+
+Procedure
+=================
+
+* followed the instructions provided by Sean Bowe
+* downloaded [Powers of Tau](https://github.com/ebfull/powersoftau) with commit d47a1d3d1f007063cbcc35f1ab902601a8b3bd91
+* downloaded the challenge file from an [Amazon S3 bucket](https://s3-us-west-2.amazonaws.com/powersoftau/hysxgqp8Ca1JAMgRtolqKznDzzBrfdxW/index.html)
+* used verion of rustc 1.23.0-nightly (5041b3bb3 2017-11-19)
+* computed the response locally by running `cargo run --release --bin compute` on macOS 10.13.1

+
+Side channel defenses
+=================
+
+Entropy source: I smashed my keyboard to the beat of my current music in random places.
+
+I have no intention to destroy the compute node.
+
+I happily kept coding on [Tendermint Core](https://github.com/tendermint/tendermint) during the computation.
