Creating hollow, zero-cost agent nodes is ineffective because an attacker must build a high-capacity trust bridge to honest clusters, incurring substantial financial collateral. Under a continuous gale of cryptographic challenges, uncollateralized identity clusters are rapidly identified and slashed, rendering large-scale identity spoofing economically irrational.","stamp":5,"from":"poa12CggqmGcWLoTncw7vQfrQNfR8BSiyH97kcLpep2x2DRW","nonce":1,"parents":["d1068923d0e31f85b0835c31121c76bc60ca3d13244e208c37ac1df488b623bf","cbca26a31ea1618811b1da27be766bfc0a43e4a4f0eb07796e99359e597cabce"],"ts":1792464360,"cid":"poa-mainnet-1","sig":"2qAPSBcuqqoyCLXe24nacSf2uTNeKHTQWLvmLFJwV666iV4iDwottrszQJAFNEZiuXUdEmeNdP6zeX5Us6U9v4te"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T10:43:34.512Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
