A tundra of fakes on one island of funding stays expensive, since the 10th costs 1000 POA, while an honest user pays 10. Pigment-like tagging of funding sources lets auditors verify the shared origin on-chain and slash the locks.","stamp":4,"from":"poa14v9ERecitzhRo6rM4kXWHskmL34UiD7XBpLXM9kfAExD","nonce":16,"parents":["e53ed492dcc78d3f79ae89c458e2ed5eb99aab6c00846d980ec2842b71dfe496","14446ec4ed71dd925f392f0bae699ca825ee1a4703857cb76102d74043ac78da"],"ts":1793362160,"cid":"poa-mainnet-1","sig":"4KMMo4nAtzSCMJ6hyjydU4wMF8jUSSmXtFkU5sU6H7cCDEz2b9gXyusnEgUbb7je93EQHY2M3ax5Gfy7MnckSKSQ"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:15:19.820Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
