	settings Settings,
	lastAcceptedHash common.Hash,

) (*Ethereum, error)

New creates a new Ethereum object (including the initialisation of the common Ethereum object)

func (*Ethereum) APIs 

func (s *Ethereum) APIs() []rpc.API

APIs return the collection of RPC services the ethereum package offers. NOTE, some of these services probably need to be moved to somewhere else.

func (*Ethereum) LastAcceptedBlock 

func (s *Ethereum) LastAcceptedBlock() *types.Block

func (*Ethereum) Miner 

func (s *Ethereum) Miner() *miner.Miner

func (*Ethereum) NetVersion 

func (s *Ethereum) NetVersion() uint64

func (*Ethereum) SetEtherbase 

func (s *Ethereum) SetEtherbase(etherbase common.Address)

SetEtherbase sets the mining reward address.

func (*Ethereum) Start 

func (s *Ethereum) Start()

Start implements node.Lifecycle, starting all internal goroutines needed by the Ethereum protocol implementation.

func (*Ethereum) StateAtBlock 

func (eth *Ethereum) StateAtBlock(ctx context.Context, block *types.Block, reexec uint64, base *state.StateDB, readOnly bool, preferDisk bool) (statedb *state.StateDB, release tracers.StateReleaseFunc, err error)

StateAtBlock retrieves the state database associated with a certain block. If no state is locally available for the given block, a number of blocks are attempted to be reexecuted to generate the desired state. The optional base layer statedb can be provided which is regarded as the statedb of the parent block.

An additional release function will be returned if the requested state is available. Release is expected to be invoked when the returned state is no longer needed. Its purpose is to prevent resource leaking. Though it can be noop in some cases.

Parameters:

  • block: The block for which we want the state(state = block.Root)
  • reexec: The maximum number of blocks to reprocess trying to obtain the desired state
  • base: If the caller is tracing multiple blocks, the caller can provide the parent state continuously from the callsite.
  • readOnly: If true, then the live 'blockchain' state database is used. No mutation should be made from caller, e.g. perform Commit or other 'save-to-disk' changes. Otherwise, the trash generated by caller may be persisted permanently.
  • preferDisk: this arg can be used by the caller to signal that even though the 'base' is provided, it would be preferable to start from a fresh state, if we have it on disk.

func (*Ethereum) StateAtNextBlock 

func (eth *Ethereum) StateAtNextBlock(ctx context.Context, parent *types.Block, nextBlock *types.Block, reexec uint64, base *state.StateDB, readOnly bool, preferDisk bool) (*state.StateDB, tracers.StateReleaseFunc, error)

StateAtNextBlock is a helper function that returns the state at the next block. It wraps StateAtBlock and handles the case where Upgrades are applied to the next block. This is different than using StateAtBlock with [nextBlock] because it will apply the upgrades to the [parent] state before returning it.

func (*Ethereum) Stop 

func (s *Ethereum) Stop() error

Stop implements node.Lifecycle, terminating all internal goroutines used by the Ethereum protocol. FIXME remove error from type if this will never return an error

func (*Ethereum) TxPool 

func (s *Ethereum) TxPool() *txpool.TxPool

type EthereumAPI 

type EthereumAPI struct {
	// contains filtered or unexported fields
}

EthereumAPI provides an API to access Ethereum full node-related information.

Coinbase is the address that mining rewards will be send to (alias for Etherbase).

func (*EthereumAPI) Etherbase 

func (api *EthereumAPI) Etherbase() (common.Address, error)

Etherbase is the address that mining rewards will be send to.

type Settings 

type Settings struct {
	MaxBlocksPerRequest int64 // Maximum number of blocks to serve per getLogs request

type StorageRangeResult 

type StorageRangeResult struct {
	Storage storageMap   `json:"storage"`

}

StorageRangeResult is the result of a debug_storageRangeAt API call.
