Types

type AlienConfig 

type AlienConfig struct {
	Period           uint64           `json:"period"`           // Number of seconds between blocks to enforce
	Epoch            uint64           `json:"epoch"`            // Epoch length to reset votes and checkpoint
	MaxSignerCount   uint64           `json:"maxSignersCount"`  // Max count of signers
	MinVoterBalance  *big.Int         `json:"minVoterBalance"`  // Min voter balance to valid this vote
	GenesisTimestamp uint64           `json:"genesisTimestamp"` // The LoopStartTime of first Block
	SelfVoteSigners  []common.Address `json:"signers"`          // Signers vote by themselves to seal the block, make sure the signer accounts are pre-funded
}

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

func (*AlienConfig) String 

func (c *AlienConfig) String() string

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

type ChainConfig 

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

	HomesteadBlock *big.Int `json:"homesteadBlock,omitempty"` // Homestead switch block (nil = no fork, 0 = already homestead)

	// EIP150 implements the Gas price changes (https://github.com/ethereum/EIPs/issues/150)
	EIP150Block *big.Int    `json:"eip150Block,omitempty"` // EIP150 HF block (nil = no fork)
	EIP150Hash  common.Hash `json:"eip150Hash,omitempty"`  // EIP150 HF hash (needed for header only clients as only gas pricing changed)

	EIP155Block *big.Int `json:"eip155Block,omitempty"` // EIP155 HF block
	EIP158Block *big.Int `json:"eip158Block,omitempty"` // EIP158 HF block

	ByzantiumBlock      *big.Int `json:"byzantiumBlock,omitempty"`      // Byzantium switch block (nil = no fork, 0 = already on byzantium)
	ConstantinopleBlock *big.Int `json:"constantinopleBlock,omitempty"` // Constantinople switch block (nil = no fork, 0 = already activated)

	// Various consensus engines
	Ethash *EthashConfig `json:"ethash,omitempty"`
	Clique *CliqueConfig `json:"clique,omitempty"`
	Alien  *AlienConfig  `json:"alien,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 (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) 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

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 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
	IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool
	IsByzantium                               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.
