Project Introduction
NodeScope is a read-only node-health and fee diagnostics toolkit for Portaldot V3 operators and validators.
It turns RPC checks into an explainable health score, concrete next steps, and exportable diagnostic reports. No wallet is required for diagnostics, and NodeScope never signs transactions or holds private keys.
Problem Solved
An endpoint responding once does not tell an operator whether it is progressing, finalizing, or returning consistent results across EVM and Substrate interfaces.
NodeScope brings these checks together, explains which components need attention, and helps operators compare observations over time. Its Fee Lab also separates transaction fees from refundable storage deposits, making EVM-versus-native cost comparisons easier to interpret.

Technical Highlights
1. Explainable Health Score
The published scoring formula combines RPC availability, chain identity, head progression, finality lag, latency, transport parity, peers, synchronization, and reliability. Component-level results explain the total; unavailable inputs are not silently treated as healthy.
2. Portaldot-specific diagnostics
EVM and Substrate heights are compared with a two-block tolerance, and persistent discrepancies produce operator guidance. Requests are paced below five per second per endpoint.
3. Actionable monitoring
Results include suggested next steps rather than just a red or green indicator. Browser-local seven-day baselines, score history, multi-node views, and Prometheus support help operators spot changes and integrate diagnostics into their workflow.
4. Fee Lab
Side-by-side EVM and native estimates distinguish fee-only costs from all-in costs, showing refundable storage deposits separately. Diagnostics do not submit transactions.
5. Verifiable reports
Exported diagnostic reports can be checked using SHA-256 verification. These reports document observations at a particular time; a health score is not proof of node correctness or certification of the entire network.

Judges & Voting Fit
For Judges: NodeScope is a working, open-source tool built around Portaldot V3’s EVM and Substrate interfaces. Try a health check, inspect its component scores and recommendations, then export a report and verify it. The repository includes automated tests and CI workflows.
For Community Voters: NodeScope helps operators answer practical questions: Is my endpoint healthy? What needs attention? How do fees compare when deposits are counted separately?
