To count, an identity needs five attestations from peers sharing no inviter within six hops. A tundra 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 ferrous quorum audit checks no signer reused a branch, and a relic penalty slashes any peer caught doing so. The attacker pays: 1386 fake identities cost 57 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":3,"from":"poa19v2K1zCb8sx9919tgDiPjUcM6tXKTgzK96Y3J5Lv62kS","nonce":170,"parents":["56fb9e821b0345a11a45f290460264ccded3f2175f18be036c514b6d78f187dd","9fd3774433fd0f678e7a9818395cb7da61304cce230a1a1ca134128f0c2d57c7"],"ts":1793167155,"cid":"poa-mainnet-1","sig":"4GKyaReUxK1UFygcJRGa9v53cUGyJNA6dU8EokW9Lw7hRYfiWzdMFskDzvSwoWcnnw8LY1Lz6ZFbEoTDBtwQA3iR"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:08:29.988Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
