BaseFee

BaseFee

BaseFee is the set price per unit of gas (measured in attoFIL/gas unit) to be burned (sent to an unrecoverable address) for every message execution.

The value of the BaseFee is dynamic and adjusts according to current network congestion parameters. For example, when the network exceeds 5B gas limit usage, the BaseFee increases and the opposite happens when gas limit usage falls below 5B. The BaseFee applied to each block should be included in the block itself. It should be possible to get the value of the current BaseFee from the head of the chain. The BaseFee applies per unit of GasUsed and therefore, the total amount of gas burned for a message is BaseFee * GasUsed.

Note that the BaseFee is incurred for every message, but its value is the same for all messages in the same block.
