In order for Tor to successfully anonymize its users, it has to bounce their traffic between a number of relays to obfuscate their identity, but it can’t keep bouncing forever and will eventually need to exit through an exit node. The problem is that, be it because of the constant questions from law enforcement or DMCA takedowns from entertainment groups, the people running these essential exit nodes many times end up taking them down. The Tor Project has found an ingenious solution to this problem, however, one which would also dramatically increase the speed of the Tor network by turning legally-protected public libraries into exit node hubs.
