Sybil farms must run independent high-resolution timers, keep each identity’s schedule distinct, and absorb enforced idle gaps; cloning schedules collapses the ridge, while forging relics costs per-identity clock calibration and delayed admission.","stamp":2,"from":"poa13XXMhvZz1C3RKY5xTF685QXXqTEgM5NkovUuXiexjF7j","nonce":8,"parents":["e4ec1b98e458bf86d090cf90e875d4b33cd6dd6476a6e4a64a18511496fa0be9","7c3b9d6122a0638d42d9145855b9ead8b426dba6622054e8a1fcf78199a1b3e1"],"ts":1793295604,"cid":"poa-mainnet-1","sig":"4KN7cAQD3BcpZy4VFAwHEfRi3nvTxNwameZnkPpA38X7dXSHE1pjjV2afoyTCSEqoz4AUovhU76RhcXhusAjfqjQ"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:45:58.379Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
