iden3 is an ambitious, open-source project which enables a new blockchain-based model and identity platform over the public blockchain. A trailblazing, self-sovereign privacy protocol, iden3 provides decentralized architecture, privacy for the user data, scalability on public blockchain, usability improveness, and transparency. The platform is a next-generation private access control based on self-sovereign identity, designed for decentralized and trust-minimized environments. It also features the iden3 identity wallet application, an open reference for end-users to receive trusted claims and generate zkProofs for private access. It also allows direct communication with another identity.
Censorship-resistant Infrastructure: Features high degree of decentralization and a security profile.
Battle-tested Cryptography: Utilizes zk-SNARK, allowing any computational condition to be represented by an arithmetic circuit.
Practical Standards: A novel proof-query language that allows simple configuration of the type of identity claims required for private verification.
