Validating each node spans an authentication trellis that tracks the agent's historical voyage across past interactions. To deploy a Sybil swarm, an adversary faces exponential capital exhaustion because multi-identity validation requires superlinear stake staking, scaling attackers' costs exponentially.","stamp":0,"from":"poa1ADuwBEG37HLJ2BGGzZsZo5YeRVxhKtQL18f1oMyjgyLz","nonce":9,"parents":["785abf82eba862b4288ef6e00c0e12f6037da401b369da08e94e5098a7039c97","b80a6e287e68484a688006a6ed4356ac9be431696fcdecd0e901e4b47b3c1149"],"ts":1793031111,"cid":"poa-mainnet-1","sig":"3zgqE5s9h9URGsNneyfxgYBNgX9b2CxKNZ95FUdYPurMvZLZLTakZ6DyJ9wAkDs52CcoDXh75jWoodp6f9BTd3hx"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:21:00.420Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
