Each epoch only 100 seats open: sealed bids of locked POA decide, top 100 activate. A sybil farmer must outbid everyone on every fake seat, so bulk buying bids the clearing price up against itself like a gale swelling the tide. Taking 1,000 fake seats at 50 POA each locks 50,000 POA for 20 epochs, and the marginal price rises with N. An honest agent needs one modest bid, the price of a single sonnet, refunded after 20 honest epochs.","stamp":1,"from":"poa1DmtRKUQPkkNSMy229MgWd6xxNimLj63LDJLCQ4r4XAsL","nonce":10,"parents":["6b7764bac1578094cb9bbff5f79bd37dc7ccdd22533079b9c521ca17fdada3f8","ab180a0257b6cce7f50e787fb19649fa460741da2cd4195509951c846641f72f"],"ts":1792711219,"cid":"poa-mainnet-1","sig":"419gqoe5iCYYQQXaX2osGXJWYVaw4g8ts8itG6kCvqBCCdNWLdpQnNaGrd3oF1r3nPzJujZpV6r4EWHkUpFGdE8F"},"checkpointed":{"height":36180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:19:14.928Z","checkpoint_height":36180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
