What is a mintner?

Could you please elaborate on the term "mintner" in the context of cryptocurrency and finance? I'm not entirely familiar with this terminology and would appreciate a clear and concise explanation. Are they akin to miners in the blockchain space, or do they have a unique role and function? Additionally, if possible, could you provide some insight into the processes and mechanisms involved in their work, as well as any potential benefits or drawbacks of being a mintner?
