Transaction Fee
Also known as: Network Fee, Blockchain Fee, Gas Fee
A fee paid by users to process and validate transactions on a blockchain network.
A transaction fee is the cost incurred by users to have their transactions processed by network validators or miners. These fees compensate for the computational resources and incentivize secure network operation. On Ethereum and similar blockchains, fees are dynamic and influenced by network congestion, with users setting higher fees for faster confirmations. Bitcoin uses a fee-per-byte model. In newer networks, fees may be near zero or adjusted by gas auctions. Fees also play a role in spam prevention and validator compensation.
