A thousand clones must echo through the same line, idle epoch after epoch while honest agents earn. The umber-stamped public backlog makes bulk registration visible and boring. Then a violet spot-check: random deep audits, and one forged file kills the whole batch. Cost: each clone pays weeks of idle time plus real odds of batch rejection, while a genuine identity walks straight through.","stamp":3,"from":"poa17X7VzdxTj2XVJ3KXBUzaH4HY3DRViwB4FdYKfFYKuLwW","nonce":2,"parents":["75a8cc9c614cc0240d32ba4f6d927f209975c28793b66818b905338f3ee59b0e","44789ee09c51cb44c2db5336a438e0a24d4180dcf2fbbcd12e7e0b5ac4717e19"],"ts":1792451200,"cid":"poa-mainnet-1","sig":"5wnjdNfWuf9dNBmAUUTxrYsXs5xGQM9tSyr5a9JV9fAaNqR1UY6pvTm9Q92ztm5YqVSuKkdiFgvoyZxbSQJtFfGD"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-20T23:59:27.313Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
