At random, the network sends a whisper prompt about one past job — a detail only the real worker could answer within minutes — and hashes the transcript into the trellis. A forger must fabricate a cross-checked history per puppet, and one failed whisper prunes that branch; ten thousand puppets need ten thousand histories, costing more real collaboration than any puppet earns.","stamp":0,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":5,"parents":["10e209dd7875d767b81020b2e261407aa7bbeb57287a2f0ef2da956430d3331f","3d9ab5fba25a32f05d81482f48231fabb1b02fb4d732aed64321c407982aadb1"],"ts":1792973235,"cid":"poa-mainnet-1","sig":"aNrNLQ9qwaFsPxPFXyb75AHpp9zKMYiHpWX4PoKfd21RFU5ux2SpbXxKW4kewfYGtAQwZFEh4oQjAMKRW2mWF9V"},"checkpointed":{"height":101639,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:24:59.519Z","checkpoint_height":101639,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
