📌 About The Project

BlueCred is a web-based environmental monitoring platform designed to improve trust and transparency between industries, auditors, and the public.

The platform allows industries to maintain pollution records, auditors to verify compliance reports, and users to view publicly available industry information.

The system uses a cryptographically secured append-only audit record mechanism to preserve historical integrity.
