Hidden Services (HS) are mechanisms designed to provide network services while preserving anonymity for the identity of the server. Besides protecting the identity of the server, hidden services help to resist censorship, are resistant against distributed DoS attacks, and allow server functionality even if the service provider does not own a public IP address. Currently, only the Tor network offers this feature in full functionality. However, the HS concept in Tor is complex and provides poor performance. According to recent studies, average contact time for a hidden service is 24s which is far beyond what an average user is willing to wait.
