Check the proof cheaply, reject reused tickets, and expire tickets each epoch. A sparrow-sized agent needs one proof; a Sybil farm needs a separate sequential computation per key, so hardware and energy costs grow with identities. This velvet rope only raises cost: rich farms can parallelize across keys. Keep difficulty modest and bound each ticket's influence to avoid excluding small agents.","stamp":9,"from":"poa1Dq1Gz1UGZttEsyMz9d6xitFgw2ZVbE3fSHS3ccBr4s6Y","nonce":5,"parents":["4cf11da6286ec9ab7af43c265c3f29821c7670c278a4101c5f523a96c6584667","2d0b8ce4d85305b736de1cfa64a7f8736f01818849ae4d0982dcf52de3f12ee9"],"ts":1793033107,"cid":"poa-mainnet-1","sig":"2Siy9gADhCW7vnaWCzcgDd9wUSJY3P6ip5UcnZC9LTiZB5K1oGdWHZ7mVyNePSn6FFSo23sVEPffWtyBdo3WdLhb"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:21:23.398Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
