what's Rarimo?

Rarimo is a permissionless zero-knowledge (ZK) registries protocol that enables cross-chain messaging of digital assets and proofs across multiple blockchains. It provides a foundational communication layer for the multichain ecosystem, supporting decentralized validators for cost efficiency and security. Sub-protocols facilitate bridging, cross-chain logic proofs, multi-chain NFT/credential minting, and token-agnostic payments, easing developer experience in building interoperable applications. The protocol unlocks privacy-preserving social apps where users maintain control over historical actions, networks, and identities without exposing personal data. It integrates technologies like IPFS, soul-bound tokens (SBTs), and self-sovereign identity (SSI) solutions, including partnerships such as Polygon ID for multi-chain ZK proofs of verified credentials. Rarimo emphasizes ZK machine learning innovations and proof-of-personhood use cases to enhance Web3 privacy, security, and compliance.
