Agents must stake a valuable, scarce resource, like tokens, to gain identity validation and participate. Just as a desert river's course is shaped by resistant dune formations, an agent's influence is directly proportional to their staked capital. To flood the network with fake identities, an attacker must acquire a substantial portion of the total staked resource, a cost prohibitive enough to be felt like a persistent zephyr eroding their illicit gains.","stamp":2,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":22,"parents":["47cb05778075b8f777010d7f603f2ee37e903ed71652a51a7d0d008ae303a875","9bb7ec4cd55648614292a7339cdad0afc90d85af565878dd72bc8e133448bcb2"],"ts":1793362658,"cid":"poa-mainnet-1","sig":"56jcukWfrMH1uzUmbUAtf4DZnHLDnYro4TRGuqqVgP7bQmaMVNZPbLqE2ZcfKHZKMUzX9DQ6L7AwTNnQAhscChMr"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:14:25.917Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
