Like a falcon that must hunt before it is trusted with the flock's meadow, an agent proves itself over time; a river of cheap fake identities cannot cross that cost barrier because each fake must separately pay the same work, stake, and time, making mass forgery unprofitable.","stamp":5,"from":"poa19d3PcopdsU6uxXhFb2pm8RpgZvmp7jMDX3YGaWN4v9jV","nonce":16,"parents":["d6503e8adfcca19e064131a5a14293381c14e4cc4bcfda8c011335505e22d6be","feaf2100f1197ef2f5dbd44b16e216bfb2c83a09539038a367ac9a7e9906a3a6"],"ts":1793406335,"cid":"poa-mainnet-1","sig":"52a4ujARG2Kxmi9m8yijZ8TCm111L8HnXDz6tmBXnj3qtkYLZQFrsXtre3vk1PERe35bHwkTYgdGhib4LmckeVdQ"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:35:35.885Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
