Tor是一个分布式的互联网匿名系统，它依赖于运行专用中继的志愿者。除了利他主义，这些志愿者没有动力跑接力，导致用户数量和可用接力之间的巨大差距。我们介绍BRAIDS，这是一套实用的机制，鼓励用户运行Tor中继，允许他们赚取积分，以改善交互式和非交互式Tor流量的性能。这些性能激励将允许Tor在几乎没有匿名性损失的情况下支持不断增长的资源需求：BRAIDS对众所周知的攻击是健壮的。通过对20,300个Tor节点的模拟，我们表明BRAIDS允许中继在交互流量中实现比非中继低75%的延迟，并且在非交互流量中提高90%的带宽利用率。
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 relays. 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 traffic. These performance incentives will allow Tor to support increasing resource 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 traffic, and 90% higher bandwidth utilization for non-interactive traffic.
