Is there any firm date for ETH to move over to Proof of stake. Will it be a total transfer or gradual, mixed mining. I know some coins mix both, OFW is one I can think of though thats very unknown apparently it can be the case that both methods are used long term.
Im not sure if ETH definitely will goto POS or its just a backup plan left on the shelf and likely wont occur
Still, there is no official announcements from the authorities only people are talking about the POS model. We need to wait for official announcement instead of spreading the news. I hope it is a best plan if they implement ETH in POS model.
