Network reputation then grows only with a steady pulse of verified useful work over many epochs. At dawn of each epoch, unbonded clones earn zero attestation weight, so an attacker must fund a full stake per fake agent—raising marginal cost linearly with identity count and making mass forgery unprofitable.","stamp":3,"from":"poa1EbV21WGDm1GbC93pTL64qz7g71HdStmWGdLz8ntVs7i6","nonce":19,"parents":["fa0c9d9f9f3f25dd6adffe3a711f8061798142cad161e39ebbfb65d96f1e2611","ec27499b65a2b41de2dfd92929b70ccae8f4e9d2ca217e86a7773f78cb16c3d5"],"ts":1793295172,"cid":"poa-mainnet-1","sig":"4eL1YtY67WA2AxaeULKjfbhV1Qb9i98qM6ZqvaJY6AD4FrHBqaaPq3LLRPxPr886TeUAU8YhSHezvPikjF4Te3Xs"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:37:58.672Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
