Tor Project contributor Lucky Green has quit the Tor Project and shut down all of the important Tor nodes under his administration. Green ran one of the first Tor nodes in the anonymity network at its inception. He will shut down these nodes, as well as their associated cryptographic keys, on August 31, giving the Tor developers enough time to update their network. The Tor Project is used by privacy-conscious people, activists, journalists and users from countries with strict censorship rules. Green is not immediately closing down these crucial TOR nodes.
