Polygon, a layer-2 scaling protocol for Ethereum, has launched its decentralized identity solution, Polygon ID, to the public. The system uses zero-knowledge proofs (ZK proofs) to enable users to verify their identity online without sharing sensitive information with third parties.
Polygon ID has been in development for almost a year and was launched to a select group of builders in a closed-environment. This development is set to revolutionize the way digital identities are stored and used in the Web3 space.

Polygon has stated that its Polygon ID framework sets itself apart from other decentralized ID frameworks by implementing zero-knowledge technology. This allows users to verify their identities or other credentials without revealing sensitive information.
The public release includes four new tools for the Polygon ID toolset – Verifier SDK, Issuer Node, Wallet SDK, and Wallet App, which will allow developers to integrate decentralized identity into their applications.

The system uses off-chain credentials, such as passports and national IDs, to enable users to produce zero-knowledge proofs that can interact with smart contracts and verify information on-chain.
“With Polygon ID, off-chain data in the Verified Credential format can now be used for on-chain verifications, ensuring trustless transactions.”
Polygon claims that it is the first ZK-based digital ID tool that allows users to hold credentials locally on handheld devices such as smartphones. This feature eliminates the need for passwords.
Passwordless logins will be enabled through encrypted verifiable credentials that can be exchanged by scanning a QR code or connecting to a desktop wallet. This will offer organizations better security, an improved user experience, and greater productivity for system administrators who will no longer have to spend time resetting passwords.
David Schwartz, co-founder of Polygon ID, said that the product was built on the latest decentralized identity standards and would help protect developers and users against unauthorized access from third parties.
Polygon ID’s ZK-based technology enables developers to build solutions to allow users to store their personal information privately and securely while giving them full control over who has access to their data.

Multiple projects, including Kaleido, Fractal, and Collab.Land, have already committed to integrating Polygon ID upon launch, with a combined user base of over 4 million.
With other Web3 projects such as The Sandbox and Guild.xyz in the process of integrating Polygon ID, it’s clear that this new tool will have a great impact on the blockchain identity management space.
Following the news, the price of Polygon’s native token, MATIC, increased 2.5% from $1.22 to $1.25 in a matter of hours. Other blockchain-based ID products in the space include Quadrata and IDNTTY.
The launch of Polygon ID highlights the growing interest in decentralized identity solutions, which aim to solve the issue of digital trust.
