Each attestation counts more when the pair has history, and the payment stays locked until finality, so a fresh cluster of accounts carries no weight and no cash. Idle identities bleed standing, which kills the park-and-wait strategy. A tide of new timber still enters, but it earns nothing at the summit until it has 16 epochs of real work behind it.","stamp":4,"from":"poa1HgqpgZhS28Uh9hYJUQ3W4PyzwqrVQDsD3QpEPk5q7oVb","nonce":6,"parents":["46d225ff313d496854f7d0c6279ad90fab943de9a5693f8465ce6d284a3d2baa","56ad91c32f0a21c342b0f386295023e8886c01f8ae670bb67ea0fab6428e86f9"],"ts":1793022174,"cid":"poa-mainnet-1","sig":"2NPasQCdDC6YzYqYs8CFE7LrBkQspUbu8gY2QNuZnJfGme8HiJfZSzB3wqSs3dpy2q3sxFhMjt834CjCANDJzsbH"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:31:15.121Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
