transacton fee belongs to pool operators

[PRCman]

1  transacton fee(if there is) belongs to pool operators( acturally the block creater, most are pool operators) is that true?
2  how can pool operators determine labors who just submit share hash done no result found , without any calculation?

Transaction fees are claimed the same way as the BTC rewards for block solving.

Couldn't you rephrase this question please, I can't wrap my mind around it.

"How can pool operators identify someone who submits a false 'share complete' message to the pool without actually performing any work to calculate a solution?"

The solution is always verified. One double block hash is quick. Performing a metric ton of them to find one that fits the solution is long.

In most pools, yes, the pool operator keeps the transaction fees. There is at least one small pool that distributes the transaction fees to the miners.

There is a difference between a Share and a GetWork. You don't "complete" working on a Share, you find a share (a hash of the block header that meets difficulty >= 1) within the space of the GetWork. Most of the time, you don't even bother to finish looking through the entirety of the GetWork solution space, you just request a new GetWork every once in a while.

Pools count the number of solutions of difficulty >= 1 that you found. That is proof that you have been doing work. One of those solutions might also be a full solution that exceeds the current real difficulty.

And the pool does confirm that all shares that are submitted are valid.

You can see the fees at blockexplorer.com by clicking on the finished blocks.

I looked at the last group for the fees.
.01
.1
0
.02
.03
So for the last 5 blocks all combined the fees are .16 btc  Not really much at all.  The pool operators are not 'cashing in' on these fees by keeping them yet.
