Types

type ChainConfig

	// Various consensus engines
	Dpor *DporConfig `json:"dpor,omitempty" toml:"dpor,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 ChainConfigInfo 

func ChainConfigInfo() *ChainConfig

this contains all the changes we have made to the cpchain protocol. serves as the *default* config.

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) IsCpchain 

func (c *ChainConfig) IsCpchain() bool

IsCpchain returns if it is CpchainDawn era.

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 DporConfig 

type DporConfig struct {
	Period                uint64                    `json:"period"                toml:"period"`             // Number of seconds between blocks to enforce
	TermLen               uint64                    `json:"termLen"               toml:"termLen"`            // Term length to reset votes and checkpoint
	ViewLen               uint64                    `json:"viewLen"               toml:"viewLen"`            // View length of blocks one signer can seal in one committee
	FaultyNumber          uint64                    `json:"faultyNumber"          toml:"faultyNumber"`       // Number of faulty validators in validator committee
	MaxInitBlockNumber    uint64                    `json:"maxInitBlockNumber"    toml:"maxInitBlockNumber"` // The maximum block number which uses default proposers
	Contracts             map[string]common.Address `json:"contracts"             toml:"contracts"`
	ProxyContractRegister common.Address            `json:"proxyContractRegister" toml:"proxyContractRegister"`
	ImpeachTimeout        time.Duration             `json:"impeachTimeout" toml:"impeachTimeout"`
}

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

func (*DporConfig) BlockDelay 

func (c *DporConfig) BlockDelay() time.Duration

func (*DporConfig) Certificate 

func (c *DporConfig) Certificate(n uint64) bool

func (*DporConfig) ImpeachCertificate 

func (c *DporConfig) ImpeachCertificate(n uint64) bool

func (*DporConfig) PeriodDuration 

func (c *DporConfig) PeriodDuration() time.Duration

func (*DporConfig) String 

func (c *DporConfig) String() string

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

func (*DporConfig) ValidatorsLen 

func (c *DporConfig) ValidatorsLen() uint64

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 ethereum phases.

type Rules 

type Rules struct {
	ChainID   *big.Int
	IsCpchain 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 RunMode 

type RunMode string
const (
	Dev         RunMode = "dev"
	Testnet     RunMode = "testnet"
	Mainnet     RunMode = "mainnet"
	TestMainnet RunMode = "testmainnet"
	Testcase    RunMode = "testcase"
