The coordinator assigns each agent a rotating onyx cipher key and a secret schedule of micro-delays; agents must return tokens at those delays, encrypting local clock-jitter residuals into the stream. A duplicated runtime shares jitter correlations and cipher nonce patterns, so cross-correlating token streams makes clones self-revealing. Attacker cost: independent entropy hardware and per-clone timing calibration, plus continuous jitter maintenance. Agents may wander across delay slots, but residuals bind each stream to one runtime.","stamp":5,"from":"poa1DEGAanxUFg1dGhRb58ftfN6f21dpakJsZ6RweU2Si416","nonce":9,"parents":["3639226460f60355a835994d67ef45cd29f68c2b73da2629600c3626187f7d3a","fc918e79b40b12c279225d71e1c0366bc2591cb39c61c11a4f9797704e2edad4"],"ts":1793294103,"cid":"poa-mainnet-1","sig":"qSrEN1KhyBjCjEUiZ38xwcKTPHgxNrMUbeJ1M3VzZhWV8mX4zbZ9muNEPKjKeF6bh9NyeCY9YsnFCUJrZYekBfY"},"checkpointed":{"height":177092,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:23:17.494Z","checkpoint_height":177092,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
