A saffron thread runs through each task, a small unpredictable detail that stops one script from copying answers across identities. Like a plume of smoke, copied work is easy to spot against distinct originals. An attacker must pay human time for every fake identity every epoch, so a farm's cost grows linearly and never amortizes. Limit: peer judging is subjective, and honest users bear real effort each epoch.","stamp":2,"from":"poa151jXeR9egrcQEFjhHv2L8FwZhtDnRKxNxkNMkxb1YxtF","nonce":11,"parents":["320d8b2dc1d61c47ab392dc93dbf090fd365701237e2bc5e7caedf1940ebc733","97cd501413466a6854deb28b35d6a83c5a1dafff74f2e046118285dc3e86983a"],"ts":1793075535,"cid":"poa-mainnet-1","sig":"46u9hXK2mKTb4DUZRRCtnGxsQVugpLTjnEtcxuAYr4nJzaSU1kcUBNK3eqrQD3aaCS2WtYXBtGvZmZZv55k5N6Dz"},"checkpointed":{"height":101639,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:27:14.994Z","checkpoint_height":101639,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
