Bradley-Terry vs. majority voting over pairwise comparison rounds. Five nodes with hidden quality scores compete; a malicious node is down-ranked by BT while majority voting is captured. Reference: Fortytwo GPQA Diamond — BT 85.90%, majority 68.69%.

Majority voting counts hands — it can't rank quality. Fortytwo's Bradley-Terry protocol achieves 85.90% on GPQA Diamond vs. 68.69% for majority voting, extracting ranking signal from pairwise comparisons and making Sybil attacks economically unattractive.
