views of my employer. On the other hand, I obtained approval from my employer for presenting at the academic conference (JSME). Basically, the information provided will be limited to what is stated in the announcement." We have developed a spatial dimension measurement device and motion capture (orientator) using airborne ultrasonic waves. We achieved spatial measurement by using 3 ultrasonic transducers and 3 ultrasonic microphones. The measurement principle is based on 3 sets of 3-side measurements. We acquire plane equations of microphones and transducers, and calculate the orientation angle and direction based on the surface normal vector. It is expected that this device can instantly measure the positional relationship of pipes, etc. at plant construction work with displaying the 3D data on PC in real time.
