PrivateMinerAPI provides private RPC methods to control the miner. These methods can be abused by external users and must be considered insecure for use by untrusted users.

func NewPrivateMinerAPI 

func NewPrivateMinerAPI(e *CpchainService) *PrivateMinerAPI

NewPrivateMinerAPI create a new RPC service which controls the miner of this node.

func (*PrivateMinerAPI) SetCoinbase 

func (api *PrivateMinerAPI) SetCoinbase(coinbase common.Address) bool

func (*PrivateMinerAPI) SetExtra 

func (api *PrivateMinerAPI) SetExtra(extra string) (bool, error)

SetExtra sets the extra data string that is included when this miner mines a block.

func (*PrivateMinerAPI) SetGasPrice 

func (api *PrivateMinerAPI) SetGasPrice(gasPrice hexutil.Big) bool

SetGasPrice sets the minimum accepted gas price for the miner.

func (*PrivateMinerAPI) Start 

func (api *PrivateMinerAPI) Start(threads *int) error

Start the miner with the given number of threads. If threads is nil the number of workers started is equal to the number of logical CPUs that are usable by this process. If mining is already running, this method adjust the number of threads allowed to use.

func (*PrivateMinerAPI) Stop 

func (api *PrivateMinerAPI) Stop() bool

Stop the miner

type ProtocolManager 

type ProtocolManager struct {
	SubProtocols []p2p.Protocol
	// contains filtered or unexported fields
}

func NewProtocolManager 

func NewProtocolManager(config *configs.ChainConfig, mode downloader.SyncMode, networkID uint64, mux *event.TypeMux, txpool txPool, engine consensus.Engine, blockchain *core.BlockChain, chaindb database.Database, coinbase common.Address) (*ProtocolManager, error)

NewProtocolManager returns a new sub protocol manager. The cpchain sub protocol manages peers capable with the cpchain network.

func (*ProtocolManager) BroadcastBlock 

func (pm *ProtocolManager) BroadcastBlock(block *types.Block, propagate bool)

BroadcastBlock will either propagate a block to a subset of it's peers, or will only announce it's availability (depending what's requested).

func (*ProtocolManager) BroadcastTxs 

func (pm *ProtocolManager) BroadcastTxs(txs types.Transactions)

BroadcastTxs will propagate a batch of transactions to all peers which are not known to already have the given transaction.

func (*ProtocolManager) NodeInfo 

func (pm *ProtocolManager) NodeInfo() *NodeInfo

NodeInfo retrieves some protocol metadata about the running host node.

func (*ProtocolManager) Start 

func (pm *ProtocolManager) Start(maxPeers int)

Start starts all the blockchain synchronization mechanisms

func (*ProtocolManager) Stop 

func (pm *ProtocolManager) Stop()

Stop stops all

type PublicCpchainAPI 

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

PublicCpchainAPI provides an API to access cpchain full node-related information.

func NewPublicCpchainAPI 

func NewPublicCpchainAPI(e *CpchainService) *PublicCpchainAPI

NewPublicCpchainAPI creates a new cpchain protocol API for full nodes.

func (*PublicCpchainAPI) Coinbase 

func (api *PublicCpchainAPI) Coinbase() (common.Address, error)

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

func (*PublicCpchainAPI) Cpcbase 

func (api *PublicCpchainAPI) Cpcbase() (common.Address, error)

Coinbase is the address that mining rewards will be send to

type PublicDebugAPI 

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

PublicDebugAPI is the collection of cpchain full node APIs exposed over the public debugging endpoint.

func NewPublicDebugAPI 

func NewPublicDebugAPI(eth *CpchainService) *PublicDebugAPI

NewPublicDebugAPI creates a new API definition for the full node- related public debug methods of the cpchain service.

func (*PublicDebugAPI) DumpBlock 

func (api *PublicDebugAPI) DumpBlock(blockNr rpc.BlockNumber) (state.Dump, error)

DumpBlock retrieves the entire state of the database at a given block.

type StorageRangeResult 

type StorageRangeResult struct {
	Storage storageMap   `json:"storage"`
	NextKey *common.Hash `json:"nextKey"` // nil if Storage includes the last key in the trie.
}

StorageRangeResult is the result of a debug_storageRangeAt API call.

type TraceConfig 

type TraceConfig struct {
	*vm.LogConfig
	Tracer  *string
	Timeout *string
	Reexec  *uint64
}

TraceConfig holds extra parameters to trace functions.
