GasTable returns the gas table corresponding to the current phase (homestead or homestead reprice).
The returned GasTable's fields shouldn't, under any circumstances, be changed.
func (*ChainConfig) IsByzantium ¶ added in v1.7.0
func (c *ChainConfig) IsByzantium(num *big.Int) bool
func (*ChainConfig) IsConstantinople ¶ added in v1.8.2
func (c *ChainConfig) IsConstantinople(num *big.Int) bool
func (*ChainConfig) IsDAOFork ¶ added in v1.6.0
func (c *ChainConfig) IsDAOFork(num *big.Int) bool
IsDAO returns whether num is either equal to the DAO fork block or greater.
func (*ChainConfig) IsHomestead ¶ added in v1.4.19
func (c *ChainConfig) IsHomestead(num *big.Int) bool
IsHomestead returns whether num is either equal to the homestead block or greater.
func (*ChainConfig) String ¶ added in v1.5.3
func (c *ChainConfig) String() string
String implements the fmt.Stringer interface.
type CliqueConfig ¶ added in v1.6.0
type CliqueConfig struct { Period uint64 `json:"period"` // Number of seconds between blocks to enforce Epoch uint64 `json:"epoch"` // Epoch length to reset votes and checkpoint }
CliqueConfig is the consensus engine configs for proof-of-authority based sealing.
func (*CliqueConfig) String ¶ added in v1.6.0
func (c *CliqueConfig) String() string
String implements the stringer interface, returning the consensus engine details.
type ConfigCompatError ¶ added in v1.6.0
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 ¶ added in v1.6.0
func (err *ConfigCompatError) Error() string
type EthashConfig ¶ added in v1.6.0
type EthashConfig struct{}
EthashConfig is the consensus engine configs for proof-of-work based sealing.
func (*EthashConfig) String ¶ added in v1.6.0
func (c *EthashConfig) String() string
String implements the stringer interface, returning the consensus engine details.
type GasTable ¶ added in v1.4.19
type GasTable struct { ExtcodeSize uint64 ExtcodeCopy uint64 Balance uint64 SLoad uint64 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 }
type Rules ¶ added in v1.4.19
type Rules struct { ChainId *big.Int IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool IsByzantium bool }
Rules wraps ChainConfig and is merely syntatic sugar or can be used for functions that do not have or require information about the block.
Rules is a one time interface meaning that it shouldn't be used in between transition phases.
