Functions

func ApplyMessage 

func ApplyMessage(evm *vm.EVM, tx txinterface.Message, gp *GasPool) ([]byte, uint64, bool, []uint, error)

ApplyMessage computes the new state by applying the given message against the old state within the environment.

ApplyMessage returns the bytes returned by any EVM execution (if it took place), the gas used (which includes gas refunds) and an error if it failed. An error always indicates a core error meaning that the message would always fail for that particular state and would never be accepted within a block.

func ApplyTransaction 

func ApplyTransaction(config *params.ChainConfig, bc ChainContext, author *common.Address, gp *GasPool, statedb *state.StateDBManage, header *types.Header, tx types.SelfTransaction, usedGas *uint64, cfg vm.Config) (*types.Receipt, uint64, []uint, error)

ApplyTransaction attempts to apply a transaction to the given state database and uses the input parameters for its environment. It returns the receipt for the transaction, gas used and an error if the transaction failed, indicating the block was invalid.

func BlackListFilter 

func BlackListFilter(tx types.SelfTransaction, state *state.StateDBManage, h *big.Int) bool

func CalcGasLimit 

func CalcGasLimit(parent *types.Block) uint64

CalcGasLimit computes the gas limit of the next block after parent. This is miner strategy, not consensus protocol.

func CanTransfer 

func CanTransfer(db vm.StateDBManager, addr common.Address, amount *big.Int, typ string) bool

CanTransfer checks wether there are enough funds in the address' account to make a transfer. This does not take the necessary gas in to account to make the transfer valid.

func CopyAddressSlice 

func CopyAddressSlice(Src *[]GenesisAddress) []common.Address

func GenerateChain 

func GenerateChain(config *params.ChainConfig, parent *types.Block, engine consensus.Engine, db mandb.Database, n int, gen func(int, *BlockGen)) ([]*types.Block, []types.Receipts)

GenerateChain creates a chain of n blocks. The first block's parent will be the provided parent. db is used to store intermediate states and should contain the parent's state trie.

The generator function is called with a new block generator for every block. Any transactions and uncles added to the generator become part of the block. If gen is nil, the blocks will be empty and their coinbase will be the zero address.

Blocks created by GenerateChain do not contain valid proof of work values. Inserting them into BlockChain requires use of FakePow or a similar non-validating proof of work implementation.

type BlockChain 

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

BlockChain represents the canonical chain given a database with a genesis block. The Blockchain manages chain imports, reverts, chain reorganisations.

Importing blocks in to the block chain happens according to the set of rules defined by the two stage Validator. Processing of blocks is done using the Processor which processes the included transaction. The validation of the state is done in the second part of the Validator. Failing results in aborting of the import.

The BlockChain also helps in returning blocks from **any** chain included in the database as well as blocks that represents the canonical chain. It's important to note that GetBlock can return any block and does not need to be included in the canonical one where as GetBlockByNumber always represents the canonical chain.

	// contains filtered or unexported fields
}

HeaderChain implements the basic block header chain logic that is shared by core.BlockChain and light.LightChain. It is not usable in itself, only as a part of either structure. It is not thread safe either, the encapsulating chain structures should do the necessary mutex locking/unlocking.

func NewHeaderChain 

func NewHeaderChain(chainDb mandb.Database, config *params.ChainConfig, procInterrupt func() bool) (*HeaderChain, error)

NewHeaderChain creates a new HeaderChain structure. 

getValidator should return the parent's validator

func (*HeaderChain) HasHeader 

func (hc *HeaderChain) HasHeader(hash common.Hash, number uint64) bool

func (*HeaderChain) InsertHeaderChain 

func (hc *HeaderChain) InsertHeaderChain(chain []*types.Header, writeHeader WhCallback, start time.Time) (int, error)

InsertHeaderChain attempts to insert the given header chain in to the local chain, possibly creating a reorg. If an error is returned, it will return the index number of the failing header as well an error describing what went wrong.

The verify parameter can be used to fine tune whether nonce verification should be done or not. The reason behind the optional check is because some of the header retrieval mechanisms already need to verfy nonces, as well as because nonces can be verified sparsely, not needing to check each.

func (*HeaderChain) SetCurrentHeader 

func (hc *HeaderChain) SetCurrentHeader(head *types.Header)

func (*HeaderChain) WriteHeader 

func (hc *HeaderChain) WriteHeader(header *types.Header) (status WriteStatus, err error)

WriteHeader writes a header into the local chain, given that its parent is already known. If the total difficulty of the newly inserted header becomes greater than the current known TD, the canonical chain is re-routed.

Note: This method is not concurrent-safe with inserting blocks simultaneously into the chain, as side effects caused by reorganisations cannot be emulated without the real blocks. Hence, writing headers directly should only be done in two scenarios: pure-header mode of operation (light clients), or properly separated header/block phases (non-archive clients).

func (*HeaderChain) WriteTd 

func (hc *HeaderChain) WriteTd(hash common.Hash, number uint64, td *big.Int) error

WriteTd stores a block's total difficulty into the database, also caching it along the way.

type TxStatus 

type TxStatus uint

TxStatus is the current status of a transaction as seen by the pool. 

const (
	TxStatusUnknown TxStatus = iota
	TxStatusQueued
	TxStatusPending
	TxStatusIncluded
)

type TxpoolEx 

type TxpoolEx interface {
	DemoteUnexecutables()
	ListenUdp()
}

type Validator 

type Validator interface {
	// ValidateBody validates the given block's content.
	ValidateBody(block *types.Block) error
	// ValidateBody validates the given block's content.
	ValidateHeader(header *types.Header) error
	// ValidateState validates the given statedb and optionally the receipts and
	// gas used.
	//ValidateState(block, parent *types.Block, state *state.StateDBManage, receipts types.Receipts, usedGas uint64) error
	ValidateState(block, parent *types.Block, statedb *state.StateDBManage, usedGas uint64) error
}

Validator is an interface which defines the standard for block validation. It is only responsible for validating block contents, as the header validation is done by the specific consensus engines.

type WhCallback 

type WhCallback func(*types.Header) error

WhCallback is a callback function for inserting individual headers. A callback is used for two reasons: first, in a LightChain, status should be processed and light chain events sent, while in a BlockChain this is not necessary since chain events are sent after inserting blocks. Second, the header writes should be protected by the parent chain mutex individually.

type WriteStatus 

type WriteStatus byte

WriteStatus status of write 

const (
	NonStatTy WriteStatus = iota
	CanonStatTy
	SideStatTy
)
