About Rarimo

Rarimo is a permissionless zero-knowledge (ZK) registry and rollup redefining how identities, interactions, and social graphs are managed. It enables developers to build privacy-preserving applications using tools like ZK Passport, ZK Graph, and ZKML Bionetta.

zero-knowledge identity privacy

Rarimo is a decentralized protocol revolutionizing the way digital identity is managed, shared, and verified across Web3 ecosystems. Unlike traditional identity systems that rely on centralized issuers or custodians, Rarimo leverages zero-knowledge cryptography and client-side proof generation to ensure that users maintain full control over their data while proving essential credentials or behaviors.

From seedless crypto wallet recovery to anonymous passport-based voting, Rarimo delivers modular identity tools that serve developers and users alike. These tools are designed to be censorship-resistant, interoperable, and developer-friendly. By building on top of ERC-7812 and deploying on a dedicated ZK Rollup, Rarimo ensures a scalable and private digital identity layer that aligns with the values of decentralization, privacy, and user sovereignty.

Rarimo is developing a comprehensive, open, and privacy-preserving identity protocol rooted in zero-knowledge proofs (ZKPs). At its core is the ZK Registry, a permissionless infrastructure that enables anyone to generate, register, and verify abstract identity-related statements—without revealing personal information. Unlike universal identity models that aim to bind people to static profiles, Rarimo supports a pluralistic vision, where individuals can maintain multiple verified identities depending on context, purpose, or community.

To power this system, Rarimo deploys its ZK Registry on a custom ZK Rollup, ensuring scalability and low costs while inheriting security from the Ethereum network. This rollup allows developers to create identities, proofs, and attestations that remain provable across multiple blockchains. Key components of the Rarimo ecosystem include the ZK Passport—which transforms biometric passports into self-sovereign credentials—and Bionetta, a ZKML-based framework for privacy-preserving face recognition. Additionally, the ZK Graph allows users to prove trust, reputation, and credibility across private interactions without exposing any relationships.

Rarimo’s ecosystem is already powering groundbreaking applications, such as Freedom Tool—an anonymous voting app used by activist groups and civil movements worldwide, RariMe—a self-recoverable crypto wallet, and Openion—a social platform enabling pseudonymous opinion markets. These tools are all built with privacy-first design and client-side proof generation, ensuring maximum security and minimum data exposure.

With backing from prominent figures like Vitalik Buterin, Nick White (Celestia), and co-founders of Aztec, Gnosis, and Aleo, Rarimo is positioned as a critical infrastructure layer for the future of Web3 identity. Its approach also contrasts with projects like Worldcoin by prioritizing user privacy and eliminating reliance on biometrics stored or processed by centralized servers. Similar platforms in the decentralized identity space include Proof of Humanity, Polygon ID, and Civic, though Rarimo stands apart with its open-source zk-native infrastructure and client-side architecture.

Rarimo provides numerous benefits and features for developers, organizations, and individuals building within the decentralized identity space:

Zero-Knowledge Privacy: All identity proofs are generated using zk-SNARKs, allowing users to prove facts without revealing underlying data.
Client-Side Proof Generation: No server-side processing of biometrics or personal data—everything is generated on the user’s device, preserving full autonomy.
Seedless Wallet Recovery: Use image-based cryptographic recovery tools through RariMe, eliminating the need for traditional seed phrases.
ZK Passport Integration: Turn any NFC-enabled physical passport into a privacy-preserving digital credential without uploading or exposing any document data.
Modular Identity Tools: Easily integrate ZK Registry, Bionetta for ZKML facial verification, and ZK Graph for provable social reputation into your app.
Open-Source and Extensible: Built on ERC-7812, Rarimo encourages community adoption and application-specific registries, supporting developers globally.
Real-World Impact: Tools like Freedom Tool have already been used for political voting and civil action in countries like Georgia and Russia.

Rarimo FAQ

Rarimo implements zero-knowledge cryptography (ZKPs) to allow users to prove facts about themselves—such as identity, credentials, or reputation—without revealing any sensitive data. Every proof is generated locally on the user’s device, ensuring full control and data privacy. Instead of exposing biometric information, Rarimo converts it into hashed vectors and mathematical proofs. This privacy-first architecture makes Rarimo one of the few systems capable of enabling verifiable identities with absolute anonymity.
The ZK Passport on Rarimo transforms traditional biometric passports into privacy-preserving digital credentials. Unlike centralized identity systems that upload personal data to servers, the ZK Passport uses NFC chip scans that never leave the device. Only a zero-knowledge proof is shared onchain. This approach allows users to verify their real-world identity without exposing names, photos, or nationality—creating a secure, compliant, and anonymous identification framework for Web3 apps.
Yes. The ZK Registry protocol from Rarimo is fully open-source and built to support extensibility under the ERC-7812 standard. Developers can deploy permissionless registries or integrate privacy features like Bionetta for ZKML image verification and ZK Graph for anonymous social reputation. With this modular toolkit, Rarimo makes it simple to build decentralized apps for voting, reputation scoring, KYC, or even gaming—all with zero data exposure.
Through its innovative seedless recovery protocol, Rarimo allows users to recover access to their crypto wallets without traditional seed phrases or backups. Using encrypted on-device image recognition and zk-ML proofs, Rarimo binds wallet recovery to a cryptographic image that only the user controls. No external server or cloud is involved, meaning no personal data can be leaked or stolen. This solution, available through RariMe, offers true self-custody without the vulnerabilities of password or seed storage.
Rarimo’s privacy tools are already transforming digital governance and civic engagement. Applications like Freedom Tool enable anonymous voting verified through ZK Passports, empowering citizens to participate in elections or referendums without surveillance. For instance, Rarimo has powered political voting apps in Georgia and supported civil initiatives in Russia through censorship-resistant, blockchain-based ballots. These implementations demonstrate how Rarimo can merge cryptography, privacy, and social impact in the real world.
