Really pleased to finally see a possible alternative to the atrociously wasteful proof-of-work algorithms. Here's hoping bitcoin will switch, too.

The whole point of PoW is to be expensive. The security of the network is a derivative of the cost of running the nodes.

PoS is also expensive but the expense is in opportunity cost not in capex and energy. There's clean expensive and dirty expensive.
