**EIF update for the week :**

*   Resubmitted the project proposal with analysis of similar products existing and how’s carbon trace is different.
    
*   **Analysis** with similar products :
    
    1.  **Pachama** is a platform that employs satellite imagery and machine learning to measure and verify carbon offsets. It also focuses on carbon offsetting and uses technology to verify carbon credits. CarbonTrace, on the other hand, utilizes blockchain technology to establish a transparent and secure market for carbon credit trading.
        
    2.  **AirCarbon** is a carbon trading platform that uses blockchain technology for trading carbon credits. Unlike CarbonTrace, AirCarbon does not tokenize carbon credits into NFTs. CarbonTrace's unique feature of tokenizing carbon credits into NFTs creates a more transparent and secure market for carbon credit trading.
        
    3.  **CBL** Markets is a carbon and environmental commodity trading platform that utilizes blockchain technology. Unlike AirCarbon, CBL Markets does not tokenize carbon credits into NFTs. CarbonTrace's use of NFTs creates a more unique and innovative approach to carbon credit trading.
        
    4.  **Nori** is a carbon removal marketplace that enables individuals and companies to fund carbon removal projects. Unlike CarbonTrace, which focuses on carbon credit trading through NFTs, Nori focuses solely on carbon removal.
        
*   Exploring different NFT contracts and its implementation strategies.
    
*   Started working on the smart contract infrastructure.
    
*   Implementation of CarbonCredit NFT contract which includes the following functionalities :
    
    *   Mints a new Carbon Credit NFT with the provided hashed unique ID and metadata.
        
    *   Marks a Carbon Credit NFT as used.
        
    *   Verifies if a hashed unique ID matches the expected hash for a given token ID.
