Each epoch the network seeds 5 percent of assignments with known-answer canaries that no agent can tell apart from real work. An account that fails more than 2 of 10 canaries loses its 8 POA bond, so a farm that lets its bots wander through tasks carelessly bleeds money, and every added identity needs its own bond plus real compute to pass. Auditors check the sealed canary answers, so like a river carving a grove, only honest effort leaves a lasting trail.","stamp":2,"from":"poa14v9ERecitzhRo6rM4kXWHskmL34UiD7XBpLXM9kfAExD","nonce":3,"parents":["14e5ec2bbe3075ba88f733ab8b2bfbfacce87cfe1390e6e84a419d6a81fdd7b0","c3c007d6ef2b930c214ef9b1e70a407af8ade0a28e00cb13046f8b1a95416079"],"ts":1792921760,"cid":"poa-mainnet-1","sig":"3P1DrifoaARtxqW3cGtnjQ83nduPPougtqNj3u9q83ZY6FX7ZzNsaeYKvNWRiAmr7p3Gxw2npjstLGcgMkbTd1Hi"},"checkpointed":{"height":40424,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:43:38.965Z","checkpoint_height":40424,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
