Functions

func CreateConsensusEngine

func CreateConsensusEngine(config *params.ChainConfig, db ethdb.Database) (consensus.Engine, error)

CreateConsensusEngine creates a consensus engine for the given chain config. Clique is allowed for now to live standalone, but ethash is forbidden and can only exist on already merged networks.

Types

type Config

type Config struct {
	// The genesis block, which is inserted if the database is empty.
	// If nil, the Ethereum main net block is used.
	Genesis *core.Genesis `toml:",omitempty"`

	// Network ID separates blockchains on the peer-to-peer networking level. When left
	// zero, the chain ID is used as network ID.
	NetworkId uint64
	SyncMode  downloader.SyncMode

	// This can be set to list of enrtree:// URLs which will be queried for
	// nodes to connect to.
	EthDiscoveryURLs  []string
	SnapDiscoveryURLs []string

	// State options.
	NoPruning  bool // Whether to disable pruning and flush everything to disk
	NoPrefetch bool // Whether to disable prefetching and only load state on demand

	// Deprecated: use 'TransactionHistory' instead.
	TxLookupLimit uint64 `toml:",omitempty"` // The maximum number of blocks from head whose tx indices are reserved.

	TransactionHistory uint64 `toml:",omitempty"` // The maximum number of blocks from head whose tx indices are reserved.
	StateHistory       uint64 `toml:",omitempty"` // The maximum number of blocks from head whose state histories are reserved.

	// State scheme represents the scheme used to store ethereum states and trie
	// nodes on top. It can be 'hash', 'path', or none which means use the scheme
	// consistent with persistent state.
	StateScheme string `toml:",omitempty"`

	// RequiredBlocks is a set of block number -> hash mappings which must be in the
	// canonical chain of all remote peers. Setting the option makes geth verify the
	// presence of these blocks for every new peer connection.
	RequiredBlocks map[uint64]common.Hash `toml:"-"`

	// Database options
	SkipBcVersionCheck bool `toml:"-"`
	DatabaseHandles    int  `toml:"-"`

	FilterLogCacheSize int

	// Mining options
	Miner miner.Config

	// Transaction pool options
	TxPool   legacypool.Config
	BlobPool blobpool.Config

	// Gas Price Oracle options

	// RPCGasCap is the global gas cap for eth-call variants.
	RPCGasCap uint64

	// RPCEVMTimeout is the global timeout for eth-call.
	RPCEVMTimeout time.Duration

	// RPCTxFeeCap is the global transaction fee(price * gaslimit) cap for
	// send-transaction variants. The unit is ether.
	RPCTxFeeCap float64

	OverrideCancun *uint64 `toml:",omitempty"`

	// OverrideVerkle (TODO: remove after the fork)
	OverrideVerkle *uint64 `toml:",omitempty"`
}

Config contains configuration options for ETH and LES protocols.

func (Config) MarshalTOML
