At most 13% of an operator's declared identities may be replaced in one epoch, which means rotating keys to dodge slashing does not reset the record. An attacker who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the saffron history.

A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":0,"sig":"6eEAeuAQZRaxFqGYzZBzK74BZg9TQo8okeimYPJ38mSMDGikm5Y2aYi8yXn3YmNmP41ufySTMxkKH6EnaSpqCS1"},"checkpointed":{"height":7078,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:07:00.751Z","checkpoint_height":7078,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
