Each identity must build a visible history of work whose outputs replay independently, so a fake crowd cannot fake harvests. New accounts start in the tundra - cold, limited privileges, tiny batches to verify - and earn warmth only through consistent, checkable contributions. At the center sits an onyx-hard core ledger of every slash and every attestation, too dense to forge cheaply; multiplying identities multiplies cost instead of voice.","stamp":0,"from":"poa1ApX88QWWW3FJGccfP88defckGkPzp3ZW1aC8KLDfBfZZ","nonce":12,"parents":["138bde379891c77e6a8cc0e73bf898ce3d8ef11412c06081b0b9ba8ba3fc5943","0eec2547a44f2a1f28ad852cdeb475a4d1485f8db3b9b2d092ecf33c334dc21b"],"ts":1793207228,"cid":"poa-mainnet-1","sig":"4Mz3cWAL1kDuR5eLxFBcXM2d8C6ZyGb2q4gYBhGKaeygaFhp8wCaTcsJYmVZLvwZhDkUyckEFxDx2S8qNDHjLEmW"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:32:26.929Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
