Hello all! Is TXID predictable before transaction broadcast to peers? Or in other words,can someone choose a certain txid he want when broadcast a transaction?
The answer to the second question is no. Furthermore that would be an undesirable feature of a hash function. See "preimage attack".
So we can still have a hash set to choose from by select different vin or nLockTime without ruin a transaction.
