I have submitted a pull request for doing a deterministic build of the Golang powersoftau implementation. The pull request is here: https://github.com/FiloSottile/powersoftau/pull/4 . The guest OS is Debian 9 (stretch), due to the requirement for Golang 1.7+.
This was tested as follows: - Ubuntu 17.10 host with Virtualbox - Ubuntu 16.04 host with LXC Other combinations may work, but KVM is known to not work with a Debian guest. Until this is merged, you can follow the README but clone my branch instead: git clone email@example.com/golang-powersoftau Please try to replicate my resulting SHA256 hash: c28894877c8948960eaefa0d8f35da6c911031980672b983f361711a7dcb1ec8 taucompute
