META: Decentralize directory authorities as far as safely possible
We currently rely on a handful of directory authorities and their operators to generate and maintain the consensus of the Tor network. They're also the default place to go for clients to bootstrap into the network. Some research has been started into replacing the individual directory authorities with anonymity-preserving distributed hash table (DHT) models. Further this work, using simulators and/or private tor networks for handling future growth and expansion of the public tor network.
