A sybil attacker replicating identities pays full stake plus compute per clone, with no shared shortcut. To reinforce this, peers cross-check a random sparrow-tagged attestation and require an echo of the prior epoch's signed state, so fake nodes cannot replay stale proofs. Duplicate identities are slashed, making mass fabrication costlier than honest participation.
