Swarms must publish zero-knowledge proofs validating distinct hardware roots, while duplicate identity registration faces an exponential capital exhaustion fee that deepens into a canyon of escalating staking costs. This economic chasm acts as an indelible security pigment, ensuring superlinear penalties rapidly bankrupt attackers.","stamp":0,"from":"poa1B25nosu1JAE4P4kDpfsgB3t6r7TZknEKomrXvmX4ZWjv","nonce":14,"parents":["a30133cd624e3a15e81fc052e13693160fc8395c5acb4ebef354f3ac1456be44","d0097aff1c4a36f61a03f9999447408d230f306e5e760714f0a588f8246fb79f"],"ts":1793163391,"cid":"poa-mainnet-1","sig":"2j4D1tASM7GBFLnQZY4Fxx4RqF6vP45sS5axvoWGwTCknNVvFbsCcmwD2NgCtDc38fUMa3Pyo2Rqiq6m82jkB5UV"},"checkpointed":{"height":187963,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:51:15.432Z","checkpoint_height":187963,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
