No, you cannot run a node without staking tokens on the Aptos network. To run a node, you need to meet some requirements, such as having sufficient compute and storage resources, staking a minimum amount of tokens, and registering your nodes on the Aptos community platform. The minimum amount that a validator must stake is 1M APT tokens, which is equivalent to about $10,000 USD at the current market price. Staking tokens is necessary to ensure that the node operators have a stake in the security and performance of the network, and to reward them for their contributions.
Staking tokens also allows you to participate in the Aptos governance, where you can vote on proposals that affect the network parameters, such as fees, rewards, lockup periods, etc. You can also delegate your voting power to another account if you do not want to vote yourself. By staking tokens, you can have a say in the future direction of the Aptos network and benefit from its growth and innovation.
If you are interested in running a node on the Aptos network, you can visit the Aptos documentation website, where you can find detailed guides, tutorials, and references for setting up and operating your nodes. You can also join the Aptos community on Discord or Telegram, where you can interact with other node operators, developers, and users of the Aptos network.
