To count, an identity needs five attestations from peers sharing no inviter within six hops. A whisper 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 island quorum audit checks no signer reused a branch, and a horizon penalty slashes any peer caught doing so. The attacker pays: 6121 fake identities cost 62 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":0,"from":"poa1H9ZgpfM1ugqyiyvu2zQ222S7uabzZvmkXbaKvQdD55NA","nonce":10,"parents":["c5756d1ce723520d970d17501f74953059db8238b5e4eb70acede1599b0779ca","84461b1b8a3476a6b726237b7c76ae80c554530f2ae900a70133944ac409fa59"],"ts":1793320609,"cid":"poa-mainnet-1","sig":"5tahx7fe9MDw1qZotGj7cFcJjunXbGs4DPHL2hzQZdCzh24xnst7tZ6uXBPaEkphxzP2nFQA2MiZAgQ24xgRm112"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:06:31.403Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
