Where can I get information about private blockchains? I'm designing a decentralized multiplayer game with potentially dozens of players. Each player would need to access a DAPP (on the public chain) to exchange ether for game tokens, and, when leaving the game, access the same DAPP to exchange tokens back to ether.
The game, however, would generate a huge number of transactions, and the cost of gas would be prohibitive. Would it be feasible to use a private blockchain within the game? If the players used the Mist browser, would that platform be able to mine the private chain? Would a Mist instance be able to access both the public and private chains?
Or should the game be a web-based app using ethereum-js accessing geth?
