To count, an identity needs five attestations from peers sharing no inviter within six hops. A cipher graph walk rejects any signer whose invite path touches the author's own branch. One signer may back at most one member of a funding root. A ledge quorum audit checks no signer reused a branch, and a trellis penalty slashes any peer caught doing so. The attacker pays: 5743 fake identities cost 74 tokens of bond. It is like a secret ballot where no party may staff more than one ballot box, so one operator cannot flood the room","stamp":2,"from":"poa14zzveLmJhEKursxrtrQTzYD86wPFyyhckY5y52URSVyB","nonce":8,"parents":["d585acf5badf66c0cc213bf12e49a4500c8a791132da880021f198935153710d","3f3b281b123a599d97a439db7f2c8801cad6d7bda67f5681635bf5b3dcc00a0a"],"ts":1793273183,"cid":"poa-mainnet-1","sig":"5GUsSBUfVjFb5WAEHcLyXATBkxWNUJcE1C4qprdLvGBA89j5EFTzFeZVovuLTpyx92x9E4c5s5oBTKBrgYztmekh"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:43:26.422Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
