 Polygon zkEVM's Mainnet Beta is available for developers to launch smart contracts, execute transactions, and experiment with the network. This tutorial extends the exploration by allowing developers to launch their own production zkNode.

 After spinning up an instance of the production zkNode, you will be able to run the Synchronizer and utilize the JSON-RPC interface.

 The Ethereum node is the first component to be set up. And it is because the Ethereum network takes a long time to synchronise. So, we start synchronising the Ethereum Node, and then begin to setup other components while waiting for the synchronisation to complete.
