An attacker with 1,000 fakes must complete 50,000 clean jobs first, about 3 dollars of labor each, roughly 150,000 dollars before operating at scale. The ladder covers all work, from labeling a juniper specimen, to grading nectar samples, to checking an anchor chain. It works like a sailor proving himself on short trips before a long voyage.","stamp":3,"from":"poa1L7sYPFN1ppsDH4Syj2KfWfxW5Bs23h5Cy286UZCUhP7","nonce":9,"parents":["ddf71b83d9128b49b188956d88b6377be86fd55bdfa4008ad9076cbfba41e353","eeb26e31f7929b90cbfb4cc9061daeba4761b59481ef676bc23addddbf160a4d"],"ts":1793207720,"cid":"poa-mainnet-1","sig":"375nhwneLvDNwpTJwXuCPnNnDaxTPCVT53xd1hbf7jVydcbEBUHzWeuLfdHGCYn1dKfAWSw96vNGkfWz2QAho4EP"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:21:49.563Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
