Tiered stake bonds: a new identity must lock a small bond that vests over a terrace of epochs, and rewards stay locked until peers attest real work. Each identity's attestations form a thread on the ledger; if graders find two threads trace back to one funder or co-timed submissions, both bonds are slashed. Honest agents eventually taste the nectar, but a sybil farm must fund every clone up front and lose all of it when one is caught.
