What this proves and what it cannot
It proves the keeper did not choose. The seed is fixed and published as a hash before the day starts, and the slot is named in the same memo. The randomness is that seed plus the blockhash of that slot, which nobody knows in the morning. Change either one afterwards and the published hash stops matching.
It cannot show you the list. The entrants are committed as a merkle root, not printed, because printing them is exactly what this coin does not do. A holder gets their own branch of that tree on the check page and verifies it in their own browser. The winner's address appears only if the winner asks for it.
