Types ¶

type BlockChain ¶

type BlockChain struct {
	*ledger.Ledger

	SideBlockscription feed.Subscription
	// contains filtered or unexported fields
}

BlockChain manages chain imports, reverts, chain reorganisations.

func NewBlockChain ¶

func NewBlockChain(cfg *ledger.Config, chainCfg *params.ChainConfig, statedb state.Database, db db.Database, engine consensus.Engine, vmCfg *vm.Config) (*BlockChain, error)

NewBlockChain returns a fully initialised block chain using information available in the database.

func (*BlockChain) Config ¶

func (bc *BlockChain) Config() *params.ChainConfig

func (*BlockChain) CurrentBlock ¶

func (bc *BlockChain) CurrentBlock() *types.Block

CurrentBlock retrieves the current head block of the canonical chain.

func (*BlockChain) ExecActions ¶

func (bc *BlockChain) ExecActions(statedb *state.StateDB, actions []*types.Action)

ExecActions execute actions

func (*BlockChain) ExecTransaction ¶

func (bc *BlockChain) ExecTransaction(author *utils.Address,
	dposcontext *types.DposContext,
	gp *utils.GasPool, statedb *state.StateDB, header *types.BlockHeader,
	tx *types.Transaction, usedGas *uint64, cfg vm.Config) ([]byte, *types.Receipt, uint64, error)

ExecTransaction execute transaction and return receipts

func (*BlockChain) ExportN ¶

func (bc *BlockChain) ExportN(w io.Writer, first uint64, last uint64) error

ExportN writes a subset of the active chain to the given writer.

func (*BlockChain) GetCurrentInfo ¶

func (bc *BlockChain) GetCurrentInfo() (*types.Block, *state.StateDB, error)

GetCurrentInfo return current info

func (*BlockChain) InsertChain ¶

func (bc *BlockChain) InsertChain(blocks types.Blocks) (int, error)

func (*BlockChain) PostEvent ¶

func (bc *BlockChain) PostEvent(event interface{})

func (*BlockChain) SetAddActionInterface ¶

func (bc *BlockChain) SetAddActionInterface(tp exec.ITxPool)

func (*BlockChain) State ¶

func (bc *BlockChain) State() (*state.StateDB, error)

State returns a new mutable state based on the current HEAD block.

func (*BlockChain) StateAt ¶

func (bc *BlockChain) StateAt(root utils.Hash) (*state.StateDB, error)

StateAt returns a new mutable state based on a particular point in time.

func (*BlockChain) Stop ¶

func (bc *BlockChain) Stop()

Stop stops the blockchain service.

func (*BlockChain) SubscribeChainBlockEvent ¶

func (bc *BlockChain) SubscribeChainBlockEvent(ch chan<- feed.BlockAndLogsEvent) feed.Subscription

SubscribeChainBlockEvent registers a subscription of Blockfeed.

func (*BlockChain) SubscribeSideBlockEvent ¶

func (bc *BlockChain) SubscribeSideBlockEvent(ch chan<- feed.ForkBlockEvent) feed.Subscription

SubscribeSideBlockEvent registers a subscription of Blockfeed.

func (*BlockChain) WriteBlockWithState ¶

func (bc *BlockChain) WriteBlockWithState(block *types.Block, receipts types.Receipts, state *state.StateDB) (bool, error)

WriteBlockWithState write the block to the chain and get the status.

func (*BlockChain) WriteBlockWithoutState ¶

func (bc *BlockChain) WriteBlockWithoutState(block *types.Block, td *big.Int) error

WriteBlockWithoutState writes only the block and its metadata to the database, but does not write any state.
