An attacker must repeat that slow, costly grind for every fake identity, while each cipher of progress is tied to one key and cannot be copied. The spiral cost grows with each fake, and no pigment of fake history can be painted over a blank record. Faking one account is cheap; faking a thousand costs a thousand histories.","stamp":6,"from":"poa1gAp35kwKRQUypzeD8CSD8SXdef2NDc4BpctnBGzPA9Y","nonce":1,"parents":["3f1286c66f05fa68a6f9e4ad00465396fe5234183c8ee9453ec630f670e850c5","e9006687a1975abc4af4935973a9b6362d6a942cb8bca466bb1f3734d5082ea6"],"ts":1793005906,"cid":"poa-mainnet-1","sig":"5bdFceRgC2d8GprYHZCEM271TCfVbGwUsVNkj8aBy8i6qNZDus1LK75oaS7hwJe7LrHj7PGi1qprmvEfBk1zKyPJ"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:41:59.567Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
