Polygon released 4 massive tools to revolutionize the ID market

• The Polygon ID infrastructure introduces four tools including wallet SDK, wallet app, verifier SDK, and issue node.
• The Polygon ID framework comprises three modules: Identity Holders, Issuers, and Verifiers.

The team behind the Polygon blockchain has been working rigorously to bolster identification using the power of blockchain technology. The Polgon ID team is working towards building an infrastructure for a more equitable internet without compromising on the IDENTITY of individuals.

In the latest development, the Polygon ID team has released four tools with a move towards a self-sovereign future. These four tools include wallet SDK, wallet app, verifier SDK, and issue node.

The identity infrastructure of Polygon ID seeks to facilitate trusted and secure relationships between users and apps. By default, it follows the principles of self-sovereign identity and privacy.

Using Polygon ID, businesses and organizations can issue verifiable credentials about their users. Also, Polygon IDs offer zero-knowledge proofs that would allow users to provide their identity without exposing their personal information. Thus, it ensures freedom of expression without compromising privacy.

Every identity will be identified using a unique identifier dubbed decentralized identifier (DID). Also, the representations of identity-based information happen through verifiable credentials (VCs). Basically, a VC represents any kind of information related to an individual/enterprise/object. The VC could be a membership certificate issued by DAO or anything similar.

Architecture Framework of Polygon ID

The architecture of Polygon ID’s framework comprises three modules:

1. Identity Holder: This is an entity that holds claims in its wallet. The verifiable credentials (VCs) shall be issued by an issuer to the holders. The Identity Holder will generate a zero-knowledge proof of the VCs issued and shall present these proofs to the verifier.
2. Issuer: As said, an issuer is an entity that will issue VCs to the holders. This identity could be anyone such as a person, an organization, or a thing. Every verifiable credential (VC) comes from an issuer and is cryptographically signed by them.
3. Verifier: The job of the verifier is to verify the proofs presented by a holder. It will request the Holders to send proof based on the VCs they hold in their wallets. The Verifier performs a set of checks while verifying the proof.

Apart from these three, a wallet plays a crucial role in the seamless exchange of VCs with the issuer along with simultaneously exchanging the Proofs with the Verifier. Polygon explains:

At its core, the wallet stores the private key of a user, fetch VCs from the Issuer, and create zero-knowledge proofs to be presented to the Verifier. Being the carrier of the sensitive information, Wallet has been designed to ensure that the identity of its Holder is protected and preserved, and no sensitive data can be revealed to the third party without the consent of the Holder.

Some of the core benefits of using Polygon IDs are greater privacy with zero-knowledge proofs, self-sovereignty, on-chain and off-chain verification, transitive trust, etc.
