Transaction Fee Mechanism

Definition ∞ A Transaction Fee Mechanism dictates how fees are calculated and allocated for processing transactions on a blockchain. It governs the interaction between users seeking to execute transactions and the network validators who confirm them. Effective mechanisms balance network security, throughput, and fairness for all participants.
Context ∞ The evolution and optimization of Transaction Fee Mechanisms are a continuous area of development and debate within blockchain technology. Current conversations often center on the efficiency of EIP-1559 on Ethereum, the impact of fee markets on network usability during periods of high demand, and the design of alternative fee structures for layer-2 solutions. The stability and predictability of these mechanisms are key considerations for user adoption.
