A Blockchain is a peer-to-peer network where every user has the same rights and privileges. All users can access the network and its contents without special permission.
This structure makes Blockchain a decentralized system, which can have a major impact on many industries that rely on centralized networks. There are costs associated with using a Blockchain, and those costs manifest in transaction fees.
But what exactly do these transaction fees mean, and why do they exist? If you have ever used an online payment service like PayPal, you will be aware of the small transaction fee that is usually associated with these transactions.
This fee is a nominal amount that is charged both by the payment processor and the receiver of funds to cover their operating costs and other expenses related to the transaction.
However, in the case of Blockchain transactions, similar costs cannot be recovered directly from users due to their decentralized nature. Instead, the miners who verify the transactions on the network charge a nominal fee, which they get as an incentive for providing their computing power for mining blocks.
These mining fees are separate from mining difficulty, which is another cost that miners incur when verifying transactions and unlocking new coins as an incentive to continue mining.
This article will explain what transaction fees are in Blockchain technology and why they exist.
What are transaction fees in Blockchain?
A Blockchain transaction fee is an amount that a user has to pay to the miners to have their transaction validated on the Blockchain. Any request made to the Blockchain network that doesn’t result in a mining reward will also be charged a transaction fee.
These fees are usually denominated in the token that serves as the Blockchain network’s native currency. However, for transparency purposes, many Blockchain networks let you set the fees you want to pay for your transaction.
A Blockchain transaction fee is a small amount that is charged to the users who send transactions to the Blockchain network. These fees help in the mining process and reward the miners for providing their computing power for the operations.
How do transaction fees in Blockchain work?
When a user sends transactions to the Blockchain network, it is broadcasted to all the nodes in the Blockchain network for validation. If the majority of the nodes accept the transaction, it will be added to the Blockchain ledger as a new block.
Since the miners receive the transaction fees (mined tokens) as an incentive in their wallet, they verify the transaction as quickly as possible.
In simple terms, the transaction fee is a nominal amount that the user has to pay to the miners to have their transaction verified and added to the Blockchain ledger. Each Blockchain network has a maximum limit on the transaction fee users can set for their transactions.
The transaction fee can be set at a nominal amount, or it can be set at zero. If you set your transaction fee to zero, it means that you are willing to wait longer for the validation of your transaction by the miners because they won’t receive any incentives for verifying your transaction.
Why do transaction fees in Blockchain exist?
The transaction fees are charged to the users who want to send their transactions to the Blockchain network. These fees exist for various reasons, but the main reason is to reward the miners for validating the transactions.
When users send a transaction to the Blockchain network, it is verified by the miners, who use their computing power to unlock new blocks in the Blockchain network.
The miners also verify the transactions in the Blockchain and add them to the ledger. In this process, the miners receive the transaction fees in the form of the native cryptocurrencies of the Blockchain network. If there are no transaction fees, the miners will lose their incentive to validate the transactions because they won’t get anything in return.
Transaction fees also help in avoiding spam transactions sent to the Blockchain network. If someone wants to spam the Blockchain network, they will send a huge number of transactions to the network to disrupt the operations.
However, if there are transaction fees, the spammer will have to pay a nominal amount to verify their transactions. This will reduce the number of spam transactions sent to the Blockchain network and help reduce the number of spam attacks.
Example of transaction fees in Blockchain
Let’s assume that you are sending 1 Ether from your wallet to another person. In the case of Bitcoin, the transaction fee will be about 10-15 Satoshis or 0.0001 BTC per 1 transaction.
In order to get your 1 Ether sent, you will have to pay about 0.001-0.002 ETH in transaction fees. If you want to send 100 Ether in one go, then it will cost you 0.1-0.2 ETH in transaction fees.
If you want to send 1,000 Ether, you will have to pay 1-2 Ether in transaction fees. Each Blockchain network has a different transaction fee structure, and it is important to understand the transaction fee structure of your preferred Blockchain network.
Why understanding transaction fees in Blockchain is important
When you send a transaction to the Blockchain network, you can set the transaction fees to process the transaction faster. However, if you set the transaction fees to low, the miners won’t have any incentives to verify your transaction.
This can result in your transaction taking longer to get verified and added to the Blockchain network. Similarly, if you set the transaction fees too high, it can result in your transaction getting verified quickly, but it will cost you a significant amount in transaction fees.
You should keep track of the transaction fees on different Blockchain networks and set the transaction fees accordingly to send your transactions quickly.
Understanding how transaction fees in Blockchain work are important because you get to know how much you are charged per transaction made and how to minimize these fees.
Making every effort to minimize these fees will help reduce the amount of money you spend each month—and that’s always a good thing.
What is the purpose of transaction fees in Blockchain?
The purpose of transaction fees is explained better below;
- Supporting Transaction Processing
One of the main reasons for charging transaction fees is to cover the operating costs for processing and validating the transactions. Users sending funds via Blockchain technology do not incur any processing fee associated with centralized payment services like PayPal or Venmo.
However, the decentralized nature of Blockchain technology means that those services cannot be recovered from the users directly. This means that the miners on the Blockchain network will have to cover these costs with their transaction fees. Specifically, when miners verify a transaction, they add it to the Blockchain network.
They also confirm that the sender has the funds and that they are not trying to double-spend. While this might seem like a trivial thing, it is actually a costly process when it comes to computing power.
The miners must use a huge amount of computing power to solve complex equations while validating the transactions. This is why transaction fees are charged on a per-transaction basis to recover a portion of the costs associated with supporting the transaction processing.
- Paying Those Validating The Transaction
As we mentioned above, the transaction fees are used to reward miners for validating the transaction. However, the miners are not the only ones rewarded for their efforts. The users who send funds are also charged a nominal fee for their contribution to the transaction.
You might be wondering if the sender is also rewarded for supporting the transaction, then who exactly is paying the transaction fee? The answer is the entire Blockchain network.
In simpler terms, the miners get the transaction fee from both the sender and the receiver of funds. This ensures that both parties are rewarded for sending funds, and the miners get the incentive to validate the transaction.
The amount of transaction fee charged depends on the size of the transaction. For example, if you send $50 to someone, you will be charged a small fee due to the small size of the transaction. However, if you send $50,000, you might be charged a higher transaction fee because of the large size of the transaction.
- Eliminating Spam Transactions
In a decentralized network like Blockchain, every transaction needs to be verified by the miners before they can be added to the Blockchain. This means that transactions are not confirmed instantly; instead, they get added to the Blockchain over time.
When the transaction volume is high, it might take a few minutes or even hours to confirm the transactions. Most Blockchain networks have transaction limits to prevent malicious activities and denial-of-service (DoS) attacks.
This means that if you send funds larger than the defined transaction limit, your transaction will be rejected. This is done to prevent DoS attacks and malicious activities such as network spam.
However, genuine transactions will also be rejected if the transaction limit is too low. This is where the transaction fee can significantly impact the transaction time. If a fee is set too high, it becomes costly to send funds. This can slow down the transaction process as the users will have to wait for their funds due to high fees.
How are transaction fees calculated?
The transaction fees charged by the Blockchain networks are in the form of cryptocurrencies. To calculate the transaction fees, you will have to find out the mining difficulty of the Blockchain network and the mining reward for the last block.
The mining difficulty is related to the number of miners who are mining on the Blockchain network. The mining difficulty of the Blockchain network is usually high, and it decreases when the mining difficulty of the Blockchain network is low.
The mining reward is related to the number of rewards the miners will receive for unlocking the next block in the Blockchain network. The transaction fee is calculated based on the mining difficulty and mining reward.
For example, let’s say that the mining difficulty of a Blockchain network is 10, and the mining reward per block is 1. The transaction fee will be 10% of the mining reward per block, which will be 1. The transaction fee can be calculated differently depending on the Blockchain network.
Types of transaction fees
There are three types of Transaction fees in the Blockchain network. They include; exchange fees, network fees, and wallet fees.
Exchange fees
Exchanges are websites and apps where users can buy and sell cryptocurrencies. These exchanges are centralized systems that are controlled by a single entity. Although these exchanges are a convenient way to trade and sell digital tokens, you will have to pay a small transaction fee to the exchange.
This transaction fee is charged per transaction basis and can vary depending on the volume of transactions and the size of funds being exchanged. The transaction fee can be paid through the exchange’s native token or other popular cryptocurrencies like Bitcoin and Ether.
Network fees
Network fees are the transaction fees charged by the underlying Blockchain network. These fees are charged for adding a new transaction to the Blockchain network. However, the network fee amount is not fixed and is autonomously determined by the Blockchain network.
Sometimes, Blockchain networks might impose a “gas limit” for a specific transaction. This means that the transaction will only be confirmed if the sender pays the appropriate network fee. These network fees can be very high during periods of high network usage and can significantly impact the transaction time.
Wallet fees
Wallet fees are the transaction fees charged by the wallet service provider. Some well-known wallet providers are Coinbase, Binance, Bittrex, etc. A wallet is an online service where you can store your cryptocurrencies. These wallets charge a nominal fee on a per-transaction basis.
Conclusion
You typically pay a transaction fee when you send money to a friend. Such transaction fees are typical of any financial system, including digital money like cryptocurrency.
Transaction fees have always been an essential part of the financial and investment services sectors, and Blockchain is no exception.
This is because miners use the funds collected from these fees on the Blockchain network to help incentivize them for their services.
