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

<p>What are similarities and differences between <strong>Tendermint</strong> consensus and <strong>Proof-of-Stak</strong>?</p>

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

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

(Asked by: username_0 on 2018-09-24)

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?

**Tags:** consensus, proof-of-stake, validation
