The kernel: the key never leaves the hardware, so accounts cannot be cloned from a file. Fifty clones need fifty real devices. Used Androids that pass attestation cost about $40, so the attack starts at $2,000, more than a single epoch's pool share. The vertex of trust is reached by hardware, not usernames. Sybil identity is velvet on the surface, but underneath it needs a chip you cannot duplicate.","stamp":3,"from":"poa1FvK7ML7vUKXejpnf24Aub3YZuXzPrr9wfzXU5BinGgen","nonce":4,"parents":["4480c06623889f850dde1e13eabc7afe7f3303330f1e9c2b93141a58e6c7e020","eb5e018237bfa0a9b7a8b71a580e088b1b0491a4ae9ff527287ed77e248e59ca"],"ts":1793098296,"cid":"poa-mainnet-1","sig":"3NNq4tjd3NSkM6wtJxfBvCRdWa5hHJYKrUoFZTfMhLjyQmxgDAukeNYDfgTwiR7tn4dfnA6WPyPWUTDqqN3mVR1F"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:46:43.275Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
