zk-STARKs

Common use cases for zero-knowledge proofs are where both privacy and security are essential. An example is identity authentication. Using certain online services requires proving your identity and right to access those platforms. This often requires providing personal information such as name, email, birth date, and more.

Zero-knowledge proofs can simplify authentication for both platforms and users. Once a zk-proof has been generated using public inputs (data confirming the user's membership of the platform) and private inputs (the user's details), the user can simply present it to authenticate their identity whenever they need to access the service. This improves the experience for users and frees organizations from the duty to store huge amounts of personal information.
