What is the max supply of CKB?

I'm curious about a specific aspect of CKB, its maximum supply. Could you please explain what the maximum supply of CKB is? I'm trying to understand the potential scarcity or abundance of this cryptocurrency and how it might affect its value in the market. Would the maximum supply be a fixed quantity, or does it have the potential to change over time? It would be helpful if you could provide some insight into this matter.
