Sometimes you need to know information about your client like "Are you over 19?"
We use zero-knowledge proofs to confirm information without revealing everything. Develop trust with your collaborators while maintaining confidentiality of proprietary information. A zero-knowledge proof allows one party (the prover) to demonstrate to another party (the verifier) that a certain statement is true, without revealing any additional information beyond the statement itself. This means that you can confirm important information with your collaborators without disclosing any confidential data.
How it works:
To use a zero-knowledge proof, the verifier poses a question, such as "Are you over 19?" The user uses a digital witness to produce a cryptographically provable digital proof of the answer, which is recorded by the verifier. To prevent reuse, the verifier asks additional questions, such as the current date or a code word.
Before any information is shared, the user must first provide explicit consent to release the information to the verifier. The verifier cannot reuse the digital proof to impersonate the user, as the zero knowledge-proof includes the time it was created and the unique passcode. The verifier would only receive the specific information that they requested. To ensure the privacy and security of the information exchange, encryption can be used so that only the verifier and user have access to the information.
