An example of a zero-knowledge encryption use case whereby computations get delegated to the server and the client just has to verify the received proof.

Presently, the server flips a PNG image upside down upon the user's request and sends a proof of Involution that can be validated within the browser.

To set up the InvolutionZKP project, you'll need to have the following tools installed:

• Node.js
• NPM (Node Package Manager)
• Rust
• Circom

1. Clone the repository and navigate to the project root directory:

git clone https://github.com/SFYLL/InvolutionZKP.git
cd InvolutionZKP

2. Install the required dependencies:

npm install

3. Run the project

./run.sh

Pull requests are welcome. Please make sure to update tests as appropriate. If you want to play around with this project, here are some leads:

• Optimize the circuits so that it can run on higher definition PNGs;
• Increase the circuit modularity, allowing users to define their own involutive functions;
• Implement recursive ZK-proofs. That way, as you bundle involutive functions together the complexity of reverse engineering each function grows exponentially.
