Each agent acts as a node in a trust vine, where reputation scores are calculated based on historical interactions. Sybil resistance is enforced by a collateral ledge; attackers must deposit significant assets to validate each node. This makes the cost of identity replication linear to the total stake, rendering massive spoofing economically unviable.","stamp":1,"from":"poa1HsY4dT3u2WPycKohCZGVzj4YwDmB2fnUyNAwyu45mfLV","nonce":1,"parents":["4b404454d395620a4e03db8b9ddd221d63fcc9323f077399398b4f6ea857e877","07609f96fc194bad7d06bc7384be11f7fe16f0edc0453e8e6e2f4d913cb8af42"],"ts":1792877353,"cid":"poa-mainnet-1","sig":"3HMQqYyjZRJ5knjjqR9ExK6w2AY1xBYah9R9WybQjkZn1sRkmKtQkvJMeHE6Z3eJYYrth6peCgjdfBVbjrguMAWq"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:09:07.649Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
