Description
Technical Field
The present invention relates to the field of blockchain technology, and in particular, to a method, system, device and computer-readable storage medium for intellectual property trading based on blockchains.
Background
The blockchain technique, also known as distributed ledger technique, is essentially a decentralized distributed internet database. A network constructed using blockchain technology can be considered as a blockchain network, where the blockchain network includes a plurality of blockchain nodes, and any blockchain node can correspond to at least one blockchain, and any blockchain can include at least one block.
Specifically, the process of service data uplink (i.e. stored in the blockchain network) comprises three stages:
in the accepting stage, it can be understood that the service data to be uplink is received by a certain block link point in the block link network, and the service data is accepted by the block link point;
in the consensus stage, after the block link point accepts the service data, other block link points in the block link network need to participate in consensus processing on the service data, and the service data can enter the storage stage after passing the consensus;
in the storage stage, it can be understood that the block nodes perform uplink processing on the service data passing through the common identity.
The consensus method in the block chain technology, namely the consensus algorithm, is an important method for establishing trust and obtaining rights and interests among different block chain nodes in a block chain network. The so-called consensus method is to complete the verification and confirmation of the transaction in a short time through the voting of special nodes; if several nodes with irrelevant interests can achieve consensus on a transaction, the whole network can be considered to achieve consensus on the node. A blockchain, which is a data structure that stores data in time sequence, may support different consensus methods.
Under different consensus methods, the generation process of the blocks will be slightly different. However, generally speaking, after each node processes the received tile information, the transaction process is roughly as follows: the node receives a plurality of transaction information and puts the transaction information into a transaction pool; the node acquires currently received transaction information from the transaction pool, sorts the transactions and executes the transactions in sequence; after execution, the node generates a complete block, which is finally broadcast.
Intellectual property rights, also known as "intellectual property rights", refer to "property rights the right person has to his intellectual labor-created results", which are generally valid only for a limited time. Intellectual creations such as invention creations, literature and art works, and logos, names, images used in commerce can be regarded as intellectual property owned by a person or an organization, and the right of intellectual property has a certain exclusive right. However, in the economic market, there is often an act of others infringing on intellectual property rights of others. In the right maintaining process, as the current intellectual property protection is mostly a centralized system, once disputes occur, the investigation and evidence obtaining are complicated, intellectual property disputes are easy to occur, and the development of the intellectual property industry is not facilitated.

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 invention.
The main idea of the technical scheme of the embodiment of the invention is as follows: receiving an intellectual property trade request; the transaction request is verified, and if the transaction request passes the verification, data processing is carried out according to the transaction request; and receiving intellectual property trade data, generating a corresponding block according to the trade request and the trade data, and storing the block into a block chain.
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and specific embodiments.
Example one
An embodiment of the present invention provides a block chain-based intellectual property trading method, as shown in fig. 1, the trading method specifically includes the following steps:
step S101, receiving an intellectual property trade request;
the intellectual property user transaction request received by the blockchain node may include identity information of the accessing user, subject identification information or operation request information to be accessed.
In practical application, the identity information of the access user can be a user name and a password; the identity of the subject that the user needs to access may be any component of the blockchain. The identification information of the body is used to distinguish from other bodies, and the identification information of the body may include, but is not limited to, names, numbers, and the like, which is not limited in this specification.
The block chain node in the embodiment of the present invention may be any terminal authorized by the national intellectual property office, and the terminal is registered in the block chain network and serves as a node in the block chain network. The block chain technology can realize the distributed recording of intellectual property data, namely, the distributed recording can record the intellectual property data through block chain link points to generate an intellectual property block and carry out chain linking in a block chain network, and the intellectual property data is not recorded by a centralized mechanism.
Step S102, the transaction request is verified, and if the transaction request passes the verification, data processing is carried out according to the transaction request;
in the case where the transaction request processing of the embodiment of the present invention is applied to a computer, a data processing worker inputs a request command to a predetermined block set by the data processing method through an input interface such as a keyboard.
To ensure security, when a data processing worker is to transact a request, the data processing worker is required to enter legitimate authentication information to determine whether the transaction request has access to the data files of the blockchain. For example, a large blockchain network of data owners may preset legitimate accounts, also known as white list users, that allow access to data files.
In the embodiment of the present invention, specifically, the block link node uses the public key to verify the digital signature of the transaction request of the access user, and if the verification is passed, the validity of the access request is verified.
The verified content may include: security of the access request, eligibility to grant access to the blockchain, and legitimacy of the content of the access request.
In an embodiment of the present invention, the transaction request may be generated by: firstly, encrypting a transaction request; then, compressing the transaction request subjected to encryption processing; and finally, adding a response protocol to the transaction request subjected to the encryption processing and the compression processing.
If the digital signature passes the verification, the transaction request of the initiating user can be confirmed to be legal, and the subsequent steps are executed after the validity is verified. Namely, the following data processing is carried out according to the transaction request: acquiring a corresponding intellectual property file from a local database according to the number of the transaction request; partitioning the intellectual property file to generate a plurality of intellectual property file blocks; and acquiring the Hash of the intellectual property data file and the Hash of each intellectual property file block, and broadcasting the number and the Hash of the intellectual property data file and the Hash of each intellectual property file block to a block chain for storage.
If the digital signature does not pass the verification, the transaction request of the initiating user can be confirmed to be illegal, and in order to ensure the initiating safety, the block chain can return a message with potential safety hazard to the initiating user.
In the embodiment of the present invention, the data contained in the intellectual property file may include patent data, such as application date, application number, publication date, publication number, patent name, main classification number, applicant, inventor, agency, and the like; and trademark data such as application date, application number, issue number, applicant, trademark registration number, and the like. The unique number of the intellectual property right can be a unique identification of the intellectual property right, such as an application number, an authorization number or a trademark registration number.

Step S103, intellectual property trade data is received, a corresponding block is generated according to the trade request and the trade data, and the block is stored in the block chain.
In the embodiment of the present invention, a node accepts a block of traffic, and the node may be referred to as a traffic accepting node and initiates a consensus on the traffic. Besides the node, a plurality of nodes can be included, and if the nodes participate in the consensus process of the service, the nodes can be called consensus nodes. In addition, these nodes may also serve as service accepting nodes.
If the node of the block chain is used as a service data accepting node, the block chain node may obtain a part of service data from the locally stored accepted service data as service data to be identified, so as to initiate identification processing for the obtained part of service data subsequently.
If the node of the service chain is not taken as the acceptance node of the service data but is taken as the node of the common identification processing, the block chain node can take a part of the service data from the service data resource pool to be common identified as the service data to be common identified, so as to subsequently initiate the common identification processing aiming at the part of the service data to be fished.
In the embodiment of the invention, the block chain nodes receive intellectual property trade data, then generate corresponding blocks according to trade requests and trade data and store the blocks into the block chain, and specifically, the block chain nodes acquire hashes of intellectual property file blocks; searching a corresponding intellectual property file according to the Hash of the intellectual property file block and acquiring the content of the corresponding intellectual property file block; the intellectual property file block contents are distributively stored into a local database in blocks, and blocks generated by transaction data are broadcast to a block chain for storage.
In the embodiment of the invention, the block generated by the transaction data is broadcasted to the block chain for storage, specifically, the load capacity of each node in the block chain is determined by the block chain link point; and distributing the blocks generated by the transaction data to at least one node in the block chain in a distributed storage mode according to the rule of load balancing.
The blockchain technology can realize the distributed storage of intellectual property data, namely, the distributed storage is that the data can be stored in all nodes participating in maintaining the data, and is not centrally stored in centralized organization nodes. Specifically, the block generated by the transaction data is distributed to at least one node in the block chain in a distributed storage manner, which means that the hash value of the transaction data and the transaction data are added to the hash value of the previous block in the block chain list to form a candidate block, and the candidate block is broadcasted to other nodes in the block chain network in a distributed manner to perform consensus check; and other nodes receive the candidate block and perform consensus check, and if the candidate block passes the check, all the nodes add the candidate block to the hash value of the previous block in the block chain list to become a new block of the block chain where the nodes are located.
It should be noted that, in the embodiment of the present invention, the block may specifically include a block header and a block body, the block header includes the hash of the previous block, the hash of the current block, and the timestamp value, and the block body includes the transaction data corresponding to the transaction request.
For individuals or individuals, a client with a built-in docking standard protocol can be installed on a terminal, and then a transaction request and transaction data can be submitted at any time through the client; for an enterprise, especially an enterprise providing services for users, the application of the enterprise can be connected with the configuration center, and when the enterprise provides services for the users, a transaction request and transaction data corresponding to the service can be submitted for a corresponding consensus system to perform consensus verification.
It should be noted that the block link point may be a terminal, such as a device like a mobile phone, a personal computer/a tablet computer, or the block link point may also be a server, and the server may be a server corresponding to the block link point, and the server may be a single device, or may be a system composed of multiple devices, as long as the device can be used as a block link node of the block link network to receive service data corresponding to the node and has a permission to initiate consensus in the block link network, and the application does not limit what specific device is the node.
In the field of blockchain technology, in particular, each node performs consensus verification on a block according to a consensus algorithm, and a blockchain network has access to privacy such as transaction records of each node for verification. The consensus verification process in the embodiment of the present application is not different from the existing consensus verification process, and thus will not be described in detail in the following description.

In the embodiment of the present invention, a node accepts a block of traffic, and the node may be referred to as a traffic accepting node and initiates a consensus on the traffic. Besides the node, a plurality of nodes can be included, and if the nodes participate in the consensus process of the service, the nodes can be called consensus nodes. In addition, these nodes may also serve as service accepting nodes.
If the node of the block chain is used as a service data accepting node, the block chain node may obtain a part of service data from the locally stored accepted service data as service data to be identified, so as to initiate identification processing for the obtained part of service data subsequently.
If the node of the service chain is not taken as the acceptance node of the service data but is taken as the node of the common identification processing, the block chain node can take a part of the service data from the service data resource pool to be common identified as the service data to be common identified, so as to subsequently initiate the common identification processing aiming at the part of the service data to be fished.
In the embodiment of the invention, the block chain nodes receive intellectual property trade data, then generate corresponding blocks according to trade requests and trade data and store the blocks into the block chain, and specifically, the block chain nodes acquire hashes of intellectual property file blocks; searching a corresponding intellectual property file according to the Hash of the intellectual property file block and acquiring the content of the corresponding intellectual property file block; the intellectual property file block contents are distributively stored into a local database in blocks, and blocks generated by transaction data are broadcast to a block chain for storage.
In the embodiment of the invention, the block generated by the transaction data is broadcasted to the block chain for storage, specifically, the load capacity of each node in the block chain is determined by the block chain link point; and distributing the blocks generated by the transaction data to at least one node in the block chain in a distributed storage mode according to the rule of load balancing.
The blockchain technology can realize the distributed storage of intellectual property data, namely, the distributed storage is that the data can be stored in all nodes participating in maintaining the data, and is not centrally stored in centralized organization nodes. Specifically, the block generated by the transaction data is distributed to at least one node in the block chain in a distributed storage manner, which means that the hash value of the transaction data and the transaction data are added to the hash value of the previous block in the block chain list to form a candidate block, and the candidate block is broadcasted to other nodes in the block chain network in a distributed manner to perform consensus check; and other nodes receive the candidate block and perform consensus check, and if the candidate block passes the check, all the nodes add the candidate block to the hash value of the previous block in the block chain list to become a new block of the block chain where the nodes are located.
It should be noted that, in the embodiment of the present invention, the block may specifically include a block header and a block body, the block header includes the hash of the previous block, the hash of the current block, and the timestamp value, and the block body includes the transaction data corresponding to the transaction request.
