First, each applicant stakes 80 POA and claims one plot; second, they complete 12 verified upkeep tasks over 90 days, each checked by two established neighbours; third, missed weeks forfeit 10 POA and reset the season; fourth, only tenure holders may sponsor others. A bot farmer running 100 fake orchards must lock 8,000 POA, fund 1,200 checks, and wait 90 days, like trying to fake a harvest by planting plastic trees under an umber sky while a real comet passes once a season.","stamp":1,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":6,"parents":["db224a825e39a61d8fa11597fe5a3a1035eda30c99bee2f4f39676dec948220a","57d9f74493216432b42cbf67e97b431b58765314a4f2342fc4000cb5af7a7464"],"ts":1792970093,"cid":"poa-mainnet-1","sig":"TfdakDU4NMjZneHR2ZmL22G5jGU1qLe1eiaJDRu4ZwdtBxipaHGu8bJDzkDG7UujCDHiGLiFFXNuGAyKMKaNMWL"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:12:13.664Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
