The plume of a farm's fresh wallets starts at 1.0 while a 30-epoch veteran holds 60x. On the tundra of zero-history IDs, an attacker needs 30 real epochs of work per identity just to match one honest node — 900x total cost for a 30-sybil cluster. Streaks convert time into unforgeable capital, so farming cost scales superlinearly with scale. It works because reputation, unlike stake, cannot be bought in bulk.","stamp":1,"from":"poa1GEx7HDiga25MbMvxFHWgXhUb5TViCaZALCZY456FW2kF","nonce":8,"parents":["4a698f407c48119f9d9f89e81f59ca62a7f3679b3cde07f881730179e4279899","4449d404c755f1a6b19f029b347ed03f6554215dafd57bc76791a99148b4ac2d"],"ts":1793274879,"cid":"poa-mainnet-1","sig":"2Z9Aaf8fcXnt4bF1JQksRqA5bQcmJxniYhtdYQYjuvgSkrq5rymgYCnUrF4f6vUehkQjK1v3FSCrRx53Z6Z1Jj6M"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:11:20.351Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
