And as far as I can tell, non-proof-of-work cryptocurrency is mostly a mirage or even a deliberate red herring / bait-and-switch.
Polkadot has working proof-of-stake. Polkadot has a setup where it can run many more transactions then Ethereum can with the current 1.0 setup. If you don’t believe that Ethereum will manage the transition to Ethereum 2.0 then it would be likely that Polkadot overtakes Ethereum for DeFi.
Filecoin has a type of proof-of-work but it’s work that stores files with is economically useful.
