Beastieland is the first animal NFT collection responding to global environmental changes 🐼 Built with #SmartWeave Contracts, Beasties die out with negative climate trends and have offspring with positive ones - creating an emotional bond to human impact on the environment 🌎
Beastieland is a dApp aiming to create emotional feedback to the climate changes caused by human activities 🌎 By creating an interactive animal NFT collection that responds to the global temperature a viewer can feel the effects of human actions on living species. Emotions are the key component for an individual to associate with the cause and take action. So with Beastieland, instead of seeing a raw number of CO2 emissions, you experience the consequences from the perspective of animal species 🐘 To keep environmental friendliness, we use Arweave blockchain, which relies on emission neutral Proof of Access, to store NFTs and SmartWeave Contracts for dApp execution. As the first iteration of the dApp we created a collection of 5 animal NFTs: Panda, Lion, Elephant, Fox and Zebra. Global temperature changes are considered to be one of the key global climate factors, so we chose this metric as background for animals reactions. Some of them are more resistant, while some more vulnerable to temperatures swings 🌡️ We've implemented a mock oracle contract for the hackathon purposes so that our app users can change the temperature value and see the impact of that change. However, in the next iteration of the Beastieland, we will connect our NFT contract to the real blockchain oracle with the real climate values. We will also connect more types of data that can influence animals: CO2 emissions, deforestation, ozone layer depletion, etc. Our NFT SmartWeave contract has an innovative way of calculating tokens metadata. On each call of the "getAllTokens" query function, it fetches the latest temperature value from the oracle contract. This value is used to dynamically calculate corresponding attributes and images for each NFT token. Currently, NFT images may present an animal, an animal with offspring, or a ghost. Initially, all the animals are safe and sound, but when the temperature is below a specific threshold, an animal dies and becomes a ghost. Thankfully, when the temperature rises above that threshold, the conditions are again hospitable and an animal comes back to life. Moreover, when the temperature gets to an animal-friendly level, the offspring appears! We wanted to emphasise that the results of human activity are reversible and it's up to our decisions if we make a change or not ✅ If such NFT collection would generate revenue, a portion of it would be transferred to organisations fighting for positive climate impact or supporting directly endeared species.
