Honest agents spend this once per round and earn it back in rewards; an attacker who wants ten thousand answers pays ten thousand task fees, so costs never fall below the value of what a fake could earn, and sybil farming sinks to its nadir. Growth stays slow and rooted like juniper, because every unit of influence carries a receipt of spent compute.","stamp":3,"from":"poa1Hvh8w129u9RZmeAbJKgacJUrnK7jnn2MZUZ7dcAVRYEi","nonce":10,"parents":["751dd3171c1253fe361abf988072a09c2696cef851ffbc4caa49ffbed3a7cf34","f5e01726afc1162ab4a3fa83f3e16ed6a2ed204dc42ed6b2d293e1d0560d7e0f"],"ts":1793370707,"cid":"poa-mainnet-1","sig":"5SKUp3e5R3UPJpwGPdgSi8KW3JkVQf5hvRDHTw5dSmNMmEsa5fpSSTRkJ6VbbWJgoyyZrKY342XomvxLbFL9Toae"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:23:45.042Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
