The Blockchain transaction fee is a charge that users pay when they conduct cryptocurrency transactions. The fee is paid for the network to execute the transaction. To ensure that your cryptocurrency transactions arrive on time, users must pay the blockchain charge.
Blockchain transaction fees are one of the most important ways for speeding up crypto transactions, which are often slowed by a blockchain network’s high congestion. The lower your transaction’s priority in the blockchain network, the lesser will be the blockchain charge. In blockchain networks, transaction fees serve two functions. They reward miners who assist in the confirmation of transactions and help protect the network against spam attacks.
Network congestion, transaction confirmation cycles (impacted by liquidity providers), and transaction size are all factors that impact blockchain fees (as measured in kilobytes; affected when converting crypto from multiple inputs such as faucet earnings or other micro-transactions).
<h2>Why is the Blockchain Transaction Fee required?</h2>
Since their introduction, Blockchain Transaction Fees have been an integral part of most blockchain systems. You’ve probably come across the fees while sending, depositing, or withdrawing cryptocurrency. Blockchain Transaction Fees are used for the majority of cryptocurrencies for two purposes.
<ul>
<li style="font-weight: 400;" aria-level="1">First, Blockchain Transaction Fees minimize the amount of spam that circulates on the network. Large-scale spam attacks become more costly and challenging to execute as a result.</li>
<li style="font-weight: 400;" aria-level="1">Second, Blockchain Transaction Fees reward users who assist in the verification and validation of transactions. It can be viewed as a form of incentive for supporting the network.</li>
</ul>
<h3>Reasons behind high Blockchain Transaction Fees</h3>
Blockchain Transaction Fees are relatively low for most blockchain systems, but they can become very costly depending on network traffic. Your transaction’s priority of being added to the next block is determined by the number of fees you want to pay as a customer. The faster the confirmation procedure, the higher the blockchain transaction fee charged. Some other reasons could be-
<ul>
<li style="font-weight: 400;" aria-level="1">The blockchain network could be busy or overburdened. During unexpected blockchain rate spikes and significant world events, the fee usually rises.</li>
<li style="font-weight: 400;" aria-level="1"> If your account has many small deposits, your transaction will be more significant because it will have many inputs, and the blockchain transaction fee rises in proportion to the transaction size.</li>
</ul>
<h3>Tips to reduce Blockchain Transaction Fees</h3>
<ul>
<li style="font-weight: 400;" aria-level="1">Look for a less congested timespan on the blockchain. Businesses are usually closed on weekends, for instance, and fewer sales are made overall. This allows transactions to clear a little faster. Alternatively, submit your transaction for a lower price and then wait for it to clear. </li>
<li style="font-weight: 400;" aria-level="1">Keep track of the network’s average blockchain fee. You should wait until the average fee amount decreases if your move is not time-sensitive.</li>
</ul>
<h2>Blockchain Transaction Fees For Bitcoin</h2>
Bitcoin established the standard for Blockchain Transaction Fees which is now used by many cryptocurrencies today. <a href="http://delta.exchange/glossary/satoshi-nakamoto">Satoshi Nakamoto</a> realized that Blockchain Transaction Fees could help protect the network from large-scale spam attacks while also rewarding good conduct.
As part of the procedure of verifying transactions to a new block, Bitcoin miners are paid transaction fees. Miners would naturally prefer transactions with higher Blockchain Transaction Fees that users decided to pay while sending Bitcoin to another wallet.
Cybercriminals who want to shut down the network will have to pay a charge for each transaction. Miners will most probably ignore their transactions if they place the fee too low. They incur a high economic cost if they set them at a suitable stage. As a result, Blockchain Transaction Fees serve as a primary but powerful spam filter. 
<h3>Calculation</h3>
Some cryptocurrency wallets on the Bitcoin network enable users to set transaction fees manually. It is also possible to submit Bitcoin with no fees, but such transactions would most probably be ignored by miners, meaning the transaction would not be validated by miners. Unlike popular belief, Bitcoin fees are determined by the transaction size rather than the amount sent (in bytes).
As network traffic is high and there is a lot of demand for Bitcoin, the blockchain transaction fee required for quick confirmation increases as more Bitcoin users want to do the same thing. This can happen during times of high market volatility. A block may only contain a certain number of transactions, and each block is limited to 1MB (i.e., block size). Miners work as quickly as possible to connect these blocks to the blockchain, but there is a restriction on how far they will go. The scalability of cryptocurrency networks is an essential factor to consider when determining network fees. The issue is being addressed by blockchain developers continuously.
<h2>Blockchain Transaction Fees For Ethereum</h2>
In contrast to Bitcoin, Ethereum transaction fees function differently. The fee needed to complete an Ethereum transaction is referred to as gas. Gas has a variable price calculated in the network’s native token, ether (ETH). Although the amount of gas required for a particular transaction will remain constant, gas prices may rise or fall. The cost of gas is directly proportional to network traffic.
<h3>Calculation</h3>
The fee required to perform a transaction on the Ethereum network can be calculated in several ways. The network is set up in a manner that any charge can be set arbitrarily. As a result, a sender might theoretically choose any amount as the transaction fee they’re prepared to pay, no matter how small. 
There are hundreds of online gas calculators that can help Ethereum investors figure out how much gas their transaction would need. Even so, transaction fees on the Ethereum network can be calculated without using an online calculator. A potential sender should know how much gas each Ethereum operation requires, as well as a clear understanding of gas prices’ average market rate.
<h2>Conclusion</h2>
Blockchain Transaction Fees are an inevitable part of the crypto world. However, to save money on transaction fees, users should research and find out the best exchange platforms with minimal transaction fees and other charges.

Blockchain transaction fees are one of the most important ways for speeding up crypto transactions, which are often slowed by a blockchain’s high congestion.
