The problem Green Ledger solves

The core problem addressed by Green Ledger is the lack of transparency, accessibility, and accountability in managing and offsetting carbon footprints. Currently, tracking carbon emissions, especially for organizations and individuals, is often complicated and lacks a centralized, trustworthy system. Moreover, the process of offsetting these emissions—such as investing in eco-friendly projects or purchasing carbon credits—is not straightforward and can lack transparency, making it difficult for entities to verify the impact of their investments.

Here's how it addresses critical issues:

Transparent Carbon Footprint Tracking:

Green Ledger enables easy and transparent tracking of carbon emissions, providing organizations and individuals with a clear view of their environmental impact.

Efficient Carbon Offset Market:

It simplifies and streamlines the process of carbon offsetting by creating a decentralized marketplace where users can seamlessly buy and sell carbon offsets. For example a company can directly transact with farmer to plan trees on their behalf effectively reducing their carbon footprint without a need of middle men. This makes it easier for companies to meet their sustainability goals.

Automated Notifications:

Green Ledger's automated notification system helps organizations stay within their carbon emission limits, reducing the risk of regulatory violations and associated fines.

Challenges I ran into

We faced problem in deploying the smart contract to Filecoin calibration testnet.
Layer 2 Scaling Solutions: We are exploring layer 2 scaling solutions, such as sidechains and optimistic rollups, to offload some of the transaction processing from the Ethereum mainnet.
