A mining client for Kadena Chainweb. It supports mining with ASICs through a stratum server, simulated mining for testing, multi threaded CPU mining, external mining workers (e.g. a GPU). Competitive mining on the Kadena Mainnet requires special mining hardware (ASIC), which connects to a Stratum Server from where it obtains work. All other mining modes (GPU, CPU, and simulation) are intended only for testing.
