Oh boy. People smarter than me (hopefully?) have done some work to explain some of what I have been yammering on about in the speculation thread for, well, quite a bit...
Thanks for posting. I hope it's not bunk. let's see!
This was excellent analysis! And very interesting... I will be pondering it's meaning for a while.
Although they call the event an "attack" at one point in the piece they never speculate as to motive.
One motive I can think of is creating a sybil attack for future decoys? A database of ring members to be used in de anonymizing attempts later? Which also justifies the ~1k cost incurred in fees?
To be honest this is hitting the boundaries of my "How does Monero work" knowledge...
Just assuming that WAS the motive, i wonder if there are any countermeasures that do not introduce more attack surface.
VERY INTERESTING STUFF!
