So I am trying to wrap my head around Proof of History and how it is used in Solana.

I am reading the white paper. https://solana.com/solana-whitepaper.pdf

And so far I think I get the general idea of it. An iterative hashing, which produces intermediate hash (that can be indexed) that is then fed into the hashing etc.

The fact that each step of the iterative hashing with the index is kept makes it possible to verify this iterative hashing faster than the actual production.

All these is good.

The part I start loosing it is when it starts talking about Timestamp for Events and how does this fits into the mechanism for building and verifying blocks and also for leader selection

For example in the paper i read:

The Leader sequences user messages and orders them such that they can be efficiently processed by other nodes in the system, maximizing throughput.

I understand the proof of history, but here I do not get how that factor or can be used to "sequences user messages and orders them"
