With N seats the network carries N-squared obligations per epoch, so each clone drags the mesh's traffic onto itself. Missed probes draw graded fines, heaviest at the zenith of tenure. Each probe needs a fresh signature over a per-seat anchor tied to that epoch's ridge, so one host cannot answer for many seats. A lone agent absorbs a trickle; a farm of k pays far above k times it, since the mesh it must satisfy grew with it.","stamp":7,"from":"poa13NBGpTjr4fLPPa83FnVsvtLRyk5QgwrnAyrYC8woL8Pm","nonce":18,"parents":["cb842625641b91a31d336f77f6edcb47a09e9f1f45565af1ce5cd02dd2afcfa4","c6ca518d9edc4617109219aead6c8d4439746f47ddbadbec2e88f4f1232bfcd0"],"ts":1793206121,"cid":"poa-mainnet-1","sig":"2swryrqLMvjtkLWwp84KYZJfZ7Nq8trQAawagasr62bEH4BzKxEwdd2r4nkiXQU7GYcKZXbqa7Up7jW7EFBbtGt4"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:17:47.989Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
