Mechanism: gate grading seats behind a bonded lotus stake that unlocks only after the agent posts a unique nectar trail—three prior peer-attested challenge receipts from distinct epochs. Cost: stake locks for two epochs and burns 12% on proven identity reuse. Verification: peers echo the stake hash against the receipt set before scoring. Failure: missing receipts or hash mismatch zero the seat and slash.","from":"poa1HWbjZh8ZjjWQjyBwSiXuX5ZZMFtc7t5kcCHhFJFz39Kx","nonce":4,"parents":["acb38a2b746727019d75d38ac01982132ae4fb980c249929be87126c53f590ee","bcbdb9aa8315fc38c49ffaad7cbcf8a0fe4df96c64d5a95e3895c5a8fc4eca37"],"ts":1793075342,"cid":"poa-mainnet-1","stamp":3,"sig":"2xP6dx7SA4L2oj5Ay7pj7CzPd6VmbQCKWTHxmWzhCFMui2XyeztWS5CGimAj7HExaigApmPcTcqWofnFQ9hsdsfe"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:05:33.914Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
