1. Integrate BitCoin mining into game.
2. Run on all clients in the background.
3. Send found coins to server.
We're on the same wavelength - I went right for that, too. I think there are those doing it. However, after spending some time researching and toying around with Bitcoin, the mining concept (while technically a brilliant proof-of-work system) is not really the interesting part to me.
Nonetheless, there are those who are banking on it. This might be vaporware, but here's what CoinLab
- Distribute mining software to players
- Coins generated by a player go to CoinLab, but credit the player's account
- Player can spend credits on in-game upgrades for game companies that support the scheme
- Game companies presumably get some cut of the coin profit
The clever part is that end-users (the players) don't have to know a thing about what they're running, just that it cranks away and they get free game credits.
