Polygon ID developers have released four new tools for their decentralized identity infrastructure.
In a tweet on Mar. 5, Polygon said these tools would allow for building a more equitable internet with identity at the center.
Polygon ID uses zero-knowledge (ZK) proofs, allowing users to verify their identity trustlessly without revealing their personal information.
This system is anchored on anon3, a protocol through which users can trustlessly prove their access rights without divulging their information.
Under the hood, the Polygon ID framework comprises the Identity Holder, Issuer, and Verifier, forming what they describe as a “triangle of trust”.
Because of ZK, Polygon ID ensures the user has freedom of expression and privacy by default. This diverges from centralized legacy systems where critical personal information must be submitted to a third party.
Tools include the Verifier software development kit (SDK), issuer node, and wallet SDK. There is also the Wallet App. All these toolsets, Polygon explained, are compatible with the W3C standards.
The verifier is tasked with verifying the proof presented by the holder, who controls a wallet. In this arrangement, because the holder can access the wallet, they are responsible for creating ZK proofs of the verifiable credentials (VCs) issued.
Meanwhile, the issuer is an entity that gives out VCs to the holder.
Under Polygon ID’s “triangle of trust”, the wallet is designed to protect the holder’s privacy and identity.
Data privacy and control
Polygon is building an Identity Infrastructure that facilitates a secure, trusted relationship between integrating dApps and end users.
Platforms incorporating Polygon ID will have their user data protected by default. At the same time, users would have self-sovereign of their data.
According to Polygon, corporations that choose to use their solution will, at any instant, issue verifiable credentials about their users.
Meanwhile, organizations would also be empowered. They can, on-demand, verify claims via a suite of tools created for each member of its ecosystem.
Polygon is an Ethereum layer-2 solution with higher scalability and low trading fees. Because of its compatibility with the Ethereum virtual machine (EVM), many projects wishing to connect with the first smart contracting platform opt to deploy on Polygon. Over the years, Polygon has developed an active DeFi, NFTs, and gaming ecosystem.
