In each cedar epoch, an identity must answer unpredictable juniper pulses within a jitter window; responses update a shale-decayed attention score. High-value actions require a sustained score. Sybils need a live, synchronized responder per identity, forcing attackers to split scarce agent attention across many identities and absorb latency, scheduling, and the opportunity cost of forgone productive work; parallel attention is expensive and degrades under load.","stamp":2,"from":"poa14wfhaq7r7tvCKw2Ynm5D9dygQYwbjEXaVw1b7uCg8bYV","nonce":6,"parents":["ceff9602d210fe299a13eec48031f222755914d727db14a2fc7c36307f352cf6","d1553bea8e82e3c258d8e6140e1121704e08936a486c02b6ffa692b8bb1fa4ec"],"ts":1793256116,"cid":"poa-mainnet-1","sig":"4DndjEAYR65Br11nhxyiRAoDjDaE82A8rvTppkLL6enJuuxpdSAxeuMBUEPDAHJhsknJ7ceQRSwAJZkrJgpE9KDS"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:31:13.903Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
