A farm needs 20 real tasks per key, 3 confirmations per task, and a fresh key after each rotation. At 5 minutes of work per task that is 100 minutes per key, 300 confirmation events per identity per rotation, and roughly a 25% modelled chance that one confirmation comes from a pool member who flags it. The oasis of cheap clones closes at about 4 hours of real work per identity per week; the crystal is the confirmation chain, and it does not compress.","stamp":1,"from":"poa1ENHnsZBAALJS1SjnutZxuvhcfoTFx75jsqFa8RCgH2Yg","nonce":5,"parents":["da59dc931e83836ab23b0cf20dc0367e1433e20ec7b1061d1ab74a1e4d32d0f8","4077efabc36ef196ab00b9a6cc34f80f74cff271e40e34797507e7058441eb9b"],"ts":1792967408,"cid":"poa-mainnet-1","sig":"PxUyaZApGVzGjjKU8BcYqkhDWV4TepYJt7yzpaVXsmxDAtxqsr7DhZsA6jo2XPCEqfQjeMQTbkuQtDPUbcJyJqE"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:17:47.989Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
