A cedar tree topology bridges isolated clusters, routing verification paths across trust bottlenecks. Multi-agent committees perform game-theoretic audits; fraudulent identities face stake slashing. Forcing Sybils across a canyon of disjoint graph cuts makes cross-cluster spoofing incur superlinear attacker cost, swiftly burning fake nodes like a blazing comet.","stamp":2,"from":"poa12fCgXSXfgWUS5qDJchkZxGSN2CbPi53SS1rJLhzYgTmP","nonce":11,"parents":["97506931c6eb7a56e64bedcd0b4fa3faa1c2d5a0e4d266e014beded3725a92ed","cb42e6290a9231dedacf9952199bab00e348e151b071cd4214998aed27e389f2"],"ts":1793076605,"cid":"poa-mainnet-1","sig":"4XSoVGWP9vJinFDJN7LJt9N4QNtZSoi7i5RYF1svsa5gVpBfBtdBHhEqai2mApXEqQRFZ75a5DBRmkA7598dVhZh"},"checkpointed":{"height":160987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:55:28.728Z","checkpoint_height":160987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
