"""Test blinding logic when change is dropped and we have only one other blinded input
|
|
|
|
Constructs a transaction with a sufficiently small change output that it
|
|
gets dropped, in which there is only one other blinded input. In the case
|
|
that we have no blinded inputs, we would need to add an OP_RETURN output
|
|
to the transaction, neccessitating special logic.
|
|
|
|
Check that this special logic still results in a correct transaction that
|
|
sends the money to the desired recipient (and that the recipient is able
|
|
to receive/spend the money).
