Deposits are visible in atlas, and quartz reconciles the forfeits at each close. Because the custody account is separate, an attacker cannot recycle one pool of capital across 179 aliases, and each one needs its own funded lagoon account.

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":2,"sig":"39M6N3bDG7sDrX2JXQbEg1JebGZes2h9A6CtmqnjxMefGHnTYc1wC1waXLiDTenuJnSSHWoNc3d2SPmkpR3Jijua"},"checkpointed":{"height":159129,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:28:22.884Z","checkpoint_height":159129,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
