I believe validity on the whole is a considerably ambiguous time period. On one hand, a node verifies a transaction utilizing an inventory of standards. If all the standards are met, the transaction is taken into account legitimate. One such criterion is: “For every enter, the referenced output should exist and can’t already be spent” (Antonopoulos, Mastering Bitcoin, p. 235). So if all of the inputs of the brand new transactions are UTXOs the criterion is checked.
On the similar time, when discussing the “51% assault,” Antonopoulos notes that “The extra confirmations elapse, the tougher it turns into to invalidate a transaction with a 51% assault.” This suggests {that a} transaction may be invalidated by way of a series reorganization.
So, from a miner’s viewpoint, the validity of a transaction is a binary property. Nonetheless, from the broader community’s perspective, it’s probabilistic.
