In its Wednesday blog post, Polygon, the popular Ethereum Layer-2 scaling solution, announced the upcoming release of Polygon ID, its brand-new Web3 identity infrastructure based on zero-knowledge cryptography. Polygon first shared news about the development of the new tool in March 2022, which company described as "a blockchain-based ID for decentralized and self-sovereign models"
At the time, Polygon ID was intended to support "scalable and private on-chain verification to boost decentralized apps and decentralized finance" and to be "open to existing standards and ecosystem development."
It seems that Polygon's developers have succeeded in bringing the project to life. According to Polygon, many Web3 projects have already started leveraging zero-knowledge proofs, a complex cryptographic method that makes it possible to prove the validity of information only by stating that it is indeed true, without the need to convey additional data.
Companies using Polygon ID range from community management tools that use token ownership for membership curation, like Collab.Lab, to P2P payment applications such as DePay. The decentralized point-to-point airline Moov Airways AG, the digital passport application Clique, the NFT aggregator and wallet Komet, and the popular Web3 game The Sandbox prove that Polygon's zero-knowledge ID service can be used in a broad set of use cases.
