Carbon emission information is siloed, not-verified and non-standardized. The goal is to reduce environmental impacts and carbon footprint, and increase progress towards global and corporate carbon emission goals with FARMERNET - a proof of concept in 36 hours to test the idea and gather feedback as to whether this idea can truly help combat climate change.
Non fungible tokens: Dynamic and changes based on real world data metrics land-based carbon emission NFT on the Rinkeby 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;
Deployed dynamic NFT to the OpenSea marketplace - Allows users to smoothly buy and sell your items, get custom stats and analytics, and earn revenue when your items get traded.
How it's built
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
Adding NFTs to the OpenSea Marketplace
Metadata provides descriptive information for a tokenId that is stored off-chain
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
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 defi payment systems – Metamask wallet payments
Proving who owns what at what time – Solana
