At Polygon, we believe that putting people firmly in control of their digital identities is at the core of Web3’s promise to empower users over networks. We have been working behind the scenes to fulfill this promise and today are proud to introduce Polygon ID, the self-sovereign, decentralized and private identity for the next iteration of the Internet.
What makes this new identity platform unique is that it is first ever to be powered by zero-knowledge (ZK) cryptography, a privacy and blockchain scaling technology. Polygon has made ZK a centerpiece of its strategic vision and has committed $1 billion to related projects. Polygon ID is the latest product in this rapidly growing portfolio.
Polygon ID has the following properties:
Polygon ID leverages the Iden3 protocol and Circom ZK toolkit. Moving forward, both of the projects will be sponsored by Polygon while keeping the original spirit of community initiatives to provide open source protocols and tools to the broader ecosystem of developers.
“Polygon ID is private by default, offers on-chain verification and permissionless attestation. There is nothing in the digital identity space now that ticks all these boxes,” said Mihailo Bjelic, Polygon’s co-founder. “It is also a great showcase for how zero knowledge proofs can help us create a better world.”
Privacy is a fundamental human right and Polygon ID empowers the users to reclaim it. Because it is private by default, access control is based on proving verifiable information rather than sharing it with the verifier.
Polygon ID allows for the construction of new forms of reputations. Some examples include decentralized credit score for financial primitives and social payments in DeFi; decentralized sybil score, voting power / delegation and domain-expertise reputation for DAOs to enable new decision-making and governance models; player reputation profile for Web3 games; private and censorship-resistant P2P communication and interactions for social applications.
Polygon ID is a complete platform that can be used to construct a variety of identity and trust services. The team is creating an open and enterprise-ready ecosystem for trust markets and trust management to build new attestation and access services with an incentive layer.
Polygon ID is currently under development. The solution will be structured as a set of tools, platform services and examples for developers to learn, test and integrate with their apps or dApps leveraging Polygon ID’s unique on-chain capabilities.
The product portfolio (focus on simplicity and inclusiveness) is the following:
