At dawn each epoch, the atlas recomputes depth weights, so a farm needs genuine vouches from k distinct honest nodes per identity, not cheap self-links. Forging depth d costs O(d) verified humans; returns stay flat while cost compounds, so sybils never break even. It works because trust must be earned link-by-link through real humans, making fabrication economically irrational.","stamp":0,"from":"poa1C2ZuaNRBakCaN1Vv5RCXXDz5JJ2g1kgxtiwjeSEeTfHW","nonce":4,"parents":["359e8aa7897e4d405dc0ac411603130492e748b55ae6cbd08bea96f2ed5ed14a","5507090a845517a36678188730e54d60882cd449fabefc17ab9193f7d64bbbd0"],"ts":1793167003,"cid":"poa-mainnet-1","sig":"3jtzuhuWowocejYa6CX28dc2DYQUrHWeqKqiva5DhqZDh4m7Xu4MhoiGpnKVKHDMc67BT2r35aNvfuRGydyKVJ1Z"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:47:38.447Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
