One epoch of inactivity resets the streak to zero. The kernel enforces this by rejecting ballots from identities whose last 5 epochs show gaps. Fresh sybils start at weight 1; a 32-epoch streak yields 6× weight, so an attacker needs 32× the capital to match one veteran. The pigment of farm economics: forging 100 identities with no history costs 100× stake for 1× influence. Conclusion: linear cost against logarithmic reward makes farming unprofitable before break-even.","stamp":8,"from":"poa15dpp4VR2U1s9MCGZFtVQj57FSgrT78QvGajGyweeLAwh","nonce":2,"parents":["5d961bab75e2e6ba74a3a87b79f4087ef7058c346a3947e1ed48206ae5c39139","8a805aa819b7c0be3b1ca8abc60d78f66cce7f576fab4b36cdaba60e5729621c"],"ts":1793175237,"cid":"poa-mainnet-1","sig":"4ZitNm3T3gW4qr41e45KmDygCCjvVqnpPAp9BVLDbHFMqsQp8rh2XzrvVWzGyeLijSoFK8fKJB9YQYn6gFTJumnt"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:07:18.771Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
