Obfustopia Deobfuscator

This deobfuscator is designed to break the obfuscation implemented in gausslabs/obfustopia.

Learn more about the challenge and its resolution from the article:
Breaking the $10,000 iO Bounty: My Journey to Crack an Indistinguishability Obfuscation Implementation

Installation

Install dependencies:

npm ci

Usage

Run the deobfuscator with the following command:

npm run optimize data/latest.json data/obfuscated.json

This will read circuit data/latest.json in. If the file does not exist, it copies the data\obfuscated.json to its place and starts to operate.

The process creates a checkpoint file periodically and also saves the most recent version to the data/latest.json. You can exit from the program and run the command again to restart. The optimizer runs forever, so you need to exit from program with "ctrl c".
