+export const whitelistNotRequired =`👋 Hey! In preparation for Testnet {4}, we've launched a Genesis Node Operators Application form to collect node specification details from Node Operators.
+
+The Testnet Phase {4} introduces the Fleek Network Genesis Operators (GO’s), comprising approximately 50-100 initial node operators selected by the Foundation based on both merit and geographic location to operate nodes during the Phase {4} testnet–the Fleek team will reach out to the selected node operators. Stay informed by checking the blog for updates on the selection process. If you haven't been contacted, it indicates that you were not selected.

+For any further conditions and rules to operate a node, you'll have to check our <https://blog.fleek.network> and documentation <https://docs.fleek.network> to learn more, please 🙏`;
