Humanity Protocol is a decentralized identity system that enables users to verify their unique human identity through non-invasive palm scans, ensuring privacy via zero-knowledge proofs. Built on a zkEVM Layer-2 blockchain using Polygon's Chain Development Kit, it employs a Proof-of-Humanity consensus mechanism to resist Sybil attacks. The protocol allows users to maintain self-sovereign identities, facilitating applications like secure dApp logins, on-chain reputation systems, and fair token distributions.
