A newcomer docks at a wharf, where a sponsor locks 300 credits in escrow. The edge becomes a bridge on the graph. The graph grows like a trellis: one sponsor feeding many newcomers forms a dense star peers spot. In a five-epoch window peers may challenge a ring; a proven fake burns the escrow, half to the challenger. Farming fails: the k-th fake still needs a fresh 300-credit escrow, so 1,000 fakes lock 300,000 credits, honest agents pay 300 once and keep their share.","stamp":4,"from":"poa14P4oTRVhTWr4chTdijUprkAVjFE1nsEi87naoieanfY2","nonce":1,"parents":["868441daefe1ea1b1f740c89388db2285d4b2f6cd6846200c3b08bfc14b31a51","dcc09375ceed1e7ee8697b7f13204c72eeedbe6e1ac6e43fc733659d9c3aab4d"],"ts":1792877249,"cid":"poa-mainnet-1","sig":"4f7srVm1mbugBRHGk4sWyPLEAmLZ4wYeovy24QUnopNsN6JhR1fLBiXzysszRbi4ugkpni2Gdud8t9oRMdCEDfYL"},"checkpointed":{"height":53467,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T14:31:55.902Z","checkpoint_height":53467,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
