IsHomestead returns whether num is either equal to the homestead block or greater.

func (*ChainConfig) IsIstanbul added in v1.9.51 

func (c *ChainConfig) IsIstanbul(num *big.Int) bool

func (*ChainConfig) IsPetersburg added in v1.0.0 

func (c *ChainConfig) IsPetersburg(num *big.Int) bool

func (c *ChainConfig) Rules(num *big.Int) Rules

Rules ensures c's ChainID is not nil.

func (*ChainConfig) String 

func (c *ChainConfig) String() string

	Threshold uint64           `json:"threshold"`
}

type CliqueConfig 

type CliqueConfig struct {
	Period uint64 `json:"period"` // Number of seconds between blocks to enforce

CliqueConfig is the consensus engine configs for proof-of-authority based sealing.

func (*CliqueConfig) String 

func (c *CliqueConfig) String() string

String implements the stringer interface, returning the consensus engine details.

type ConfigCompatError 

type ConfigCompatError struct {
	What string
	// block numbers of the stored and new configurations
	StoredConfig, NewConfig *big.Int
	// the block number to which the local chain must be rewound to correct the error
	RewindTo uint64
}

ConfigCompatError is raised if the locally-stored blockchain is initialised with a ChainConfig that would alter the past.

func (*ConfigCompatError) Error 

func (err *ConfigCompatError) Error() string

type CuckooConfig added in v1.0.0 

type CuckooConfig struct{}

func (*CuckooConfig) String added in v1.0.0

	Calls       uint64
	Suicide     uint64

	ExpByte uint64

	// CreateBySuicide occurs when the
	// refunded account is one that does
	// not exist. This logic is similar
	// to call. May be left nil. Nil means
	// not charged.
	CreateBySuicide uint64
}

GasTable organizes gas prices for different cortex phases.

type Rules 

type Rules struct {
	ChainID                                                 *big.Int
