Ring Signature

A “ring signature” is a mechanism for concealing the specifics of a digital signature in order to conceal the specifics of the relevant network transaction. This one-of-a-kind digital signature format can be used by any member of a group of users who has the necessary cryptographic keys. As a result, determining which group member’s keys were used to generate the signature is nearly impossible, allowing the sender of a transaction to remain anonymous and untraceable. The ring-like structure of the signature algorithm inspired the name “ring signature,” and Monero was the first blockchain network protocol to implement ring signatures in 2015.
