RBF (Full RBF, Decide-in Full RBF, FSS-RBF) is utilized to a transaction when certainly one of its inputs “matches” one of many inputs within the alternative transaction.

Nonetheless, what occurs if the inputs of a alternative transaction “hit” the inputs of two (three or extra) totally different transactions?

  1. Does the alternative transaction then change all these “hit” transactions (transactions lined by alternative)?

  2. To ensure that alternative to happen, does the price of alternative transaction should be better than the biggest price amongst all “lined” transactions, or maybe the price of alternative transaction should be better than the sum of the charges of all “lined” transactions (or one thing else)?

  3. What would occur if the node works in Decide-in Full RBF mode and among the transactions “included” in alternative don’t settle for the potential of alternative (nSequence of all inputs is 0xffffffff)? I assume that the alternative then won’t even happen and the alternative transaction will likely be simply rejected.
