i used already enough red ink
in my first reply , read it if you missed BUT
those three words need expanding urgently :
JUST provably fair
here it comes , my first ORIGINAL TEXT in this thread , enjoy !
JUST provably fair for Dummies and ... Experts !
lets go back five-ten years
a bright idea came into the light after the shocking innovation of Bitcoin
people always complaining about fairness of online casinos and games lets give them a proof they worry for nothing
provably fair scheme is born - hallelujah !
in simple words lets say i am the House hosting the game 'guess a card out of a full deck of 52'
me the House i am honest to death and i want to prove you that, before you risk your hard earned moneyZ
so i pick a card from my real deck after shuffling 233 times - i am poor to invest for LIVE cameras, damn!
my second best choice is this new thingy called provably-fair so here my clean implementation on that :
i am picking a card , lets say 'Ace of Spades' , then i browse any 'online SHA-256 calculator' found this one :
sha256into the input (source) text field i write
qw2ueFigaj56df today 03jan2021 time 07:20:14.46546 hand picked Ace of Spades as next result *2aZ3^U55TU%s@
*there are garbage characters in front and at the end. those must be random to keep your HOUSE safe against
attackers , if you sha256 only 'Ace of Spades' anyone can find your secret instantly
*in order to avoid including the hidden Return character better triple click to highlight the secret
here is the result i got / try it but wear a Covid mask perhaps j/k
c3619a92299a76dbe90eb8f5e7858705d1f4b354ffee04adf4feb8bd6b33895b
the magic goes further :
i am poor as i said so i have not a site to host my brilliant little game... NO PROBLEM !
so i invite my friend into a chat room, lets call myself as 'HouseOwner' and my friend as 'Costumer0001'
HouseOwner says : are we ready to play ?
Costumer0001 says : YAYYyyyyyy - i am more than ready and loaded ! shoot me !
HouseOwner says : next card i picked for you to bet hides under the following text :
HouseOwner says : c3619a92299a76dbe90eb8f5e7858705d1f4b354ffee04adf4feb8bd6b33895b
HouseOwner says : place your bets gentlemen !
Costumer0001 says : i bet 10 Marsian Dollars on Spades / pays 3.96 times /
HouseOwner says : here is my hidden secret :
HouseOwner says : qw2ueFigaj56df today 03jan2021 time 07:20:14.46546 hand picked Ace of Spades as next result *2aZ3^U55TU%s@
HouseOwner says : you WON 39.6 M$ -- your balance increased by 39.6-10=29.6 M$ - calculating next round... zzz zzz
.. a little later
ChatBot says : HouseOwner left the building ,OOPS !
Costumer0001 says : my bad , next time i will play this other game out of damn internet scams
RandomChat says : you mean that provably fair using carrier pigeons instead of chat rooms?
Costumer0001 says : internet is bad, yeah i think pigeons is more fair than this sit here
Fair game you say ! - to be continued i hope i teased you enough to stay tuned
