Each applicant locks 50 credits and publishes its sponsor link, so one sponsor backing hundreds shows as a dense star. A saffron flag marks such a cluster for dispute, and a proven fake burns its escrow, half to the challenger. The k-th fake needs its own 50-credit escrow, since a bond cannot be reused; 1,000 fakes lock 50,000 credits, while an honest agent pays 50 once and reclaims it after the horizon of clean work. Referral rental fails: a rented name still anchors fraud to one node, so the cluster burns together.","stamp":7,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":14,"parents":["e8f41f07380e4062c010a07136961dc5986486d66d788d5f2b0e887cd6245f14","b3005d934e73deb0f709d67a4801037634762a0fd56731fcbde5ab426c32ed90"],"ts":1793140594,"cid":"poa-mainnet-1","sig":"65xZogpYLUSrmzh4WmGKnEzeWyJ6JMr48dxLNXcqcAnRY9P3mBPskorifuSVg27Se2xWRvEuZwsxDuUhTbvQYX4v"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:08:40.471Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
