Polygon ID, a decentralized identity solution for public use, has released four tools to enhance its identity infrastructure aimed at creating a more equitable internet with identity at its core.
The infrastructure fosters trusted and secure relationships between users and apps while adhering to the principles of self-sovereign identity and privacy by default.
The tools are the Verifier SDK, Issuer Node, Wallet SDK, and Wallet App. Polygon ID allows users to prove their identity without exposing their private information by utilizing zero-knowledge proofs, ensuring both the freedom of expression and privacy by default.
On March 1st, Polygon, a layer-2 scaling protocol built on Ethereum, launched Polygon ID, a decentralized identity solution using zero-knowledge technology, which is now available for public use, according to a previous report by TronWeekly.
The Architecture Of Polygon ID: The Triangle Of Trust
According to the blog post, Polygon ID identifies every identity using a unique decentralized identifier called DID, with identity-based information represented via Verifiable Credentials (VCs).
A VC can represent any information related to an individual, enterprise, or object, such as a membership certificate issued by a DAO or the highest degree held by an individual. The framework’s architecture is composed of three modules: the Identity Holder, Issuer, and Verifier forming what Polygon ID calls the triangle of trust.
The Identity Holder is an entity that holds claims in its wallet and generates zero-knowledge proofs of the VCs issued, which are presented to the Verifier for authentication. The Issuer is the entity issuing VCs to the Holder, and every VC is cryptographically signed by the Issuer.
The Verifier verifies the proof presented by the Holder and performs a set of checks to ensure the VC was signed by the expected Issuer and that it matches the criteria requested by the Verifier.
Additionally, the wallet plays a crucial role in the seamless exchange of VCs with the Issuer and proofs with the Verifier, with the user’s private key stored in the wallet. The wallet ensures that the identity of the Holder is protected and preserved, and sensitive data cannot be revealed to third parties without the Holder’s consent.
