The number of bakers has dropped in recent months. It could be related to yields on decentralized finance applications being more attractive than baking, regulatory mumblings in different jurisdictions, the only GUI solution (Kiln) being problematic or increasing hardware requirements.
A smaller number of bakers impacts the decentralization of the network negatively. To counter this trend, a clear approach is lowering barriers to becoming a baker:
Lowering the roll size.
Another factor in the roll size might be the price of XTZ. At the end of the Athens upgrade, when the roll size was reduced from 10,000 XTZ to 8,000 XTZ, the price of XTZ was ~ US$0.50. It sits over $5.00 at the time of writing.
Of course, the size of the roll should be high enough for bakers to take the responsibility seriously.
Should the roll size be reduced? What are the tradeoffs? What is the right roll size?
