Polygon launches decentralized ID product powered by ZK proofs

Polygon, a layer-2 scaling protocol for Ethereum, has launched a zero-knowledge decentralized identification solutionto the general public almost a yr after saying its growth.

The Polygon ID service makes use of zero-knowledge proofs (ZK proofs) that use cryptographic methods to permit customers to confirm their identification on-line with out having their delicate data handed or probably saved with a 3rd occasion.

Polygon Labs publicly launched Polygon ID on March 1, virtually 12 months after the challenge was formally launched in a closed-source atmosphere.

The Polygon crew says Polygon ID was constructed to “clear up the difficulty of digital belief.”

“What units Polygon ID aside from most different decentralized ID frameworks is its implementation of zero-knowledge expertise, permitting customers to confirm their identities or different credentials with out essentially revealing delicate data,” Polygon stated.

The general public launch introduces 4 new instruments to the Polygon ID toolset — Verifier SDK, Issuer Node, Pockets SDK and Pockets App — that may permit Polygon builders to combine decentralized identification into their functions.

Customers will have the ability to produce zero-knowledge proofs utilizing off-chain credentials — corresponding to their passport, nationwide ID or a bachelor’s diploma — to work together with sensible contracts and confirm data on-chain.

“Which means that off-chain information can now be used for trustless on-chain verifications within the widely-supported Verified Credential format.”

Polygon claims it’s additionally the primary ZK-based digital ID instrument that permits customers to carry credentials regionally on handheld gadgets corresponding to smartphones, and that customers will now not want passwords:

“Passwordless logins change encrypted verifiable credentials by merely scanning a QR code or connecting to a desktop pockets. Organizations can profit from improved safety, a greater consumer expertise, and productiveness of their system directors whose time will not be taken up by password resets.”

The co-founder of Polygon ID, David Schwartz, stated in a March 1 tweet that the product was constructed “on the most recent decentralized identification requirements” which is able to assist shield builders and customers towards unauthorized entry from third events.

“Offering identification in a means that the common shopper can use is the holy grail of digital ID adoption,” he defined in a separate press assertion.

A number of tasks have already dedicated to integrating Polygon ID upon launch, corresponding to Web3 infrastructure supplier Kaleido, ID verification answer Fractal and Web3 neighborhood administration system Collab.Land. Collectively they’ve a consumer base of over 4 million, in accordance with Polygon.

Different Web3 tasks, corresponding to metaverse platform The Sandbox and blockchain builder neighborhood Guild.xyz, are within the technique of integrating Polygon ID too.

Following the information, the value of Polygon’s native token, MATIC (MATIC), elevated 2.5% from $1.22 to $1.25 in a matter of hours earlier than falling again to $1.23.

Different blockchain-based ID merchandise out within the area at the moment embody Quadrata and IDNTTY.
