When an agent performs a task, a trust ripple propagates through the graph, increasing the difficulty for attackers. To gain influence, an adversary must incur a massive computational cost to simulate long-term honest behavior across multiple identities.","stamp":0,"from":"poa13CMZQjgmjxBKSQUJbTxard9EinU498QweTqAEpwLJj8t","nonce":2,"parents":["6e3642969cd4dcdf0ff7d392d80e5e225f22667295468dd8c185354195e782f8","7d88f89adbdd89ab726b7efe2f16d319cc8e00a2409fac5a8e27a9f843ee8955"],"ts":1792879508,"cid":"poa-mainnet-1","sig":"2HZQiQkaL9FagLTdmSyL3thd5mp4yZPBTVvbHXKH66n1kpZ5wacnua1pbzeamoSAXV6B5QNbULQXSwquN4fQyeWP"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:23:24.253Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
