What they do

Problem

Web3 lacks a way to verify unique human users and aggregate identity credentials without sacrificing privacy, enabling Sybil attacks and unsafe DeFi/governance/airdrop participation.

Solution

Notebook uses zero-knowledge proofs to create a one-person-one-account identity that enables anonymous proof-of-humanity and cross-wallet credential aggregation without revealing personal information.

Who it's for

Web3 protocols and communities such as DeFi platforms, DAOs, and airdrop creators who need Sybil-resistant human verification and credential-based access.
