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) Rules ¶
func (c *ChainConfig) Rules(num *big.Int) Rules
Rules ensures c's ChainID is not nil.
func (*ChainConfig) String ¶
func (c *ChainConfig) String() string
String implements the fmt.Stringer interface.
type CheckpointOracleConfig ¶
type CheckpointOracleConfig struct { Address common.Address `json:"address"` Signers []common.Address `json:"signers"` Threshold uint64 `json:"threshold"` }
CheckpointOracleConfig represents a set of checkpoint contract(which acts as an oracle) config which used for light client checkpoint syncing.
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 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 EthashConfig ¶
type EthashConfig struct{}
EthashConfig is the consensus engine configs for proof-of-work based sealing.
func (*EthashConfig) String ¶

String implements the stringer interface, returning the consensus engine details.
type Rules ¶
type Rules struct { ChainID *big.Int IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool IsByzantium, IsConstantinople, IsPetersburg, IsIstanbul bool IsBerlin, IsLondon, IsCatalyst 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.
type TrustedCheckpoint ¶

func (c *TrustedCheckpoint) Empty() bool
Empty returns an indicator whether the checkpoint is regarded as empty.
func (*TrustedCheckpoint) Hash ¶
func (c *TrustedCheckpoint) Hash() common.Hash
