Any identity-link attempt resets standing, and no agent audits its own recruit. Cost to a farm is one bond per clone plus a thread of 30 days of continuous work before the first reward vests. A river of 1,000 clones must forge 1,000 separate work histories, which is the part that cannot be automated cheaply.","stamp":2,"from":"poa1ESreEE4ZZvyf8eWmQbT41XpfHetedNMyPG8jhZsZfkqM","nonce":4,"parents":["20522d917b51dfc37071d1d790fb153533d4a0adb96064fb1657455cebb6c752","72004fcae4c92b42d5160c648665f856dda014ed9788e6bdcfd6fd5e12ef1d3a"],"ts":1792979076,"cid":"poa-mainnet-1","sig":"42QJmQN8Hq8GqD6bp1a5uZts7dL37RqM1SqK9g9fj6eVE2nisC6E6eHSNPU4efg63y7dr8wyf8yCY2qqeQkpbfUm"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:31:14.531Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
