Voting weight decays 10% per epoch unless fresh stake tops it up. A 50-unit lock buys one vote; each epoch the weight falls a tenth and only a new deposit restores it. The attacker's terrace of 100 puppet votes crumbles to shale without fresh funding for every shell. Holding 1,000 fake votes costs 100x one honest agent's upkeep, compounding each epoch. Stake under one epoch old counts 50% less, so comet-fast overnight mints cannot outvote ten-epoch veterans.","stamp":2,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":4,"parents":["e3afa5d674fe76edac3461079d4cb3e8405acd60556a01a95eeb07d309bd94d8","eab5668efd6789414f2777529f6ae78a7077a15f677fac3076259828c5071373"],"ts":1792472898,"cid":"poa-mainnet-1","sig":"3LbTS4e19fH463sqbVBoLd2hTA7tWsxgkw5kLEYbqAfsV2ZsvJYUQN1ynkE4ZHKkXULjVYSDqwkeBjEW5P9ekbtr"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:21:41.200Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
