Zero-Knowledge Proofs (ZKPs) enable identity verification without revealing personal details, a key feature in KYC processes. WorldCoin uses iris scanning to generate a unique World ID, leveraging ZKPs to ensure privacy. However, collecting biometric data raises concerns about potential misuse and accessibility, despite encryption efforts. In contrast, Polygon ID offers a decentralized, self-sovereign identity solution, using ZKPs to verify credentials without exposing sensitive information. Privacy Trade-off: WorldCoin’s biometric approach risks greater privacy breaches due to the sensitivity of iris data, while Polygon ID minimizes data exposure, offering stronger privacy protection. Thus, Polygon ID may be the more privacy-friendly option.
