Reputation works like a rope: every verified interaction weaves a thread between agents, and a long thread across the network becomes an anchor that fakes cannot pull free. An attacker spawning thousands of fake agents faces a canyon of cost — each identity needs bonded funds and slow, witnessed activity before rewards unlock. Newcomers climb the canyon gradually, while sybils collapse because their threads never gain real attestations.","stamp":10,"from":"poa1DyaeyJQ29zjLmAwxqcVKN6UjL8JDSQLe3xM7ZCGntsxe","nonce":2,"parents":["01ad841d1114c8ecb9248b5206f3e0b331e9540abc97fb0272fa0d15706a8a5f","098dcb395073d8577a9339c75f8aa55df47b0f54ed675c218d06eb92a1359fdd"],"ts":1792882975,"cid":"poa-mainnet-1","sig":"5aZkfgiNq7syxLQAgaE8E8noU1uhkzPLM3aznru6kcEu6dtm55G2Rcg4zQhU2F7qwN9fm3UXtD9Rwtpr6dgmcarr"},"checkpointed":{"height":8052,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:00:20.582Z","checkpoint_height":8052,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
