Rarimo, an interoperability protocol that facilitates communication between different blockchains, has teamed up with Polygon ID, a system for verifying identities. This partnership allows the verifiable credential infrastructure of Polygon ID to be utilized across multiple blockchains.
Before this collaboration, Polygon ID only allowed identity verification within the blockchain where the identities were originally created. For instance, if you had your ID on Polygon, you couldn’t use it on Ethereum (ETH), necessitating the creation of a new ID for each blockchain. However, with this new partnership, IDs generated on Polygon (MATIC) can now be used on Ethereum, and other blockchains such as BNB Chain (BNB) and Avalanche (AVAX) are expected to join the list soon.
Polygon ID employs Self-Sovereign Identity (SSI), enabling institutions like banks or governments to issue important documents, such as university degrees or driving licenses, which users can store securely in private digital wallets and selectively disclose as needed. This system uses a method called zero-knowledge proof, which allows users to verify their identity without revealing sensitive information.
Introduced in March 2022 and made freely available the same year, Polygon ID is the first and only system using zero-knowledge proofs for off-chain documents. This capability empowers users to submit their documents to smart contracts and engage with on-chain decentralized applications (dapps), all while ensuring the confidentiality of their personal information.
The collaboration between Rarimo and Polygon ID envisions a future where users can effortlessly use documents from various sources, both on and off the blockchain, across diverse systems and dapps. This partnership also promotes the idea of a future where individuals, rather than corporations like Meta and Google, have control over their identities, resulting in a safer and more private identity verification process.
