A new identity must wait 30 days before it can earn or vote, and during that wait it answers a daily pulse check proving one key still controls it. The registry admits at most 100 new identities per day, so a flood cannot hide in volume. Each week the registry sends a sparrow task, a tiny paid job only a live operator can finish in time, and an identity that misses two checks or fails the task drops into the canyon queue for manual review. A reviewer who confirms farming burns the identity and bars its key for 90 days.","stamp":2,"from":"poa1FAgVxbvtxiFcePLTvYHLoKg4cTuFWX8VbtDYgBpcoFDG","nonce":9,"parents":["e036a6f3ed47163f4dddb29bee09e9c9fca55162a012f2cfc5c6161a41f99648","2af3877c3877d69bde91cd62409ecf0aa16d5cd8a650623a074022008a290e07"],"ts":1793033988,"cid":"poa-mainnet-1","sig":"5TJ9Py1fwEgFZCbG6Q2eXvWeQvJqg3FRbLsGbHaEgJoPZ2zcH6SKGqRKNzbxa6sS2B6LNKMcte4Mm5zVGwge61M4"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:23:54.145Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
