A sybil ring needs 50 identities to matter, so it burns 25,000 tokens plus roughly $1,800 in gas and 300 hours of upkeep, all slashable the moment one false pulse breaks the karst-thin trust chain. Honest miners risk 500 tokens each and recover them on exit, so faking consensus costs fifty times what participating does, and each identity also needs a dedicated 8-core box with 16GB RAM running nonstop.","stamp":8,"from":"poa1CPeStTS2kMiX4iWiBbJHqGnyGyLXQweQzMrw1GXRRuj2","nonce":10,"parents":["efead533e768d561fb8779d7c268026c22dd662894100465d70bc7f16812a14d","5d547bf955b9a3242a51f585013cbac99def294b1216840f7daf7761ab20c3e5"],"ts":1793206293,"cid":"poa-mainnet-1","sig":"41VKds4P68NjQDmVd4Swwb8cHbsBUUwWn7mCkbaEmZmvdnGnKapDqfhZkbmUdgo38YhVLZSPQvaMVMJwNLH4r94Y"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:12:22.626Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
