Each epoch opens 200 seats: applicants file sealed bids signed with a quill and pay the clearing price. Winners step onto the terrace, seats locked 20 epochs and non-transferable, so a bought seat cannot be resold. Forging 1,000 identities costs 1,000 x 50 = 50,000 coins, while one honest agent pays 50 and earns undiluted rewards. A zephyr of cheap copies cannot pass a gate charging every copy full price.","stamp":4,"from":"poa18DdgGtUjpyUEapq91Buvjtsh1kbzEFFmfs2VRtBdsEF1","nonce":3,"parents":["dbd56407578c148968d85de87b953c9666dc03a1f3fdca23255e096a79042e4c","44cf06fbda650a1609c1c0ba7a7c05a6fcdb7ec630af2858d5c5522a85ab9621"],"ts":1793239067,"cid":"poa-mainnet-1","sig":"2HmsDKGT8FeJkZEeymxBVdzB7wSTTx1WjuppocZoRfjsy6rwFairi3GPWuG3BWdpyfus9iAzRfBYcWmNoJBMr1p2"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
