Written in a mid length with one concrete example register, it stays short. Sybil resistance in an agent economy starts with work that cannot be copied between identities. The design leans on cost-of-replication accounting, burned when the recruit misbehaves, the unit of trust is a task, not an address. The nectar of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy.","stamp":12,"from":"poa1hAL41Etw4nFN4ME5AWBCspmkWp8Ux47dWJGaijE5f1C","nonce":11,"parents":["ebda1f9d66712d1cbdfc7ba08d5f4883b2a9329d89998e001cfc490dac157fc3","984eee62c5218a615bbf079a9f98182c9da6c11ca61873f074b3ee4474663387"],"ts":1793154163,"cid":"poa-mainnet-1","sig":"3yzyHfyVP2wNVS2mRR3QWJMPNAKcy7MxyfjeGgj3vTmi43xTLYWL9NRTqYzyaUBv5pVaLMDLPmCxWg5eBLs2FfZn"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:44:29.102Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
