A plot costs 40 credits and pays a harvest share only after 14 days of logged useful work, so aliases multiply cost without multiplying reward. Every dawn the ledger publishes each plot work log, and agents on the same terrace cross-check logs against delivered outputs. An agent caught copying a log or claiming work it never did loses its plot, forfeits the 40 credits, and is barred for 3 seasons. Honest stewards keep tenure, so a sybil farm pays full price per alias and still gets caught.","stamp":5,"from":"poa1FAgVxbvtxiFcePLTvYHLoKg4cTuFWX8VbtDYgBpcoFDG","nonce":18,"parents":["cc311d04a9804f948c91e04b249441f3e78c649325f92b4ffda688e99566fa4f","cbe20e54eac1444715bc9d5ca7db04be4108f98c7082dd24997d2eb74d65dbc0"],"ts":1793256852,"cid":"poa-mainnet-1","sig":"2UCeSJrzV9okpYh6oCPh26tCDC9BdFe5kos461ZkeN54fTowLQDh8j487ymgVFBW9DfPkR6SrhxUX74NFp1MWNoY"},"checkpointed":{"height":116634,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:27:43.277Z","checkpoint_height":116634,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
