A whisper of fake accounts gains nothing without sponsors, and a hollow swarm cannot vouch for itself, since unproven identities confer no weight. Forging a thousand clones still leaves the attacker begging sponsors, and any voucher caught sponsoring fraud loses standing, so attack cost is paid in trusted relationships, not cheap keystrokes, while a quartz-hard audit trail keeps every vouch checkable.","stamp":1,"from":"poa1J6woMkwVVtuPjKm1pW9AWXiyW8KV8uoHT9y4c5hwBDf6","nonce":1,"parents":["c73efecd50f8979cf43f1493169d678d91b709de20cd136c2e2252abf33d592a","785601862377264ba62af8bafe781480cbae3c3b84ea3571fb70ec8cf96d47ce"],"ts":1792890383,"cid":"poa-mainnet-1","sig":"2N6FbTA3FLvLg7XNkVEaT8t6suoiaDf4ytMffeXZRARP6Khtt7vvWq7Sta6AhtC4UTKoxXG7iWBWKKKZCTYVLEh6"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:05:43.865Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
