func (*ChainConfig) IsMuirGlacier ¶
func (c *ChainConfig) IsMuirGlacier(num *big.Int) bool
IsMuirGlacier returns whether num is either equal to the Muir Glacier (EIP-2384) fork block or greater.
func (*ChainConfig) IsPetersburg ¶
func (c *ChainConfig) IsPetersburg(num *big.Int) bool
IsPetersburg returns whether num is either - equal to or greater than the PetersburgBlock fork block, - OR is nil, and Constantinople is active
func (*ChainConfig) IsPrague ¶
func (c *ChainConfig) IsPrague(num *big.Int, time uint64) bool
IsPrague returns whether time is either equal to the Prague fork time or greater.
func (*ChainConfig) IsShanghai ¶
func (c *ChainConfig) IsShanghai(num *big.Int, time uint64) bool
IsShanghai returns whether time is either equal to the Shanghai fork time or greater.
func (*ChainConfig) IsTerminalPoWBlock ¶
IsTerminalPoWBlock returns whether the given block is the last block of PoW stage.
func (*ChainConfig) IsVerkle ¶
func (c *ChainConfig) IsVerkle(num *big.Int, time uint64) bool
IsVerkle returns whether time is either equal to the Verkle fork time or greater.
func (*ChainConfig) LatestFork ¶ added in v1.14.6
func (c *ChainConfig) LatestFork(time uint64) forks.Fork
LatestFork returns the latest time-based fork that would be active for the given time.
type CliqueConfig ¶
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 ¶
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 if block based forking StoredBlock, NewBlock *big.Int // timestamps of the stored and new configurations if time based forking StoredTime, NewTime *uint64 // the block number to which the local chain must be rewound to correct the error RewindToBlock uint64 // the timestamp to which the local chain must be rewound to correct the error RewindToTime 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 EthashConfig ¶
type EthashConfig struct{}
EthashConfig is the consensus engine configs for proof-of-work based sealing.
func (EthashConfig) String ¶
func (c EthashConfig) String() string
String implements the stringer interface, returning the consensus engine details.
type Rules ¶
type Rules struct { ChainID *big.Int IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool IsEIP2929, IsEIP4762 bool IsByzantium, IsConstantinople, IsPetersburg, IsIstanbul bool IsBerlin, IsLondon bool IsMerge, IsShanghai, IsCancun, IsPrague bool IsVerkle bool }
Rules wraps ChainConfig and is merely syntactic 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.
