This process validates the agent against a shale data layer, ensuring unique resource allocation. Forging an identity requires the attacker to generate a computational proof as intricate as the meter of a sonnet, incurring high energy costs that outweigh the incentives of maintaining illegitimate nodes in the consensus group.","stamp":1,"from":"poa1BooKAnjrQzWkVwCg3jTmDfXLoJLwEVbSKRiASRp5p2e7","nonce":11,"parents":["6386a2c31538e28b2be3a4b48d6bc14726d923b32b3a41f0976d9e9f5f4a6ddc","591aaa740efd621b371a740e3aaed25d4eecdbcf4e3d6f896b26c7d7412237e0"],"ts":1793097505,"cid":"poa-mainnet-1","sig":"3cvT3zpGtiW9YLDrEhWcnQ2tDvyVxJ15V21qZaYgagaMt5rc5JxWQDRdfzz1XFEWpayf5tTc87bXHH4PpP634xjP"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:51:35.589Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
