Functions

func DAODrainList

Types

type ChainConfig

type ChainConfig struct {
	ChainId *big.Int `json:"chainId"` // Chain id identifies the current chain and is used for replay protection

	PanguBlock         *big.Int `json:"panguBlock,omitempty"`         // Pangu switch block (nil = no fork, 0 = already pangu)
	RemoveEmptyAccount bool     `json:"removeEmptyAccount,omitempty"` //Replace EIP158 check and should be set to true

	NuwaBlock *big.Int `json:"nuwaBlock,omitempty"` // nuwa switch block (nil = no fork, 0 = already on nuwa)

	// Various consensus engines
	Ethash *EthashConfig `json:"ethash,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. default is to omitempty Accounts EIP158

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 (pangu or pangu reprice).

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

func (*ChainConfig) IsNuwa

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

func (*ChainConfig) IsPangu

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

IsPangu returns whether num is either equal to the pangu block or greater.

func (*ChainConfig) IsRemoveEmptyAccount

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

Remove the Empty account To replace the EIP158Block check Default is to remove all empty Accounts

func (*ChainConfig) Rules

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

Pangu 0.8 version

func (*ChainConfig) String

func (c *ChainConfig) String() string

String implements the fmt.Stringer interface. Removed the uncessary

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
}

Not used 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 EthashConfig

type EthashConfig struct{}

EthashConfig is the consensus engine configs for proof-of-work based sealing.

func (*EthashConfig) String

func (c *EthashConfig) 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
}

type Rules

type Rules struct {
	ChainId *big.Int
	IsPangu bool
	IsNuwa  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 ScsKind

type ScsKind int64

const (
	None ScsKind = iota
	ConsensusScs
	MonitorScs
	BackupScs
	MatchSelTarget
)
