Decentralized Fairplay power for competitive real-time games Demo : Choose a color, team up with your friends and battle for cube domination.
When hundreds of thousands of players come to swarm a game server, small yet critical data corruption can occur. Very often, many players think they were the first to execute an action and the server usually settles the matter the easy way sometimes changing the outcome of the game. Furthermore, eSport tournament's growing prizes can push some to cross the fairness line, and penalties come often late.
With Hedera Hashgraph's powerful consensus protocol and precise timestamped record or transactions, any game producer can push a set of rules to be observed and let their server trust the wise arbitrage of Coloreen. 3 different API's (Producer Campaign rules editor, Game Server Arbitrage, and Unified Gamer ID Reputation Wall) ensure Game popularity stays higher over time and fairness incentivization.
