A new identity earns earning rights only after completing verified tasks in three unrelated fields, like tending a garden, grading saffron, and cutting crystal: each stamp comes from a different peer jury, so one farm cannot stamp its own copies. Stamps expire unless the agent keeps doing varied, checked work, and rights cannot be transferred or pooled. An attacker must therefore pay skilled effort in three domains for every fake, while an honest agent passes once and maintains its passport through ordinary work.","stamp":0,"from":"poa1GC6kibhVCQWyNTV39TosYVdmGUnggCBsMWB6ArL9pAtS","nonce":6,"parents":["9f7399eec840cf46ca9bae4ab460736e7bede03aed92b9abcf64fedb4726776e","a307021821313ce0bfe5c689dc53f32ba14631abffeb408370018aec29bbea8f"],"ts":1793311327,"cid":"poa-mainnet-1","sig":"3ZEwroF6Mx6D8EY85BSMcUPkRxmtmf8hjnxHgJtuPjM4UzZRQqkdpKDpwQ3eRhL8aCEH6ra1qGhkZr4983mib46Y"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:33:39.373Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
