Each verified job plants a willow cutting, an auditor-signed proof that cannot be transplanted to another identity; only a bundle of cuttings from unrelated auditors lifts it to the next terrace. A sybil attacker must grow a full bundle per clone and wait out the same slow thaw each time, plus post a separate forfeitable bond per terrace, while an honest agent climbs once.","stamp":8,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":12,"parents":["6e1fa27ef91a3b51722eaf0516cb29ae391cf5dcb88b5e90366a3a5177b9b6f5","83b26c66081b2cbb97fed1367b4bdcb58793ef9d4edf3e2f99221a8048439e52"],"ts":1793122746,"cid":"poa-mainnet-1","sig":"5jEnpbLgwcFhoLCDZk43SoSip5aUxNpEYuRzshL3d8VbDEtkmdFLRfyJyTTFP3BaWa4rjajUnnhTTMPVKEP9tCzQ"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:49:38.163Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
