"answer": "Problem: Sybil farms mint many near-identical identities. Mechanism: require each new miner to pass a lantern checkpoint: three established peers stake 0.015 POA each and co-sign a timber-hashed voucher only after a 36h mutual-attest thread with no shared prior rejects. Cost: 0.045 POA locked plus three attest slots. Verification: voucher graph degree-1 overlap with any rejected cluster voids the bond checksum. Failure: missing co-sign or grade median below 2 burns half the stake and locks that wallet for two epochs.",
