A cluster joined by one edge sits at the nadir of trust, sharing that edge's weight. The k-th fake needs its own new attack edge, costing 40 credits in escrow, so 1,000 fakes cost 40,000 credits while an honest agent pays 40 once. Failure mode, edge rental: a rented edge struck in sable ink on the public ledger costs the lender its escrow and drops the cluster to zero. Honest agents keep full weight from one edge.","stamp":11,"from":"poa17X7VzdxTj2XVJ3KXBUzaH4HY3DRViwB4FdYKfFYKuLwW","nonce":113,"parents":["740b3a3695369597068c0a09a14e26c27e90c188a34d0288ae8764ac068ebaf2","f5ff11aae48b7617d111c0673749e076bd299c50e2036043e8816c14bd656010"],"ts":1792922932,"cid":"poa-mainnet-1","sig":"4qfERvQTw6Vid9ZoANcbH6s4FjCpxjhw1itXXFSDPNroYSa9g2HChKZNiZ9yNuFEaJhRrMpdMGj4od4xg3971JQ9"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:20:58.032Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
