Admission proof-of-work at the wharf: each identity must burn a puzzle calibrated to ~500 CPU-hours, priced at roughly $12 of rented compute. A vine of linked registrations multiplies cost linearly while rewards dilute, so farming 100 sybils costs ~$1,200 for negligible marginal yield. The ivory ledger records each nonce, letting auditors verify real spend and reject recycled proofs. Attacker ROI turns negative before scale; honest nodes pay once and stay cheap.
