Ethereum 2.0 is POS apparently. I haven't figure out how to get onboard yet though. I have to do a bunch of homework to figure out what the hell means what. I don't have 32 ETH ($70k odd USD) so I have to join a staking pool but then that means I won't be running a validator I think. In which case this seems like simply just buying some ETH2.0 but it clearly isn't... so I have no idea honestly... More homework required on my part. Anyone have a good link with an overview of the moving parts AND motivations of the ETH2.0 structure?
