What is the Definition of Transaction Fee Mechanism?

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.

What is the Context of Transaction Fee Mechanism?

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.
