The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The information processing method provided by the embodiment of the invention is applied to the target network, and the target network consists of a plurality of nodes, and each node in the plurality of nodes is used for storing the block data. For example, the method applies a point-to-point (P2P, PeerTo Peer) network, the P2P network consisting of a plurality of nodes, each node for storing block data, forming a block chain.
The information processing system to which the information processing method is applied may be a distributed system formed by connecting a client, a plurality of nodes (any form of computing device accessing a target network, such as a server, a user terminal) through a network communication form, corresponding to an application scenario. Taking a distributed system as an example of a blockchain system, referring To fig. 1, a schematic structural diagram of an example of a distributed system 100 applied To a blockchain system provided in this embodiment of the present application is shown, where the system is formed by a plurality of nodes 101 (computing devices in any form in an access network, such as servers and user terminals) and clients, and a Peer-To-Peer (P2P, Peer To Peer) network is formed between the nodes, and the P2P Protocol is an application layer Protocol operating on top of a Transmission Control Protocol (TCP). In a distributed system, any machine, server, and terminal can join to become a node, which includes a hardware layer, an intermediate layer, an operating system layer, and an application layer.
Referring to fig. 1, the functions of each node in the blockchain system mainly include: the application function is used for being deployed in the block chain, realizing specific services according to actual service requirements, recording data related to the realization function to form recording data, carrying a digital signature in the recording data to represent a source of the task data, and sending the recording data to other nodes in the block chain system, so that the other nodes add the recording data to the temporary block when the source and integrity of the recording data are verified successfully. An intelligent contract function, which is a computerized agreement, may implement the terms of a contract by satisfying code deployed on a shared ledger for execution when certain conditions are met, for completing automated transactions according to actual business requirement code, e.g., querying ownership record information for auction goods. Smart contracts are not limited to executing contracts for transactions, but may also specify contracts for processing received information, such as authenticating received information. The shared account book is used for providing operation functions of storing, inquiring, modifying and the like of account data, operation record data of the account data are sent to other nodes in the block chain system, the other nodes are used as a response for confirming that the account data are effective after verification, the record data are stored in the temporary block, and confirmation can be sent to the node initiating the operation.
The following describes in detail an information processing method applied to a target network in the present application, and referring to fig. 2, it shows a flowchart of an information processing method provided in an embodiment of the present application, and the method may include the following steps:
s201, receiving an ownership transfer-out request sent by a first node executing the ownership transfer-out of the target object.
And the ownership transfer-out request carries the node identification of the second node which executes the target article ownership transfer-in application. The first node is any one node in the target network, the second node is any node except the first node in the target network, and each node stores the record data.
Specifically, the block link node device acquires a first node, which refers to any one node in the target network, and may be a server or a terminal, and sends a request for transferring ownership of the target object to the first node. Taking an item auction scenario as an example, a first node represents an auctioneer of a target item, and a second node can guarantee participants of the auction scenario. According to business requirements, namely according to which node the target item ownership to be auctioned originally belongs to, any one node can be a seller or a participant.
The ownership transfer-out request not only includes the related attribute information of the target object, but also includes the node identification of the second node which can apply for the ownership. I.e. when the first node sends an ownership transfer-out request, some participation conditions for the second node are generated. And generating a target block according to the ownership transfer-out request, and broadcasting the target block in the target network so that each node in the target network updates the locally stored data record according to the target block. I.e. it can be guaranteed that the data stored locally at the respective node is up-to-date.
Still taking the above auction scenario as an example, the auctioneer may customize the participants or restrict the participants' view with certain conditions when generating the auction request for the item, and then publish auction announcements and rules over the blockchain.
In some embodiments, the method further comprises determining the second node based on the ownership roll-out request, the process comprising:
s2011, the acquire ownership transfer-out request carries a node identifier of a second node that executes the target article ownership transfer-in application;
s2012, analyzing the node identification, and if the node identification comprises a node name identification, determining an initial second node according to the node name identification;
s2013, if the node identification comprises node condition information, acquiring an initial second node meeting the node condition information;
s2014, the identity information of the initial second node is verified, and the initial second node passing the verification is determined to be the target node.
The node identification may comprise a node name identification in some embodiments, and may comprise node condition information. If the node name identifier is included, namely when the first node generates the target article ownership transfer request, the second node which can apply for the ownership of the target article is determined, and the purpose of appointing the participating node is achieved. And the node identification comprises node condition information, namely when the first node generates the target article ownership transfer request, the condition of the node which can apply for the ownership of the target article is determined. After the initial second node is determined according to the node identifier, the identity information of the initial second node needs to be verified, so that the identity verification of the second node is realized.
Still taking the auction scenario of the target item as an example, the auctioneer may specify the participants, or may specify the conditions under which the participants participate, i.e., may invite the participants in a public manner. The auctioneer then publishes auction announcements and rules over the blockchain. If a participant is designated, the participant needs to confirm participation and agree to auction announcements and rules through the blockchain application; if it is a public depreciation, the participant reads the announcements and rules and applies the entry through the blockchain.
S202, an ownership transfer-out request is sent to the second node, and feedback information of the second node for the ownership transfer-out request is received.
After an ownership transfer-out request is sent to the second node, the second node generates feedback information according to the request information, where the feedback information may represent whether the second node participates in the transaction of ownership transfer of the target item, or may represent information that is fed back by the second node and matches the identity or participation condition. Facilitating subsequent authentication of the second node based on the feedback information. The feedback information may also characterize transaction information of the second node for ownership of the target item. Still taking the auction scenario for the target item described above as an example, the feedback information may characterize bid information for the target item by an end user of the second node.
S203, verifying the feedback information once by using the acquired timestamp information of the second node, and determining a target node in the nodes.
Note that, in this embodiment of the present application, the timestamp information of the second node refers to time information when the second node joins the target network, or may be time information when the second node generates the feedback information based on the target network. The target network in this application is a decentralized network, i.e. without third party participation. In a target article auction scene, before bidding starts, participants automatically discover and access to the blockchain network according to the blockchain network deployment, and network delay and the like caused by centralization are reduced to the maximum extent.
In the bidding process, the second node generates feedback information aiming at bidding, the feedback information is automatically discovered according to the block chain network deployment, the condition that the bidding is the same because of cheating of the bidding time or registration of false information does not exist, and the fairness of the bidding process is ensured.
When the feedback information generated by the second node is verified, the verification is carried out according to the timestamp information besides the verification condition reaching the formula, so that the fairness of the verification of the feedback information is ensured. Because the timestamp information is the non-tampered information stored in the block, if the verification is successful, the target node is determined in the second node, and the target node represents the node to which the final target article ownership is transferred. Taking an auction scenario as an example, the auction scenario refers to the participant to which the item being auctioned ultimately belongs.
S204, generating a first target block and a second target block, and broadcasting the first target block and the second target block in the target network so that each node in the target network updates the locally stored data record.
The first target block is a block for recording the target article ownership transfer-out process of the first node, and the second target block is a block for recording the target article ownership transfer-in process of the target node.
The newly generated blocks (e.g., the first target block and the second target block) include the hash value of the block, the hash value of the last block, and the information transfer record from the last block to the new block, as well as the timestamp of the new block. The timestamp may be a time point generated by the new block, or may be a time point when the new block is added to the block chain, which is not limited in the present application.
For consistency of the chain of blocks stored at each node of the target network, after a new block is added to the chain of blocks, the new block is broadcast so that all nodes add the new block to the chain of blocks stored locally at the node. Therefore, the process of transferring ownership of the target object into and out can be recorded conveniently, and subsequent information tracing is facilitated.
The embodiment of the application discloses an information processing method, which is applied to a target network, wherein the target network consists of a plurality of nodes, each node is used for storing block data, and when an ownership transfer-out request sent by a first node for executing the ownership transfer-out of a target article is received, a feedback request aiming at the ownership transfer-out request generated by a second node is verified according to the obtained timestamp information of the second node to obtain a target node; and then generating a first target block for recording the target article ownership transferring-out process of the first node and a second target block for recording the target article ownership transferring-in process of the target node. Therefore, the information in the ownership transfer process of the target object is recorded on the block chain, so that the verification and the recording of the information can be traced. Therefore, the processor processing resources are prevented from being occupied when the information is not credible or complained, and the processing efficiency and the processing accuracy are improved.
Some possible implementations of the embodiments of the present application are described below.
In some embodiments, the timestamp information of the second node includes time information of the second node joining the target network, and correspondingly, the verifying the identity information of the initial second node includes:
and verifying the identity information of the second node according to the time information of the second node joining the target network and the preset time joining condition to obtain the second node passing the verification.
Before the second node participates in the target article ownership transfer application, the second node needs to join the target network, and timestamp information matched with time information of the second node joining the target network is generated when the second node joins the target network. When the identity information of the second node is verified, whether the time information of the second node joining the target network meets a preset time joining condition needs to be judged. The time join condition is generated according to the target item auction announcement issued by the first node on the blockchain and the rule, for example, the deadline of joining the target network, that is, the time when the second node joins the target network is after the deadline, the time cannot pass the verification.
In some embodiments, the verification order for verifying the second node may also be determined according to the timestamp information of the second node, that is, the process may include:
determining a verification sequence by utilizing the acquired feedback information generation time of the second node;
and sequentially verifying the feedback information according to the verification sequence.
Since the time is generated based on the feedback information, the verification order is determined. For example, the verification sequence can be determined according to the sequence generated by the feedback time, that is, the target network deployment automatic discovery is performed, and after the second node is found to generate the feedback information, the feedback information is verified, so that the problem that the feedback information is not received timely and the feedback information verification is omitted is solved. The fairness for the feedback information receiving and verification is realized to the maximum extent.
In order to ensure the security of the information, in some embodiments of the present invention, the related information of the second node or the feedback information generated by the second node may be subjected to preset processing, so that the transfer transaction process of the ownership of the target item is more secure.
Referring to fig. 3, which shows a schematic flowchart of a method for processing feedback information according to an embodiment of the present application, the method may include the following steps:
s301, an ownership transfer-out request is sent to a second node;
s302, receiving feedback information of the second node for the ownership transfer-out request;
s303, processing the feedback information according to a specific data format to obtain target feedback information;
s304, generating a third target block by the target feedback information, and broadcasting the third target block in the target network.
After receiving the feedback information of the second node for the ownership transfer-out request, the feedback information may be generated into a corresponding target block, and then the target block is broadcasted in the target network, so that the node of the target network can record the target block, i.e., obtain the feedback information generated by the second node.
Further, in order to ensure the security of the information, the feedback information may be processed, for example, the feedback information is encapsulated in a specific format, or the feedback information may be encrypted by using an encryption algorithm. And even if other nodes obtain the third target block, the specific content of the feedback information generated by the second node cannot be obtained if the processing authority of the target feedback information is not obtained.
For example, in the scenario of auctioning a target item, anonymous and non-anonymous participation in bidding processes can be adopted in the participants according to an intelligent contract, data is encrypted in the whole process, and decryption and bidding data real-time display are performed according to the function contract rules.
The intelligent contract contains all information about the transaction and only if the requirements are met will the resulting operation be performed. The smart contracts are written and operated according to logic. Obligations in contracts will be enforced in secure and distrusted networks as long as the input requirements are met, that is, as long as the requirements of the code writing are met.
In some embodiments, responsive intelligent contracts are automatically generated based on the identified decreasing means and consensus of the rules. The intelligent contract may be preset or automatically generated, and its form includes but is not limited to forward, reverse, english, dutch, ladder, wintry, etc. And deploy intelligent contracts into blockchains to standardize and constrain the entire bidding process.
Therefore, the embodiment of the present application further includes a process of generating an intelligent contract, that is, generating a consensus verification condition, the process including:
s401, receiving an ownership transfer condition of the target object sent by the first node, and generating a fourth target block according to the ownership transfer condition;
s402, broadcasting the fourth target block in the target network so that the second node acquires the target article ownership transfer condition;
s403, receiving confirmation information of the second node on the ownership transfer condition, and generating a fifth target block according to the confirmation information;
s404, broadcasting the fifth target block in the target network, so that the target network node obtains the confirmation information, and making the target network node agree with the target article ownership transfer condition, so as to obtain the agreement verification condition.
The target item ownership transfer condition issued by the first node refers to the auction announcement and the rule generated by the first node for the target item. The auction notice and the rule are then described in the form of information in the fourth target block. Other nodes can conveniently obtain the information, then other nodes perform public confirmation on the information, and the confirmation information is generated into a fifth target block, so that the target network node can obtain the confirmation information, namely the target network node can achieve consensus on the auction notice and the rules, and a consensus verification condition is obtained, namely an intelligent contract for standardizing and restricting the auction behavior in the auction process is generated.
Because the transaction information generated in the ownership transfer process of the whole target object is recorded in the block of the target network, the transaction result is simultaneously sent to all parties in the blockchain application after the ownership transfer is completed. In response to receiving an information backtracking request of a request node of the target network, backtracking information matched with the information backtracking request is acquired in the target network block; and sending the backtracking information to a request node. The requesting node may be any node in the target network in the embodiments of the present application.
In the scene of auction of the target object, after the bidding is finished, the bidding result simultaneously sends the bargaining result to each party on the block chain application, and each party can perform process compliance check, audit, complaint, tracing and the like according to the intelligent contract as required.
Referring to fig. 4, a schematic diagram of an application scenario of real-time bidding provided by an embodiment of the present application is shown, in the real-time bidding process, including a bidding party 501, a participant 502, and a blockchain 503, where the participant may be a plurality of participants. The process comprises the following steps:
