const ( Wei = 1 Kwei = 1e3 Mwei = 1e6 Gwei = 1e9 Microvnt = 1e12 Millivnt = 1e15 Vnt = 1e18 )
These are the multipliers for vnt denominations. Example: To get the wei value of an amount in 'douglas', use
new(big.Int).Mul(value, big.NewInt(params.Douglas))

Functions ¶
func VersionWithCommit ¶
Types ¶
type ChainConfig ¶
type ChainConfig struct {
ChainID *big.Int `json:"chainId"` // chainId identifies the current chain and is used for replay protection
HubbleBlock *big.Int `json:"HubbleBlock,omitempty"` // Hubble switch block (nil = no fork, 0 = already hubble)
// Various consensus engines
Dpos *DposConfig `json:"dpos,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 .
The returned GasTable's fields shouldn't, under any circumstances, be changed.
func (*ChainConfig) IsHubble ¶
func (c *ChainConfig) IsHubble(num *big.Int) bool
IsHubble returns whether num is either equal to the hubble 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 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 DposConfig ¶
type DposConfig struct {
Period uint64 `json:"period"` // Number of seconds between blocks to enforce
WitnessesNum int `json:"witnessesnum"` // Number of witnesses
WitnessesUrl []string `json:"witnessesUrl"`
}
func (*DposConfig) String ¶
func (c *DposConfig) String() string
String implements the stringer interface, returning the consensus engine details.
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
}
GasTable organizes gas prices for different hubble phases.
