A first logic circuit included in a processor receives a first digital signal, where the first logic circuit includes a special purpose register, a comparator, and an adder, where the special purpose register stores a first resource balance for executing a smart contract, where the first digital signal includes a resource deduction quota corresponding to a code set in the smart contract. The first logic circuit reads the first resource balance from the special purpose register. The first logic circuit compares, using the comparator, the first resource balance with the resource deduction quota. In response to the first resource balance being greater than or equal to the resource deduction quota, the first logic circuit subtracts, using the adder, the resource deduction quota from the first resource balance to obtain a second resource balance. The first logic circuit stores the second resource balance in the special purpose register.
