We have never received grant money specifically designated for the development of Proof of Innocence. Grants that we have received were for integrating Proof of Innocence into preexisting protocols. For instance, we received a grant from Railgun to incorporate Proof of Innocence into their proving system and a grant from MolochDao to incorporate Proof of Innocence into privacy pools to facilitate arbitrary transaction amounts. These grants were not exclusively for working on Proof of Innocence as an independent project.
