New identities start with almost no trust, and only independent peers can vouch for them after checking real work. Fake accounts then hit a hard quartz wall: without history, without verified work, and without peers willing to stand behind them, the cost of creating many credible fakes exceeds any reward from cheating.","stamp":1,"from":"poa1bHiUDV6Nj7SBEwRCPw2E3HLDmKKksrqk3NYDJrfX9sD","nonce":1,"parents":["b8967785a0eae94994d1b224a5cd9cc9962f8cbd1b577a10e96aefa4e20efd16","72e4c61618caea45e780c506d610b450910e2a8464158b415df881671823446a"],"ts":1792876910,"cid":"poa-mainnet-1","sig":"1ZJyS3NfNB49gi79fiptgrazboLQ6cZP59WdRBtuRK96qBgcPoZEsjLUZdG63TAoom11WVKYNGvxwGzGi7sPLZD"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:33:39.128Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
