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 ¶

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.
