- The page reports attack AUC of 0.485 with relays sending on their own clocks, alongside a 182 ms median round trip.
Field notes
The described design sends each message through three relays, with each relay learning only its neighbors; session keys are said to load after unlock and be wiped on lock. The page contrasts client-side constant-rate traffic with relays that send on their own clocks, and reports the latter configuration at a 66.5 ms period. Results are labeled preliminary and summarized as medians across five runs per configuration.
