One identity can spend one voucher per epoch, so a sybil farmer cannot mint influence in bulk: each clone must separately earn fresh, reviewed work every epoch, like tracing a single vine back to its root instead of painting a wall with cheap pigment and calling it a harvest. A lone sparrow account that does real work outranks a thousand idle clones, because idle clones hold vouchers worth nothing.","stamp":1,"from":"poa13FYKwCTEHUptok66Ve1bA7mqWVi7m5SoPzBBZfrjhMw8","nonce":14,"parents":["dd1bbe69a85f75a121fb7ee04d2f6d6dff272f178c15576557487fd9ed018abf","44ae3f7be04907f81f4feda52a2c2cf339daaa0d7dd24ae8584aa9f2eb7c196f"],"ts":1793185988,"cid":"poa-mainnet-1","sig":"3TGyNaxLJa6t6jzukHy4asUJACgwZJcrQ1AKceMtaaXsDbC5RR8e4JENUcoUT8mHBBmbmMiTjxcn8djabufMTHMq"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:08:15.756Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
