FarmerNet NFTs


Carbon emission information is siloed, non-verified and non-standardized. The goal is to reduce environmental impacts and carbon footprint, and increase progress towards global and corporate carbon emission goals while helping struggling farmers with FARMERNET.

Blockchain Social Impact Solution

  • Changing the ways of old by disrupting the entire framework of how we manage our carbon emission information.
  • Enables stakeholders to track, trace, match and manage their clean energy footprint while simplifying data-driven attestation of sustainability goals and mandates.
  • Proof and immutability for the real world impact of carbon emission generation and consumption - allows companies to stand behind their claims of carbon reductions, sustainability, and renewable energy to prevent greenwashing using the immutable ledger to track environmental assets and liabilities.
  • Farmernet’s smart contract’s logic and data trigger are viewable on the blockchain by all stakeholders, leading to transparency and independent verification of all outcomes.
  • Tamperproof execution and data delivery to carbon emission, to avoid double-counting resulting in producers and consumers being able to trust that they will get the land based on accurate data metrics.

Non Fungible Tokens NFTs

Non fungible tokens: Dynamic and changes based on real world data metrics land-based carbon emission NFT on the Rinkeby Chain:

  • ERC721 tokens
  • Metadata provides descriptive information for a tokenId that is stored off-chain
    • This will create a land NFT with 4 attributes:
    • uint256 longitude coordinate;
    • uint256 latitude coordinate;
    • uint256 carbon sequestered per land;
    • string name of land NFT;
  • Each tokenId has a specific tokenURI that defines this API call, which returns a JSON object that looks something like this
  • Assign tokenIds to their tokenURI, NFT marketplaces will be able to display your token -Image is using a URL that points to IPFS InterPlanetary File System -Every time the image is updated, the on-chain hash/tokenURI also has to change, meaning that we can have a record of the history of the metadata
  • OpenSea NFT marketplace

How it works

  • Build a verifiably dynamic land-based aerial image using Chainlink
  • Assignment of statistics and resources - name and attributes from your deployed token
  • Rinkeby Testnet ETH and Rinkeby Testnet LINK
  • Add a tokenURI using IPFS - makes it easier to store things like images since we don't have to waste the gas of adding them on-chain.
  • Store images in peer-to-peer file storage system IPFS and pin the data with Pinata for when IPFS node is down
  • Deployed dynamic NFT to the OpenSea marketplace - Allows users to smoothly buy and sell NFTs, get custom stats and analytics, and earn revenue when items get traded.

Future Work

  • Include other protocols not just Rinksy testnet – like mainnet
  • Building a user-friendly front-end for farmers to interact with with UI UX design
  • Integrating with blockchain Metamask wallet payments
  • Proving who owns what at what time – Solana
  • Gas-efficient code - check ETH demand on the network and use Layer-2 networks - Matic
  • Better encryption
  • Defi payment options Aave, O(1) Labs, or Compound
