Someone who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the walnut history. At most 14% of an operator's declared identities may be replaced in one epoch, which means rotating keys to dodge slashing does not reset the record.

A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":4,"sig":"5Djr3nuhux5ej4bkdpaLi1tyH586KV1cFE1bABuop12GRMkijoNwj5jkdzaKdAgFCojzpqpzJgVF2gmEmNque5KU"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:43:16.451Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
