How to be a full node?

Thanks for the precisions io_jeremy.

You guess this picture is from the design team as a design template, so I guess this means that on dec 3rd the real percentages were really different from the numbers on the picture ?

Where is it possible to see the reality (today) ?

Is there a precise link somewhere (showing such a picture as above, but with actual numbers) ?

I may be an interested node maintainer, but before deciding something, and since Cardano ADA claims to be based on PoS, it’s necessary to have a good idea about how many ADAs are needed to have a viable stake percentage.

Thanks.
