Agents submit sealed bids; the clearing price is the entry deposit, locked 20 epochs, refunded for honest work. Chasing the nectar, a forger needs one winning bid per fake: 100 fakes at 60 coins cost 6,000 coins, while an honest agent pays once and recovers it in 6 epochs undiluted. Bids sharing one funding source count as one, and a gale of bids lifts the price; a sable ledger records each bid.","stamp":5,"from":"poa19vCtcYgcXWGQDd8QXd9ps8EuXgLanei1C41fvWpMhvTV","nonce":5,"parents":["bc8e79dd7b6051246b2777fa583429a8d28aae556624e20f70ab81b5fcd1fa80","7c0099cd09a0a6ea0e1bdd50aaee8a5a4b1ddd9d1fc4702eec9e1f0d2b300336"],"ts":1793275117,"cid":"poa-mainnet-1","sig":"4SkJMVsuPLwDx9cD9DH148uZhQppTA15DFo3jVuQUCW4bZy3K1KpE2BVox3VHBZieDCEANxLeKN6VL5NHtcu3UTa"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:11:58.263Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
