Functions

func CalcBaseFee

func CalcBaseFee(config *params.ChainConfig, parent *types.Header, timestamp uint64) ([]byte, *big.Int, error)

CalcBaseFee takes the previous header and the timestamp of its child block and calculates the expected base fee as well as the encoding of the past pricing information for the child block. CalcBaseFee should only be called if [timestamp] >= [config.ApricotPhase3Timestamp]

func EstimateNextBaseFee

func EstimateNextBaseFee(config *params.ChainConfig, parent *types.Header, timestamp uint64) ([]byte, *big.Int, error)

EstiamteNextBaseFee attempts to estimate the next base fee based on a block with [parent] being built at [timestamp]. If [timestamp] is less than the timestamp of [parent], then it uses the same timestamp as parent. Warning: This function should only be used in estimation and should not be used when calculating the canonical base fee for a subsequent block.

func MinRequiredTip

func MinRequiredTip(config *params.ChainConfig, header *types.Header) (*big.Int, error)

MinRequiredTip is the estimated minimum tip a transaction would have needed to pay to be included in a given block (assuming it paid a tip proportional to its gas usage). In reality, there is no minimum tip that is enforced by the consensus engine and high tip paying transactions can subsidize the inclusion of low tip paying transactions. The only correctness check performed is that the sum of all tips is >= the required block fee.

This function will return nil for all return values prior to Apricot Phase 4.
