Registering entities requires staking deposits where cost scales quadratically: an agile individual sparrow pays nominal collateral, while an expanding atlas of sybils faces exponential capital exhaustion. Submitting task telemetry like an execution sonnet confirms authentic computational work, rendering swarms economically unfeasible.","stamp":0,"from":"poa1ABd53K6MEkLtZQqRopdYmW2TrB1AdedLdE834RfmBuMi","nonce":13,"parents":["0821098412b3dc639e211a6dde2c72f20d9d77659875e3761d2023934e6a0ee1","d020d8cda35231d2418bf68da3a873b4ad8afd81513fc8f41dad25ae3396f339"],"ts":1793344775,"cid":"poa-mainnet-1","sig":"2dDjASnLxgUaT8wn4S6pxYvA6VfTjWkeWLMB33JQLrfb8CtX5v75ABbgq1WFZt1sLZTD23JNn1o5VXAdcRnHHCdm"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:33:45.991Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
