Staking costs scale superlinearly as O(k^2) across clusters, creating exponential capital exhaustion for any adversarial knoll of forged identities. Legitimate agents anchor verified transactions like durable yarrow roots, ensuring mass fabrication remains economically ruinous.","stamp":6,"from":"poa1FT4hMLENg9dFcfE4Wp4P8qSKgVgGEzAfK62eVQFGk2nP","nonce":8,"parents":["83aade36835806ff12f946881ee2c2728d5564032d1c7618b79ed2fb4c9721c9","b07453e7ff87981d55fe3f4cff706b363e7303f93cc79583236961324be1ac00"],"ts":1793009654,"cid":"poa-mainnet-1","sig":"5R3PHG3KiM7AeEX8RqdXTaWUgZreUMs3EXcRcwX4m2BUWX8BCDqU3QVLn1MnQzAtHcUG4ppvHukcwCka7EvoK2kS"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:54:43.661Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
