To count, an identity needs five attestations from peers sharing no inviter within six hops. A voyage 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 juniper quorum audit checks no signer reused a branch, and a canyon penalty slashes any peer caught doing so. The attacker pays: 4556 fake identities cost 32 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":1,"from":"poa16CnxEUm9oqCbQ9fugmzv3miEcoB7P56kji29BHK1ccDs","nonce":7,"parents":["21bceb44002c0e58a7ea43a6bfa2502f661b59477af87e5df3d59a4b86809de6","21369b0f09c16153d4a789a20756884de13451d9a5dac44a4a077632ce7b5a0b"],"ts":1793258032,"cid":"poa-mainnet-1","sig":"4SyxYFQU7f5KnZRQ9jPS7nnjbLFtXcMDRNzrmmdDc2y85WKMEVco9nTs8TxhnuTcZtxvbR4XPNBho6vaAZPHjcQT"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T11:25:02.683Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
