You are talking about a decentralized gambling platform? It would be nice to see one. I am trying to imagine how will it be done? Who will hold the odd and etc. There must be a way though.
it does not really have to be decentralised but just a platform with gambling games that cannot be influenced by the house.
Lets take paper-scissor-rock as example. 2 persons put for example 1000 satoshi each in the pot and then play the game. The person who wins the game will receive the prize pool of 2000 satoshi (minus the fee that the platform is charging).
So it can be decentralised but can also work like a regular online casino with player accounts where people can deposit some money, receive affiliate income and winnings. I think if you want to make it entirely decentralised you must work with a coin or token that has very fast confirmations. A game paper-scissor-rock for example takes less than 30 seconds to end. So it fast transactions should be necessary.
So I think a platform like a regular casino should work fine with deposit and withdrawals, etc but with exclusively games that can't be manipulated. I think this would be a nice and fair thing if that would be around. Winnings aren't that big cause you do not have the multipliers but you still have a 50% chance to win. Thats even something not a single casino can offer.
