Version holds the textual version string.

func IsBech32SegwitPrefix ¶
Types ¶
type ChainConfig ¶
type ChainConfig struct {
// chainId identifies the current chain and is used for replay protection
ChainID *big.Int `json:"chainId"`
// Various consensus engines
Pow *PowConfig
}
ChainConfig is the core config which determines the blockchain settings.
func (*ChainConfig) CheckCompatible ¶
func (c *ChainConfig) CheckCompatible(newcfg *ChainConfig, height uint64) *ConfigCompatError
CheckCompatible checks whether scheduled fork transitions have been imported with a mismatching chain configuration.
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
