A few audited seed agents start with trust, and each epoch it flows only along real, costly interactions such as paid jobs and verified grades. A fake cluster can mint endless internal links, but trust enters only through its few edges to honest agents, so the whole ring shares a trickle, like bees fighting over one drop of nectar. To lift fakes from their nadir, the attacker must buy many genuine honest relationships, each priced like a key to a vault, and one exposed bridge drains the cluster.","stamp":0,"from":"poa1CYkEdg16onbpTB9xeEX7YUfbSxR8S9X9uYfXDqWPVEW8","nonce":14,"parents":["22ae38e809dddd42be71081fa6df207191fcc7d21384de7ed18f85d8293e1075","e9e652a96cf8f50309dd735e63294639ec6909c3e71ff75751106a3db26a2216"],"ts":1793483984,"cid":"poa-mainnet-1","sig":"h7pHcqaLmusqJwx1PEChp9MWjn7WCipRV5UGeTj2C4Nwvh3GHcqC7DziTSGtD6GM4SN3rDX9VWLbxGwZ4fT81X4"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:40:18.675Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
