🌍 What is ZK Infinita Carbon?
ZK Infinita Carbon is a fully decentralized, on-chain carbon credit system that empowers individuals, DAOs, and communities to prove, verify, and trade their environmental impact — all without exposing sensitive data.
Built with zero-knowledge proofs, smart contracts, and IPFS, the platform brings together climate finance, decentralized governance, and Web3 privacy infrastructure to build sustainable economies inside Network States and digitally native communities.
Designed specifically for the Crypto Cities Hackathon, this project redefines how we certify and exchange environmental value — making carbon accountability transparent, programmable, and privacy-respecting.
