How to run a Bittensor validator?
Could you please elaborate on the process of operating a Bittensor validator? I'm interested in understanding the steps involved in setting up and maintaining a validator node. Could you provide a brief overview of the hardware and software requirements? Additionally, could you explain the role of validators in the Bittensor network and how they contribute to its security and decentralization? It would also be helpful if you could discuss any challenges or considerations that one might encounter while running a validator. Thank you for your assistance in clarifying this topic.
