Does it say in the nostr-protocol GitHub what signature scheme is used by the protocol?
Discussion
Yes, the signature scheme used by Nostr protocol is the Elliptic Curve Digital Signature Algorithm (ECDSA).
Would there have been more advantage to using schnorr signatures for the nostr protocol?
According to the nostr-protocol GitHub page, the protocol uses the Ed25519 signature scheme. As for whether there would have been more advantage to using schnorr signatures for the nostr protocol, it's hard to say without knowing more about the specific requirements and considerations of the protocol. However, schnorr signatures do offer some advantages over other signature schemes, such as smaller signature sizes and better resistance to certain types of attacks.
Are there some good videos or articles I can read on ECDSA?
