For example, in the blockchain network, the second account registered on the node device has: the second account A logged on the first node device, the second account B logged on the third node device and the second account C logged on the fourth node device, the first account entrusts the second account A to initiate a transaction for the first account A, therefore, the first node device signs the transaction data in the received first transaction information to obtain a second digital signature A, and the subsequent second node device with transaction execution qualification can know that the second account A initiates a transaction for the first account in the second account A, the second account B and the second account C by processing the second digital signature A.

Referring to fig. 4, fig. 4 is another transaction method proposed in the embodiment of the present application, which may include, but is not limited to: S401-S403.

Under the condition that the transaction data passes the verification, the second node equipment processes the transaction data according to the second transaction information and the second virtual resource, and the reliability of transaction execution can be guaranteed.

In the embodiment of the application, the second node device receives the second transaction information and the second virtual resource of the first account sent by the first node device, and after the transaction data in the second transaction information is verified, the transaction data is processed according to the second transaction information and the second virtual resource, that is, the second node device executes a transaction for the first account, so that the problem of the transaction of the first account which does not have the transaction initiation qualification and the transaction execution qualification is solved.

Fig. 5 is another data transaction method proposed in the embodiment of the present application, which may include, but is not limited to: S501-S505.

S501: and the second node equipment receives the second transaction information of the first account and the second virtual resource sent by the first node equipment.

Step S501 in this embodiment may specifically refer to the execution process of step S401 in the above embodiment, and is not described again in this embodiment.

S502: and the second node equipment determines the relation between the resource quantity of the second virtual resource and the resource quantity of the target virtual resource.

The target virtual resource is a virtual resource required by the second node device for processing the transaction data according to the transaction information. The second node device processes the transaction data according to the second transaction information only when determining that the resource amount of the second virtual resource is the same as the resource amount of the target resource, so that the second node device determines the size relationship between the resource amount of the second virtual resource and the resource amount of the target virtual resource before processing the transaction data.

S503: and if the resource amount of the second virtual resource is greater than or equal to the resource amount of the target virtual resource, the second node equipment triggers to verify the transaction data according to the first digital signature and the second digital signature respectively.

And if the resource amount of the second virtual resource is larger than or equal to the resource amount of the target virtual resource, the second virtual resource sent by the first node equipment to the second node equipment is enough for the second node equipment to execute transaction for the first account, the second node equipment triggers to verify the transaction data according to the first digital signature and the second digital signature respectively.

In one implementation manner, if the resource amount of the second virtual resource is greater than the resource amount of the target virtual resource, the second node device sends a third virtual resource to the first node device, where the third virtual resource is a virtual resource corresponding to a difference between the resource amount of the second virtual resource and the resource amount of the target virtual resource, that is, the second node device returns, to the first node device, a surplus virtual resource excluding the target virtual resource required for executing the transaction in the second virtual resource, and the second node device only receives, in the second virtual resource, the target virtual resource required for executing the transaction in the first account.

In an implementation manner, the second virtual resources are from multiple second accounts, that is, the first account delegates multiple second accounts to initiate a transaction instead of the first account, and the first node device acquires the multiple second virtual resources. After receiving the plurality of second virtual resources, the first node device determines whether the sum of the resource amount of each second virtual resource is equal to the resource amount of the target virtual resource. And if the sum of the resource amount of each second virtual resource is equal to the resource amount of the target virtual resource, which indicates that the second virtual resource received by the second node equipment is enough for the second node equipment to execute transaction for the first account, the second node equipment triggers to verify the transaction data according to the first digital signature and the second digital signature respectively.

S504: and if the resource quantity of the second virtual resource is smaller than that of the target virtual resource, the second node equipment sends the indication information to the first node equipment.

The indication information is used for indicating that the second virtual resource is not enough for the second node device to process the transaction data according to the transaction information. If the resource amount of the second virtual resource is smaller than the resource amount of the target virtual resource, it is indicated that the second virtual resource sent by the first node device is not enough to enable the second node device to execute the transaction for the first account, so that the second node device generates indication information and sends the indication information to the first node device to prompt that the second virtual resource sent by the node device by the first node device does not meet the condition of executing the transaction and needs to send a new virtual resource to the second node device.

S505: and the second node equipment verifies the transaction data according to the first digital signature and the second digital signature respectively.

Specifically, the second node device performs hash operation on the first digital signature to determine whether the first account is an account requesting to initiate a transaction; the second node device hashes the second digital signature to determine whether the second account is an account eligible for transaction initiation.

The second node device carries out hash operation on the first digital signature to obtain a first target hash value, the first target hash value is compared with the one-to-one correspondence relationship between the hash value stored by the node device and the account to determine a first account corresponding to the first target hash value, and whether the determined first account is an account without transaction initiation qualification is verified, namely whether the first account is an account requesting to initiate a transaction is verified. And the second node equipment performs hash operation on the second digital signature to obtain a second target hash value, compares the second target hash value with the one-to-one correspondence between the hash value and the account stored in the node equipment to determine a second account corresponding to the second target hash value, and then verifies whether the determined second account is an account with the transaction initiation qualification.
