N2 - Tor, a distributed Internet anonymizing system, relies on volunteers who run dedicated relays. Other than altruism, these volunteers have no incentive to run relays, causing a large disparity between the number of users and available re- lays. We introduce BRAIDS, a set of practical mechanisms that encourages users to run Tor relays, allowing them to earn credits redeemable for improved performance of both interactive and non-interactive Tor trafic. These perfor-mance incentives will allow Tor to support increasing re-source demands with almost no loss in anonymity: BRAIDS is robust to well-known attacks. Using a simulation of 20,300 Tor nodes, we show that BRAIDS allows relays to achieve 75% lower latency than non-relays for interactive trafic, and 90% higher bandwidth utilization for non-interactive trafic.
