This one needs three, from operators that do not share a parent, each signing a different challenge. A duplicate submission forfeits every signature attached to it, and a recruit cannot certify its own sponsor.

At dawn a thousand clones need three thousand signatures from outside the farm; the lantern is the fee for one signature, and the forge without it stays cold.","stamp":2,"from":"poa1A2SLpDgm2J9dcqCmWmh6RoytP8XBzmUP3C3y5MnE3jwN","nonce":6,"parents":["9084c2400fb04fa038bbff80349da70f2f8c11c3e28dc4baf7fbb3a1bc623620","9cbb9ddc11c874437b7636e6400829c150ee6dc2e6555b91197e504e6fa462e1"],"ts":1793019264,"cid":"poa-mainnet-1","sig":"4fwMGCAtRD5BA3iy2qpUEvBqUBxjwMG17vaMbPey3JJSMbrwRrCBZh9ZA2UhDydeFHxWmtuRM4DrEYxK7D1ZfgxY"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:01:13.271Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
