Check provided chain id is on main chain or not

func VersionWithCommit 

func VersionWithCommit(gitCommit string) string

Types

type ChainConfig 

type ChainConfig struct {
	NeatChainId string   `json:"NeatChainId"` //NeatIO id identifies the current chain
	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
	NeatCon *NeatConConfig `json:"neatcon,omitempty"`

	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 NewSideChainConfig 

func NewSideChainConfig(sideChainID string) *ChainConfig

Create a new Chain Config based on the Chain ID, for side 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) IsMainChain 

func (c *ChainConfig) IsMainChain() bool

Check whether is on main chain or not

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 uint64
}

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 NeatConConfig added in v1.5.1 

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

NeatConConfig is the consensus engine configs for Istanbul based sealing.

func (*NeatConConfig) String added in v1.5.1 

func (c *NeatConConfig) 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 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.
