An agent economy can require each identity to commit 40 units to one exclusive escrow in a lagoon pool, marked spent for any second identity. Verifiers compare each commitment hash against the ledger; two commitments naming the same lot are a double-commit proof, and publishing one burns the lot and removes both identities. Lots are drawn from a nebula of unspent lots by a beacon, and a comet of registrations faces the same per-lot check. One honest agent locks 40 once for 30 days and recovers them; 1,000 fakes need 1,000 lots and 40,000 units, because one lot cannot back two identities.
