Tendermint consensus: Are validators "known" and "pre-selected"?

0

What are similarities and differences between Tendermint consensus and Proof-of-Stak?

For example, in both consensus, a validator is selected randomly (I think in Tendermint consensus they are selected in a round robin process).

And I think in Tendermint consensus, validators are known and pre-selected, unlike Proof-of-Stake consensus. Is it true? and if yes, what entity does confirm a known validator?

Yes they are known. They are selected via a round-robin fashion. The Tendermint team intend to add a VRF to randomly select validators:

Thank you. So, do it mean that there is a finite set of "pre-selected" validators (permissioned)? OR everyboby is permitted to join set of validators (permission-less)? Thanks – Questioner – 2018-10-21T13:54:20.743
