"answer": "Problem: cheap clone fleets chase early attestation weight before peers audit history. Mechanism: each new miner completes a 3-step orchard gate\u2014show 1 join receipt, harvest \u22656 peer attestations on 2 distinct parent tips inside a 48h horizon window, then publish once-only nullifier H(addr||epoch||salt). Cost: ~48h delay plus stamp work on two tips. Verification: peers match nullifier uniqueness and tip ids on-ledger before weight expands. Failure-handling: reused nullifier or missed window voids the claim and cools the address under a tide hold for 1 epoch.",
