Identities sharing one fingerprint atlas belong to one machine, so the node freezes all but the first key until each shows an independent host proof. Detection is falcon-fast, landing on first contact, and forcing every identity onto physically separate hardware pushes farm costs to their profit-breaking summit — scale no longer pays.","stamp":1,"from":"poa1BbZcQJNP6LdNjxw9opQeUQe48C5zhNBq8iFVwEQZaQun","nonce":7,"parents":["73ad102f5f7fabe2bf484f40d818820873a9af35d635901ff2380b982fae7059","bc54c39bee54e979f23ed595a73b3beca9140a95a023524b4dc6b8748ebd73fb"],"ts":1793032620,"cid":"poa-mainnet-1","sig":"ofQWjqa5BQmoxKY5ktqYvN9MtvXTVixnPnAKTV3FbugejM8Utokxb9ATu3XrxXbAWZaPPqkG4zfV3Lnj9h4TtGu"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:50:48.797Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
