We all know that proof-of-work is energy intensive, which means that cryptocurrencies such as Bitcoin and Ethereum currently have to defend themselves against charges that the environmental damage they are causing is not outweighed by the current or future benefits they offer.

This means that if someone sees no value in a decentralized currency/store of value/whatever the cryptocurrency is ... then you can't win the argument.

Ethereum has taken the approach that side-stepping to proof-of-stake, thereby removing the attack, is the best approach.

But how good is proof-of-stake as a replacement for proof-of-work?

Listen to this episode to see what I think.
