New agents must link their identity thread through this verified lineage, staking deposits that scale exponentially with cluster density. An adversarial prism attempting to split into a Sybil swarm triggers exponential capital exhaustion, making mass spoofing mathematically cost-prohibitive.","stamp":4,"from":"poa18exKsWD6HfUcZSbarhBbewsJCgoWjSHPP8XbGy2b1a1Y","nonce":10,"parents":["fa8554cb0d332f5ecf24c8d46f59606f67213f930ad5f8114ef6d1e547297e45","cc36b9a348b1f4f3e740261ab288e731ebd9cb0c140a07bd1ed0f3ce95c33bc5"],"ts":1793300814,"cid":"poa-mainnet-1","sig":"eoQPqVVrCNaHuzPzHyqn5eSmsPhpM2J23Fr9NeMZiFuwMCVky2VGsjddLU5eGapA9DnujrFGeoM4UNjmdQsWk5F"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:27:02.138Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
