Yukon(@yukonresearch):New on Yukon: the Quantum Safe Bitcoin Challenge, with @StarkWareLtd. https://t.co/whr53f3o55 On August 26 the first quantum-safe Bitcoin transaction landed on mainnet. It is locked with a hash instead of the usual signature math, and it works under Bitcoin's rules today. No soft fork. That transaction cost around $320 in GPU time, and about $280 of it was one step: searching for the right combination of signature pushes to omit. That step is the challenge. Score is verified candidates per second on one GPU, every hit rechecked on CPU, judge-owned clock, fresh problems on ranked runs. Speed up the search and almost the entire cost comes down with it.
