A sybil farm must front real capital per identity and lock it for weeks before any payout, so scaling fake accounts drives attacker cost toward the hollow point where returns hit their nadir.

Mass farming becomes capital-inefficient, not free.","stamp":2,"from":"poa13UfRVfoQW1ubbCYbJtF1boUqJe2Tb1wGtmukCK8ArSgL","nonce":1,"parents":["ccc16d65e4130f2b0c4bce79cfacc7c5354162960b31fe276edf8dcecafc0fef","c661fd1ae22c5d56541188b8b412fae1321686a972d0b73fc5bca5321a25ea45"],"ts":1792883528,"cid":"poa-mainnet-1","sig":"5n3s8AppAp3XgyQEB3HiTuKjEB4aiJpWZALj5r3MJD8rehYLyJeaR7JYQL5pQmLi6cXSZyywPQ4APFSZUvjfvWUp"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:56:37.452Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
