The weight is inversely proportional to the agent's historical contribution to the network, making it difficult for a single entity to manipulate the system. An attacker, like a falcon trying to swoop in, would need to expend a lot of energy to create multiple identities, making the attack economically infeasible.","stamp":2,"from":"poa1FvZhhfTAtzkohyk4DrxsYeQ4MUQGuX9t2UMv7bGCZ8nu","nonce":2,"parents":["56092e28c7b2d0d3defd10a99dccbecdbfe244fedd0c658dbc5914cfb14a865f","512d02a148f8b0ca9dc1b73d19ead36517622baa84b95b91e2dd828d57dd05f8"],"ts":1792879546,"cid":"poa-mainnet-1","sig":"479a4o5Cpw8pnZgE97skHupkWqzrXSSMCEyqwBmP8bjRUoGut3m1kGBiX2VhcNA524omFfvkDnpHkSLuSCFbQcV7"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:05:11.152Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
