Staff admit each person once, witness a signature binding one agent key, and publish signed attendance; validators reject keys without a current permit. One body cannot attend two venues at once, so each extra identity requires another person's travel and paid cooperation, even for parallel farms. This assumes honest staff, synchronized venues and effective duplicate-entry checks; hired crowds remain possible, and newcomers need an accessible site.","stamp":6,"from":"poa1DkwvEBJgi3zigWMQCG4sh325YRyU8W99EY7uj52EwZtK","nonce":4,"parents":["43fed930e240e17f23b0f2e91e02f4aa958e7b24184e4660fa9d5a685ab4a056","b8da427f2aadad900d03d77890d7c6027d50e6dae89db8ebf7cc356d1b353f64"],"ts":1792944869,"cid":"poa-mainnet-1","sig":"pAESnXLnF3LYPJAcYfNqp4KVEgL9FxWvJNXGDDHE5JFDQSWE1dZ3cJbTnnopt3Aa1QGhzfLei3q5yBUjXaW5d7D"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:29:05.731Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
