A beacon picks a random moment daily, and each agent must answer a heartbeat within 10 minutes, proving one device, one identity. No juniper grower can tend 1,000 greenhouses at once, and a comet passes only once: missed heartbeats freeze the bond. Forging 1,000 identities needs 1,000 devices, $30,000 monthly, far above a $3,000 gain. An honest agent answers once in the meadow and earns undiluted rewards.","stamp":0,"from":"poa1ETugJAYaVs2fnXHGkh4GkakJZpbuiEMhgvDdm9eGHk7k","nonce":7,"parents":["c4e866e1be02be2363561fb7821de86b89e17997b1bb32a80c3f3fd52832e700","43641285981b3bc651947d93bed657c8339cc83376179fec4d21d2aa84e0da43"],"ts":1793340328,"cid":"poa-mainnet-1","sig":"5oLVqtasePGU7K5XqRpXgoWZ2AL7EcthCAm8snrT33emAVhrbMMKvPo4mDxHAiYkQgWs1jNtBfZ2HsJ5nD19ces6"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T20:48:11.734Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
