}

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

IsByzantium returns whether num is either equal to the Byzantium fork block or greater.

func (*ChainConfig) IsConstantinople 

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

IsConstantinople returns whether num is either equal to the Constantinople fork block or greater.

func (*ChainConfig) IsDAOFork 

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

IsDAOFork returns whether num is either equal to the DAO fork block or greater.

func (*ChainConfig) IsEIP150 

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

IsEIP150 returns whether num is either equal to the EIP150 fork block or greater.

func (*ChainConfig) IsEIP155 

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

IsEIP155 returns whether num is either equal to the EIP155 fork block or greater.

func (*ChainConfig) IsEIP158 

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

IsEIP158 returns whether num is either equal to the EIP158 fork block or greater.

func (*ChainConfig) IsEWASM 

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

IsEWASM returns whether num represents a block number after the EWASM fork

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) 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 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 DaTongConfig 

type DaTongConfig struct {
	Period uint64 `json:"period"`
}

DaTongConfig is the consensus engine configs for proof-of-stake based sealing.

func (*DaTongConfig) String 

func (c *DaTongConfig) String() string

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

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
	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 Rules 

type Rules struct {
	ChainID                                   *big.Int
	IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool
	IsByzantium, IsConstantinople             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.

type TrustedCheckpoint 

type TrustedCheckpoint struct {
	Name         string      `json:"-"`
	SectionIndex uint64      `json:"sectionIndex"`
	SectionHead  common.Hash `json:"sectionHead"`
	CHTRoot      common.Hash `json:"chtRoot"`
	BloomRoot    common.Hash `json:"bloomRoot"`
}

TrustedCheckpoint represents a set of post-processed trie roots (CHT and BloomTrie) associated with the appropriate section index and head hash. It is used to start light syncing from this checkpoint and avoid downloading the entire header chain while still being able to securely access old headers/logs.
