為什麼我會收到“從池中移除 tx：低 tx 隨機數或資金不足”？

我用來送出交易的賬戶有 10490 ETH (1.0585e+22 Wei)。交易成本為 20477 Gas，Gas 價格為 300000000000。

下面是 Geth 的輸出：

產生此錯誤的原始碼位來自https://github.com/ethereum/go-ethereum/blob/4044a8cea44cd4cee3a8ddaf51a76b71c9d22042/core/tx_pool.go#L489-L502並在函式 tx_pool.go:validate_pool( …）。

...
if past := state.GetNonce(sender) > tx.Nonce(); past || balance.Cmp(tx.Cost()) < 0 {
   // Remove an already past it invalidated transaction
   if glog.V(logger.Core) {
       glog.Infof("removed tx (%v) from pool: low tx nonce or out of funds\n", tx)
   }
   delete(pool.pending, hash)
   ...

正如您所說，您的帳戶中有足夠的餘額，由於檢查了交易隨機數，該交易必須已被拒絕。在您發布的數據中，您的交易 nonce 為 7。必須已經有來自同一個帳戶的先前交易，其中已經使用了 7 或以上的 nonce。
