var ( // ErrRemoteStale is returned by the validator if a remote fork checksum is a // subset of our already applied forks, but the announced next fork block is // not on our already passed chain. ErrRemoteStale = errors.New("remote needs update") // ErrLocalIncompatibleOrStale is returned by the validator if a remote fork // checksum does not match any local checksum variation, signalling that the // two chains have diverged in the past at some point (possibly at genesis). ErrLocalIncompatibleOrStale = errors.New("local incompatible or needs update") )

func NewStaticFilter ¶
func NewStaticFilter(config *params.ChainConfig, genesis common.Hash) Filter
NewStaticFilter creates a filter at block zero.
type ID ¶
type ID struct {
Hash [4]byte // CRC32 checksum of the genesis block and passed fork block numbers
Next uint64 // Block number of the next upcoming fork, or 0 if no forks are known
}
