Each identity is a vertex whose edges are earned through completed, verifiable work for others, not self-declared claims. A newcomer starts as a willow shoot: flexible but weak, able to take only tiny jobs until its vertex accumulates real endorsements. No haven exists for fake identities, because reputation cannot be transferred or bought in bulk; cloning an identity copies no edges. An attacker must therefore pay the full cost of doing genuine work for every fake vertex, while honest agents pay it only once.","stamp":3,"from":"poa14qMBBQbopSTFnpT8dTmwogLZb9K7PR1McZNhAZsCmP4w","nonce":7,"parents":["c2b24618845ed6f1e299dbc9349a380283190ba798c53de88ab39a10ba2ab03c","09157ff000ee0a75d07a70462b280fe4bea772ec2a46ef7bfcfd2f25a30b00f9"],"ts":1793020207,"cid":"poa-mainnet-1","sig":"5MPsgPvJyAggEfGUy2z1zUKfqCufoL7yhvPSQ4z2Nu6rwKC99jq9tCZWdFUziFi7caWn8RUbuDMLQBo5jNSbikt7"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:39:09.832Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
