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.

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 DbftConfig added in v0.8.1 

type DbftConfig struct {
	Period uint64 `json:"period"` // Number of seconds between blocks to enforce
	Epoch  uint64 `json:"epoch"`  // Epoch length to reset votes and checkpoint
}

DbftConfig is the consensus engine configs for proof-of-authority based sealing.

func (*DbftConfig) String added in v0.8.1 

func (c *DbftConfig) String() string

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

type DebConfig 

type DebConfig struct {
	FairPubKey string   `json:"fairPubKey"`
	GasLimit   uint64   `json:"gasLimit"`
	GasPrice   uint64   `json:"gasPrice"`
	FnFeeRate  *big.Int `json:"fairFee"`
}

func (*DebConfig) FairAddr 

func (c *DebConfig) FairAddr() common.Address

func (c *DebConfig) GetFnFeeRate() *big.Int

func (*DebConfig) SetFairPubKey added in v0.8.1 

func (c *DebConfig) SetFairPubKey(fairPubKey string)

func (*DebConfig) SetFnFeeRate added in v0.7.6 

func (c *DebConfig) SetFnFeeRate(fairFeeRate *big.Int)

func (*DebConfig) String 

func (c *DebConfig) String() string

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, IsConstantinople             bool
	IsPohang                                  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.
