Expand description

Start the mining worker for PoW. This function provides the necessary helper functions that can be used to implement a miner. However, it does not do the CPU-intensive mining itself.

Two values are returned – a worker, which contains functions that allows querying the current mining metadata and submitting mined blocks, and a future, which must be polled to fill in information in the worker.

pre_runtime is a parameter that allows a custom additional pre-runtime digest to be inserted for blocks being built. This can encode authorship information, or just be a graffiti.
