const (
	Wei   = 1
	GWei  = 1e9
	Ether = 1e18
)

These are the multipliers for ether denominations. Example: To get the wei value of an amount in 'gwei', use 

new(big.Int).Mul(value, big.NewInt(params.GWei))

}

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) AvalancheRules 

func (c *ChainConfig) AvalancheRules(blockNum, blockTimestamp *big.Int) Rules

AvalancheRules returns the Avalanche modified rules to support Avalanche network upgrades

func (*ChainConfig) CheckCompatible 

func (c *ChainConfig) CheckCompatible(newcfg *ChainConfig, height uint64, timestamp uint64) *ConfigCompatError

CheckCompatible checks whether scheduled fork transitions have been imported with a mismatching chain configuration.

func (*ChainConfig) CheckConfigForkOrder 

func (c *ChainConfig) CheckConfigForkOrder() error

CheckConfigForkOrder checks that we don't "skip" any forks, geth isn't pluggable enough to guarantee that forks can be implemented in a different order than on official networks

func (*ChainConfig) CheckConfigurePrecompiles added in v0.1.2 

func (c *ChainConfig) CheckConfigurePrecompiles(parentTimestamp *big.Int, blockContext precompile.BlockContext, statedb precompile.StateDB)

CheckConfigurePrecompiles checks if any of the precompiles specified by the chain config are enabled or disabled by the block transition from [parentTimestamp] to the timestamp set in [blockContext]. If this is the case, it calls [Configure] or [Deconfigure] to apply the necessary state transitions for the upgrade. This function is called: - within genesis setup to configure the starting state for precompiles enabled at genesis, - during block processing to update the state before processing the given block.

func (*ChainConfig) CheckPrecompilesCompatible added in v0.2.8 

func (c *ChainConfig) CheckPrecompilesCompatible(precompileUpgrades []PrecompileUpgrade, lastTimestamp *big.Int) *ConfigCompatError

CheckPrecompilesCompatible checks if [precompileUpgrades] are compatible with [c] at [headTimestamp]. Returns a ConfigCompatError if upgrades already forked at [headTimestamp] are missing from [precompileUpgrades]. Upgrades not already forked may be modified or absent from [precompileUpgrades]. Returns nil if [precompileUpgrades] is compatible with [c]. Assumes given timestamp is the last accepted block timestamp. This ensures that as long as the node has not accepted a block with a different rule set it will allow a new upgrade to be applied as long as it activates after the last accepted block.

func (*ChainConfig) EnabledStatefulPrecompiles added in v0.2.8 

func (c *ChainConfig) EnabledStatefulPrecompiles(blockTimestamp *big.Int) []precompile.StatefulPrecompileConfig

EnabledStatefulPrecompiles returns a slice of stateful precompile configs that have been activated through an upgrade.

func (*ChainConfig) GetActivePrecompiles added in v0.3.0 

func (c *ChainConfig) GetActivePrecompiles(blockTimestamp *big.Int) PrecompileUpgrade

func (*ChainConfig) GetContractDeployerAllowListConfig added in v0.2.8

GetContractDeployerAllowListConfig returns the latest forked ContractDeployerAllowListConfig specified by [c] or nil if it was never enabled.

func (*ChainConfig) GetContractNativeMinterConfig added in v0.2.8 

func (c *ChainConfig) GetContractNativeMinterConfig(blockTimestamp *big.Int) *precompile.ContractNativeMinterConfig

GetContractNativeMinterConfig returns the latest forked ContractNativeMinterConfig specified by [c] or nil if it was never enabled.

func (*ChainConfig) GetFeeConfig 

func (c *ChainConfig) GetFeeConfig() commontype.FeeConfig

GetFeeConfig returns the FeeConfig

func (*ChainConfig) GetFeeConfigManagerConfig added in v0.2.8 

func (c *ChainConfig) GetFeeConfigManagerConfig(blockTimestamp *big.Int) *precompile.FeeConfigManagerConfig

GetFeeConfigManagerConfig returns the latest forked FeeManagerConfig specified by [c] or nil if it was never enabled.

func (*ChainConfig) GetTxAllowListConfig added in v0.2.8 

func (c *ChainConfig) GetTxAllowListConfig(blockTimestamp *big.Int) *precompile.TxAllowListConfig

GetTxAllowListConfig returns the latest forked TxAllowListConfig specified by [c] or nil if it was never enabled.

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.

	StoredConfig, NewConfig *big.Int
	// the block number to which the local chain must be rewound to correct the error
	RewindTo uint64

type NetworkUpgrades added in v0.2.8 

type NetworkUpgrades struct {
	SubnetEVMTimestamp *big.Int `json:"subnetEVMTimestamp,omitempty"` // A placeholder for the latest avalanche forks (nil = no fork, 0 = already activated)
}

NetworkUpgrades contains timestamps that enable avalanche network upgrades.

func (n *NetworkUpgrades) CheckCompatible(newcfg *NetworkUpgrades, headTimestamp *big.Int) *ConfigCompatError

type PrecompileUpgrade added in v0.2.8 

type PrecompileUpgrade struct {
	ContractDeployerAllowListConfig *precompile.ContractDeployerAllowListConfig `json:"contractDeployerAllowListConfig,omitempty"` // Config for the contract deployer allow list precompile
	ContractNativeMinterConfig      *precompile.ContractNativeMinterConfig      `json:"contractNativeMinterConfig,omitempty"`      // Config for the native minter precompile
	TxAllowListConfig               *precompile.TxAllowListConfig               `json:"txAllowListConfig,omitempty"`               // Config for the tx allow list precompile
	FeeManagerConfig                *precompile.FeeConfigManagerConfig          `json:"feeManagerConfig,omitempty"`                // Config for the fee manager precompile

}

PrecompileUpgrade is a helper struct embedded in UpgradeConfig, representing each of the possible stateful precompile types that can be activated as a network upgrade.

type Rules 

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

	// Rules for Avalanche releases
	IsSubnetEVM bool

	// Optional stateful precompile rules
	IsContractDeployerAllowListEnabled bool
	IsContractNativeMinterEnabled      bool
	IsTxAllowListEnabled               bool
	IsFeeConfigManagerEnabled          bool

	// Precompiles maps addresses to stateful precompiled contracts that are enabled
	// for this rule set.
	// Note: none of these addresses should conflict with the address space used by
	// any existing precompiles.
	Precompiles map[common.Address]precompile.StatefulPrecompiledContract
}

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 UpgradeConfig added in v0.2.8 

type UpgradeConfig struct {
	// Config for blocks/timestamps that enable network upgrades.
	// Note: if NetworkUpgrades is specified in the JSON all previously activated
	// forks must be present or upgradeBytes will be rejected.
	NetworkUpgrades *NetworkUpgrades `json:"networkUpgrades,omitempty"`

	// Config for enabling and disabling precompiles as network upgrades.
	PrecompileUpgrades []PrecompileUpgrade `json:"precompileUpgrades,omitempty"`
}

UpgradeConfig includes the following configs that may be specified in upgradeBytes: - Timestamps that enable avalanche network upgrades, - Enabling or disabling precompiles as network upgrades.
