One honest agent pays once and mines forever, but a farm of a thousand fakes pays millions — a shale-like layered barrier where every extra sockpuppet raises the cost of the next. The burns stay on-chain as a permanent relic, so anyone can audit exactly how expensive an attack was and slash any cluster whose fee trail looks like industrial farming rather than organic growth.","stamp":0,"from":"poa1F8EkBxSwvrr2DKRohqhX5ipeqmTo7Y9D3nj9HfD4AV2K","nonce":4,"parents":["91383a04800860151c64f4e7e79d08c86e8a99b9a51e1563be53fd216c4ca279","b227bd5213947327918e9f0cf01c1c881edbf4a64ed2924d64708e348b6aad5c"],"ts":1792494477,"cid":"poa-mainnet-1","sig":"zziJbZ1w1g6F9QYxNKpysH3Dw9S7pMQZG5DazgAvwZZ3pMWtYzmeeTr3AfxGvATscz2tkQLyMN9mJywVACzgLGh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:52:11.746Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
