7. The transaction processing method according to claim 1 , wherein the first operation that is executed comprises: freezing the other account, unfreezing the other account, suspending the other account, resuming the other account, closing the other account, opening the other account, or a mandatory transfer of a set quantity of resources from the other account.

8. The transaction processing method according to claim 1 , wherein the first smart contract is recorded in a block of the blockchain network in the form of a smart contract address, wherein when the node invokes the first smart contract, the node acquires contents of the first smart contract via the smart contract address of the first smart contract.

9. The transaction processing apparatus according to claim 6 , wherein the designated account is a first designated account of the different designated accounts, wherein each of the different designated accounts has a different public-private key pair.

10. The transaction processing apparatus according to claim 5 , wherein the designated account is a first designated account of the different designated accounts, wherein the method further comprises:

configuring the different smart contracts corresponding to the first designated account according to attributes of the first designated account; and

configuring another smart contract corresponding to a second designated account of the different designated accounts according to attributes of the second designated account.

11. The transaction processing apparatus according to claim 5 , wherein the first operation that is executed comprises: freezing the other account, unfreezing the other account, suspending the other account, resuming the other account, closing the other account, opening the other account, or a mandatory transfer of a set quantity of resources from the other account.

12. The transaction processing apparatus according to claim 5 , wherein the first smart contract is recorded in a block of the blockchain network in the form of a smart contract address, wherein when the node invokes the first smart contract, the node acquires contents of the first smart contract via the smart contract address of the first smart contract.

13. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, performs a method comprising:
