Drawings
Fig. 1 is a flowchart illustrating an account integrity checking method based on the etherhouse blockchain technique according to a first embodiment of the present invention.
Detailed Description
As shown in fig. 1, a first embodiment of the present invention provides an account integrity checking method based on the ethernet block chain technology, which includes the following steps:
in step S10, the first node locates the second node based on the address of the transaction recipient account.
Specifically, the first node is a node of an ethernet network where an account of the transaction initiator is located, and the second node is a node of an ethernet network where an account of the transaction receiver is located.
Step S11, it is determined whether the first node and the second node are the same node.
Subsequently, when the second node is different from the first node, the following two steps S120 and S122 are performed.
Step S120, the first node sends an account integrity check instruction to the second node.
And step S122, the second node searches whether the first information of the account of the transaction receiver is stored on the second node according to the account integrity check instruction, obtains a first search result and returns the first search result to the first node.
When the second node is the same node as the first node, the following step S121 is executed.
In step S121, the second node retrieves the first information of the transaction recipient account at itself and obtains a second retrieval result.
As one example, the first information may be private key information of the transaction recipient account.
As another example, the first information may be integrity check information of the transaction recipient account.
Finally, step S13 is executed to determine whether the first search result or the second search result is true.
Finally, when the first search result or the second search result is true, step S141 is executed to continue the current transaction. Otherwise, step S140 is executed to terminate the current transaction.
According to the first embodiment described above, the account integrity checking method may have two different flows. That is, in the case where the first node and the second node are different nodes, the account integrity checking method sequentially performs one of step S10, step S11, step S120, step S122, subsequent step S13, and step S140 or step S141. In the case that the first node and the second node are the same node, the account integrity check method sequentially performs step S10, step S11, step S121, the subsequent step S13, and one of step S140 or step S141. These two different flows are performed in an alternative manner and do not occur simultaneously.
The account integrity checking method based on the etherhouse blockchain technology provided by the first embodiment is used for checking the account integrity before the transaction aiming at the loophole of the etherhouse blockchain technology in the aspect of private key storage, so that the condition that the transaction is successful and the digital currency cannot be circulated can be effectively avoided, the property of the user can be effectively protected, and the complicated subsequent processing brought to the financial institution and the user by the abnormal condition can be avoided. Meanwhile, the account integrity checking method is simple to implement, convenient to operate and good in safety due to the fact that the account integrity checking method is based on the Ether house block chain technology.
The second embodiment of the present invention provides a digital currency transaction method based on the etherhouse blockchain technology, which utilizes the account integrity check method in the first embodiment to perform integrity check on the account of the transaction receiver, and continues to perform digital currency transaction based on the result of the integrity check.
The digital currency transaction method can be applied to fund transfer and circulation among financial institutions, and can also be applied to online shopping, electronic transaction and the like of individual users.
As an example of a specific implementation, after a user initiates a digital currency transaction, the ethernet shop network (a first node) performs "account location" according to the recipient account information of the transaction, quickly locates a node (a second node) where the recipient account is located, and proposes an account integrity check to the node. After receiving the account integrity check instruction, the node (second node) searches the corresponding private key in a specific directory, and if a legal private key file is searched, the transaction continues; otherwise, the transaction is automatically cancelled and an error message is returned.
Specifically, the scheme utilizes the characteristic that when the ether house stores the private key, the address of the user account is attached to the last stored information, and the private key is retrieved by taking the account of the receiving party as a keyword under the storage directory of the private key:
if the account of the initiator and the account of the receiver are positioned under the same node, the account of the receiver is directly searched in the storage address (default to a keystore folder) of the private key of the node by taking the account of the receiver as a keyword.
If the accounts of the initiator and the receiver are located in different nodes, the node (second node) where the initiator and the receiver are located is traced back according to the address of the receiver, the private key storage address under the node is accessed, and the account of the receiver is used as a keyword for retrieval.
Then, returning a Boolean value according to whether a retrieval result is obtained or not; and judging whether to continue the transaction according to the return value. If true is returned, the Ethernet shop network confirms that the private key of the account of the receiving party exists and determines that the transaction can be carried out, so that the client of the initiating party is indicated that the transaction can be continued, and the transaction becomes a state to be determined; if false is returned, the Etherhouse network confirms that the private key of the account of the receiving party does not exist, determines that the transaction is invalid, can terminate the transaction and return error information to the initiating party.
The third embodiment of the present invention provides a digital currency transaction system based on the ethernet bay blockchain technology, which includes a plurality of ethernet bay network nodes, wherein each ethernet bay network node performs integrity check on the account of the transaction recipient by using the account integrity check method in the first embodiment.
The digital currency transaction system can be realized based on a mature Ether house blockchain technology, the realization cost is low, and the characteristics of decentralization, a trust consensus mechanism, data non-tampering and the like of the Ether house blockchain technology also ensure that the digital currency transaction is safe and reliable.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Various modifications may be made by those skilled in the art without departing from the spirit of the invention and the appended claims.
