Ethereum 2.0 adopts the pos consensus mechanism. How does it motivate people to pledge tokens and how to ensure the security of the network? What is the appropriate issue rate? What do you think about the economics of Ethereum 2.0?
Ethereum 2.0 pos consensus mechanism related to the Hybrid Casper FFG. that consensus will not eliminate the miners but that will create a hybrid consensus miners are still needed but POS mechanism will create some emission to be distributed to the ethereum stakers. Miners still active to help POS system to secure the network. But it's still on the discussion by ether dev. The final block reward for miners will be 0.5 eth.
It's actually a very good development by the ethereum team, at least it shows that they are working hard and always committed to making the project work at all cost, now let's just wait and see what will come into the crypto community now that eos have gone the pos way, maybe we might see a bull run in the price of eth in no time and also see the issue of scalability being solved, all I can do now is hope for the best for all the ethereum fans, wish you lots of bull run ahead.
