Building timelords

The Linux and MacOS chiavdf binary wheels currently exclude an executable required to run a Timelord. If you want to run a Timelord on Linux or MacOS, you must install the wheel from source (which may require some additional development packages) while in the virtual environment.

. ./activate

sh install-timelord.sh

If the compile fails, it's likely due to a missing dependency. install-timelord.sh attempts to install required build dependencies for Linux and MacOS before invoking pip to build from the source python distribution of chiavdf.

The install-timelord.sh install script leverages two environmental variables that the chiavdf wheels can use to specify how to build. vdf_client is the service that the Timelord uses to run the VDF and prove the Proof of Time. vdf_bench is a utility to get a sense of a given CPU's iterations per second.

• To build vdf_client set the environment variable BUILD_VDF_CLIENT to "Y". export BUILD_VDF_CLIENT=Y.
• Similarly, to build vdf_bench set the environment variable BUILD_VDF_BENCH to "Y". export BUILD_VDF_BENCH=Y.

Building and running Timelords in Windows x86-64 is not yet supported.
