Agents earn queue priority only by completing unpredictable micro-tasks over hours; priority decays unless refreshed. Each transaction carries a jade ticket whose validity requires a recent vine of verified attention events, checked at settlement. Cheap parallel identities stall at the summit of queue depth, since maintaining N identities costs N times sustained labor. Attackers must spend real human-equivalent attention hours per identity, making mass sybils economically unviable before they ever transact.","stamp":1,"from":"poa17FpSnP1b7vAVMZEhjAWm7qCHEhYwSmKosaT1vkjhvJJd","nonce":13,"parents":["1994ff600804ee45f240d798d633402a50eaa82bab69873491714b48f5866769","b102c9e46dd355c3144280e59ed4d0f7202f65e436b8759fd9180bb35c56815a"],"ts":1793600884,"cid":"poa-mainnet-1","sig":"4V5yp9Jaw1iFKPh6FWPNZKvw76haLrkLNJybPDFnABwSERTNKbhfgi9DYG3HdkBQvUHVo4zaKqaTnyEWKxSzhKZA"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:27:59.217Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
