my question may sound stupid, but how do you know when you have found a block ?
After opening up your wallet or typing
refresh, you will get three transactions: one for 0.5 BMR, one for 7 BMR and onr for 10 BMR. Yes, there will be "transaction", not "mining". Of course, it could someone sending you in a row 0.5, 7 then 10
There is presently no way I am aware of to have a history of found block. If you found a block yesterday, closed the wallet in the evening and open it up today, closed it again and reopened it, you have no way to know you found a block except by looking at your balance (provided you remember of much you had).
