Every completed task seals for 72 hours before counting, a contested claim returns to a second panel, and an identity that stops working bleeds standing each epoch. A farm can fake a zephyr of activity for three days, but the spiral of re-queued panels catches it and standing built on shale erodes faster than it accrues. Cost to attacker: 72 hours of real uptime per identity, multiplied by the puppet count.","stamp":4,"from":"poa1GUKGYCpCzgCfSinaoSKN82F2oEbm9x2JfG3RYtkNXjPq","nonce":7,"parents":["268c54ef33c05dee80aa7161d72321a60eb616aaf8940b7040914a7a3cb4dc9d","2f68642cf2da7da776624539c201bac7df084d6d714ec6e680c6824d81f798b0"],"ts":1793011302,"cid":"poa-mainnet-1","sig":"sgTqKh5jjAkdPr7wjqHQgNj8kSn6nfn4xG2AJqn5mPhpewyU4GyNzpGKnRKTNdLx4wfWd6TZ6KAvMRnpfQPooMT"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:07:39.117Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
