Before carefully explaining the article publishing system and method based on the blockchain technology, first explain the blockchain technology.

Encryption currency technology uses blockchain technology to realize the storage of decentralized accounts. Furthermore, in blockchain technology, each block has at least one transaction data, and multiple blocks are connected in series to form a block chain. Each block in the blockchain will calculate a hash value based on the data it contains (block number, pseudo-random number (nonce), and transaction data), and each block (except the first Outside the block) will record the hash value of the previous block to point to the previous block, thus realizing the concatenation of multiple blocks.

In the blockchain technology, the verification of a block is based on a majority decision, that is, when more than half of the nodes determine that the block is correct, the block can be verified as correct. Therefore, when a block of a node is tampered with, it can be known that the block is tampered by comparing the blocks of other nodes. general speaking, Blockchain technology has a strong anti-tampering ability. Unless more than half of the nodes are hacked and the transaction data of the block is tampered with at the same time, the tampered block will be verified as the wrong block.

In the embodiment of the present invention, after each node of the article publishing system based on blockchain technology obtains at least one piece of data, it will calculate the proof of work, and the first node that calculates the proof of work will announce it to other nodes. , Will calculate the hash value of the block, and throw the block to other nodes for verification. After other nodes verify the block, the blockchain will be updated to include the aforementioned verified block. The aforementioned at least one piece of data includes not only the title, content, author information, and token information of the article, but also command data. In this way, when the command data of a block in the blockchain includes a read article command, the user of the corresponding node can read the content of the corresponding article accordingly. In addition, when the command data of the block in the blockchain includes a masking command, users of all nodes will no longer be able to read the text of the article corresponding to the masking command.

In addition, in the embodiment of the present invention, the command data may also include a command to obtain a read key to decrypt the encrypted content of the article and/or a command to obtain a masking key to cover the content of the article. The reading key and the masking key are generated by the master key of the block corresponding to the article, and the master key of the block is generated based on all the data in the block. In addition, in the embodiment of the present invention, the read key can be designed to have a time limit, a usage limit, and a node limit.

The user can generate corresponding article data (including author information, title, text, and token information) through the article editing interface GUI31, and then the article data will be sent to other nodes connected to the user's node. Then, at regular intervals (for example, 3 seconds, but not as a limit), each node starts to calculate the proof of work, and the first node to obtain the proof of work (that is, the first to obtain the correct pseudo-random Count) will calculate the hash value based on the aforementioned data, block number, and pseudo-random number, and pack the aforementioned data, block number, pseudo-random number, calculated hash value and the hash value of the previous block into one Block. The packaged block will be sent to other nodes for verification. After more than half of the nodes verify that the block is correct, the entire blockchain will be updated to include the verified block. In this way, the article published by the user through the article editing interface GUI31 will be stored in each node. Even if several of the nodes fail, other nodes can still provide the article for the user to read.

If other users want to obtain this masked element, they need to trade through their client to obtain the masked element from the client that published the article, so that the user can read the masked element smoothly The text of the corresponding article data. On the other hand, the client that publishes the article can obtain the masking key, and according to the masking key, the client that publishes the article will no longer provide the masking element corresponding to the article data, thereby realizing the permanent masking effect of the content of the article data.

Please refer to FIG. 9, which is a schematic diagram of the composition of an article publishing system based on blockchain technology according to another embodiment of the present invention. The article publishing system 9 based on blockchain technology includes a storage node group 91, multiple clients (for example, a first client 92 and a second client 93), an interface server 94, an interface database 95 and a web server The storage node group 91 has multiple storage nodes directly or indirectly connected to each other. The storage node group 91 is directly or indirectly connected to the interface server 94 and the interface database 95, and the interface server 94 directly or indirectly It is connected to the first client 92, the second client 93, the database 95 and the web server 96. In this embodiment, preferably, the first client 92 and the second client 93 may be storage nodes in the storage node group 91, but the present invention is not limited thereto.

In this embodiment, at least one storage node in the storage node group 91 can be used to store the article data to be published by the user of the client (for example, the first client 92, but not limited to this). In addition, the first client 92 transmits the hash value of the article data to be published to the storage node group 91. Each node of the storage node group 91 stores the blockchain, and multiple blocks of the blockchain include not only transaction data but also hash table data. The hash table data records the relationship between the hash value of the article data and the address of the storage node storing the article data. The article data is usually stored in more than one storage node, and in this embodiment, the article data is addressed It is done by a complete addressing table constructed from hash table data.

Furthermore, in order to realize the shielding function, the first client 92 generates a shielding element of the article data before transmitting the article data to the storage node group 91. The content of the above article data will be automatically masked after the user enters it. Therefore, only the client (for example, the second client 93, but not limited by this) can obtain the article data and the masking element corresponding to this article data. Time, the second client 93 can read Read the text of the article data. The tokens required to obtain the shielded yuan can be set by the user of the first client 92 or automatically.

The mask element will be stored in the first client 92, the first client 92 will calculate the hash value of the article data and the transmission hash value of the mask element, and store the data of multiple blocks in the blockchain of the node group 91 The hash table data records the relationship between the hash value of the article data, the transmission hash value of the masking element, and the address of the first client 92. Then, after the hash value of the article data of the hash table data, the transmission hash value of the masking element and the address of the first client 92, the article data is stored in the storage node group 91, and then the hash table The data records the relationship between the hash value of the article data and the address of the storage node that stores the article data. In other words, the hash table data records the relationship between the hash value of the article data, the address of the storage node storing the article data, the transmission hash value of the masking element, and the address of the first client 92.

When the second client 93 wants to obtain the article data to be read, it can obtain the address of the storage node storing the article data and the address of the first client 92 storing the mask element by addressing through the hash table data. The second client 93 can perform a transaction to obtain the masking element from the first client 92. When the transaction data is also stored in the blockchain (that is, when the transaction is confirmed), the first client 92 will be requested to send the masking element to the second client 93, and the storage node storing the article data will send the article data to the second client User terminal 93. In this way, the second user terminal 93 can smoothly read the content of the article data. In addition, through the first client 92 disconnecting from the blockchain-based article publishing system 9, or through other means, the first client 92 will not be able to provide the masking element, so that the content of the corresponding article data will be permanently Obscured.

Preferably, a plurality of nodes in the storage node group 91 can obtain certain rewards by storing article data based on specific agreements and protocols. For example, the storage node group 91 can use the Interplanetary File System (IPFS) specification, but the present invention is not limited thereto.

In this embodiment, in order to accelerate the file access speed, the interface server 94 serves as the central server. The interface server 94 can serve as the storage node group 91 and the first client 92, the second client The bridge between. The interface server 94 can control part of the permissions of the first client 92 and the second client 93. For example, the first client 92 will not be able to provide the masking element corresponding to the article data, thereby realizing the function of permanently masking the content of the article data . The interface server 94 can further obtain the article data required by the second client 93 from the storage node group by connecting to the complete address table stored in the database 95 according to the request of the second client 93, and obtain the first The masking element of the corresponding article data stored in the client 92.

The interface database 95 is used to obtain the hash table data in the blockchain of the storage group node 91, and to generate and store a complete addressing table, thereby reducing the need for the second client 93 to address file data every time The time for the hash table data in the blockchain to construct a complete addressing table. The interface database 95 can update its complete addressing table synchronously every time the blockchain is updated. In addition, the web server 96 can provide web pages for the first client 92 and the second client 93 to provide the first client 92 with a user interface for publishing article data, and to provide the second client 93 with reading article data. User interface.

Please note here that the aforementioned interface server 94, interface database 95, and web server 96 can also be removed from the blockchain-based article publishing system 9 so that the blockchain-based article publishing system 9 can be A completely decentralized system, but the access performance and speed may slightly decrease. For example, when the aforementioned interface server 94, interface database 95, and web server 96 are removed, the blockchain-based article publishing system 9 can be similar to the existing interplanetary file system architecture, and the first A peer-to-peer network is formed between the client 92, the second client 93 and the storage node. Each time an article data is requested, the second client 93 or the storage node needs to verify the authenticity of the obtained hash table data and establish the correctness The complete addressing table.

Incidentally, the aforementioned token for obtaining the shielding yuan can be set to 0 to indicate that the article data is free for the user to read. The transaction information of multiple masked yuan can be used for statistics, so that the articles of the article data can be sorted according to the number of readings, or the articles of the article data can be sorted according to the cumulative reading consumption amount.

In addition, there are other ways to prevent the first client 92 from providing the masking element corresponding to the article data, in addition to disconnecting the first client 92 from the blockchain-based article publishing system. The first client 92 can pay a certain token to obtain the masking key, and use the masking key to control the interface server 94 to refuse any client to obtain the masking element of the first client 92; or, the first client 92 can pay A certain token obtains the shielding key, and uses the shielding key to encrypt the shielding element (note: the transmission hash value of the shielding element will change accordingly), so that the shielding element cannot be found smoothly.

When the second client wants to read the text Correspondingly, when the chapter data is released by the first client, the second client can know the address of the first client through the complete addressing table to obtain the masking element and obtain the article data from the storage node.

In step S111, the second client terminal initiates a transaction to the first client terminal, and the first client terminal will confirm the transaction information. After the first client terminal confirms the transaction information (that is, the transaction data has been successfully verified and written into the blockchain of the storage node group), in step S112, the first client terminal is based on the request of the second client terminal , And send the stored shielding element to the second client. In this way, the second user terminal can use the masking element to unmask the content of the article data, thereby smoothly reading the content of the article data.

Please refer to FIG. 12, which is a flowchart of an article publishing method based on blockchain technology used to cover the content of an article according to another embodiment of the present invention. In step S121, the first client can pay a certain token to obtain the shielding key, for example, after the transaction is completed, it is automatically generated by a specific software installed by the first client, or provided by the interface server. Then, in step S122, based on the masking key, the first user will no longer provide the masking element corresponding to the article data.

For example, in the case of an interface server, the interface server is instructed to prohibit the first client from providing the second client with the shielding element based on the shielding key, for example, in a firewall-like way, or directly The connection between the first client and it is broken; when there is no server connected, the first client encrypts the shielding element based on the shielding key, because the encrypted transmission hash value of the shielding element will change Therefore, the second client can no longer successfully obtain the masking element from the first client through the complete addressing table, so that the content of the article data will be permanently masked.
