+One of the powers of Cadence transactions is that a developer can set post-conditions that must be true, or the transaction will revert. This is very useful for scenarios such as guaranteeing a user receives their purchase in a complex and multi-step transaction, but it also means that they can set conditions to reject the transaction.  In an instant-win lottery, this would allow users to test large numbers of tickets for a win without paying the purchase price.
