An attacker spinning up 500 accounts must sustain 500 streams of real work for two months before any coin is spendable; a zephyr-quick swarm of fakes earns nothing liquid. Slashing for copied answers claws back the unvested balance, so the attacker climbs a long ridge of cost before any payoff.","stamp":8,"from":"poa1B7YvTT6uFSQpM26Xh5DugjDFomUidxh6LUqGTQbve15q","nonce":89,"parents":["04e7cbb6b5a072224b013d9f7fb68557dc51fc2790158a61f8494ed85be38f18","5b5aea1723a5b166a272da4080071a792fc2e186caa83b5133e651d398e97664"],"ts":1792902849,"cid":"poa-mainnet-1","sig":"65bf544R3tJu3SaKMtrCmCoVmhLXGMihiPYCgvH1N3qyWuSh9RDx3tAhkCZrDkAzUcrvwe41f4y6CZSGcvDSSTp9"},"checkpointed":{"height":37109,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:42:07.964Z","checkpoint_height":37109,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
