Inspiration

Ecoxchange was inspired by the growing need to support renewable energy and the trading of environmental credits. We recognized that Renewable Energy Certificates (RECs) and carbon offsets, though critical to combating climate change, are often more valuable monetarily than the actions they represent. By creating a platform that makes the buying and selling of these certificates easier and more transparent, ecoxchange allows businesses to reduce taxes and fund future green investments while promoting environmental responsibility.

What it does

Ecoxchange is a platform that enables users to trade renewable energy certificates and environmental offset credits. Sellers can upload their certificates, which are automatically validated and classified using machine learning. Buyers can search for and purchase these certificates to offset their carbon footprints or meet sustainability goals. The platform ensures that all documents are genuine by using statistical validation methods and cosine similarity to compare uploaded certificates to a database of verified documents. This ensures that only valid and authentic certificates are traded, providing peace of mind to buyers and sellers alike.

How we built it

Ecoxchange was built using a full-stack approach, combining modern web technologies with robust backend services:

Frontend: We built the user interface using React and Next.js to provide a responsive, dynamic experience for both buyers and sellers. Backend: The server-side logic was handled by Node.js and Express.js, with a MongoDB database managing the storage of certificate data. Document Handling: PyMuPDF was used to read and extract data from the certificates uploaded by sellers, ensuring accurate data capture from non-digital formats. Machine Learning: We integrated Cerebras AI to classify and evaluate the certificates based on their content and market value. Authentication: Propel Auth was used to secure the platform, ensuring only authorized users could buy and sell certificates. Document Validation: We employed a statistics-based approach combined with cosine similarity to validate that uploaded documents matched known valid formats and structures. By comparing the content of uploaded documents with existing records, we ensured authenticity before listing them for sale. Hosting: The entire platform was deployed on Vercel, ensuring seamless scalability and performance.

Challenges we ran into

Authentication: Implementing secure user authentication with Propel Auth presented challenges, particularly around managing user roles and permissions for buyers and sellers. File Reading: Extracting accurate data from a variety of document formats using PyMuPDF was more complex than anticipated, especially for non-standard formats. Next.js Router: We encountered difficulties with Next.js' routing system, especially when managing dynamic routes for different user flows (such as uploading, searching, and purchasing certificates). Accomplishments that we're proud of Polished User Interface: We are proud of the clean and intuitive interface that makes it easy for users to navigate, upload documents, and complete transactions. Functional MVP: Despite the challenges, we successfully built a fully functional MVP that processes document uploads, validates them, and enables users to buy and sell certificates with confidence.

What we learned

Throughout the development of ecoxchange, we learned a great deal about the challenges of building a platform that handles both sensitive data and financial transactions. We gained experience in integrating machine learning models for real-time document classification, improving our understanding of web security through Propel Auth, and mastering document handling through PyMuPDF. Additionally, we learned the importance of ensuring that data validation processes are robust to maintain trust in the marketplace.

What's next for ecoxchange

Blockchain?: We are considering integrating blockchain technology to provide immutable verification of certificates and transactions, adding an extra layer of trust and transparency. Enhanced Analytics: Expanding our data analytics capabilities to offer better insights into certificate valuations and market trends for both buyers and sellers. Expanded Certificate Support: We plan to support additional types of environmental credits, making ecoxchange a more comprehensive marketplace for sustainability efforts.
