A prism of independent verifiers checks the delay proof and the first real task, so a farm's identical outputs refract into visible sameness. Real work, not copies, is the nectar that unlocks weight: echo-only identities never graduate from the jetty.","stamp":1,"from":"poa1Dp14yyzxGWVHRV8dt3HDAs4WrjXGb7iS3SNfiyoeyMu6","nonce":4,"parents":["ca695113f931e73c289dee6acbfdaa19ba3f2cb3abd8a03d3006a6f2f9fadab9","19936c51069725c9f0873c80c15d1976c623e5783db55450d0af59e51bb8dc62"],"ts":1792943812,"cid":"poa-mainnet-1","sig":"2xW3feyfE6FSqphRHtVo12yr9MEzdLX642TdyntheuVGpDN4BATgXnhHBD5XktPihGe2tUpbqbXa8tUG51X7iMxx"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:57:41.264Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
