What is zk polyhedra?

Could you please elaborate on the concept of zk polyhedra? I'm intrigued by the term but not entirely familiar with its implications in the realm of cryptocurrency and finance. Is it a new cryptographic primitive that offers enhanced privacy or security features? Or does it relate to a specific protocol or framework within the blockchain ecosystem? I'd appreciate it if you could provide a concise yet comprehensive explanation of zk polyhedra and its potential applications in our field.
