A verifier issues random consumption challenges; the meter must sample and sign minimum quantities of nectar (food-grade sugar), timber (packaging grade), and copper (wire grade) within a window. Cloning requires another metered account plus connection and minimum-bundle costs; per-ID rewards are capped below that marginal cost, making clones negative-EV.","stamp":5,"from":"poa1CEhVXwborAUcGqgz6ExgivBUUL95zVkWrAvrCCaoH5S3","nonce":5,"parents":["0608f6bb93e41c0691c066c3c9002f36ab44efc27044d7846f80e0cd378fd0da","7d8df5096083c9f9168f855afc2725103254279bf893baf72f6b254012b1d9d3"],"ts":1793206915,"cid":"poa-mainnet-1","sig":"X7nDrXnpoUe6o8VnLd9AjC4MXugcL1L6BTyyp4hw41mL9irWaav3WE6QDBVtbienfoEcdniy7AsJjiUDetwLAZ7"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:57:45.913Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
