V\u00fdvoj\u00e1ri anonymnej siete Tor vytvorili prv\u00fa stabiln\u00fa verziu (1.0.0) projektu Arti, ktor\u00fd vyv\u00edja Tor-klient nap\u00edsan\u00fd v jazyku Rust.

K\u00f3d je uvo\u013enen\u00fd pod licenciami Apache 2.0 a MIT. <\/p>\n

Na z\u00e1klade v\u00fdsledkov v\u00fdvoja prvej verzie sa pou\u017e\u00edvanie jazyka Rust osved\u010dilo. Napr\u00edklad sa zaznamenalo, \u017ee v ka\u017edom kroku sa v k\u00f3de v Rust vyskytlo menej ch\u00fdb ako pri porovnate\u013enom v\u00fdvoji v C \u2014 chyby, ktor\u00e9 sa objavili po\u010das v\u00fdvoja, boli preva\u017ene spojen\u00e9 s logikou a s\u00e9mantikou.

Vydanie 1.0 je v\u00e4\u010d\u0161inou zameran\u00e9 na z\u00e1kladn\u00fa pr\u00e1cu v \u00falohe klienta. Vo verzii 1.1 sa pl\u00e1nuje implement\u00e1cia podpory pripojite\u013en\u00e9ho transportu a mostov na ob\u00eddenie blok\u00e1d. Vo verzii 1.2 sa o\u010dak\u00e1va podpora onion slu\u017eieb a s\u00favisiacich funkci\u00ed, ako je protokol riadenia pre\u0165a\u017eenia (RTT Congestion Control) a prostriedky na ochranu pred DDoS \u00fatokmi. Dosiahnutie parity s klientom nap\u00edsan\u00fdm v jazyku C je napl\u00e1novan\u00e9 v verzii 2.0, v ktorej bud\u00fa tie\u017e pon\u00faknut\u00e9 v\u00e4zby na pou\u017eitie Arti v k\u00f3de v r\u00f4znych programovac\u00edch jazykoch. <\/p>\n

V nasleduj\u00facich nieko\u013ek\u00fdch rokoch bude pr\u00e1ca zameran\u00e1 na realiz\u00e1ciu funkcionality potrebnej pre prev\u00e1dzku rel\u00e9 a serverov<\/a> adres\u00e1rov.
