> Permissionless (ZK) Registries

Rarimo provides a permissionless zero-knowledge identity protocol enabling privacy-preserving verification of identity attributes across blockchains.

Rarimo builds permissionless ZK Registry that redefines how identities, interactions, and social graphs are managed. Rarimo uses client-side proving to deliver a censorship-resistant identity backbone that respects user anonymity while preserving historical interactions and continuity of identity. The system enables proving identity attributes without revealing sensitive data through zero-knowledge proofs.

## Products

- [ZK Registry](https://thegrid.id/profiles/rarimo): ZK Registry functions as a ZK Rollup for on-chain registry of abstract statements, enabling users to prove system state without revealing statement details. The registry aggregates standardized statements for identity verification, reputation, and proof-of-attendance use cases. (Decentralised Identity, In Development)
- [ZK Passport](https://thegrid.id/profiles/rarimo): ZK Passport transforms biometric passports into unique, privacy-preserving digital identities through self-issuance. Users can verify uniqueness, humanity, citizenship, and age while maintaining privacy via zero-knowledge proofs. (Decentralised Identity, Live)
- [RariMe App](https://thegrid.id/profiles/rarimo): RariMe is a self-custody identity wallet for mobile devices that converts biometric passports into anonymous digital IDs. The app scans passports using phone cameras and NFC chips to enable privacy-preserving identity verification. (Wallet, Live)
- [ZK Reputation](https://thegrid.id/profiles/rarimo): ZK Reputation allows users to prove their reputation based on private relationships and interactions without exposing sensitive details. Using zero-knowledge proofs, users can verify their trustworthiness and standing in various communities while maintaining complete control over their privacy. (Decentralised Identity, In Development)
- [Freedom Tool](https://thegrid.id/profiles/rarimo): Freedom Tool is an open-source decentralized voting solution using zero-knowledge cryptography to enable transparent, privacy-preserving online voting on blockchain. It protects voters from tracking while enabling digital identity verification. (Developer Tooling, Live)
- [Rarimo ZK Rollup](https://thegrid.id/profiles/rarimo): Rarimo ZK Rollup is a Layer 2 blockchain solution that inherits security from Ethereum while providing scalability and privacy for identity applications. The rollup aggregates transactions off-chain and submits cryptographic proofs to the Ethereum mainnet, enabling efficient processing of ZK Registry data with reduced costs. (L2, Live, Main Product)
