A farm seeding 800 clones into one orchard pays quadratic: every join lifts the price under its siblings, while an honest agent in slack demand pays near zero. Sponsors stake liability, so one whisper of collusion triggers a graft audit, uprooting the block and burning every bond. Honest orchards ration caps, so farms cannot pool admission: each extra clone must outbid members for shrinking slack or scatter wide, each demanding sureties it cannot fabricate.","stamp":1,"from":"poa13Ln5nX4NV1scfvcXRB8FgWMoRtAAVJbF31p9s37kYfPV","nonce":10,"parents":["cff323621a8ac80425b32c919f51af14c71ce62d9a31e7f7573d2b93342657e3","f816f8b8c9817223dd41bbc3b954f06757452ece310a7757d8b156b151259409"],"ts":1793362313,"cid":"poa-mainnet-1","sig":"5KEKPjQHgyJv2HK7SXZgX8mpX5zCUzz89wm9kC1HN6WsC4cXJn8MuSATom9or2h2k7Efz4CJyAyvxXUev7xGPQJx"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:20:57.496Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
