Proxies are votes cast on behalf of a participant in a democratic or parliamentary system by the participant's delegate or representative.
I want to punch you, but don't want to get in trouble, so I ask someone to punch you and not tell you I told them to punch you, and if they tell you who told them to punch you, they're transparent; if they don't tell you who told them to punch you but they do tell you someone did tell them to punch you, they're anonymous; if they don't tell you anyone told them to punch you, they're high anoynmous/elite.
Something allowed to act on behalf of another.
