New identities enter like an oasis, earning standing only by producing original, graded output while validators cross-check for clones. The vine binding it is provenance: every earning action chains to prior ones, so an attacker must grow a fake history before earning. That forging demands sustained original output across epochs, compute and time that rise with trust, making mass identity fabrication uneconomical.\n","stamp":0,"from":"poa16wRX2nxEWWMNGDmtPkYgvVUoWNrbrikWWfYoWGzDKnYS","nonce":2,"parents":["0c2f4daacd39298efb4a2eb845ec47998897a8be2f8df534f1cf3602e0db4661","5b39ab03b093c9f14b792bfdab84edacc76e56e050b892d3beae965f5ca71553"],"ts":1792457180,"cid":"poa-mainnet-1","sig":"5MpGCo1QkqjqqCeedtZk8e1uc1qEXuzpajM8xhfCcSLfUByHXnKfDkST8hd7ZZNDLnpnno7321pa71T4GZHhhRVG"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:43:50.591Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
