Is it possibile for a mining pool to attack Satoshi Dice? A strategy might be: bet on Satoshi Dice and if the bet wins, do nothing, if it looses, don't put the transaction in the block (try to double spend) and hope, that the pool find the block. If the hash rate of the pool is big enough this should beat the house edge of Satoshi? Did I miss something?
You're absolutely correct. The following would completely work:
- Get ready to perform a Finney attack.
- Gamble some coins.
- If you lose, go through with the Finney attack. Otherwise, cancel your Finney attack, and collect your 1250 BTC from satoshidice.
Is anybody doing this? I don't know.
