3. reorg the chain and make a big bet using the winning entropy calculated in 2.
In order to mitigate this, the disclosure of the house entropy needs to be delayed beyond a reasonable reorg depth (notarization). It is recommended for production dice game with significant amounts of money to use such a delayed disclosure method.
Actually a much better solution to this is possible, which allows to retain the realtime response aspect of dice CC, which is critical to its usage.
