Function calc_next_block_base_fee

pub fn calc_next_block_base_fee(
    gas_used: u64,
    gas_limit: u64,
    base_fee: u64,
    base_fee_params: BaseFeeParams,
) -> u64

Calculate the base fee for the next block based on the EIP-1559 specification.

This function calculates the base fee for the next block according to the rules defined in the EIP-1559. EIP-1559 introduces a new transaction pricing mechanism that includes a fixed-per-block network fee that is burned and dynamically adjusts block sizes to handles transient congestion.

For each block, the base fee per gas is determined by the gas used in the parent block and the target gas (the block gas limit divided by the elasticity multiplier). The algorithm increases the base fee when blocks are congested and decreases it when they are under the target gas usage. The base fee per gas is always burned.

Parameters:

• gas_used: The gas used in the current block.
• gas_limit: The gas limit of the current block.
• base_fee: The current base fee per gas.
• base_fee_params: Base fee parameters such as elasticity multiplier and max change denominator.

Returns: The calculated base fee for the next block as a u64.
