waxwing (npub1vad…nuu7)
can i ask you to take a look at this as well?

i have been meaning to ask an opinion on this (second) DLEQ from someone:
https://github.com/moonsettler/cashu/blob/dleq-por/docs/specs/40.md#alice-requests-dleq-proof-on-c

the idea is that the first DLEQ only proves that k private key was used to create C signature, if the r blinding factor is revealed because normally it only proves the relationship between B' and C'. this second DLEQ however is supposed to be a publicly verifiable proof that a token was signed by Bob without breaking unlinkability.
