Version holds the textual version string.
Functions ¶
func DAODrainList ¶
DAODrainList is the list of accounts whose full balances will be moved into a refund contract at the beginning of the dao-fork block.
func VersionWithCommit ¶
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,omitempty"` // Homestead switch block (nil = no fork, 0 = already homestead) DAOForkBlock *big.Int `json:"daoForkBlock,omitempty"` // TheDAO hard-fork switch block (nil = no fork) DAOForkSupport bool `json:"daoForkSupport,omitempty"` // Whether the nodes supports or opposes the DAO hard-fork // EIP150 implements the Gas price changes (https://github.com/wiseplat/EIPs/issues/150) EIP150Block *big.Int `json:"eip150Block,omitempty"` // EIP150 HF block (nil = no fork) EIP150Hash common.Hash `json:"eip150Hash,omitempty"` // EIP150 HF hash (needed for header only clients as only gas pricing changed) EIP155Block *big.Int `json:"eip155Block,omitempty"` // EIP155 HF block EIP158Block *big.Int `json:"eip158Block,omitempty"` // EIP158 HF block ByzantiumBlock *big.Int `json:"byzantiumBlock,omitempty"` // Byzantium switch block (nil = no fork, 0 = already on byzantium) // Various consensus engines Wshash *WshashConfig `json:"wshash,omitempty"` Clique *CliqueConfig `json:"clique,omitempty"` }
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
func (*ChainConfig) IsDAOFork ¶
func (c *ChainConfig) IsDAOFork(num *big.Int) bool
IsDAO returns whether num is either equal to the DAO 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) 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 GasTable ¶
type GasTable struct { ExtcodeSize uint64 ExtcodeCopy 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 }
type Rules ¶
type Rules struct { ChainId *big.Int IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool IsByzantium bool }
Rules wraps ChainConfig and is merely syntatic 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.
type WshashConfig ¶
type WshashConfig struct{}
WshashConfig is the consensus engine configs for proof-of-work based sealing.
func (*WshashConfig) String ¶
func (c *WshashConfig) String() string
String implements the stringer interface, returning the consensus engine details.
