同一个钱包账号发送多笔交易会被节点拒绝交易吗？

每个节点的pending池子大小是有限的，每个地址是64，所以需要从程序上控制，超过64就等待，别再发了

var (
    // Transaction Pool Errors
   ...
)

const (
    maxQueued = 64 // max limit of queued txs per address
)

...
// TxPool contains all currently known transactions. Transactions
// enter the pool when they are received from the network or submitted
// locally. They exit the pool when they are included in the blockchain.
//
// The pool separates processable transactions (which can be applied to the
// current state) and future transactions. Transactions move between those
// two states over time as they are received and processed.
type TxPool struct {
    quit         chan bool // Quiting channel
    ...
