"I don't think I could run a node."
At least on Bitcoin it amounts to basically keeping a computer program running that uses bandwidth constantly. No special hardware is required, beyond a PC connected to the internet. It can be helpful to store the whole blockchain, which will require some disk space, but you don't really need to.
I believe in you.
Run a node for me, when I am gone.
Spring is in the air, and I need to put one in my step.
