What is the gas token on the zkSync era?
Could you please elaborate on the concept of the gas token within the zksync era? As a cryptocurrency enthusiast, I'm intrigued by how this particular token functions within the zkSync ecosystem and what role it plays in facilitating transactions. Is it a necessary component for users to interact with the network, or is it more of an optional feature? Additionally, how does the gas token differ from those used in other blockchain networks, and what are the benefits of utilizing it within the zkSync framework?
