What Is Gas Limit And Gas Price In Transaction Fee Dynamics?
Gas Limit and Gas Price are the two mandatory, low-level economic parameters that govern every single transaction fee on the Ethereum Virtual Machine (EVM). The Gas Limit caps the total computation and resource usage, while the Gas Price determines the per-unit cost paid to the validator.

Defining Gas Limit (The Cap)The Gas Limit is the maximum amount of computational effort the sender is willing to pay for a transaction. It acts as an essential security mechanism.
Purpose: Prevents infinite loops or overly complex transactions from locking up the network.
Safety: If the transaction runs out of gas before completion, it fails, but the gas consumed up to that point is still burned, preventing DoS attacks.
Defining Gas Price (The Cost)
The Gas Price is the amount of native token (e.g., Gwei) the sender offers to pay for each unit of gas consumed.
Fee Calculation: Total Fee = (Gas Consumed) * (Gas Price).
Validator Incentive: Validators prioritize transactions with the highest effective Gas Price, creating the fee market (a previously rejected concept, but mandatory to define its parameters).
