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

The Polygon ID service makes use of zero-knowledge proofs (ZK proofs) that use cryptographic techniques 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 released Polygon ID on March 1, nearly 12 months after the undertaking was officially launched in a closed-source environment.

The Polygon workforce says Polygon ID was constructed to “resolve the problem 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 mentioned.

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

Customers will be capable to produce zero-knowledge proofs utilizing off-chain credentials — similar to their passport, nationwide ID or a bachelor’s diploma — to work together with good contracts and confirm data on-chain.

“Which means 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 device that enables customers to carry credentials domestically on handheld gadgets similar to smartphones, and that customers will 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 isn’t taken up by password resets.”

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

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

A number of initiatives have already dedicated to integrating Polygon ID upon launch, similar to Web3 infrastructure supplier Kaleido, ID verification answer Fractal and Web3 group administration system Collab.Land. Collectively they’ve a consumer base of over 4 million, based on Polygon.

Different Web3 initiatives, similar to metaverse platform The Sandbox and blockchain builder group, are within the strategy 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 this time embrace Quadrata and IDNTTY.
