518. The first terminal device unfreezes the object corresponding to the first information.

After receiving the unfreezing instruction from the blockchain network, the first terminal device can unfreeze the object corresponding to the first information. After unfreezing, the second user can use the right to buy and sell the object corresponding to the first information.

In the business processing method described in Figure 5, a smart contract is generated and uploaded to the blockchain network based on the needs and conditions of both parties. The network completes the digital signature of the electronic documents by both parties, and automatically completes the digital transfer and object freezing according to the signed electronic documents and the smart contracts of both parties, which reduces the process of user participation and thus improves the efficiency.

For example, the smart contract on the chain of investment company A is the first smart contract, the smart contract on the chain of company B is the second smart contract, and the blockchain network determines the investment company A and the company according to the first smart contract and the second smart contract. B can achieve good cooperation, and then generate an electronic contract according to the first smart contract and the second smart contract. After the generated electronic contract is digitally signed by investment company A and company B, it can send a message to the client corresponding to investment company A. Company B transfers the transfer instruction, transfers the money, and freezes the assets mortgaged by Company B. Subsequently, when the deadline of the electronic contract is approaching, if company B has not repaid the investment company A, a prompt message can be sent to remind company B to repay. In the case that Company B repays before the expiration of the electronic contract, the frozen assets of Company B can be unfrozen. When the time limit of the electronic contract is reached and company B has not repaid, the frozen assets of company B can be changed into assets of investment company A, which can be used to mortgage company B's debts.
