Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, in an embodiment of the present invention, the method for querying a transaction status based on a blockchain includes:
step S10, receiving a transaction request initiated by a user;
in this embodiment, the method for querying a transaction state based on a blockchain is applied to the system for querying a transaction state based on a blockchain, where the system for querying a transaction state based on a blockchain includes a request initiating module, and the request initiating module may be used to initiate various transaction requests, or may directly initiate a transaction state query request. The user initiates a transaction request on a client, which may be a mobile client or a computer, and the mobile client may specifically include a mobile phone, a tablet, or an intelligent wearable device, and the like. The transaction request may be a transfer, cash withdrawal, or top-up operation, among other operations. The request initiating module receives a transaction request initiated by a user, and it should be noted here that, when the user initiates the transaction request, the transaction request is transmitted to the request initiating module, and in the process of transmission, the transaction request at least can carry a key identifier for verification by the request initiating module, and can also carry a key identifier ciphertext obtained by encrypting the key identifier by sharing secret information between a data transmission party and a receiving party, i.e. the request initiating module, for verification of identity by the request initiating module. When the request initiating module receives the transaction request, if the verification of the key identifier carried by the transaction request is passed, the request information can be judged to be legal, and the transaction request is received.
In this embodiment, the request initiating module has the address information of the blockchain account. The blockchain account address information may include, but is not limited to, bitcoin address, etherhouse address, and super ledger address. In this embodiment, the transaction request may include blockchain address information or an address matching rule, and the address matching rule may be a matching rule generated according to the blockchain account address information. To avoid this, address matching rules may be generated from the blockchain account address information and bloom filters, as the transaction request requesting the initiation module may inadvertently reveal the wallet bitcoin address information, compromising the privacy of the user.
Step S20, sending a consensus confirmation request to the operator and the node corresponding to the transaction according to the transaction request;
the consensus is a block chain proper noun, a single accounting center does not exist on a block chain, and the account book is recorded jointly through the whole network, so that the problem that how to determine whether a transaction is legal or not, the process of determining whether a certain transaction is legal or not and whether a large packet block recommended by a node is approved by a person is called consensus, and only the block passing the consensus is approved by the whole network is solved.
In this embodiment, after receiving a transaction request initiated by a user, a request initiation module invokes a consensus confirmation module to send a consensus confirmation request to an operator and a related node corresponding to the transaction. It should be noted that information interaction among the modules includes an information confidentiality mechanism, and the modules carry keys that can mutually confirm identity information, so as to ensure confidentiality and security in the information transmission process.
Meanwhile, when the consensus confirmation module is called by the request initiating module to perform consensus confirmation, the transaction request is sent to the blockchain transaction module, and the transaction is performed after the consensus request is confirmed.
Step S30, after the consensus confirmation request passes, performing the transaction operation corresponding to the transaction request;
and the consensus confirmation module checks the consensus confirmation request, and after the transaction request passes the consensus confirmation, the blockchain transaction module carries out transaction operation according to the transaction corresponding to the transaction request.
Step S40, initiating a polling query according to the transaction time data stored in the blockchain according to a preset condition, and feeding back a query result obtained by the query to the user.
After the transaction operation is completed, the system initiates polling inquiry according to the transaction time stored in the block chain, and inquires the transaction at regular time. In the transaction time stored in the blockchain, more than one transaction operation may exist, at this time, the code of the transaction to be queried may be further obtained, each transaction system sets a code corresponding to the transaction system uniquely, and when querying the transaction information, the code may be applied to obtain the unique transaction operation. And finally, feeding back the query result obtained by the query to the user, wherein the feedback mode can be various, for example, the query result can be fed back to the user in a form of sending a short message, or the query result can be sent in a form of sending an email, or other forms can be adopted.
However, it should be noted that the premise of initiating the polling query according to the transaction time stored in the blockchain is that the polling query can be initiated only when the preset condition is met, and query requests that do not meet the preset condition cannot be performed, so that it is ensured that other external programs cannot directly query the transaction information, and the security and confidentiality of the information are further ensured.
The method of the embodiment receives a transaction request initiated by a user; sending a consensus confirmation request to an operator and a node corresponding to the transaction according to the transaction request; after the consensus confirmation request passes, performing transaction operation corresponding to the transaction request; and initiating polling inquiry according to the transaction time data stored in the block chain, and feeding back an inquiry result obtained by the inquiry to the user. By combining the blockchain technology and performing consensus confirmation on the nodes participating in the transaction and the operator, the method of the embodiment can perform the next transaction operation only on the premise that the consensus confirmation is passed, so that the security of the transaction is improved, and when the transaction data is queried, the corresponding transaction data can be queried only when the preset conditions are met, so that the confidentiality and the security of the transaction information in the open network are ensured.
