I led the ZKBugsBounty project during the Blockchain Academy course and have won the 1st place out of 6 projects. The project is about managing Bug-Bounty process on the Ethereum Blockchain with Smart Contract and Zero-Knowledge proof. Proof of knowledge about a sensitive bug without revealing any data about the bug. Using ZoKrates (a zkSNARKs framework) on Ethereum blockchain The Zero-Knowledge part is when the vendor has to prove to the security-researcher that they already know the security bug the researcher found without the vendor knows anything about the bug! https://youtu.be/klfTxlCFfks]]>
