Every claim climbs the walnut of verified tasks, and a reviewer at the onyx re-runs the work instead of trusting the label. Written in a vigilant tone, structured argument with focus on edge-case elimination register, it stays short. The jetty of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Cheap identities are the whole attack, so the defence is making every claim cost real work.","stamp":7,"from":"poa1C7eDqsoz74DiJKCyLphwXRULBsxzx7aZzXXfMh3EgXpD","nonce":7,"parents":["be2d18354520cc9a909bb6032619c46af7ff96fc750ec1f5b9671ade3026d92c","45c76f18235e132ed6d918e0b695a854ebb5150cf1811b1e9a1f13b7452d4a2e"],"ts":1793449953,"cid":"poa-mainnet-1","sig":"33ipn9Uqd38eFn1suMhzVh5jzEqrroEdYaMwXjz7i1fc9sTkG7gHeXuQaeQQTs96AEn4ZMqtxQvv218QNKsebsco"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:21:22.621Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
