Polygon has launched a zero-knowledge decentralized identity solution to the public nearly a year after announcing its development.
The Polygon ID service uses zero-knowledge proofs (ZK proofs) that use cryptographic techniques to allow users to verify their identity online without having their sensitive information passed or potentially stored with a third party.
Polygon Labs publicly released Polygon ID on March 1, almost 12 months after the project was officially launched in a closed-source environment.
The Polygon team says Polygon ID was built to “solve the issue of digital trust.”
“What sets Polygon ID apart from most other decentralized ID frameworks is its implementation of zero-knowledge technology, allowing users to verify their identities or other credentials without necessarily revealing sensitive information,” Polygon said.
The public release introduces four new tools to the Polygon ID toolset such as Verifier SDK, Issuer Node, Wallet SDK and Wallet App that will allow developers building on Polygon to integrate identity solutions into their applications.
Users will be able to produce zero-knowledge proofs using off-chain credentials such as their passport, national ID or a bachelor’s degree to interact with smart contracts and verify information on-chain.
Polygon claims it’s also the first ZK-based digital ID tool that allows users to hold credentials locally on handheld devices such as smartphones, and that users will no longer need passwords.
