Inspiration
Current green incentives are not strong enough, have too high of an upfront cost, or are hidden away in tax codes. We want to bring green incentives to everyday people in an easy-to-understand manner.
What it does
Our hack tracks a given climate index/dataset, ex. pollution levels in a nearby lake, and updates the NFT's metadata and royalties accordingly. As the pollution levels drop, the owner's royalties increase, earning more when they sell. The NFT also updates its image to give a visual representation of the index.
How we built it
3 parts, an oracle to query climate APIs and move the data on-chain, a modified NFT contract that live-updates based on data from the oracle smart contract, and a frontend that ties it all together.
Challenges we ran into
The oracle used near-cli in Github Actions. A lot of issues came up regarding syntax and issues with keys.
Accomplishments that we're proud of
We are proud of how far we came and how much we learned in this project. We are also proud of producing a product that can be demoed that we believe shows promise. We are proud of the idea itself, as its not something we have seen done in either web2 or web3 but we believe has the potential to do much more than we have prescribed in this project.
What we learned
We learned a lot about calling contract functions in React and about the different utilities of the near cli.
What's next for Biome Trees
Linking our NFTs with marketplaces to be sold off our site. Applying this concept to incentivize other desirable behavior such as volunteering and civic duties.
