<p>Transaction fee is a method by which anyone who creates a transaction incentivizes the miners to include that transaction in the block that the miner will mine. Bitcoin blocks can have a maximum 4MB of block weight, which means there are only certain transactions that can be included in the block that is being mined. So you include a fee so that miner picks your transaction over others to include in the block. Transaction fees also serve another purpose of preventing DoS attacks. If there were no fees, people in order to spam the network would send between between addresses they control so as to deny the service to legitimate people. Transaction fees ensure that there is a cost associated for launching such attacks.</p>

<p>To be more thorough, you do not send a transaction fee to a particular address, but it is the difference between the input and output amounts. So consider a transaction that consumes 1BTC and sends 0.8BTC to one address and 0.15 BTC to another address, then the transaction fee is 0.05BTC. When the miner creates the coinbase transaction for the block he is mining, he will pay out the block reward (12.5 BTC currently) and sum of all the fees of the transactions that are included in the block to the pool participants.</p>

# Mining Pools Transactions Fee

(Asked by: username_0 on 2019-05-22)

I am learning about mining pools and trying to understand their reward structure and transactions fees.

Looking at the two largest pools, Antpool & BTC.com, as far as I understand AntPool uses PPS and BTC.com FPPS.

The main difference i guess is that in FPPS also the transaction fees are incorporated in the reward structure.

First of all, what exactly is the transaction fee? The fee of finding a block? The fee of transferring the btc reward to another account?

and how can the transaction fee be incorporated in the reward structure as in FPPS?
