..but still I could manipulate the players pool so that would not give you any guarentees that it would be fair.
No, "the players" are just bitcoin transactions. So everyone would have the same list of players in the same order (for example: confirmed transactions between block x and x - ordered alphabetically by transaction hash.) Then the result will be based on that block hash of that specific future block x. This way everyone can run a (simple) script to verify the results and be sure that the winner is selected fairly.
Imo random is fine.
Your opening statement says otherwise:
However like alot of you I sometimes wonder if the website/service is 100% legit and payouts are real as often noone on this board won anything.
If the game is provably fair, you don't have to wonder if the results are "legit" and you don't have to trust the site owner (for the bet/lottery result), because everyone can calculate it themselves
This is way superior than just "
trusting you to pick a random winner".
I think if you google a bit on PevPot or "dabs lotto" you might find some previous provably fair lotteries (that stopped already) for their exact calculation methods.
And like hilariousandco says, unfortunately there are just too many scammers here - even for tiny amounts. It's not a personal attack to you
just really how anonymous internet works. Not interested in meeting up in Amsterdam lol.
..but yet want to stay and bitch about the dodgey payouts some bitcoin casinos have?
The "bitcoin casinos" that mostly have traditional non-provably fair games and sketchy licenses with unclear house edges that unfortunately do score high in Google - are indeed bad. But there are plenty of good bitcoin gambling sites around, mostly dice sites and some sites like bustabit. These sites actually have a better payout than your lottery (mostly only 0.3 - 1% house edge) and are provably fair too. Most of the bitcointalk audience seem to prefer these sites over those "sketchy bitcoin casinos" afaik.
