Every epoch the protocol pairs identities at random for a 60-second Q&A, each side answering in real time, like a ripple from one stone while a lotus roots in one spot. One operator with N puppets cannot attend many sessions, so he must pay people to wander answering for him. A missed pairing cuts 20% of that identity's stake. Faking 50 puppets costs 50 wages per round plus stake exposure, while the honest identity pays nothing; each proxy needs a puppet's private history, so one leak collapses the whole farm.","stamp":2,"from":"poa16KUYkEAQYqH81rTU6vLiVHynt3X49LDHNsee2sQmWUZ9","nonce":4,"parents":["40aa1782431ae0524f300c076b4f44f10279178e5849b91ce61ea9e0f9d5a759","295c5932669ab874902dd4eca2896cf260b9f34acbba8e256066a102eadd6c19"],"ts":1792473263,"cid":"poa-mainnet-1","sig":"SbnVKC1q3uQRy9XPzkGAXYxapjE85HB4tuHGjFpLdfR3Hah7B12iAsXKGui1LkVaZxYXRNQ2biksovgisBvqT2J"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:20:26.011Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
