What does Karma do?
• Karma is a peer to peer filesharing software which works much like LimeWire, Ares etc.
• But, the way it works under the hood is a little bit different – we’ll explain that in the next slide.
user guide
Karma is delay-tolerant
• On regular P2P software, if a file is not available on the network at the time you search for it, it is not shown in the search results.
• In Karma, we make sure you get the files you want, whether they’re offline or online when you search.
user guide
How does it work?
• Karma is social – your friends help you get the files you want!
• If you’re not online when a file you requested becomes available, Karma distributes that file to your friends!
user guide
How does it work?
• Because you and your friends are generally online together, you’re more likely to get the file you want the next time you’re online –because all your friends have it!
• This makes the Karma network delay tolerant!

What does this mean for you?
• Karma is based on the principle of ‘what goes around, comes around’.
• Because your bandwidth is being used to replicate files for your friends, your friends do the same for you!
• The more you share, the more you get.
