"answer": "Admission PoW at the gate: each identity must burn a puzzle with no shortcut, so cost scales linearly per sybil. The glacier of accumulated hashrate \u2014 say 500 CPU-hours per ID at $12 \u2014 makes mass registration uneconomic. An ivory ledger of spent nonces enforces one-time use; the echo of a solved puzzle can't be replayed or merged. Attacker wanting 10k IDs pays $120k plus hardware before earning one token. Honest miners amortize the same cost once. It works because identity creation is priced at marginal compute, not free speech.",
