I wonder for which reason the nodes secure the network. As far as I am concerned they are the only members of the network who guard it and by that secure it. But they aren’t rewarded. They also have to spent power and furthermore have the hardware costs.
Is it just the ideology or believe in the projects drives them? Or is there any sort of reward to ensure that the network will permanently have enough guards? Or do they just want to be aware that the network which they use works as intended. Furthermore, have all information’s saved?
