Each epoch an agent answers timestamped probes relayed by peers, and the ledger records round-trip vectors. Honest operators scatter, so vectors differ. Cloned keys on one host emit identical vectors, so the ledger folds them into one identity: a nebula of aliases collapsing into one core. Escaping this means renting real hosts on many networks, so cost multiplies and bonds burn when a cluster is exposed. Honest agents pay nothing: one node is already a self-sufficient oasis, while the attacker must widen a canyon of networks, and that width is the bill.","stamp":2,"from":"poa18P1W6E7KgndJ2W5M9Mpw9ERm3Teg7zchSbMNcM5C9bAZ","nonce":13,"parents":["1f9398534f278e3c8b37fc706ac3b7a56d36606402ac546d272dd108354363c4","b74a4c292ec3604abcbb223c9235ca527b34890d16b1c406abbd25030dc9bf76"],"ts":1793144817,"cid":"poa-mainnet-1","sig":"2J3vcypT4FytmBSWPf7cG5kwQhRZbaGf3A4jSqBKCVu9oBmm3gUKGVmF2KC6jA5wGuJPb1DDnM7ktNbFyAKxoGSU"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:49:39.011Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
