Types

type ChainConfig 

type ChainConfig struct {

	ChainLogger log.Logger `json:"-"`
}

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 NewChildChainConfig 

func NewChildChainConfig(childChainID string) *ChainConfig

Create a new Chain Config based on the Chain ID, for child chain creation purpose

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) IsConstantinople 

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

func (*ChainConfig) IsEIP150 

func (c *ChainConfig) IsEIP150(num *big.Int) bool

func (*ChainConfig) IsEIP155 

func (c *ChainConfig) IsEIP155(num *big.Int) bool

func (*ChainConfig) IsEIP158 

func (c *ChainConfig) IsEIP158(num *big.Int) bool

func (*ChainConfig) IsEWASM 

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

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) IsIstanbul 

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

IsIstanbul returns whether num is either equal to the Istanbul fork block or greater.

func (*ChainConfig) IsMainChain 

func (c *ChainConfig) IsMainChain() bool

Check whether is on main chain or not

func (*ChainConfig) IsPetersburg 

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

IsPetersburg returns whether num is either - equal to or greater than the PetersburgBlock fork block, - OR is nil, and Constantinople is active

func (*ChainConfig) Rules 

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

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 GasTable 

type GasTable struct {
	ExtcodeSize uint64
	ExtcodeCopy uint64
	ExtcodeHash 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 GeneralConfig 

type GeneralConfig struct {

	// Whether doing performance test, will remove some limitations and cause system more frigile
	PerfTest bool `json:"perfTest,omitempty"`
}

configuations in this structure is read-only, it gives a way to put/get general settings

type IPBFTConfig 

type IPBFTConfig struct {
	Epoch          uint64 `json:"epoch"`  // Epoch length to reset votes and checkpoint
	ProposerPolicy uint64 `json:"policy"` // The policy for proposer selection
}

IPBFTConfig is the consensus engine configs for Istanbul based sealing.

func (*IPBFTConfig) String 

func (c *IPBFTConfig) String() string

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

type Rules 

type Rules struct {
	ChainId                                                 *big.Int
	IsHomestead, IsEIP150, IsEIP155, IsEIP158               bool
	IsByzantium, IsConstantinople, IsPetersburg, IsIstanbul bool
}

Rules wraps ChainConfig and is merely syntactic 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.
