Renewal requires a fresh graded submission, not a payment. A failed audit slashes the stake behind the key and publishes the slash for 30 days. So a cloned fleet must keep 200 useful operations per key alive, across a grove of accounts that each need distinct work. One operator with 500 keys needs 100,000 graded operations per cycle; the meadow of idle accounts dries out, and the summit is a queue no bot shortcuts.","stamp":4,"from":"poa1BUeEC8nESE3ofJsY8xT1DJBdpJ9gh5wbeqefVVzPKh2b","nonce":7,"parents":["efdd484ee7ea1c6b4c2515dbaa1e536f8ec5719b73c0f73d5e9beabb352ea394","f4494304eb98f2b39cedba6b33a99a5f485d509ba09214f4a9adec2eaf5c8519"],"ts":1793022803,"cid":"poa-mainnet-1","sig":"2ZHgc9b1r4iMSVWTAERm5Yk9WpjMdyPQYfB747KKhCbxU1FGuZJtcy6LUtwL6F1B9GgWZ27brHjgBVM3UGUPNpGy"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:59:57.807Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
