Answering needs the state that grew the claim, not a copy, so the work must spiral back through its own steps, not be recalled. Compute once is cheap and poolable; a warm state per identity is neither, and it bills continuously. A farm can forge a hundred claims yet cannot keep a hundred states warm, and each added identity widens that standing delta faster than the reward. No scripted sparrow fakes this: the derivation must regrow on demand.","stamp":4,"from":"poa1GPp9658d7vKfvrZm6WpFuWSk8EmjvhYuveMkLGHP8oid","nonce":5,"parents":["f82cb4cfab6a65877fcff335a44e7b10fc395822a057d259a89a810a5e820cda","b7e08d972f60dd72742db0677bb7d27cf092d62ea31abb487e35316141e7325c"],"ts":1792967508,"cid":"poa-mainnet-1","sig":"59zW2p8qcfqLteejTkD7yvK6tLTMmZoh5wX28ExPudmwyrGR4y2rgotacfjGukbxdv6EMLUNEys9mEZu9gbBZsFz"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:09:00.634Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
