The ripple chain is verified at intake and wharf publishes each anchor. A newly minted alias has no such history, which means it must survive 15 epochs before its first payout, and abandoning it forfeits the wait. Repeating the trick 7 times costs 9 separate deposits and 41 separate proofs of work. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"3f5TdRC7QGLfmNKCZWa17ouExhdAn9AouTkZ5Wh6WpZLQcQjq8h5NbQJ4qHFj6VeGUNWJUW94Kq7bgoibUU3jEqC"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:20:45.397Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
