接上文,在这个函数中
func (sm *SyncManager) handleTxMsg(tmsg *txMsg)
调用txMemPool成员函数ProcessTransaction对tx进行校验。在syncmanager对象中,txMemPool,顾名思义就是交易池。负责对交易的验证和管理。
tx的数据结构如下:
// Tx defines a bitcoin transaction that provides easier and more efficient // manipulation of raw transactions. It also memoizes the hash for the // transaction on its first access so subsequent accesses don‘t have to repeat // the relatively expensive hashing operations. type Tx struct { msgTx *wire.MsgTx // Underlying MsgTx txHash *chainhash.Hash // Cached transaction hash txHashWitness *chainhash.Hash // Cached transaction witness hash txHasWitness *bool // If the transaction has witness data txIndex int // Position within a block or TxIndexUnknown }
在ProcessTransaction函数中调用了maybeAcceptTransaction,其中CheckTransactionSanity,主要对交易的输入个数和及交易的序列化大小、交易输入的前向节点,交易输出的比特币大小进行验证
