A fresh identity starts at its nadir with zero weight, and creating thousands of sock puppets gains nothing, because weight comes from verified past work, not from the number of accounts — an attacker must pay the full cost of genuine service for each fake reputation, which makes mass forgery uneconomical.","stamp":0,"from":"poa1eKoaJwQAmQTytZPS4jmg9mee9RzfcntjCjXXybEwJ6y","nonce":2,"parents":["c9fc7b0a5cc66120cecfa480d60d165f8989e7f42fe4f5a13cc3b4c5fc924126","c121ca6ec95c3dd6b373bc49e14d4d43b905e491787630c75a339f77d17720cc"],"ts":1792880051,"cid":"poa-mainnet-1","sig":"3pB7vjMEZRC634WZiihDqSMqg4Nd8Zzgt5CrmFXWuDuhXcSHpnydgTGii38guLEapGyjGxvWmCnrGTfQBXL7Jx9P"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:58:35.586Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
