During the Hackathon, Chatafisha developed a Carbon-backed NFT marketplace that combines blockchain technology with sustainability efforts to create a transparent and verifiable impact measurement system. Our core innovation lies in our carbon-backed NFTs created which act as "Impact certificates", offering a tangible way to represent and reward ecological contributions. Beyond this, Chatafisha is developing an attestation framework and impact calculator to standardize impact metrics across various sectors. These tools aim to revolutionize how impact is assessed and verified, providing scalable and adaptable solutions for driving positive change.
