Abstract: Gambling has been one of the traits of human nature since the beginning of time and roulette in particular is one of the most popular games today. Blockchain technology for almost ten years now has revolutionized many aspects of our lives introducing cryptocurrencies as well as other innovative constructions such as smart contracts. The combination of the two has been examined and various constructions have been proposed but all of them are either centralized or require trust at some level, require fees and do not offer choices with respect to gambling to players. In our protocol we address these problems and solve them. We show that by generating a sidechain to any blockchain everyone can create his own game. Also, by using a signature scheme alongside the ElGamal encryption scheme and the hash function SHA256 we prove the randomness of the result in the random oracle model. We include as well a recovery scheme for penalizing players who deviate from the protocol and an algorithm to ensure the integrity of the players' assets. To the best of our knowledge this is the first fully-decentralized, zero-trust, zero-fee cryptographic protocol which executes a game of roulette, providing options with respect to gambling.
