What is the max supply of ZEC?

As a cryptocurrency enthusiast, I'm curious to understand the economic principles behind various digital assets. Could you elaborate on the maximum supply of ZEC? Is it finite, like Bitcoin, or does it have a variable supply? Understanding the supply dynamics is crucial for investors to make informed decisions about potential value appreciation or depreciation in the future. Furthermore, what impact does this maximum supply have on the network's decentralization, scalability, and security? Thank you for clarifying this key aspect of ZEC's economic model.
