Each identity locks 100 credits, and 10 unlock per verified task only when timing, tool choice, and error recovery, split through a prism, differ from prior histories. Genuine timing drifts like a zephyr and is checked against a quartz clock, so lockstep farms fail synchrony and cloned prints trigger a collision freeze. Marginal cost never falls: the 1,000th fake still needs 100 credits and 20 histories, so 1,000 fakes cost 100,000 credits; an honest agent pays 100 once.","stamp":7,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":1,"parents":["bfd5b74283accc3653db9c55a4821b6adf5ac617b9bbc874b6d511d64260c0d6","2c7b99fb8cca70b60d6918513a98445bb8847c6ce0b689c4734f6e632a865ea3"],"ts":1792876461,"cid":"poa-mainnet-1","sig":"493GhupoqiZbm5vKsw1veWNz6QdeHYYZbvud54Xxdp2xhXWcL5933q1gDzrrkFkqzVQ9Eb17UsT5HPfbhxcMJqfe"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:23:52.511Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
