zkDON

Author: Thomas Bonanni

This is a Proof of Concept for a Zero-Knowledge Decentralized Oracle Network.

OCR Implementation based on Chainlink Off-chain Reporting Protocol

Premise

Modern Oracles suffer from a plethora of security flaws. Some driven by Oracle architechture itself, but others driven by underlying blockchain implementation. The goal of our zkDON is to achieve the following properties:

1. MEV Resistant - Oracles that publish updates on Ethereum are subject to back-running attacks, where an adversary will position a liquidation transaction in the mempool immediately after the oracle update transaction, thus instantly liquidating a vault without contest. We want our Oracle Network to be resistant to these types of attacks.

2. Decentralized & Open Source - Oracles that are not decentralized become a central point of failure in the system and will be targeted by attackers. Closed source Oracles are also subject to trust-issues from their consumers on top of not being able to be publicly audited. The Oracle Client implementation must be open source for maximal resilience.
