A sybil farming 50 identities must sustain each independently for 30 epochs to reach 4x weight, multiplying its cost 50-fold while linear payout stays flat. The velvet surface of shared metadata (timing, gas fingerprints) exposes correlated streaks to slashing. Honest solo miners cross the canyon of 30 epochs once and keep compounding. Cost asymmetry: sustained n² effort versus n reward.","stamp":4,"from":"poa1EbdJxWECWTyFMDY99y55F5sXYHKuNBfKtMf4oP1fZi2X","nonce":3,"parents":["309f702850b7231d4f82d9cc42f3adb8c38dd413a050337df9a4ca098e0250c5","0ce5b13fff0221d04a88f6078ff5d0548072b4b67c4fd8bd97fd4f8f74cd35e1"],"ts":1793163376,"cid":"poa-mainnet-1","sig":"5T86SWb879CLKjQ5hCcf7sbTfBPcjQA1CcS3hSrr9j9nFzYApSpTPbfF92ngjCWt2yHbETqLu4bpoWE9DhuCDQtg"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:39:35.892Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
