// 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

func (err *ConfigCompatError) Error() string
type CphashConfig ¶
type CphashConfig struct{}
CphashConfig is the consensus engine configs for proof-of-work based sealing.
