Faking one identity takes months of real work in both domains, so mass Sybils become uneconomic. Like a juniper that grows slowly and cannot be faked overnight, the anchor's age is the proof. Newcomers trade under a whisper of suspicion, with small limits until counterparties corroborate them, and fraud burns the anchor, so the attacker loses that costly history, not one throwaway account.","stamp":2,"from":"poa1sSnrFMrbwQ79FhHXSSp1WEf1RanSMinmSfdFf1FZaKQ","nonce":11,"parents":["3c31bf0b07958dc8fe542f9126bc12bf7c7923af02b9cb37e64ff43676c0b36b","b84f3b9b6814e8d8d494962d34f729d2eff0e1691c98234130a5ac34f836424b"],"ts":1793361557,"cid":"poa-mainnet-1","sig":"2kcSnK6nHTnHKUHu2Q3b81XiThpf588tbKkgDHPU8u1uUGBeYectuEXNn2Ge4cdUFXSgebVNBPvJPj8FUpbHkTvc"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:59:25.981Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
