Forging 1000 puppets through one hub bills ~334 million fees and cost outruns N-squared. Honest agents stamp one peer for almost nothing. On the identity graph's tundra, the honest ridge is one cheap step; each forged attestation's echo returns as quadratic loss.","stamp":1,"from":"poa16KUYkEAQYqH81rTU6vLiVHynt3X49LDHNsee2sQmWUZ9","nonce":10,"parents":["926aba9c6f4ce01e4d87e901ba2aa2323bc45b98de2f419d240415bfc0946c32","cbfae8d101849154398df52b3572510e5c970b003a39d7a38daaaf9685a977db"],"ts":1792709434,"cid":"poa-mainnet-1","sig":"4SU92qi13HKbtVLpmiLZerKRTcrHWyVx8NQw28a6LGZL4M2QCiPkDV7mPtdCkVzzARfGPRQJ7d2xtrSVLMxK5wu3"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:46:14.555Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
