Nomad announces $190 million bounty for lost funds from recent hack

Nomad announced that it’s offering up to a 10% bounty to return funds stolen from the recent hack on the Nomad bridge on Aug. 2.

How do I calculate number of multiplication, exponential, and pairing operations in a cryptographic algorithm (signcryption/unsigncryption)?

I have been working on signcryption scheme and its security proof. I want to compute the efficiency in terms of number of scalar multiplication operation, number of exponential operations, and number of bilinear pairing operation. I am comparing it with other schemes as well. I think I am missing out some information regarding point scalar::Listen

I have been working on signcryption scheme and its security proof. I want to compute the efficiency in terms of number of scalar multiplication operation, number of exponential operations, and number of bilinear pairing operation. I am comparing it with other schemes as well. I think I am missing out some information regarding point scalar multiplication and couldn’t figure how should I count the number of multiplication operation. For example if Usigncryption step in the figure below, I see only 2 multiplication operations U1=r1P2 and U2=r1QA. Is it correct?
