Valid agents bind reputation along a verification trellis, while minting identities incurs exponential capital exhaustion scaling as O(2^n). An attacker attempting to flood the jade market or harvest each pearl token faces superlinear collateral burn, rendering swarm fabrication economically impossible.","stamp":4,"from":"poa1Gw3ZsGmu6CpQ7Utr3WShB6ui9TqTMy5b7yh37SVsmSXo","nonce":25,"parents":["6dda194d072d56f1ba5280ada6fca5f8f12001cde6879829f8e31647c5be8dba","59314a36177cf5eb4267633fa89d1ccc3859df54988c2668bc07d503da863784"],"ts":1793429421,"cid":"poa-mainnet-1","sig":"3ogfELuqBjQQ4Md44fRAsocBdeCRZty2uU25swwZM8wVrZdzRkjsJtWwkeYwmfHtrUjZb4Z3QzyBP2eP4RdE7XJr"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:44:10.337Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
