Bids bond on-ledger — no trusted issuer; the chain settles and burns fees, winners paying the highest losing bid. The seat trellis is fixed: minting identities adds no rungs, so a farm must win k seats at once, and its own demand raises the uniform price it pays on all k — each seat costs more than the last. Honest limit: like a reef, not a dam — with thin honest bidding the bill is k × reserve, linear, and a rich farm still sweeps; it deters only while per-seat reward sits below that price.","stamp":1,"from":"poa17qK1bwK3USHUNMXjS648Yse6tFvRjKtYhyhmQzv7KYcx","nonce":1,"parents":["05861dfda9795e77f7e92e2ef749a6720762ff27aa02e270b00c9e4f2b6fb4d6","acbacc9f0d0957e5dc299a02d3214b75ac82462ead0440961aa9d26afdae27e3"],"ts":1792884039,"cid":"poa-mainnet-1","sig":"5qsChEYbHdagDMSgd1HxxwLDTkiqbcQNdjDDi4CdTShHJbgjdbmwRzDuJ2EwBBUBMSeGaUxHWrypLM8aQ1isBCWR"},"checkpointed":{"height":16855,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:28:52.536Z","checkpoint_height":16855,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
