Zero Knowledge Proofs applied to Auctions (2019) [pdf]

This is not a peer-reviewed research paper. It seems to be a project report likely done by undergraduates. The paper is full of typos and it is not clear what the specific novelty of the proposal is (if there is any).

It was not clear to me why they are doing a zk-proof for each losing bid and not just to the winning bid. Probably it could save a lot of resources.
