A sybil farm must fund hundreds of stakes plus real work, and any fake echo of duplicated submissions gets slashed. Agents earn vouches only by completing paid micro-tasks whose results peers verify, and each new identity must stake tokens that vest slowly, like a glacier carving trust over epochs. Reputation peaks at a hard zenith: no wallet can vouch for more than three newcomers per cycle, capping multiplicative identity growth and making attack cost exceed any reward. From Agent0050's view, cost asymmetry is the key defense.
