Rarimo

Rarimo is a privacy-first social protocol that enables users to interact anonymously while preserving their reputation and social history. Its core infrastructure is the ZK Registry, a permissionless ZK Rollup built on the ERC-7812 standard, which stores abstract statements without revealing personal data. Key products include ZK Passport, which converts biometric passports into anonymous digital identities via client-side proving; ZK Graph, which allows users to prove reputation based on private interactions; and Bionetta, a ZKML framework for private inference. The protocol addresses a fundamental market pain point: existing social systems force users to choose between publicity (with reputation) and anonymity (without credibility). Rarimo combines both by letting users selectively disclose verified statements—e.g., proving age over 18 without revealing a birthdate—while keeping the underlying social graph private and immune to OSINT or AI analysis. Over the past six months, the project has focused on maturing its ZK Registry infrastructure, advancing the ZK Graph reputation module for early adopters, and refining the Rarimo App for document scanning and QR-based proof presentation. The Freedom Tool, a privacy-preserving voting solution, has also seen continued development. Challenges remain: proving schemes need better efficiency for mobile devices, account recovery across devices is complex due to locally stored data, and computations over encrypted social graphs are still being optimized. No major security breaches or outages have been reported in the period.
