In order to improve the efficiency of information transaction or information transmission between an information issuing party and an information requiring party, the embodiment of the present application proposes an implementation manner as shown in fig. 2.
Fig. 2 is a flowchart illustrating a method 200 for processing information based on a block chain according to an embodiment of the present application. As shown in fig. 2, the method includes:
s201: and the information demand node sends an information request transaction to the information publishing node.
Correspondingly, the information publishing node acquires the information request transaction through the information transaction contract.
The information request transaction includes a first identifier, where the first identifier is an identifier corresponding to first information issued by an information issuing node in advance, and the information request transaction is used to request the information issuing node to issue the first information.
The information transaction contract is used as an intelligent contract preset in the blockchain, and according to the configured rule, the information request transaction containing the first identifier can be monitored, and after the information request transaction aiming at the first identifier is obtained, the corresponding operation is executed, for example, the operation of sending the first information to the information demand node is executed.
Illustratively, the information publishing node is a blockchain node which logs in an account of an information publisher, and it should be understood that there are multiple information request transactions and other types of transactions in the blockchain, and in this step, the information publishing node only obtains the information request transaction for a first identifier, and the first information corresponding to the first identifier is the information published by the information publishing node.
For example, the first information may include a plurality of pieces of sub information, and accordingly, the first identifier includes a sub identifier corresponding to each piece of sub information, and in this step, the information publishing node obtains the information request transaction for each sub identifier. Further, the corresponding sub information can be sent to the information demand node according to each sub identifier.
S202: and the information publishing node sends the first information to the information demand node according to the first identifier.
Illustratively, the information publishing node sends the corresponding first information to the information requiring node according to the first identifier after acquiring the information request transaction aiming at the first identifier through the information transaction contract. So that the information demand node can acquire, view or use the first information.
Illustratively, before the information publishing node sends the first information to the information requiring node, the first information is signed by a private key of the information publishing node, correspondingly, after the information requiring node receives the first information sent by the information publishing node, the signed first information is verified by a public key of the information publishing node, if the first information is verified, the first information is checked or used, otherwise, the first information is not received.
The information exchange contract is called through the information publishing node, the information request exchange aiming at the first identification is obtained, and the requested first information is sent to the information demand node according to the first identification. The direct interaction between the information issuing party and the information demanding party is realized through the decentralized block chain link points, so that the information demanding party can quickly acquire the required first information, and correspondingly, the information issuing party can timely acquire the digital currency corresponding to the first information, and the information processing efficiency is higher.
Optionally, the information request transaction further includes digital currency transaction information, and the digital currency transaction information is used for indicating the digital currency paid by the information demanding party to the information issuing party in order to acquire the first information.
Optionally, the information request transaction further includes an identifier of the information request transaction and a character string obtained after the information request transaction is signed by a private key of the information demand node.
For information security as well as asset security, it is necessary to determine whether the information request transaction was successful. Illustratively, whether the information request transaction aiming at the first information is successful or not is determined according to the digital currency transaction information and the digital currency value corresponding to the first information, if the information request transaction aiming at the first information is successful, the first information is sent to the information demand node according to the first identifier, wherein the digital currency value is used for indicating the digital currency which is required to be sent to the information issuing party when the first information is requested to be obtained. For example, based on the consensus algorithm, it is determined whether the digital currency paid by the information demand party in the digital currency transaction information is greater than or equal to the digital currency value corresponding to the first information, if the digital currency paid by the information demand party in the digital currency transaction information is greater than or equal to the digital currency value corresponding to the first information, the first information is sent to the information demand node, otherwise, it is determined that the information request transaction fails.
For example, the public key of the information demand node may be used to check the validity of the signed character string in the information request transaction, and the identity of the information demand node is verified, if the signed character string is valid, the verification is passed, and it is continuously determined whether the digital currency paid by the information demand party in the digital currency transaction information is greater than or equal to the digital currency corresponding to the first information; if the signed string is invalid, the information request transaction fails.
The embodiment has no limitation on the sequence of the process of determining whether the information request transaction is successful and the process of acquiring the information request transaction through the information transaction contract. For example, it may be determined whether the information request transaction is successful, and after the information request transaction is successful, the information request transaction for the first identifier is obtained through the information transaction contract; or the information request transaction aiming at the first identification is obtained through the information transaction contract, and then whether the obtained information request transaction is successful or not is determined.
