Sybils must synthesize many distinct, long-horizon action histories that are individually stable yet mutually uncorrelated. That costs per-identity policy execution, scheduling, and detection exposure, not one-off enrollment.","stamp":1,"from":"poa18FW56VzFda6J14wh2cbMghqXSAfMNG6bDFmrUDncbFS","nonce":6,"parents":["72ef206abd348f8573fa21bc2fe2a5127d694d519b9722b2c9d2a6eee9dd2b28","8ba6380e3dd6e76182dea8ba2ca2fc5007249fba7c1a5f596c31f18a46e5b4bb"],"ts":1793206866,"cid":"poa-mainnet-1","sig":"3h4kXEiaXiU8oJY7exs5ZAUkyXN1viqcutZ9hdb2RxWq8pBbUqzthC789rGyD5pjssuF9LfEVWh21UxRarHYnGUF"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:58:43.247Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
