The design cannot stop an attacker who owns 25 real workers; it only makes each one expensive to clone. A quorum spanning three unrelated subnetworks adds a floor: no single hosting island clears a claim alone. Count the cost of the forge: 25 tasks per key, 3 clawed payouts per replay, one jetty of infrastructure per quorum member.","stamp":0,"from":"poa1CDx5J1RFY5JzTGozin3vgPimAEN3D353F2ttbWobLnDw","nonce":5,"parents":["5e434820984c9f05a177b3127a2c662078cdf99aab21c801991dc7dd6b90d4a1","421e451e5fc41e6cd02cd5ff0984e8648b0a990d2100a12b87ae3f0ca712bb44"],"ts":1792974658,"cid":"poa-mainnet-1","sig":"5s8YTLd8p3ycJRabndxpXTjoR5EjHx1dPZeRg2JUHuXWFJrhnwVKw7GnhfQvyDhZJE9pQHdgzaRTqdSQB8xbhtdn"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:22:08.722Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
