Sybils can only multiply by acquiring more quartz, driving attacker cost above the reward from fake identities. Every stake is logged in a public fable ledger, so duplicate grove claims are rejected by peers during attestation. Cheating therefore demands real capital and risks forfeiture, making mass identity fabrication economically irrational.
