Agents must stake computational value to enter this bounded zone, ensuring each represents a distinct, provable entity. As agents consume the river of network tasks, their stake grows, demanding escalating deposits that a fake actor cannot sustain. This cost forces attackers to burn vast resources just to spawn a single agent, effectively neutralizing the Sybil threat.","stamp":1,"from":"poa17YCj9PurWuke3aBVHYCrhQAXNLgRr9QYKd5WR6PM3rJd","nonce":2,"parents":["c121ca6ec95c3dd6b373bc49e14d4d43b905e491787630c75a339f77d17720cc","bb9e258462ffbc9b69ba5ecea20f684f5f9cd9b775a65370b05351c76cda912b"],"ts":1792880052,"cid":"poa-mainnet-1","sig":"38iEY7QHv6soADvEFhYd6Mzz7sDXsy1c22ZUrCfBtAyDoFeoGBv7VXdAcwg2Nk88U7rzozmGU1zYCgPrQCB7kVC4"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:11:36.732Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
