Introduction

Compatibility protocol Raremo entered into a partnership with Polygon ID, to enable use of Credential infrastructure that can be verified across multiple blockchains.

Rarimo and Polygon ID Collaboration

Rarimo, a tool that helps different blockchains talk to each other, has joined forces with Polygon ID, a system for verifying identities, to provide identity verification tools available across many different blockchains, turning Polygon ID into a multi-chain tool.

Expanded Identity Verification

Previously, Polygon ID only allowed identity verification on the blockchain where they were first set up. For example, if you made your identity on Polygon, you couldn’t use it on Ethereum (ETH), which means that users had to create a new identification card for every blockchain. However, with this partnership, IDs made on Polygon can now be used on Ethereum (MATIC). Other blockchains like BNB Chain (BNB) and Avalanche (AVAX) are also expected to join this list soon.

Polygon ID and Self-Identification (SSI)

Polygon ID uses Self-Identification (SSI), which allows institutions like banks or governments to issue important documents like university degrees or driver’s licenses. Users can keep these documents in a private digital repository and choose when and where they want to show them. The method called zero-knowledge proof allows users to prove who they say they are without revealing private information.

Polygon ID and Zero Cognitive Proofs

Polygon ID was first introduced in March 2022 and made available for free in the same year. It is the first and only system to use zero-knowledge proofs for offline documents. This allows users to submit their documents to smart contracts and participate with on-chain dapps, or decentralized applications. These zero proofs not only confirm that the document exists but also keep the user’s information secure.

The Future of Identity Verification

The partnership between Rarimo and Polygon ID shows a future where users can easily use documents from a range of sources, both on and off the blockchain, across many different systems and dapps. This also brings the concept of a future where users, rather than companies like Meta and Google, are in control of their identities, making the process of verifying identities more secure and private.
