The hash value stored in the block chain has the characteristics of openness, transparency, non-falsification, convenience in tracing and the like, and is applied to numerous fields such as finance, public service, digital culture copyright, public welfare and the like. However, in practical applications, there are still many problems in the block chain, for example, in the field of cultural assets: after the whole network participation verification is carried out, the main chain technology of the block chain can only trace the hash value on the link, but cannot be modified, so that some error information of the block chain cannot be returned, and defects and burdens are caused to the verification of some cultural asset value fields. The main/side chain technique in the related art also has problems in practical applications, mainly focusing on the following three aspects:
1. all users on the main chain need to be verified before evaluating cultural assets, and the verification is performed by all persons, so that false nodes are caused, and resource waste is caused during verification;
2. a strict consensus system is arranged on a main chain, namely in cultural asset transaction, the main chain needs to process identity verification of a user, value verification of cultural asset, transaction verification and the like, and after the transaction is finished, a series of operations such as right confirmation and the like are required, so that the transaction process on the main chain is prolonged, and the transaction processing efficiency of the main chain is low;
3. compared with the main chain, the side chain is not completely decentralized, and the whole network consensus cannot be achieved, so that the side chain is easy to be utilized by illegal molecules when the side chain carries out cultural asset transaction, the safety coefficient of the transaction is low, and the large-scale application is difficult. In addition, since the main chain and the side chain are separated from each other, the transaction data ledgers of the main chain and the side chain cannot be effectively combined. Therefore, the application scenario of the side-chain technology in the related art is still limited to the authentication occasion.
Based on the above, the application provides a cultural asset transaction system and method based on a block chain, which are used for completing the verification of the cultural asset in a side chain and generating a first hash value; replacing the stored first hash value with the received second hash value after the cultural asset transaction is completed; completing culture asset transaction in the main chain according to the received first hash value to generate a second hash value; and replacing the stored first hash value with the second hash value. In the cultural asset transaction process, the bidirectional transmission channel is used for transmitting data between the main chain and the side chain, and bidirectional storage and synchronization of hash values between the main chain and the side chain are completed. Firstly, the embodiment of the application not only completes the verification of the cultural assets at the side chain, but also completes the evaluation of the cultural assets and expands the functions of the side chain. In addition, the embodiment of the application proposes to establish a bidirectional transmission channel to complete data synchronization of the main chain and the side chain, and the main chain does not need to be repeatedly verified when performing cultural asset transaction, so that the efficiency of the main chain for processing the hash value is greatly improved; the mode of bidirectional transmission also provides more implementation scenes for cultural asset transaction.
The embodiments of the present application will be further explained with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic diagram of a data flow direction provided by an embodiment of the present application, and the system 100 includes a side chain 110, a bidirectional transmission channel 120, and a main chain 130. In the design of the embodiment of the application, the whole process of cultural asset transaction is divided into two parts, namely verification and transaction. The verification part comprises verification of uplink users and uplink assets and evaluation of the uplink assets, when the verification is completed, the uplink users can complete transactions of cultural assets in a block chain, and work such as whole-network broadcasting is carried out after the transactions are completed. In the embodiment of the present application, the verification part is disposed at the side chain for processing, and when the side chain completes verification of the cultural asset information of the upper chain, a hash value which is successfully verified is generated, the system 100 provided by the present application synchronizes the hash value to the main chain by using a bidirectional transmission channel, and the main chain completes the operation of the transaction part. In short, in a cultural asset transaction, the asset transaction can be bought and sold in the main chain only by the side chain verification. After the main chain finishes the transaction, a new hash value for finishing the transaction is generated and transmitted to the side chain through the bidirectional transmission channel, and the existing hash value of the side chain is updated to finish the closed loop of the transaction. The side chain 110 is used to complete the cultural asset validation, generating a first hash value. The first hash value is a verification hash value generated by executing an intelligent contract of the side chain after the side chain completes the culture asset verification, and the first hash value forms a block, is serialized into a hash value flow and is transmitted to the main chain through a bidirectional transmission channel. The main chain 130 is used for completing the cultural asset transaction according to the received first hash value and generating a second hash value; the second hash value is a transaction hash value generated by executing an intelligent contract of the main chain after the main chain finishes the cultural asset transaction, the newly formed second hash value can replace the stored first hash value to represent that the cultural asset transaction is finished, the second hash value can form a block and is serialized into a hash value flow, and the hash value flow is transmitted to the side chain through the bidirectional transmission channel. And after the side chain receives the second hash value, the stored first hash value is replaced by the second hash value, and the closed loop of the transaction is completed. The bidirectional transmission channel 120 is used for data transmission between the main chain and the side chain, that is, a first hash value generated by the side chain is transmitted to the main chain, and a second hash value generated by the main chain is transmitted to the side chain, which helps to complete the hash value synchronization of the main chain and the side chain.
The cultural asset transaction system based on the block chain completes cultural asset verification in the side chain to generate a first hash value; replacing the stored first hash value with the received second hash value after the cultural asset transaction is completed; completing culture asset transaction in the main chain according to the received first hash value to generate a second hash value; and replacing the stored first hash value with the second hash value. In the cultural asset transaction process, the bidirectional transmission channel is used for transmitting data between the main chain and the side chain, and bidirectional storage and synchronization of the hash value between the main chain and the side chain are completed. Firstly, the embodiment of the application not only completes the verification of the cultural assets at the side chain, but also completes the evaluation of the cultural assets and expands the functions of the side chain. In addition, the embodiment of the application proposes that a bidirectional transmission channel is established to complete data synchronization of the main chain and the side chain, and the main chain does not need to be repeatedly verified when performing cultural asset transaction, so that the efficiency of the main chain for processing the hash value is greatly improved; the verification of cultural assets is completed at the side chain, the transaction right-confirming transfer and publicity of the hash value are completed at the main chain, the side chain is combined with the main chain through the bidirectional transmission channel, the advantages of the side chain and the main chain can be well combined, and the values of the side chain and the main chain in the block chain are exerted.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a block chain-based cultural asset transaction system according to an embodiment of the present application, and as shown in fig. 2, the side chain 110 includes an evaluation node 210, a verification node 220 and a first data node 230.
The evaluation node 210 is configured to evaluate the cultural asset in the blockchain by an authorized user, specifically, the authorized user in the blockchain evaluates the chained cultural asset on the side chain, the side chain notifies the user to evaluate the asset in a bidirectional notification manner, the user returns an evaluation opinion, and a value evaluation of the cultural asset is formed according to the opinions of the authorized users as many as possible in the side chain. In the side chain, the authorized culture participants can evaluate and price the value of the culture assets, the problem that the price of the culture assets is single or fluctuates greatly along with the price of the market wind direction is solved, the circulation of digital culture property rights is facilitated, and creators of the digital culture property rights are guaranteed. And because the data in the block chain is publicly traceable, the method is favorable for the publicization and decentralization of the cultural property value and is favorable for solving the problem of asymmetric information of the cultural property value in different regions.
The first data node 230 is a module that generates a hash value on a side chain. After the asset evaluation of the user is carried out by the evaluation node, the asset and the identity of the user are bound by the verification node, and the corresponding binding relationship between the asset information and the identity information is formed. Therefore, the hash values generated on the first data node are all good hash values, dirty hash values cannot occur, and reduction of error data in the block chain is facilitated. After the asset verification and the identity verification are finished, a first hash value is generated according to the binding relation between the asset and the identity, and the first hash value is serialized into a hash numerical flow to be transmitted to a main chain.
As shown in fig. 2, the bidirectional transmission channel 120 includes a logical node 240, an authority node 250, and a transmission node 260; when the main chain and the side chain need to transmit data through the bidirectional transmission channel, a logic node 240 is respectively established on the main chain and the side chain, and similarly, the authority node 250 and the transmission node 260 are also respectively established on the main chain and the side chain, and for more figuratively explaining the embodiment of the present application, the bidirectional transmission channel is separately drawn in fig. 2. The bidirectional transmission channel promotes message conversion and forwarding between hash values of different links through a message standardization and block chain transmission conversion protocol, simultaneously supports overtime of a request message, timeout reason analysis and message error processing when hash value transmission is carried out between a main chain and a side chain, finally realizes hash value sharing between the two links, and realizes generation of different hash value modules on the two links. During transmission, it is also necessary to verify whether the hash value already exists in the corresponding chain, if so, the hash value is not transmitted, and if not, the corresponding hash value needs to be bidirectionally transmitted.
The logical node 240 is mainly used to verify the communication packets between the main chain and the side chain, and to uniquely verify the hash values in the main chain and the side chain. That is, when the data of the side chain needs to be synchronized to the main chain, the communication message between the main chain and the side chain is judged first, and if the same message is generated before, the transaction is proved to have been initiated, and the transaction does not pass. If the communication message passes the verification, whether the hash value exists in the main chain needs to be judged so as to ensure the uniqueness of the transmitted hash value.
The authority node 250 is mainly used for adding authority and encryption processing to the data transmitted in the bidirectional transmission channel, or for verifying authority and decryption processing to the data transmitted in the bidirectional transmission channel. It should be noted that, since the embodiment of the present application designs a data channel for bidirectional transmission, it is possible that the main chain is a transmitting side and the side chain is a receiving side; it is also possible that the side chain is the transmitter and the main chain is the receiver. When the transmitting side transmits data, the public key encryption is carried out on the transmitted hash value message at the authority node, and the authority is added; when the receiving party receives data, the private key decryption is carried out on the received hash value at the authority node, the authority verification is required after the decryption is finished, and the double guarantee can ensure that hash value blocks are not written and leaked as far as possible. It will be appreciated that a public key and a private key are one of the encryption techniques, the public key being used to encrypt data and the private key being used to decrypt data encrypted by the public key. And finishing the safety protection of data flowing between the main chain and the side chain at the authority node.
During the data transmission process, situations such as instability of the transmission network may occur, and therefore the transmission node 260 is configured to maintain normal data transmission of the bidirectional transmission channel. And when the transmission network is unstable, carrying out breakpoint continuous transmission on the data of the bidirectional transmission channel. The breakpoint continuous transmission refers to that transmitted data is divided into a plurality of parts, each part is uploaded or downloaded by adopting one thread, and if a transmission network fault occurs, uncompleted parts can be continuously transmitted from the transmitted parts without uploading or downloading from the beginning, so that the time is saved, and the data transmission efficiency is improved. The transmission node supports data synchronous transmission, and when the data volume needing to be transmitted is smaller than a first threshold value, the data of the bidirectional transmission channel is synchronously transmitted in real time through the synchronous interface. In addition, the transmission node also supports asynchronous transmission, when the data volume needing to be transmitted is larger than a first threshold value, the asynchronous transmission can be carried out on the data of the bidirectional transmission channel, and hash value synchronous sharing is carried out in a hash value cache verification mode.
As shown in fig. 2, the backbone 130 includes a second data node 270, a trading node 280, and a disclosure node 290.
The second data node 270 is configured to store the first hash value, and when the side chain completes the cultural asset verification and transmits the first hash value to the main chain through the bidirectional transmission channel, the second data node on one side of the main chain is responsible for receiving and storing the first hash value. Because the first hash value is verified on the side chain, the verification on the main chain is not needed, and the use efficiency and the execution efficiency of the main chain are greatly improved. And after the cultural asset transaction is finished, executing an intelligent contract on one side of the main chain to generate a second hash value, and replacing the stored first hash value with the second hash value.
The transaction node 280 is used to complete a cultural asset transaction. In the transaction, the identity of both transaction parties is verified, and whether the hash values of the cultural assets needing to be transacted by both transaction parties are consistent or not is confirmed, namely the cultural assets needing to be transacted are confirmed. Then, the transaction parties are subjected to transaction consensus, and whether the transaction is carried out or not is confirmed by the transaction parties. If receiving the transaction refusing information of at least one transaction party, the transaction fails; similarly, if the transaction confirmation information of the two transaction parties is obtained, the authority of the hash value corresponding to the cultural asset needing to be transacted is transferred, and a transaction message is generated to inform the two transaction parties.
The public node 290 is used for broadcasting the whole network after the cultural asset transaction is completed, and informing all users on the main chain that the transaction is completed, so that the characteristic of transparent block chain disclosure is embodied.

The specific process of the main chain for completing the cultural asset transaction can refer to the expansion description of each node in the main chain, after the cultural asset transaction is completed, the main chain generates a second hash value, and the stored first hash value is replaced by the second hash value.
