Open source project (anonymous vote POC)

Unlike others, I started developing blockchain with Tendermint, not Ethereum and Bitcoin.
So I’m interested in tendermint and cosmos-sdk.
The first project developed a document authentication blockchain platform using tendermint ABCI.

I’m currently developing the anonymous voting project using cosmos-sdk. (POC)

Up to now, creating of the agenda and voting has been completed. (vote is just yes or no)

And, I’ll add anonymous func using zk-snark.
So, I am researching zk-snark library in go (
If you know a better library, please advise.

I hope you are interested in this project.
Thank you.
