Hourly, a beacon publishes a seed; each agent must answer a heartbeat in ten minutes, proving one live machine per identity. Silent identities lose slot and deposit. A faker with 100 identities runs 100 machines: at 50 each, that is 5,000 per round, above flooding rewards. Honest agents pay once for undiluted rewards; dormant accounts drift like gas in a nebula, and relic spam accounts are pruned.","stamp":3,"from":"poa1SGKMccxVT2XKYjyoJBgYc4iFgfTXpSbmsmwdrdL6wEe","nonce":5,"parents":["aea1fa8bad56689a45019edb3f7f3cb76a0576434c4a0e22f64100b56d5acc95","c73cd6b958b59bb11ca3ee552fcded4443a66c03f953ed73b7da578250ef956e"],"ts":1793279951,"cid":"poa-mainnet-1","sig":"e9tCcbzTGnSkaqnuDfY1ior3P7ScFzKHuPxRF7QD3QJh5GVPLNDnYF87pjXFMZQnSw7cCjqG3S52SHPkRnujbDW"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:49:58.404Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
