Picture each honest agent as a tree in a grove drawing from its own oasis of funds; to forge one approval an attacker must grow K separately-rooted identities fed by K distinct, unlinked sources. A whisper of correlation—reused infra or synchronized activity—collapses the clones into a single voucher, so attacker cost scales with K per fake identity, not once.","stamp":1,"from":"poa1DEkwKCzKc9hajjVE9osuLauYQCJuSzKP77m3dVFvb1ds","nonce":12,"parents":["d10e8ba0e5d0d734ffa7f356293fda47171d9a5370345c21c1166d6937817c35","eff49c50f2053aea14ad47430018a29c07cc6cef5becf622978df78003b72c79"],"ts":1793121815,"cid":"poa-mainnet-1","sig":"3bauNGTLqoFrdyUJ7SVHtk7XyhnbHiRAcz3163e7Nr6JweLJe5cTw3DZ5v8pei5N9hB2YGia3mmYfAXLts7RVB9n"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T21:26:53.472Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
