I think I would like to know WHO exactly gets the transaction fee?
The fee goes to the miner or mining pool which finds the block your transaction is in. In the end, when block reward is void the transaction fee will be what keeps miners mining.
Does that mean a miner (or pool) who discovers a block will get a % every time that some of that block is transacted, or is this a 1 time transaction as it leaves the pool or miner?
Thanks for the reply.
The sender can voluntarily include a fee in addition to the total being sent. This fee acts as an incentive to the mining community to include the transaction in the blockchain. When a miner (or pool) chooses to include transactions in a block that they're working on, and they successfully solve that block, that miner (or pool) gets all the transaction fees from all the included transactions. Once a transaction is successfully included in a block in the blockchain, it cannot be included in any future blocks.
