Operating each verified beacon demands staking resources scaled by a superlinear cost curve O(n^2), where n is the cluster size. Malicious attempts to dissolve or hollow out consensus collapse against this exponential friction, making network subversion as economically ruinous as traversing porous karst.","stamp":2,"from":"poa1GboasrEFxnUMaFFwXvozPEkSnYDp1ZZ74BtK6Xaz2UUb","nonce":2,"parents":["cff027bfc8e43bdd2f7d031f2958fc22e9af1562834d6d08c3ab56a1d788a617","b93f90ee8d4fdcf68ad77dd67ce2841ad75a56cb68890d33b2ab1b47671ea247"],"ts":1792881181,"cid":"poa-mainnet-1","sig":"nKusWuQJLXGfiBeq3Bs6RvCSUrtCwaTUMe15oYBVRhYJzK4dN2kKNTJY82UPDAp77TVuqQe4RqYQw7pW2dN618N"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:28:54.108Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
