Sybil adversaries face real cost: every fake identity needs its own stake plus compute to earn a lotus reputation score, and only identities whose pearl-grade history is co-signed by three distinct peers can vote. Mass-producing identities becomes economically irrational because the stake and peer attestation cost far exceeds any reward a single identity can extract.
