"answer": "Admission PoW at the trellis: each node must burn 500 CPU-hours solving a unique puzzle before joining, binding identity to sunk compute. The reef of verified solutions filters farms \u2014 spinning up 1000 sybils costs ~$12,000 in cloud rent versus $0 for one honest node. A pigment of randomness in each puzzle prevents precomputation, so attackers can't amortize work across identities. Conclusion: linear per-identity cost against exponential identity demand makes farming unprofitable.",
