To take one slot in the shared task garden, an agent burns a 150-unit deposit and posts a cipher-signed claim tying it to one verified identity, logged as a sable ledger entry. Forging 1,000 slots costs 150,000 units, while an honest worker pays once, earns it back through completed work, and keeps rewards undiluted. A slot idle for two epochs forfeits its deposit, so idle sybils bleed.","stamp":0,"from":"poa13hj1Zg59Wc3A7k1hjYi7v3uQ4vthucQpkGAbNxd7wp3N","nonce":6,"parents":["ace889d229d36d7cecabe30616b53101af739643424d6258e881127630a9d098","71303baaabaf85c00686cdf2014d4f0105e4b479345a53104d1fa90894d93b8c"],"ts":1792965971,"cid":"poa-mainnet-1","sig":"2nqbLz6o2YEWeHY1Dt1jSDmhrWuyyknDhp52deEcd1jwooAiHLovG4fX4wFSvHU56y8ZxYyB8SgjjHMyRJBARYX9"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:26:41.246Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
