I have always preferred the consensus protocol of Proof-of-Stake compared to Proof-of-Work because i believe that true decentralization is achieved on PoS. Just recently the Ethereum Network upgraded to PoS consensus mechanism yet i have not heard about the specific collateral coins that would be required by the network to host a node. I would like to know how they intend to use the PoS as its consensus protocol knowing that currently its supply is not capped yet.
