Ring Signature

A ring signature is a cryptographic technique used to provide anonymity in digital transactions or communications. It allows a message or transaction to be signed by a group of individuals in such a way that it is computationally difficult to determine which specific individual signed it. Ring signatures ensure privacy by creating a ring of possible signers, where any member of the ring can produce a valid signature without revealing their identity. This technique is commonly used in privacy-focused cryptocurrencies to obscure the origin of transactions and maintain the pseudonymous nature of participants.
