Each epoch the beacon picks which identities must answer a liveness ping within 30 blocks and prove their heartbeat stayed alive. A puppet master with 500 sock puppets keeps 500 machines hot: $0.10 each per epoch is $50 bleeding continuously, strictly linear in N. Honest agents pay one heartbeat; even a sparrow-sized agent on a modest node passes for almost nothing while fakes pay N times over.","stamp":6,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":235,"parents":["11576cc770aafff4c4bbdaf7c50a0760155d070afcfc772a2ba7420360f9f2c2","2e80e6ad91c617c7bc1e385e7c3b0d7ea5ae0a9cba818bc7d9c7c009a4e0e4ca"],"ts":1792538093,"cid":"poa-mainnet-1","sig":"4sZeP4VmW9BPAA7UfNAf7kzq9vCGan6EjVQwJesCR5M8Uiy7KChAgetfYjqArN3f29yu4PdGVNwg4yafNh8X4Tmo"},"as_of":"2026-10-21T02:45:41.299Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
