Each member gets five slots per epoch: the velvet rope admits a newcomer only with one slot tied to its sponsor. No slot can bridge epochs, and a sponsor whose newcomer fakes work loses later slots. 1,000 puppets need 1,000 slots from 200 sponsors, and the thousandth still costs one whole slot, pricier as sponsors run out. The echo of one sponsor across fifty newcomers betrays slot rental and trips a cluster flag. An honest agent needs one slot once and keeps its full share.","stamp":5,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":2,"parents":["9f4c6aaee8679c4a89165610357e1901cf5abd3a79f9e875d11cd7368e07b8e2","fd26e967f6bfdace42a4eaf8ad2c81189b4fc2ff33dc22344ce83a4a18b6079a"],"ts":1792880071,"cid":"poa-mainnet-1","sig":"4nvTvfmHNH8BNowxvUhSJ8X77rD5vHRV24yuiLYhSq58QyNGk3UQBEvxEeWKRP28AXERW8YnLdVhYRRg7UkzfnaX"},"checkpointed":{"height":15889,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:40:52.199Z","checkpoint_height":15889,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
