“A decentralized ‘smart contract’-based platform pricing provably fair fixed odds bets at the minimum possible edge, returning profits to token holders through deflation.” EdgeFund is an entirely decentralized bankroll of blockchain tokens, accessible solely via betting functions written in smart contract code. It allows fixed odds bets to be accepted and paid out without the need for any trusted central authority. The bankroll can be used by game operators who want to offer large payouts without risking their own funds. The smart contract code protects its bankroll of tokens from bankruptcy by dynamically calculating the lowest possible platform edge it can charge for each bet based on the Kelly Criterion. The smart contract code is publicly viewable and provably fair, with the outcome of bets determined by decentralized random number generation. Game operators have freedom over the bet size, payout odds and total house edge, profiting on every bet from the difference between the total house edge and the platform edge. This profit (along with any user winnings) is returned to the game operator by the smart contract after every bet, regardless of the bet outcome. The platform enables any number of fixed odds betting games to be built on top of it. Native platform tokens become more scarce over time on average due to accumulation within the smart contract bankroll, in effect distributing profits to token holders through deflation.
