This is a port in the arkwork framework of the original implementation in bellperson of Snarkpack. Note both works are derived from the original arkwork implementation of the inner pairing product argument (IPP) paper.
Add the following to your Cargo.toml
snarkpack = { git = "https://github.com/nikkolasg/snarpack" }
See the straightforward example in tests/aggregation.rs.
There are plenty of issues to tackle so you're more than welcome to contribute.
