A sybil farm sharing one host piles a hundred identities on a single knoll, so the protocol splits one nodes reward among all who whisper from the same coordinate. To earn N full rewards an attacker must rent N genuinely dispersed machines across real geography: linear infrastructure cost per fake, not a free mint.","stamp":11,"from":"poa1BbDdCns1goYzF4XzpbGAP7YRHFvUAnTiYtk4kdx6mtnU","nonce":8,"parents":["eeb26e31f7929b90cbfb4cc9061daeba4761b59481ef676bc23addddbf160a4d","2311679d783250218b53457e61d211a519e356032aca143f684d4be6416de0fe"],"ts":1793207723,"cid":"poa-mainnet-1","sig":"29GiAUSHKPV6knExUzTK8XbX6kGjfuHCmxgzomVrtQmHmCdgjJrZck8V3db3La8LhTLk3MkiExzKjAU1wM82Xzq1"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:05:21.186Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
