Polygon, a layer-2 scaling protocol for Ethereum, has launched a zero-knowledge decentralized identity solutionto 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.

“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
