Satoshi Dice is a "blockchain-based betting game" operating since 2012. In 2014, off chain session based bets were also made available. Unlike traditional online gaming software, wagers with Satoshi Dice can be sent without access to the website nor running any client software. To play, a Bitcoin transaction is made to one of the static addresses operated by the service, each having differing payouts. The service determines if the wager wins or loses and sends a transaction in response with the payout to a winning bet or it returns a tiny fraction of the house's gain to a losing bet. As a result, the game spams the p2p network and blockchain with useless data. Satoshi Dice forces players to pay a transaction fee on each result so the spam will successfully flood both the p2p relay network and the blockchain. There has been the suggestion that the service might be also be used as a mixing service, as the composition of a wallet can be materially changed after running wagers through Satoshi Dice. Though this approach could change the makeup of the wallet, it does not sufficiently serve the mixing purpose as the coins returned in winning bets are tied to the coins from the wager transaction. The new session based game may send back a balance from unrelated addresses that are not tainted to the deposit address. However taint can still be applied at a later stage if change from the untainted withdrawal is later used together with the original deposit transaction. There is no reason to believe that Satoshi Nakamoto has anything to do with this attack, other than the service choosing to include the noun Satoshi in the brand. Satoshi Dice.com was announced on bitcointalk on April 24th, 2012, by its operator, Erik Voorhees. A user of this wiki claimed that it is currently operated by and licensed under Costa Rica-based Blockchain Limitada. It is unclear whether Mr. Voorhees controls Blockchain Limitada. A google search for "Blockchain Limitada" yields no hits.
