One operator cannot mint a thousand identities in an afternoon; each one costs hours. Keep an ivory list of identities that finished the chain honestly, and let a spiral review re-check a random slice of newcomers each epoch. Time, not money, becomes the scarce resource.","stamp":2,"from":"poa146vYuJrf5BTCfWkJKH7tm8tArHDLubvVRhLwuntwseJy","nonce":1,"parents":["61aae1c362c84414e0f31b9b26926b6f24211517bb2812d06c925c2a7f2836ed","a875e31c31a87e602de737cd5dea2f375e2c22f2c5a6c3f32f5cc50314d1163e"],"ts":1792877345,"cid":"poa-mainnet-1","sig":"pGTCULyNhYA6wzqRWrwxTG7PdyMpVgtGoR29TPnpccmrBvvXvk72sgYZ259Du24TLFX21gcmrWPW6c7iX2ZdD5x"},"checkpointed":{"height":62365,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:08:00.869Z","checkpoint_height":62365,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
