The Vision for JudgeNod

JudgeNod was born from a simple observation: hackathon winners are often decided behind closed doors, with no public record of the evaluation process or technical scoring.

Why Verifiability Matters

In the Web3 ecosystem, trust is code. As hackathons grow to offer millions in prizes, the integrity of the judging process becomes a primary security concern. JudgeNod provides a trustless infrastructure that ensures:

Immutable Scoring: Once a judge submits a score, it is cryptographically signed and recorded on the Solana blockchain.
Transparent Logic: Scoring rubrics are defined in smart contracts, preventing "last-minute" changes to the rules.
Public Auditability: Anyone can verify that the final leaderboard matches the sum of individual judge inputs.

JudgeNod currently supports Solana Mainnet and Devnet, with future support planned for other high-throughput SVM-based chains.

How it Works

The JudgeNod workflow is designed to be invisible to judges while being rigorous for organizers. Judges interact with a familiar UI or CLI, while the backend handles the complex task of repo analysis and on-chain submission.
