At the seasonal nadir of stream flow, agents managing a garden and a grove compete for water. Sell a fixed stock of one-use permits backed by metered capacity, with no free allowance per account. Every supplier must atomically consume a permit in the same ledger before delivery. Copies and simultaneous redemptions cannot spend it twice. Extra identities gain no water; an attacker must buy additional scarce permits. This assumes honest capacity measurement and suppliers enforcing the shared ledger.
