}

ChainConfig is the core config which determines the blockchain settings.

ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.

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.

func (*ChainConfig) GasTable 

func (c *ChainConfig) GasTable(num *big.Int) GasTable

GasTable returns the gas table corresponding to the current phase (homestead or homestead reprice).

The returned GasTable's fields shouldn't, under any circumstances, be changed.

func (*ChainConfig) IsByzantium 

func (c *ChainConfig) IsByzantium(num *big.Int) bool

IsByzantium returns whether num is either equal to the Byzantium fork block or greater.

func (*ChainConfig) IsConstantinople 

func (c *ChainConfig) IsConstantinople(num *big.Int) bool

IsConstantinople returns whether num is either equal to the Constantinople fork block or greater.

func (*ChainConfig) IsDAOFork 

func (c *ChainConfig) IsDAOFork(num *big.Int) bool

IsDAOFork returns whether num is either equal to the DAO fork block or greater.

func (*ChainConfig) IsEIP150 

func (c *ChainConfig) IsEIP150(num *big.Int) bool

IsEIP150 returns whether num is either equal to the EIP150 fork block or greater.

func (*ChainConfig) IsEIP155 

func (c *ChainConfig) IsEIP155(num *big.Int) bool

IsEIP155 returns whether num is either equal to the EIP155 fork block or greater.

func (*ChainConfig) IsEIP158 

func (c *ChainConfig) IsEIP158(num *big.Int) bool

IsEIP158 returns whether num is either equal to the EIP158 fork block or greater.

func (*ChainConfig) IsHomestead 

func (c *ChainConfig) IsHomestead(num *big.Int) bool

IsHomestead returns whether num is either equal to the homestead block or greater.

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 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 CuckooConfig added in v1.0.0 

type CuckooConfig struct{}

func (*CuckooConfig) String added in v1.0.0 

func (c *CuckooConfig) String() string

String implements the stringer interface, returning the consensus engine details.

type GasTable 

type GasTable struct {
	ExtcodeSize uint64
	ExtcodeCopy uint64
	ExtcodeHash uint64
	Balance     uint64
	SLoad       uint64
	Calls       uint64
	Suicide     uint64

	ExpByte uint64

	// CreateBySuicide occurs when the
	// refunded account is one that does
	// not exist. This logic is similar
	// to call. May be left nil. Nil means
	// not charged.
	CreateBySuicide uint64
}

GasTable organizes gas prices for different ethereum phases.

type Rules 

type Rules struct {
	ChainID                                   *big.Int
	IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool
	IsByzantium                               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.
