Interoperability Protocol Rarimo has partnered with Polygon ID, enabling its verifiable credentials infrastructure to be used across multiple blockchains.
Rarimo, a tool that helps different blockchains talk to each other, has partnered with Polygon ID, an identity verification system, to make their identity verification tools available on many different blockchains, turning Polygon ID into a multi-chain tool.
Polygon ID previously only allowed identity checks on the blockchain where they were first implemented. For example, if you created your ID on Polygon, you cannot use it on Ethereum (ETH), which means users must create a new ID for each blockchain. But now, with this partnership, credentials created on Polygon (MATIC) can be used on Ethereum. Other blockchains like BNB Chain (BNB) and Avalanche (AVAX) are also expected to join this list soon.
Polygon ID uses Self-Sovereign Identity (SSI), which allows institutions such as banks or governments to issue important documents such as college degrees or driver’s licenses. Users can keep these documents in private digital wallets and choose when and where to show them. A method called zero-knowledge proof is used which allows users to prove they are who they say they are without revealing any private information.
Polygon ID, first introduced in March 2022 and made available for free in March of the same year, is the first and only system to use such zero-knowledge proofs for off-chain documents. This allows users to submit their documents to smart contracts and engage with on-chain dapps or decentralized applications. These zero-knowledge proofs not only confirm the existence of the document, but also protect the user’s information.
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. It also brings a concept of the future where users, and not companies like Meta and Google, are in control of their identity, making the identity verification process safer and more private.
