Description

Technical Field

[0002] Blockchain technology is a technology that stores, verifies, transmits, and exchanges network data without relying on third parties, using its own distributed nodes. Nodes in a blockchain refer to computers running on the blockchain network. They connect to the blockchain network by running software clients and participate in its management. A blockchain is essentially a data structure that combines blocks in chronological order, with each block linked to the previous one via a hash, enabling information traceability. Except for the encryption of private information of the transacting parties, blockchain data is open to everyone; anyone can add their own information at any time using the same technical standards. Therefore, querying all information stored in a particular outcome based on the massive amount of data in a blockchain is not only time-consuming but also fails to provide a clear visual representation of the relationships between different stages of the same outcome and between different stages of the same outcome.

Other features of the invention will become readily apparent from the following description. Attached Figure Description

[0057] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0058] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0059] According to an embodiment of this application, a schematic diagram 100 of an application scenario for a blockchain-based method for protecting results throughout their entire lifecycle is provided. For example... Figure 1As shown, this application scenario includes user 110, first node 120, second node 130, third node 140, blockchain 150, and blockchain network 160. User 110 can upload stage information of the results through the first node 120, second node 130, and third node 140 to record the information of each stage of the results on the blockchain. The first node 120, second node 130, and third node 140 provide storage space and computing power support for the blockchain system. Blockchain 150 includes a first block, a second block, ..., an Nth block, each block storing corresponding information. Blockchain 150 is generated according to the chronological order of block generation. This blockchain 150 is stored in the first node 120, second node 130, and third node 140 through blockchain network 160. It is worth noting that the interactive communication between blockchain network 160 and the first node 120, second node 130, and third node 140 is called a transaction, and each node needs to jointly verify and record the information of the transaction. For example, the first node 120 needs to record the stage information on the blockchain 150. This process is a transaction of the first node 120 on the blockchain network 160. The blockchain network 160 sends the transaction corresponding to the first node to the second node 130 and the third node 140 for backup. It can be seen that the first node 120, the second node 130 and the third node 140 can all record or query the data of the entire life cycle of the result.

[0060] The deliverables include, but are not limited to, the creative ideas and digital assets generated by users during the creation process. The full lifecycle data of the deliverables includes, but is not limited to, the creation of the deliverables, data updates, changes in the ownership of the deliverables, records of data usage, and evaluation and auditing of the deliverables.

[0061] Those skilled in the art will understand that the above Figure 1 The example shown is merely one application scenario based on the present invention and is not intended to limit the scope of the invention.

[0062] Example 1

[0063] According to embodiments of this application, a method for protecting results throughout the entire blockchain lifecycle is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that presented here. Figure 2 As shown, the blockchain-based method for protecting the results throughout the entire lifecycle includes the following steps: S210, S220, and S230.

[0064] S210. Obtain the stage information of each result being uploaded to the blockchain, wherein the stage information includes information content and timestamp.

[0065] The outcome corresponds to one or more stages, which record the process of the transaction. A transaction chain consisting of multiple linked transactions corresponds to the outcome. For example... Figure 3 As shown, transaction chain A represents the full lifecycle data of result A, and transaction chain B represents the full lifecycle data of result B. Both transaction chains A and B are stored on the blockchain. Each transaction block on each transaction chain represents one of the stage information of the result. Each transaction block includes a transaction header and a transaction body, used to represent the timestamp and the information content of the stage information. The blockchain includes a block header and a block body. The block header includes a timestamp and a block height. The block body records the transaction blocks generated in each transaction chain at a certain time, or the block body records the stage information of the result generated at the corresponding time. Figure 3 The dashed lines indicate the positional index relationship of some transaction blocks in transaction chain A or transaction chain B within the block; the solid lines indicate the sequential connection relationship of each block in the blockchain, and the connection relationship of each transaction block in the transaction chain. For example, Figure 3 The transaction chain B[k+1] block is stored in the block corresponding to the “block i+3 hash”, where B[k+1] represents the (k+1)th transaction block of transaction chain B.

[0066] S220. According to the order of timestamps, the corresponding information content is stored in the blockchain in a chain, and there is a mapping relationship between the stage information of a single result according to the order of the corresponding timestamps.

[0067] Optionally, storing the corresponding information content in the blockchain in chronological order according to the timestamps includes: symmetrically encrypting the stage information to generate a symmetric key; encrypting the symmetric key a second time using the user's public key; and storing the information content of the stage information corresponding to the results in the blockchain in chronological order according to the timestamps, wherein a single block of the blockchain includes stage information corresponding to multiple results.

[0068] In a blockchain, all users can transact through the nodes at any time. Each node's ID is a key pair, including a public key and a private key, used to verify transactions and perform signature operations. Specifically, all transactions and block data in the blockchain are sent to all nodes. Each node verifies the legality of the block data and adds the legal data to its local blockchain database. For example, this embodiment of the invention provides a method for inter-node verification of transactions: at the current moment, a signature operation is performed based on the sender's private key corresponding to the fourth node to obtain the sender's signature, and the sender's signature is verified based on the sender's public key hash; a transaction hash is generated by packaging the transaction block including the stage information; the receiver corresponding to the fifth node performs a signature operation based on the sender's private key to obtain the receiver's signature; the receiver's signature is verified based on the receiver's public key hash. It should be noted that a concatenated signature hash is generated based on the private keys of each node and the hash of the receiver's public key. This concatenated signature hash is used to verify the accuracy of the consensus among the nodes in the blockchain and to ensure the security of data transmission. Figure 3 In a single block of a blockchain, the transaction blocks stored in the block body may belong to different transaction chains because, under a fixed timestamp, multiple achievements may generate stage information. Different blocks are hash-connected based on their generation time to form a blockchain. This blockchain contains transaction chains corresponding to each achievement. Within a single transaction chain, the block position of a transaction block is recorded by its block height in the information content. The transaction chain is obtained by hash-connecting the hash values ​​of each transaction block. By storing multiple different transaction chains in the blockchain, the stage information of a single achievement is stored in a chain-like manner on the blockchain.

[0069] Furthermore, the mapping relationship includes: encrypting the initial stage information of the single result according to a hash algorithm to generate an initial hash value of the result; calculating the hash value of the next stage information of the result based on the initial hash value; and linking the stage information of adjacent moments in the single result in the blockchain through the hash value, wherein the hash value corresponding to each stage information uniquely identifies the information content corresponding to the stage information in the result.

[0070] Optionally, the step of storing the corresponding information content in the blockchain includes: generating the information content based on the sequence number of the stage information, the contract type corresponding to the sequence number, and the validity of the stage information, and generating a corresponding smart contract based on the contract type; recording the update data of the stage information under different timestamps of the achievement by marking the validity of the stage information, wherein the update data includes adding new stage information, inserting new stage information, deleting or modifying the stage information, and referencing stage information of other achievements.

[0071] The smart contract is a computer program deployed on the blockchain that can automatically execute and be stored when predetermined conditions are met. The smart contract needs to be converted into directly executable chaincode based on the blockchain structure. This chaincode can convert the terms of the contract type into a sequence of instructions that can be directly written into the blockchain code line and set the trigger conditions for code execution. When the predetermined trigger conditions are met, the code runs automatically. Therefore, a corresponding smart contract is generated based on the contract type to be invoked according to the stage information and stored in a transaction block used to identify the stage information. When the smart contract in the transaction block is triggered, a transaction corresponding to the stage information can be recorded on the blockchain, and the transaction becomes effective, meaning the stage information is valid. The contract types include, but are not limited to, minting contracts, value-added contracts, rights confirmation contracts, signature contracts, and conversion contracts. The casting contract is used to create the result, corresponding to one transaction; the value-added contract is used to store the stage information after the creation of the result on the blockchain, corresponding to one transaction; the rights confirmation contract is used to store the generation and initial rights confirmation information of the result on the blockchain, corresponding to one transaction; the signature contract is used to store the certificate information of the result on the blockchain, corresponding to one transaction; the conversion contract is used to record the conversion information of the ownership and usage rights of the result, corresponding to one transaction. Figure 3 As shown, in transaction chain A, the transaction block corresponding to "transaction block j hash" records the stage information of project creation for result A. This transaction block calls the minting contract to generate a smart contract that can be automatically executed and stored by the blockchain, representing "project creation of result A." Similarly, the transaction block corresponding to "transaction block j+1 hash" records updated data information after the creation of result A. This transaction block calls the value-added contract to generate a smart contract that can be automatically executed and stored by the blockchain, representing "updated project data of result A." Furthermore, in transaction chain B, the transaction block corresponding to "transaction block k+2 hash" records that the stage information of result B references the stage information of result A, calls the value-added contract, and generates a smart contract that can be automatically executed and stored by the blockchain, representing "the reference relationship between result B and result A."

[0072] It should be noted that, Figure 3 The transaction blocks in transaction chain A or transaction chain B shown in the diagram call different contract types to generate corresponding smart contracts and store them in the transaction body. When the smart contract is triggered, the contract fulfills the transaction, and the stage information corresponding to the transaction is recorded on the blockchain.

[0073] Furthermore, the next stage information corresponding to the result is determined based on the union of the previous stage information and the updated data, and the validity of the invalid stage information in the union is set to zero; when the smart contract is triggered, the information content is stored in the blockchain, and the validity of the stage information is non-zero.

[0074] As an optional implementation, the transaction data is updated by adding the sequence number and validity of the stage information to the transaction body. On one hand, adding new stage information is implemented as follows: New stage information is added after the last transaction block in the current time step of the transaction chain; for example, assuming the sequence number of the stage information is set according to the rules of an arithmetic sequence, if the transaction chain at the current time includes stage information with sequence numbers 100, 200, and 300, then the new stage information sequence number is 400. On the other hand, inserting new stage information is implemented as follows: The sequence number of the new stage information is calculated, and the sequence number of the new stage information is among the sequence numbers of all stage information included in the current transaction chain; for example, if the transaction chain at the current time includes stage information with sequence numbers 100 and 200, the sequence number of the new stage information is calculated using a binary insertion algorithm, then the sequence number of the new stage information is 150.

[0075] As an alternative implementation, deleting or modifying the stage information does not involve clearing the stage information from the blockchain or replacing it with modified stage information. Instead, it operates on the stage information by changing the validity of the corresponding stage information. Specifically, if deleting a single stage information, a transaction block is added to set the validity of the single stage information to zero, indicating that the single stage information is invalid. If modifying a single stage information, firstly, a transaction block is added to set the validity of the single stage information to zero; secondly, a new stage information is inserted at the position of the stage information to be modified. Furthermore, there may be relationships between the transaction chains stored in the blockchain. These relationships are reflected in the transaction block using the hash value corresponding to the stage information sequence number, which is used to identify validity. Figure 3 As shown, transaction block k+2 of transaction chain B corresponding to result B references transaction block j+2 of transaction chain A corresponding to result A. This process demonstrates the reference relationship between transaction chain B and transaction chain A. The hash value of the referenced transaction block j+2 is recorded in the transaction body of transaction chain B, which is used to identify the stage information referencing other results, in a way that reflects the validity of the stage information sequence number. In short, the validity of the stage information includes setting it to zero, setting it to non-zero, and hash value. Setting it to non-zero indicates that the validity is marked as 1.

[0076] S230. Based on the mapping relationship, call and display part or all of the stage information of the single result in the blockchain.

[0077] Specifically, a state database is established based on the stage information of the individual achievement; the block is updated based on the stage information uploaded to the blockchain, and the update result is synchronized to the state database; some or all of the stage information of the individual achievement in the blockchain is called and displayed based on the state database and the mapping relationship.

[0078] The state database is created based on the corresponding transaction chain of the outcome. It is used to reorganize the transaction chain information based on a relational database, employing synchronization and deployment with the same information within the blockchain to achieve rapid querying of partial or complete stage information for a single outcome within the blockchain. The display of partial or complete stage information depends on the user's query request and the outcome's generation status. For example, if the outcome's generation status is still in the data update stage and has not yet reached the stages of outcome generation and initial rights confirmation, then based on the user's query request, only partial stage information corresponding to the current generation status of the outcome can be displayed, and not all stage information of the outcome after the current moment.

[0079] Optionally, the block where the stage information will be stored is determined based on the timestamp, and the block height of the block is recorded. The position of the stage information in the blockchain is then queried based on the block height.

[0080] This invention discloses a method for protecting research results throughout their entire lifecycle based on blockchain. The method includes: acquiring stage information of each research result uploaded to the blockchain, the stage information including information content and timestamps; storing the corresponding information content in a chain-like manner in the blockchain according to the chronological order of the timestamps, with a mapping relationship existing between the stage information of individual research results based on the chronological order of their corresponding timestamps; and retrieving and displaying some or all of the stage information of a single research result in the blockchain according to the mapping relationship. By employing the technical solution of this invention, the stage information corresponding to each individual research result is stored in a chain-like manner in the blockchain according to the mapping relationship, thus achieving protection of the research result's data throughout its entire lifecycle and enabling rapid querying of the stage information, improving query efficiency. Furthermore, by improving the blockchain data structure, every data update of the research result can be recorded, facilitating traceability.
