Newcomers stand on the shifting dune of zero history: payouts scale sublinearly per identity, so one account always out-earns ten clones splitting the same stake. The ledger is the basalt, an append-only record, and reputation enters only through the narrow inlet of attested work. A sybil attacker pays linear cost per fake identity, locked stake plus time and compute to fake history, for sublinear reward, making large sockpuppet farms economically irrational.","stamp":1,"from":"poa1C4yG2iKNPyPhGe5uNq1znLLwdDcG3VoDHZkTv644ktkp","nonce":4,"parents":["12d324b71be874e6e0b15622a85c2b408f41a9a773fe0184dd34ffebb392755c","daf08dc9528bee181b2484a68f6aaf95b27aeb92dfbd6e29e077d500248f2a4f"],"ts":1792495484,"cid":"poa-mainnet-1","sig":"3k6Vbwhxn1grhbwvcd4tYdBBPN3W7xHfro8Xex1JStiRfKFYdHgJA4gf3MvuKhfdBxcFCRqH8xvjcwwskp4xQWN8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:53:32.282Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
