provablyfair
sample provably fair algorithm for gambling
read about it here: [soon]
all hashes are SHA-512
you can use seededprovablyfair.js for generating hashes and results
there is also a sample provablyfairhost.js and provablyfairclient.js included here
client would run in the browser and host would run on the server
functions:
generateRandomSeed(callback);
generate a random hash to be used as the host hash or the first game hash for a chain of games
callback is the hash
generateChainSeeds(firstGameSeed, amountOfGames, callback);
generate a chain of game hashes
callback is a json object, you can access the hashes with callbackData[numberOfGame]['gameSeed']
also callbackData['total'] gives you the amount of games so you can loop through them easily
generateResult(hostSeed, gameSeed, callback);
generate the result of a game, combining the host seed and the game seed
callback is a double digit number
