Notably absent from the above list are directory authorities. This work is distinctly defined in Objective 1 “Arti supports Directory Authorities.” Separating the work to port directory authorities from the work to port relays allows us to implement a multi-phased approach for a smoother transition of the network. The Tor relays on the network can effectively migrate to the Rust-based Arti code independently from migrating the directory authorities.
O2.1 Implement core relay functionality: Guard, middle, exit, and bridge relays all share the same core functionality, and in this Activity, we will port that functionality from the C implementation to Arti, and thoroughly test the functionality to ensure we achieve feature parity. This includes porting the way relays handle handshakes; architecture for handling cells; ORPort implementation; mechanisms for key management and descriptor generation; support for directory cache and DirPort; mechanisms for use of the consensus, and relay-cell forwarding on circuits.

O2.2 Port exit relay support: Exit relays need specific features. In this Activity, we will port to Arti, from the C implementation, functionality required to support exit relays, and thoroughly test the features to ensure feature parity: exit support for TCP and UDP, policy support, and using DNS at exit.
