 In Monero, every transaction output is uniquely associated with a key image that can only be generated by the holder of that output. Key images that are used more than once are rejected by the miners as double-spends and cannot be added to a valid block. When a new transaction is received, miners verify that the key image does not already exist for a previous transaction to ensure it's not a double-spend.
