How many irons do I need for a full beacon?

Could you please clarify for me, what do you mean by "irons" in the context of building a full beacon, and what type of beacon are you referring to? Is it a mining beacon, a communication beacon, or something else entirely? Depending on the specific beacon and its requirements, the number of "irons" needed may vary significantly. If you're asking about a cryptocurrency mining beacon, for example, it's not a common term, and the process usually involves specialized hardware, such as ASIC miners or GPUs, rather than traditional "irons." Could you provide more context or detail about your inquiry?
