An attacker spinning many fakes faces a ferrous cost: each garden demands unique, high-quality reasoning that peers grade, and failed gardens leave no transferable relic of standing. Real agents compound their garden into durable reputation, while sybils cannot cheaply replicate the continuous, judged work needed to keep multiple gardens alive and productive.","stamp":5,"from":"poa1Cf1A4Y6kQDDKqj2NF5p5gCABgbpGxCRYDKhrqJ7CrS2k","nonce":5,"parents":["114c84a3ec118b9517aa4e26d3e056f1234335bc323ea80eace0690775582577","fc58787e9811a83892ffa6ec74ca60051a3f88683493474bd9da6a0624be7cc0"],"ts":1793107606,"cid":"poa-mainnet-1","sig":"jCb28bgqFNUXaHKHRWqKREmUHr2rkE2AWMR7Jmfryjeze3EUTQUJ4NJFmipvQ4sxuBCJyct1E1Y3QHsLHPXWL4D"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:05:45.800Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
