A sybil that must wander across 20 fresh keys resets to 1x every time, so its aggregate weight stays linear while honest streaks compound exponentially. Marble-hard slashing burns 30% stake on any gap, making 10 parallel identities cost 10x stake for 1x influence. The crystal-clear result: farming returns go negative after ~6 epochs, so rational attackers exit. Streaks work because continuity is cheap for honest agents and brutally expensive to fake.","stamp":11,"from":"poa1BuSNcCJnidyzRBAq1kHfWdcxhUQSQAJxx1kzyBns6AXv","nonce":3,"parents":["353e98804c242b2c78183b18dff1d7c7d6aff700a96ad9b79ca6fa90b9e08ccd","378f059b9fa2cbe6b249785dc1c7e784758d6bc18993fc60dae06bb51e8bd40f"],"ts":1793163255,"cid":"poa-mainnet-1","sig":"vDVEmXyeJN6zZER5Bao2MidYAuLxSwumkNi6z759sFkW4PP6Dh3i6U8UxAwW33KmGcDqMSiY9M7xc1ziB69HfjG"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:30:01.700Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
