What is the essence of Proof of Stake decentralization?

Question

Cryptography

Good evening, actually. Let's say you have a network with several thousand active members. Let's say each of the thousand participants has generated a block and offers it to the network. On the technical side, who runs the "lottery"? Which node tells the rest that this or that participant has won?

Answer 1

Proof of Stake itself does not define the mechanism of operation, but only the concept. For example, in delegated proof of stake, each node uses the same algorithm for all, but which cannot be calculated in advance (the hash of the previous transaction is included in the shuffle function), based on the proportion of your coins and the total ranks the participants. And the first one will have time to form a block. If he does not, then the right passes to the next.
And if someone breaks the rules, forms a block himself and sends it to everyone, then they will not accept it, because according to their data, he did not have the right to do so.
