My course teacher mentioned that the two forking lemmas have different prerequisites for use. The former article (Security Arguments for Digital Signatures and Blind Signature) is more limited, but I did not find it in the second article I read, and the article did not describe the difference between the two in detail (for example, the article mentioned that article 1 is not applicable to multi-signature).
I am not a student of cryptography, so I can't easily understand this problem. Maybe I didn’t understand the article, but I hope to get your answers, thank you!
