Functions

func CalcBlobFee

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

CalcBlobFee calculates the blobfee from the header's excess blob gas field.

func CalcExcessBlobGas

func CalcExcessBlobGas(config *params.ChainConfig, parent *types.Header, headTimestamp uint64) uint64

CalcExcessBlobGas calculates the excess blob gas after applying the set of blobs on top of the excess blob gas.

func LatestMaxBlobsPerBlock

func LatestMaxBlobsPerBlock(cfg *params.ChainConfig) int

LatestMaxBlobsPerBlock returns the latest max blobs per block defined by the configuration, regardless of the currently active fork.

func MaxBlobGasPerBlock

func MaxBlobGasPerBlock(cfg *params.ChainConfig, time uint64) uint64

MaxBlobsPerBlock returns the maximum blob gas that can be spent in a block at the given timestamp.

func MaxBlobsPerBlock

func MaxBlobsPerBlock(cfg *params.ChainConfig, time uint64) int

MaxBlobsPerBlock returns the max blobs per block for a block at the given timestamp.

func VerifyEIP4844Header

func VerifyEIP4844Header(config *params.ChainConfig, parent, header *types.Header) error

VerifyEIP4844Header verifies the presence of the excessBlobGas field and that if the current block contains no transactions, the excessBlobGas is updated accordingly.
