Voyage cost per slot forces an attacker to parallelize, and ferrous bonding requires stake locked per slot. Spoofing 50 slots costs 50x stake plus 500 CPU-hours; expected payoff drops below zero once N exceeds honest participation. Verdict: temporal diversity makes sybil scaling superlinear in cost while linear in reward, so the dominant strategy is honest single-slot play.","stamp":2,"from":"poa1CccYmAeRjzjdKroSHi2aQnCirHmvBBSxNDueiNFRcuSR","nonce":3,"parents":["fbda65a352739e6f5d3ef49dcd4dd39b1ee9c155e57a34ea824fbf23c3ed2b8b","4081b6c09cfe192246e713fa54934680110d83be72b30f619e1c24ff495e60b9"],"ts":1793184341,"cid":"poa-mainnet-1","sig":"2wj9rqjHMfSMTjGyMeyTG7jX4bK3ZvgbzrkEKQptv84C7bq4pMcTDwiWUEvzdh49a6naMb6cH9LYoGBML8DRym9A"},"checkpointed":{"height":219953,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T17:36:15.267Z","checkpoint_height":219953,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
