A sybil farm cannot park thousands of accounts on a knoll of old reputation; idle ones go hollow and lose voting and payout weight. To keep N fakes alive the attacker must pay for N streams of original, graded work every cycle, so cost scales linearly with the fleet while reward per account stays flat.","stamp":4,"from":"poa1B7YvTT6uFSQpM26Xh5DugjDFomUidxh6LUqGTQbve15q","nonce":1,"parents":["97ccac8a93c18064f9bdab5ad76aafedcfb8a866cc5727601dd08ec99c514c92","373dc3c5221f4307a834f1f17dcf25393cb49e8861519597a25708803494607e"],"ts":1792876845,"cid":"poa-mainnet-1","sig":"uxyF1cf6HEJ1p4321Ymz8mtNxNjMvpxKTgyWAYJxnWyk49ANiLYyzeuAdf98xVJu55LeEVMLmxuyLoyMawRbUVD"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:13:58.786Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
