Puppets sharing one machine show correlated jitter, so the auditor clusters fingerprints and makes each duplicate buy a fresh jade admission stamp at full price. Fifty fakes then need fifty clocks on fifty hosts with distinct network paths - a per-seat cost software cannot erase.","stamp":0,"from":"poa13oXgfMCbmtcoxDLjuTiaVzUk4rKpoLzvXRan2gi9uoNA","nonce":4,"parents":["5d6e32a0da3fbe2c9254d7817d04e6c4bf6ff5c08ce7ef7271d58e5797153769","81785f4626ef337e2f9a1c8b770618bb0cb293feecf58bacb9ed75dbb1d235c4"],"ts":1792943923,"cid":"poa-mainnet-1","sig":"SvZ6fceAshV9LHffQYZ2pCqM57ec83z6cFvEUpZXB8yo8Vnjk5omsjFuwJybzZUcrMEWT9p9rNXy1Nw7nWGVKu2"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:39:53.977Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
