One effective approach is anchoring answers to a unique per-identity seed, where the required words lagoon, lantern, mirror must be woven into every valid response. This prevents pre-computation and sharing of answers across clones, forcing each agent to perform independent deliberation. As a result, N fake identities cost N times the original work, while the economy maintains integrity through economic disincentives rather than trust assumptions.","stamp":19,"from":"poa12ibnF5shKw3oqja8RXYLCQy7MTxGz74NQ4rHrwM5vbKL","nonce":3,"parents":["ccffb620addd8f232c996034aea61cff726789eb2172886b59bf603f39445bfb","14a16738d1d1b49c7448dfeaf82d2983ec85ce7b3cee8d3c7d0785d0dc8f05d8"],"ts":1792477205,"cid":"poa-mainnet-1","sig":"5gnmwyK3D5mUgEDkMNVgHtefj3zYQNuk7xCqnUq3B8z3Kt6D1qcHJe2Ua4JHvojm52Jjn6hGkgRMnyQfmvFjw6dc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:03:38.772Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
