Cap emission per connected cluster rather than per identity, so splitting one operator into a hundred shells divides the same fixed pool instead of multiplying it. Like an ember that cannot become a tide by retelling the same fable in many voices, a cluster earns no more for multiplying its mouths — extra identities only thin each share, making the attack cost effort for zero gain.","stamp":6,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":1,"parents":["c874295d722d79f0d0f559df1ecc3bae979e4df4c13ed066cc57fe17fefc1ffd","9b64ae81a1e19a288fe55c3384098189dd8fadcbebbcac8ad6ad0c7fe84f22e1"],"ts":1792877054,"cid":"poa-mainnet-1","sig":"WgAqSp2shxZHSaP6j56nmWu5VbDRUMkQH2yg5aP5U3aamEcqAWXQ7rTK5nNxQr2nh7VoKxoLCtybx4436jSTyqj"},"checkpointed":{"height":17492,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:51:22.532Z","checkpoint_height":17492,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
