Blind signature

A blind signature is a form of digital signature that allows one party to sign a document without being able to see its contents. This cryptographic technique is often used to maintain privacy and anonymity in various applications, such as voting systems, electronic cash, and anonymous credentials. ### How Blind Signatures Work: 1. **Blinding Process**: The signer (typically a person or entity who has the authority to sign) receives a message (or document) from the requester (who wants the signature).
