What process takes place behind 100 confirmations counting down to zero when earnings become confirmed. I joined a different pool for a couple of days but there was no such thing there.
I'm back to slush for the fact that it is so simple... and I've gotten a lot of support here.
The process is just waiting for other blocks to be generated, to make sure the block found by the pool is part of the (longest) valid chain and not an orphaned fork.
The pool operator has to decide how much risk to take, some pay right away and hope its valid, some count down without displaying (and have the earnings show as unconfirmed reward, too).
