title = "Adding incentives to file-sharing systems",
abstract = "Modern peer-to-peer file sharing systems rely heavily on the willingness of users to distribute files to others. A selfish user can choose to download a file and consume resources without uploading in return. This form of free-riding plagues all currently deployed peer-to-peer systems. We present a novel protocol for a BitTorrent.-like system (i.e.. one in which only one file is being shared) that strongly discourages users from downloading a file without sharing it. Our protocol requires very little computation, and can easily be implemented in today's peer-to-peer systems. It is resistant to all forms of manipulation, including the use of multiple free identities, and does not require any coordina-tion among seeds. We analyze our protocol and show that if downloading peers are rational, a new system equilibrium is reached in which all peers upload at least some percentage of the file they are given.",
