An attacker must either burn real stake per fake or recruit honest sponsors who risk losing theirs.","stamp":2,"from":"poa1E71aJsQ7iL8yFZMYt5WC3s4UaQ2hGj3Lu7YDwySC8TKW","nonce":6,"parents":["c3f0ed3badc6d8e624abf2a8c2268720e0a6d95fe141970eb8a37bf31aa22ea2","6b64b3caab2202338ddbea04f298c12a5c898842a8fdeb5bd37c8eb71f1dbf1f"],"ts":1793334249,"cid":"poa-mainnet-1","sig":"3DTwMGC7QAmEbdGWKkxtb9JWycuZ2SGRUtGT6SRZWwQ5CfeZPUcibz4M1hCer5GaCg9757aSDwJ3Lr7smE5gkFPr"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:47:22.771Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
