  • Liang Qiao thinks this is interesting:

What this means is that if you create several transactions in sequence and one of them does not get officially included in any blocks, all the subsequent transactions will be “stuck,” waiting for the missing nonce. A transaction can create an inadvertent “gap” in the nonce sequence because it is invalid or has insufficient gas. To get things moving again, you have to transmit a valid transaction with the missing nonce. You should be equally mindful that once a transaction with the “missing” nonce is validated by the network, all the broadcast transactions with subsequent nonces will incrementally become valid; it is not possible to “recall” a transaction!
