There are no specific whitelisting requirements for running a node. The system is designed to be trustless, meaning you can join and run a node without special permissions. You'll need to set up a valid Sui wallet, which can be done via the Sui CLI. Ensure that you have some SUI tokens, as they are necessary for transactions. You can set up a testnet wallet using the full node endpoint https://fullnode.testnet.sui.io:443 for testing purposes.The process involves running the Walrus binary client, which is available for multiple platforms including macOS, Ubuntu, and Windows. Once installed, configure your client by creating a client configuration file that includes the necessary system, staking, and subsidies objects.

To run a Walrus node, you can refer to the detailed operator guide available at this link: https://docs.walrus.site/operator-guide/operator-guide.html. Here you can find all necessary details for both installation and operation of a node.
