How are transaction fees calculated and charged?

Current blockchain applications have made waves in various industries from finance to healthcare. The unique security of blockchain and the advantages of decentralized transactions have also gradually expanded the scope of applications to other fields. However, in the use area Blockchain-related transactions often incur certain exchange fees. What exactly are the transaction fees charged by the blockchain? Many people don’t understand that blockchain transaction fees are fees paid to network miners or validating nodes when cryptocurrency transactions are made. These fees are used to incentivize network participants to verify and package transactions and add them to blocks. In the chain, the editor will tell you in detail below.

#What are the transaction fees charged by the blockchain?

Blockchain transaction fees are fees paid to network miners or validating nodes to ensure that transactions are effectively added to the public chain of records. When performing blockchain operations, paying transaction fees is required.

These operations may be as simple as sending a cryptocurrency or digital asset to the recipient, or as complex as utilizing a decentralized application (dapp) to perform actions such as borrowing a certain amount. Blockchain nodes are responsible for performing these activities on behalf of others, and blockchain transaction fees serve as their compensation.

The blockchain’s native crypto-assets are used as the medium of exchange for most transaction fees. For example, fees associated with Bitcoin transactions are paid in Bitcoin, while fees associated with Ethereum transactions are paid in Ethereum. Generally speaking, simple transactions charge lower transaction fees, while relatively more complex transactions charge higher transaction fees.

How are blockchain transaction fees calculated?

Users who wish to include transactions in the next blockchain block need to pay a fee. The economic motivation of nodes is transaction fees, and nodes with high fees are preferred.

The cost is usually expressed in terms of a specific rate per unit of data, such as satoshis per byte on the Bitcoin blockchain. Transaction fees increase proportionally to the square root of the transaction size in bytes. Additionally, if the network is congested, users may need to pay higher fees to ensure transactions are completed in a timely manner.

Blockchain transaction fees are set according to user needs and network busyness. The minimum fees for different blockchains may be affected by network congestion, market demand, transaction type and other factors.

Generally, blockchains that use the Proof of Stake (PoS) consensus mechanism usually have lower transaction fees than blockchains that use the Proof of Work (PoW) consensus mechanism. Some examples of blockchains using low transaction fees include Binance Smart Chain (BSC), Solana, and Polygon.
