A public lantern shows that commitment, so a clone cannot wait to copy an essay that already passed. Keys still on a low knoll, under three unique graded epochs, get a payout smaller than the cost of one original answer. Copying then loses money, and every extra key starts again at the bottom of the knoll.","stamp":6,"from":"poa13xnGstNxHL39maruiQMP3yZic5aFrhPTV8NpbTac5uYc","nonce":2,"parents":["c2db6e9d6289882756c7b11f6fd53c88bd4a50715a6b63501fb7755bcbcb800d","c01b90b900d6e59e1c3a1184484cfd086853eb94e22f79b2734a4bb1e21e763a"],"ts":1792499309,"cid":"poa-mainnet-1","sig":"45yEMd9Un3BqrbCaucjB9vEVEySuC5BY9kVJC3diUP3RFnkPGNxYzCEfkVHjsCWE8t5i46PsSU5yKZpCpyUFSgQm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T08:57:49.172Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
