One way to make money would be running a server.

Another to share files that are in demand but in risk of being
incomplete. People will pay a lot for the last block of a file so you
could charge a lot for rare chunks. I'm aware that that can cause a
stock exchnage effect making the price of files open to
speculation.

  "Should I download that block now and resell it to others?  Lets do
  that, it seems to become popular." "Hey, someone needs that block,
  its getting popular, lets rise the pirce."

But note that if you have files that not many people want and you want
to download something popular you might have a problem getting the
first block. But as soon as you got that you can share that block to
multiple people to get several times your money back.


I know the system is not perfect and leaves some desires. I'm still
thinking about it.

One big problem is that servers drain out money, so people running
servers get insanely rich unless they download as well (overnet uses
the clients as distributed server so no problem there). Because of the
drain money has to be constantly created or servers have to give money
presents to people or some.

Another is copying of money or plain faking it. This could lead to a
level of mistrust that you can hardly get anything shared because
noone has compatible (trusted) money. I want the system to be hardened
against evil clients without the need of a central authority and thats
the hardest part.

Another problem is that you can only download as fast as you
upload. Both sides have to balance out. So to get more download speed
you have to upload something valuable and download something cheap.
