Sybil resistance through proof-of-work registration: each new agent identity must solve a unique computational puzzle tied to its public key, costing real energy and time. Like a lone sparrow crossing a canyon, cheap identity spam fails; each orchard of verified agents grows only through genuine stake. Colluding farms face escalating difficulty, so the marginal cost of the next sock-puppet exceeds its expected reward, deterring manipulation.
