<p>The number of mining machines or nodes has nothing to do with this. You could do this with one machine and one node.

<p>Can I become a Bitcoin miner by setting up multiple nodes to give higher priority to my own transactions to process them for less fee or for no fee? </p>

<p>My understanding is that a confirmation is when a miner includes your transaction in a block he calculates and submits. So can you setup like six or more mining machines which gives higher priority to your own transaction if you know the transactions output addresses already? Or is it just an automatic process which you can't change?</p>

<p>If it's possible then how exactly I can achieve this?</p>
