Inquiring minds want to know: Could you please elaborate on the steps involved in setting up and operating an Iagon node? I understand that Iagon utilizes blockchain technology and distributed computing to offer a decentralized cloud computing platform, but the specifics of node operation remain a mystery to me. Are there any prerequisites in terms of hardware or software? Do I need to stake any coins? What kind of maintenance is required to ensure the node's continuous operation? Your insights into this process would be greatly appreciated.
