An farming party who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the quartz history. At most 17% 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 library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"3FguPu2pQ3WnHF4MvhBGna1mgobg3Y8etFUvhqx4nz7aaMzUNyDT4njYpGuTfCun5r7AEvVJkNwVmyGXcNou5Y6m"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:59:59.620Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
