QDay Prize is an open competition focused on quantum cryptanalysis, challenging participants to break the largest elliptic curve cryptography (ECC) keys using Shor's algorithm on quantum computers. This initiative addresses the growing need to understand the vulnerabilities of current encryption standards as quantum computing advances. The competition is organized by Project Eleven (P11) and does not require participants to be affiliated with any institution. Participants are tasked with using quantum computers to crack ECC keys, which are widely used in securing Bitcoin wallets and TLS encryption on the web. The competition aims to measure how close we are to breaking ECC, which is favored for its efficiency, providing the same security as traditional schemes like RSA but with much smaller key sizes. Participants must submit full logs, circuit details, and validation data to prove their use of quantum computers. The QDay Prize is supported by a group of cryptographers, quantum computing pioneers, and industry leaders who ensure the competition's integrity.
