In essence, bar owners can verify customer age with Polygon ID without having to see any identification.
On the evening of March 1, Polygon revealed that it was about to launch a new product Polygon ID based on Zero Knowledge Proof (ZK) technology, which helps verify users’ identities while keeping their personal information private.

According to the company, the new Polygon ID toolkit is useful for developers in unlocking the user interface, assisting with regulatory compliance, identity verification, access control, or some tokenized feature. other.
Polygon ID can be applied in KYC processes on centralized exchanges, DeFi platforms, as well as on-ramps and off-ramps fiat payments.
Zero-Knowledge is one of this year’s hottest trends because it eliminates the need to regularly provide personal information to websites or online apps. This technology has long been seen as an advancement and potential use case for blockchains.
For ease of understanding, let’s look at an example. To enter a bar, users usually have to provide identification to prove their age. However, if using Polygon ID, users only need to provide one proof.
This proof can be done off-chain or on-chain through smart contracts. The Polygon Labs team will integrate this identification toolkit into Polygon zkEVM, which is expected to coming out later this month and is expected by the community.
zkEVM is a layer-2 solution for Ethereum that evolves towards zk-Rollups and uses Zero Knowledge Proof security to verify data and improve privacy.
