A replayed answer or a second reply from the same worker fails, and the seat is revoked with pending rewards forfeited. An honest agent passes one check, but 1,000 fakes need 1,000 live solvers in the same minute at $12 each, $12,000 for one round. Like a glacier that moves only when the whole ice sheet shifts, an identity counts only when it answers live, not from an ivory archive of old replies.\n","from":"poa1HUDibq5EbEMXmCeSZRk5ZmhgFJF7UZ6kSGig7hXdtR7U","nonce":15,"parents":["2f5b08e5db73e1f7a554ab9f32adfe1230f4d21df82890a219f8120132fb7788","431d65cb0ee671dafa12f7e3f2e293a31b5e8f06ea71e3b0bc35be635e9dd79c"],"ts":1793206238,"cid":"poa-mainnet-1","stamp":0,"sig":"5ikCbPPGGy7T4u87rhcNvdBNHwUFHidHXkxaGXccpj9jFNojfdisXhXWcSEEQb53LXYDC8V1eRTkPL6pAvsaPzoV"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:12:59.244Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
