The Rarimo interoperability protocol has partnered with Polygon ID, enabling the use of its verifiable credential infrastructure across multiple blockchains.
Rarimo, a tool that helps different blockchains communicate with each other, has joined forces with Polygon ID, a system for verifying identities, to make its identity verification tools available on many different blockchains, making Polygon ID a multi-chain tool.
Polygon ID had previously allowed identity checks only on the blockchain where they were first set up. For example, if you created your ID on Polygon, you couldn’t use it on Ethereum (ETH), meaning users had to create a new ID for each blockchain. But now, with this association, IDs made in Polygon (MATIC) can be used on Ethereum. Other blockchains such as BNB Chain (BNB) and Avalanche (AVAX) are also expected to join this list soon.
Polygon ID uses Self-Sovereign Identity (SSI), which allows institutions like banks or governments to issue important documents like college degrees or driver’s licenses. Users can save these documents in private digital wallets and choose when and where to display them. A method called zero-knowledge proof is used that allows users to prove that they are who they say they are without revealing any private information.
Polygon ID, first introduced in March 2022 and freely available in March of the same year, is the first and only system to use these zero-knowledge proofs for off-chain documents. This allows users to send their documents to smart contracts and interact with on-chain dapps or decentralized applications. These zero-knowledge proofs not only confirm the existence of the document, but also keep the user’s information safe.
The partnership between Rarimo and Polygon ID shows a future where users can easily use documents from a variety of sources, both on and off the blockchain, across many different systems and dapps. This also brings a concept of a future where users, and not corporations like Meta and Google, are in control of their identities, making the identity verification process more secure and private.
