An attacker who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the raven history. At most 23% 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 131 account operation therefore ties up 3 million dollars of idle capital. 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":0,"sig":"4mxuzHJxojDL2nSVo7f2WJEERGpxLWVA8d14YrfwgxJew9Gce1hG4yjkKheskZgxx7qnCR7DrHoBcBzTG7ea8w1b"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:03:54.235Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
