Replying to [comment:3 vinay]:
> * MTP 1.2 (https://arxiv.org/pdf/1606.03588.pdf)
Unfortunately, we only have about 253 bytes max to use if we want to send
the proof in the intro circuit itself... MTP proofs are ~187KB with their
recommended L=70 parameter (see Section 4.6). This is far too large to use
without a secondary validator server that hands out tokens in exchange for
proofs, which is a lot more complexity :/
Other potential ideas from the MTP paper's references:
* https://wwwcn.cs.uni-
duesseldorf.de/publications/publications/library/Jerschow2010a.pdf
* https://eprint.iacr.org/2017/1168.pdf (has a good comparison section at
the end)
