Types ¶
type ChainConfig ¶
type ChainConfig struct { ChainId *big.Int `json:"chainId"` // Chain id identifies the current chain and is used for replay protection HomesteadBlock *big.Int `json:"homesteadBlock"` // Homestead switch block (nil = no fork, 0 = already homestead) DAOForkBlock *big.Int `json:"daoForkBlock"` // TheDAO hard-fork switch block (nil = no fork) DAOForkSupport bool `json:"daoForkSupport"` // Whether the nodes supports or opposes the DAO hard-fork // EIP150 implements the Gas price changes (https://github.com/ethereum/EIPs/issues/150) EIP150Block *big.Int `json:"eip150Block"` // EIP150 HF block (nil = no fork) EIP150Hash common.Hash `json:"eip150Hash"` // EIP150 HF hash (fast sync aid) EIP155Block *big.Int `json:"eip155Block"` // EIP155 HF block EIP158Block *big.Int `json:"eip158Block"` // EIP158 HF block }
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) 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) IsHomestead ¶
func (c *ChainConfig) IsHomestead(num *big.Int) bool
IsHomestead returns whether num is either equal to the homestead block or greater.
func (*ChainConfig) String ¶
func (c *ChainConfig) String() string
String implements the Stringer interface.
type GasTable ¶
type GasTable struct { ExtcodeSize *big.Int ExtcodeCopy *big.Int Balance *big.Int SLoad *big.Int Calls *big.Int Suicide *big.Int ExpByte *big.Int // 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 *big.Int }
