Sean sent me a challenge in private communication today, and I uploaded a response on the same day.
I used the ebfull/powersoftau repo at d47a1d3d1f007063cbcc35f1ab902601a8b3bd91, using the latest stable Rust (1.23.0). I downloaded the challenge on two separate machines (desktop PC and laptop), disconnected one of them from the network and ran compute on both. I flipped a coin and chose one of the resulting hash+response pairs, and copied it over to a flash drive. I removed the traces from both machines, rebooted them and ran a Memtest. I uploaded the response from a third machine, from which I am also sending this email + tweet.
