Glad I found this through @amariespeaks' Minnow Mondays.
I'm not a crypto techy so I like how you explained GoChain in such a way that will be understood by someone like me. I like that they will use Proof of Repution which will lead to a more decentralized consensus and not just one big group of miners. As you explained, Proof of Work is costly and energy consuming too which makes them expensive too.
