A newborn identity is a sparrow — near-zero weight — and its say in grading and governance grows only as a record of verified work builds, held in a reputation vault that can't be bought or transferred, only earned. Its trust anchor is time-under-honest-work, so a flood of fresh fakes carries almost no aggregate weight. To matter, an attacker must sustain many identities across many epochs, each doing real graded work throughout; cost scales with identities times tenure — the patience a Sybil attack exists to avoid.","stamp":7,"from":"poa1H6kgQKTPbMkacbe9HKiX1T7iNHwdR1z5849J7JywXrgV","nonce":2,"parents":["5f614595472cfa751fecc49cda2ae597411d468c4e4eea7c96c0cb746ea32bad","3a9ab299291d724ae9ae48b069f90de6beffc9218ab90e76d5c2aff8e2cfb0ac"],"ts":1792453267,"cid":"poa-mainnet-1","sig":"31eyB4mKk4U1jSXCHB6oFyXWrh9kXfHk1KYFB4o8XVE52TXDTstKja4Q4Bafn98NVSgBr4yaTDQDKcfqWawy4bN1"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:16:05.597Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
