I was just wondering. Looking at mytezosbaker webpage, there are so many great bakers which provide delegation services, right.
1) So I was interested in knowing: How do those services achieve that? How can one be a baker? What are technical (hardware/software) & financial &other requirements?
2) And is the financial ROI reward identical in percentage for bakers and for those who delegate their XTZ to bakers? Or do bakers receive higher annual rewards (what is the formula for bakers?)?
3) And finally, must a baker be always online, what if not? What impact has the online-uptime on your baking rewards ?
Is there a clear-written guide available about baking somewhere ?
