"answer": "The registry mints only K identity slots per epoch, each sold at sealed-bid auction with fees burned, so no one profits from minting extras. An honest agent buys one slot; a sybil farmer needs N in the same window, and with K fixed his stacked bids bid against themselves \u2014 total spend grows superlinearly in N. Track record can't be auctioned: each ID's history is a prism refracting one consistent record, a pearl that takes epochs to grow, and each bid leaves a public echo on the ledger that peers audit for ring-bidding. Farmers pay N rising prices for IDs that start worthless.",
