The last Tor relay sends and receives back traffic like if it would have been the actual user's computer. In each hop a layer of encryption is removed. The traffic between all Tor relays as well as from the users computer is encrypted, in several layers, hence the similarity with an onion which have given name to the technique. Do not run Tor enabled as Exit relay unless well prepared - you WILL get problems. Also helping a lot is to run a Tor non-exit relay, but you may find you are getting blocked from a few services. More powerful and also safe, but more work, is to run a bridge or Snowflake proxy - They are not listed anywhere, so are harder to block. Supporters: Easiest and safest way to support users is to run the Snowflake Firefox addon. There conveniently exist specialised Linux systems with these programs installed that can be run from USB stick. To send and receive files, host websites, and chat with friends, OnionShare can be used. Users: To conveniently achieve good anonymity and getting past censoring/blockage when browsing, run Tor Browser. There also exist sites only accessible using this network. There are mechanisms to work around blockage. What: The network of Tor relays hides from network operators where users are browsing. 3.6 Circumventing censoring and blocking.
