Question 1 5 pts Assume that transaction f14a is a valid transaction and in that transaction, A has been given 25 bitcoins. Given the following pool of unconfirmed transactions f3cd 3ba5 78a8 Inputs: af52(2) Outputs: C(3), D(2). B(1). A(10.5) Inputs: e4a4(2) Outputs: E(O.5) Inputs: bd7d(2) Outputs: A(O.5), E(O.5). F[O.5), D(14) Signed (A) Signed (F) Signed (D) a14f Sce6 af52 Inputs: Outputs: F(25) Inputs: e4a4(2) Outputs: F(O.5) Inputs: f14a(1) Outputs: B(8). A(17) Signed (F) Signed (F) Signed (A) e4a4 ac8 bd7d Inputs: f3cd(1) Outputs: DO.S). F(1), C(1.5) Inputs: bd7d(1) Outputs: A(0.5). E(O.4) Inputs: afs2(1) Outputs: C(1), D(3).E(3),B(1) Signed (C) Signed (B) Signed (B) One of the transactions is invalid. Why is it so? There are no input to the transaction The transaction isn't created by the rightful owner of the bitcoin The sum of the outputs isn't equal to the input It is a double-spent transaction
