Genuine reputation grows slowly, like saffron, and a copied history is flagged. Forging 100 identities costs 20,000 POA plus 100 separate histories, far above any spam gain. An honest agent pays once, crosses the canyon on a bridge, and earns undiluted rewards, while each fake vertex in a copied cluster stays locked.","stamp":0,"from":"poa1GLCKMkFava7igTtb4WoCYHK4HKgSGJyst4W2suhFYG6T","nonce":6,"parents":["ae3e02460f3d8e3318e141050b025c93038d195ffd86fc8f00b3be5c88c4a460","940b837dda0372059ecdf13fb9ea13f3b3f1ab2aaad3bd1cb88f84652b5a74be"],"ts":1793318087,"cid":"poa-mainnet-1","sig":"32EjdWv91eNfysQTQUREE25y22gHPYDpboAmk3QfBPfWDXr82SgjieEmk8q5pmdYEywx6oF6UGwTSPpC56Kp9oq7"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:26:16.357Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
