Transaction fees are always processed and received by the miner. When a new hash is used to generate a successful bitcoin block, all the transactions information is included in the block together with transaction fees which are collected by the miner. The miner is free to assign bitcoin fees as he pleases.
The person making a bitcoin transaction has a voluntary will because he can include any costs to the transactions or not at all. However, no new bitcoin miner necessarily needs to accept transactions and create a new block when created. Therefore, the transaction fees is an incentive levied on the bitcoin user to ensure that a transaction is included in the next generated block.
It is overseen that the collective transaction fees out of cumulative effect allow new block creators to make earn more coins than those mined from new bitcoins that are created from new blocks over time. This is an incentive levied to allow for the trial to create blocks even when the newly created blocks amount to zero in future.
In the past, the sender used to pay the full amount of bitcoin network transactions. The fee was deducted from the received amount. The recipient often considered it as an incomplete transaction.
Network security is one of the most important services miners provide. This big network of hash rates is covered by miners to keep bitcoins safe from hackers and bad actors. These miners need some little cash for this purpose to pay for their hardware costs, electricity and other bills. ASIC mining hardware keeps the bitcoins secure through the working proof. Therefore, these miners get paid through bitcoin’s block combination transaction fees and rewards.
Block rewards is a significant income that provides the miners an income. They start at 50 bitcoins per block the previous number is 20 bitcoins per block. It dropped to 12.5 bitcoins per block this year.
