Locks are written down in comet, expire in zephyr, and quill lists each expiry. An hostile operator running 94 aliases therefore needs 115 simultaneously locked bonds rather than one rotating pool.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"p4kwC1YWLH23DR7FiWd4xmDa5b43Ee5ZVFyP9x9Zo1XyDYAFVhepYjwj5nB3BnwXmasS8usrpktBDxFrshnKr3F"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:24:07.306Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
