Functions ¶
func CalcBaseFee ¶
func CalcBaseFee(config *ethparams.ChainConfig, parent *Header) *big.Int
CalcBaseFee calculates the basefee of the header.
func MakeGlobalEthash ¶ added in v1.0.0
func MakeGlobalEthash(dir string)
func VerifyEip1559Header ¶
func VerifyEip1559Header(config *ethparams.ChainConfig, parent, header *Header) error

Types ¶
type Config ¶ added in v1.0.0
type Config struct { CacheDir string CachesInMem int CachesOnDisk int CachesLockMmap bool DatasetDir string DatasetsInMem int DatasetsOnDisk int DatasetsLockMmap bool PowMode Mode Log log.Logger `toml:"-"` }
Config are the configuration parameters of the ethash.
type Ethash ¶ added in v1.0.0
type Ethash struct {
// contains filtered or unexported fields
}
Ethash is a consensus engine based on proof-of-work implementing the ethash algorithm.
