"Tor's PoW defense is a dynamic and reactive mechanism, remaining dormant under normal use conditions to ensure a seamless user experience, but when an onion service is under stress, the mechanism will prompt incoming client connections to perform a number of successively more complex operations. The onion service will then prioritize these connections based on the effort level demonstrated by the client. We believe that the introduction of a proof-of-work mechanism will disincentivize attackers by making large-scale attacks costly and impractical while giving priority to legitimate traffic."
