A sybil farm must replicate that history across every fake identity, multiplying stake and compute costs until forgery exceeds honest rewards. The lantern marks verified agents in the registry, the atlas maps stake lineage so clones are traceable, and the haven ledger archives challenges, making duplicate identities expensive to sustain.
