11:34:05 <maybefbi> to reconstruct the challenge for verifying an MLSAG signature, i need all key images including the key image for the commitment-to-zero. so am i right in assuming the key image of commitment-to-zero is only ignored when linking two MLSAG signatures in monero?
11:42:44 <sarang> MLSAG doesn't use an image for the amount commitment component
11:53:26 <maybefbi> you are right, i checked Z2M2 again and the key images only correspond to one time addresses and their private keys. are we using the private key for commitment-to-zero anywhere? how do we prove to the onlookers i know the difference of blinding factors between the commitment and the pseudo commitment?
11:58:02 <maybefbi> never mind i see it now
11:58:27 <maybefbi> K_(i,m) is the difference between commitments
11:59:34 <maybefbi> when m>1
11:59:42 <maybefbi> but wait we dont have to know the difference between blinding factors to sign?
11:59:46 <sarang> Note that CLSAG does include such an auxiliary key image, but it is not used for linking purposes
11:59:57 <sarang> Yes you do need to know
12:00:10 <maybefbi> what for?
12:00:41 <sarang> What is your question referring to
12:01:33 <maybefbi> im trying to combine sections 3.5 and 6.2.2 in Z2M2
12:02:09 <maybefbi> im trying to make sense how we are proving to the world that i know the difference between the blinding factors
12:52:11 <gingeropolous> what ever happened to the university thing with monero research lab, sarang , suraeNoether ? Like one of you was working on an entity or something.
12:55:57 <sarang> maybefbi: you're showing that you know the base-`G` logarithm of the difference between the amount commitment and a commitment offset to the same value
12:56:35 <sarang> and then you construct the blinding factors of the offsets and newly-generated amounts to sum to zero
12:56:38 <sarang> this shows balance
12:56:42 <sarang> in a signer-ambiguous way
12:57:17 <sarang> gingeropolous: suraeNoether and others are collaborating with Clemson University to have a student work on a Monero-related project TBD
12:58:12 <gingeropolous> yeah but i thought u created a .... thing or something. it was like Magical something.
12:58:55 <sarang> suraeNoether spearheaded a grant organization, MAGIC
12:59:07 <sarang> He has since passed leadership on to others, but you'd have to ask him for details
13:00:13 <gingeropolous> but thats cool too. i was just answering this : https://old.reddit.com/r/Monero/comments/j02og5/if_someone_donated_5_million_to_monero_how_could/?ref=share&ref_source=link
13:00:17 <gingeropolous> ah yes, MAGIC, that was it
13:28:45 <maybefbi> sarang: thanks. let me try writing some code, i will better understand what you said.
