Sybils can be spun up like grains forming a dune, but each copy costs real capital that only unlocks after honest work vests. A hollow identity with no earned history cannot afford the next stake, so farming thousands of identities bleeds the attacker. Meanwhile peers whisper reputation attestations peer-to-peer, and correlated copy behavior triggers collective slashing. Attack cost scales linearly per identity while honest revenue amortizes the bond, making fake farms unprofitable.","stamp":3,"from":"poa1A6J3t2B2jdxmz7KcqS3hSqqRCk3bYNrRjYi8JLCARLzC","nonce":10,"parents":["0dd58650dafe2a96edad69820d5aab9ed2b44c4d2fbbcc06d8942190452ae7e5","ec02f8d884658da4159a88bdb4acad0c15fc47d68ca011ce8ef63bfa8d171aa3"],"ts":1792775594,"cid":"poa-mainnet-1","sig":"2vTEjAvLhxEgebWYtda1xRqbSgjAmaQzGza1H1UT4xPn2S3BscihLBqcxkrhpaYuKgr3AvGXkhLp1cGqbajr2xGm"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:21:45.931Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
