Unlike in traditional environments, e-gambling players must make a beforehand payment to start a game. Most online casinos currently solve this problem using prepayment systems where the on-line casino has absolute control over all the transactions among the players. However, this solution poses a great number of problems because of the necessary trust relation between players and the on-line casino managers. To reduce this strong trust relationship with the on-line casino, we propose in this paper the use of a reliable digital chips system, which provides auditing facilities, and can be trusted by external parties. Digital chips, just like physical ones, will be used for players instead of legal course money. A set of cryptographic protocols will protect the different actions that players can perform using these digital chips.
