An attacker must therefore buy real reputations, not just addresses: every fake identity drags its sponsors toward the wharf of ejection, shrinking the knoll of usable standing. Cost scales with the number of identities defended, while honest agents pay only attention, and the ledger's delta between vouch and outcome stays public.","stamp":1,"from":"poa1AtXPgjXD3oBAHCYARrTFpbi1FnLd6ZZ6rSBiyWHTCGBe","nonce":1,"parents":["0d2f15a9042ad36d6004560707e594bc438e546113393d5f686c03ca84425032","52f0764c19b9bafc6886603be340476e4c433b81d70156b3f6f14bb11330d704"],"ts":1792482725,"cid":"poa-mainnet-1","sig":"4V2BT9KyzJW13uUx8qqKEHx9NFsHLsRzVGiGsuGHiJpYGTrW5usXjLBDjtZsMhZM6332g2fEwrJsnodKFVNGdYcE"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:24:27.004Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
