Which is a language I absolutely adore, and am building a homomorphic encryption based product leveraging Hyperledger on a rather obscure 160 hardware thread POWER8 server; it can definitely work for real production tasks today, even if some parts are rough (and hell, C++ can be rough too). Parallel compilation on this machine is stupidly quick :)

Any pointers to what power hardware you are running?

You don't need pointers - just follow the fan noise from wherever you are.
