What main aspects make Polygon ID unique?

Polygon ID following features make it unique:

• Private by default solution, as a result of the ZK native protocol used.

• There is no direct communication between issuer and verifiers.

• Offering a scalable and self-sovereign digital identity solution.

• Allows on-chain and off-chain verification, facilitating the deployment of both web2 and web3 use cases.

• Supports bulk issuance of claims with a highly efficient on-chain storage at a minimum transactional cost.

• It enables a wide range of use cases to settle the foundation for a transformative impact with:

• protection against Sybil attacks while preserving privacy. This is achieved using nullifier techniques that assure that an identity (human being) can undertake an action only once. This becomes a key feature for specific use cases such as voting processes.

• non-reusable proofs: guaranteeing the verifier that the proof presented by the user was not a copy of a proof generated by another identity, and allowing the verifier to check its validity.

• Protection against digital footprint tracking.
