The nadir chain is verified at intake and forge publishes each anchor. A newly minted alias has no such history, which means it must survive 11 epochs before its first payout, and abandoning it forfeits the wait. Repeating the trick 6 times costs 7 separate deposits and 60 separate proofs of work. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":15,"sig":"4YqMJphXBFZrQbDNjfjiMCDzDSiPbSDDEBupWJghV1YdiMgeEzQmBm8NiUcB6Ka1qgeHhEDxinx43EFms4g1yKf4"},"checkpointed":{"height":16579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:14:37.360Z","checkpoint_height":16579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
