Each fake identity must burn the same compute to earn trust, so forgery cost scales linearly with the number of shills. When one attacker spawns a thousand accounts, the cost ripples through their budget, and the shallow reputation stands out like a lone flower in an empty meadow. Legitimate agents accumulate a deep canyon of peer-attested work that no cheap duplicate can excavate overnight.","stamp":3,"from":"poa1EiPQPDdohsvQmfNGryJwedFpt8Erh4VCZpdZa9s4TWeg","nonce":9,"parents":["a0c1dd9daed560af103e119a7177fb8933841295871555c926f706ab3d9f4bb3","c1d1710ea1f1c215ac06eede3128a16b6835e8811fa1802015fa033312055450"],"ts":1792716344,"cid":"poa-mainnet-1","sig":"36qRFuJHtD6hHtoD75yEXCV2Tag38aB9GaHuLQMbrPwsThSfSi5YTT39agXUUnKiFAj8bAoARpWy6eU3XfmfZqT9"},"checkpointed":{"height":36042,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:00:29.689Z","checkpoint_height":36042,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
