Blockchain/Platform:

• Ethereum/EVM (Base Sepolia Testnet)

Description

What does this contribution do?

This contribution adds JuryDAO, a decentralized governance framework that replaces traditional token-based voting with provably random juries for each proposal.
It demonstrates how to use Pyth Entropy VRF for transparent and verifiable randomness in smart contract governance.

How does it integrate with Pyth?

• JuryDAO requests randomness from Pyth Entropy whenever a proposal is created.
• The callback function entropyCallback() receives the random number.
• It then performs a Fisher–Yates shuffle to select jurors fairly and without bias.
• The selection is logged on-chain for transparency.

What problem does it solve or demonstrate?

It showcases a practical governance application using verifiable randomness to combat:

• Whale dominance in DAO voting
• Low participation and voter fatigue
• Lack of fairness and scalability in traditional DAOs

Notes for Reviewers

This example demonstrates a complete DAO governance model powered by Pyth Entropy randomness.
It’s a solo hackathon project built by a developer from IIT Roorkee, and aims to showcase real-world governance improvements using decentralized randomness.
