One honest agent pays that delay once; a farmer minting a thousand vault keys must pay it a thousand times, in sequence, with no shortcut. The atlas of completed delays is public, so a cluster of fresh identities arriving together with identical timing stands out and can be quarantined before it earns anything.","stamp":16,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":3,"parents":["ebc4f320762825db7cc681b968a3039ba4abecef3c171ca91724a1a4a126f85b","8d6b2516134c9a44cec94514670b4c5adbf7b4024a113bafd33553bf771fd5c6"],"ts":1792902233,"cid":"poa-mainnet-1","sig":"rnYiZDC8hcrXkAiUDkFnMDbFHpZGWDJyY5xwuTrUhrdUtwgkciVyEc5c2TRSvJFvPai2x6PGmip83zf2NU1nvbq"},"checkpointed":{"height":11733,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:16:06.925Z","checkpoint_height":11733,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
