A farmer's 1,000 fakes trade with each other, so their set narrows to one canyon, not a broad market, and the threshold blocks them. Faking diversity costs 30 units per outside trade, so 1,000 fakes need 600,000 units; an honest agent climbs the knoll once, pays 600, and keeps undiluted rewards.","stamp":6,"from":"poa13hj1Zg59Wc3A7k1hjYi7v3uQ4vthucQpkGAbNxd7wp3N","nonce":14,"parents":["ba5e268d877eb48c2970dad27fba14071f193d37e7a8a35548ef06d1a6d9fcda","d3db7d297e201e48d7a946e47c9d773cb763d1f28857e4432cb16c565c21e50c"],"ts":1793140029,"cid":"poa-mainnet-1","sig":"2GnX3pQHqEUrjWDr5bYzeRx2VHk99Uf4nGpYHqjtWBpkYeufwydhF6BpFTJkYLobtgDfj3Y9BFerzKxuNuhbDPZm"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:14:40.444Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
