Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
When the digital content transmission of the internet and the unprecedented prosperity and development of the application industry are carried out, the copyright infringement of the digital content is frequently carried out because no effective technical means exists for recording the transmission path of the digital content works. At present, the main infringement forms include content transportation, such as second stealing, code printing, picture-in-picture and the like, secondary creation, namely unauthorized editing of original materials, secondary creation of video materials and reference of the video materials (certain platforms or individuals split the works into a plurality of segments to provide for the public without permission of others), and the damaged digital content can include works such as literary works, short videos, movie and television shows, and also include works such as comprehensive sports music and animation.
In view of the above problems, one or more embodiments of the present specification provide a block chain-based content dissemination method, which manages the dissemination of copyrighted target digital content among different users.
The block chain or block chain described in one or more embodiments of the present specification may specifically refer to a P2P network system having a distributed data storage structure, where each node device achieves through a consensus mechanism, and the ledger data in the block chain is distributed within temporally consecutive "blocks", where the latter block may include a data digest of the former block, and achieves full backup of data of all or part of nodes according to a difference of the specific consensus mechanism (such as POW, POS, DPOS, or PBFT).
Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on.
Among them, the most decentralized is the public chain. The public chain is represented by bitcoin and ether house, and participants (also called nodes in the block chain) joining the public chain can read data records on the chain, participate in transactions, compete for accounting rights of new blocks, and the like. Moreover, each node can freely join or leave the network and perform related operations.
Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights specified by the organization. Briefly, a private chain may be a weakly centralized system with strict restrictions on nodes and a small number of nodes. This type of blockchain is more suitable for use within a particular establishment.
A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in a federation chain typically has a physical organization or organization corresponding to it; the nodes are authorized to join the network and form a benefit-related alliance, and block chain operation is maintained together.
It is contemplated that the embodiments provided herein can be implemented in any suitable type of blockchain.
The computing device may construct the data into a standard transaction (transaction) format supported by the blockchain, then issue the transaction to the blockchain, perform consensus processing on the received transaction by the node devices in the blockchain, and package the transaction into a block by the node devices serving as accounting nodes in the blockchain after the consensus is achieved, and perform persistent evidence storage in the blockchain.
Regardless of which consensus algorithm is adopted by the block chain, the accounting node can pack the received transaction to generate a latest block and send the latest block to other node devices for consensus verification. If the latest block is received by other node equipment and no problem is proved, the latest block can be added to the tail of the original block chain, so that the accounting process of the block chain is completed. The transactions contained in the block may also be performed during the process of the other nodes verifying the new block sent by the accounting node.
It should be noted that, each time a latest block is generated in the blockchain, the corresponding status of the executed transactions in the blockchain changes after the transaction in the latest block is executed. For example, in a block chain constructed by an account model, the account status of an external account or a smart contract account usually changes correspondingly with the execution of a transaction.
For example, when a "transfer transaction" is completed in a block, the balances of the transferring party account and the transferring party account associated with the "transfer transaction" (i.e., the field values of the Balance fields of these accounts) are usually changed.
For another example, the "intelligent contract invocation transaction" in the block is used to invoke an intelligent contract deployed on the blockchain, invoke the intelligent contract in the EVM corresponding to the node device to execute the "intelligent contract invocation transaction", and update the account status of the intelligent contract account in the account of the intelligent contract after the execution of the intelligent contract invocation transaction.
In practical applications, whether public, private, or alliance, it is possible to provide the functionality of a Smart contract (Smart contract). An intelligent contract on a blockchain is a contract on a blockchain that can be executed triggered by a transaction. An intelligent contract may be defined in the form of code.
Taking an Etherhouse as an example, a user is supported to create and call some complex logic in the Etherhouse network. The ethernet workshop is used as a programmable block chain, and the core of the ethernet workshop is an ethernet workshop virtual machine (EVM), and each ethernet workshop node can run the EVM. The EVM is a well-behaved virtual machine through which various complex logic can be implemented. The user issuing and invoking smart contracts in the etherhouse is running on the EVM. In fact, the EVM directly runs virtual machine code (virtual machine bytecode, hereinafter referred to as "bytecode"), so the intelligent contract deployed on the blockchain may be bytecode.
After Bob sends a Transaction (Transaction) containing information to create a smart contract to the ethernet network, each node can execute the Transaction in the EVM, as shown in fig. 1. The From field of the transaction in the figure is used for recording the address of the account initiating the creation of the intelligent contract, the contract code stored in the field value of the Data field of the transaction can be byte code, and the field value of the To field of the transaction is a null account. After the nodes reach the agreement through the consensus mechanism, the intelligent contract is successfully created, and the follow-up user can call the intelligent contract.
After the intelligent contract is established, a contract account corresponding to the intelligent contract appears on the block chain, and the block chain has a specific address; for example, "0 x68e12cf284 …" in each node in fig. 1 represents the address of the contract account created; the contract Code (Code) and account store (Storage) will be maintained in the account store for that contract account. The behavior of the intelligent contract is controlled by the contract code, while the account storage of the intelligent contract preserves the state of the contract. In other words, the intelligent contract causes a virtual account to be generated on the blockchain that contains the contract code and account storage.
As mentioned above, the Data field containing the transaction that created the intelligent contract may hold the byte code of the intelligent contract. A bytecode consists of a series of bytes, each of which can identify an operation. Based on the multiple considerations of development efficiency, readability and the like, a developer can select a high-level language to write intelligent contract codes instead of directly writing byte codes. For example, the high-level language may employ a language such as Solidity, Serpent, LLL, and the like. For intelligent contract code written in a high-level language, the intelligent contract code can be compiled by a compiler to generate byte codes which can be deployed on a blockchain.
Taking the Solidity language as an example, the contract code written by it is very similar to a Class (Class) in the object-oriented programming language, and various members including state variables, functions, function modifiers, events, etc. can be declared in one contract. A state variable is a value permanently stored in an account Storage (Storage) field of an intelligent contract to save the state of the contract.
As shown in FIG. 2, still taking the Etherhouse as an example, after Bob sends a transaction containing the information of the calling intelligent contract to the Etherhouse network, each node can execute the transaction in the EVM. The From field of the transaction in the figure is used for recording the address of the account initiating the intelligent contract calling, the To field is used for recording the address of the intelligent contract called, and the Data field of the transaction is used for recording the method and the parameters for calling the intelligent contract. After invoking the smart contract, the account status of the contract account may change. Subsequently, a client may check the account status of the contract account through the accessed block link points, for example, the account status may be stored in the Storage tree of the intelligent contract in the form of a Key-Value pair. The results of the execution of the transaction that invokes the smart contract, which may be in the form of a transaction receipt (receipt), are stored in the MPT receipt tree.
The intelligent contract can be independently executed at each node in the blockchain in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is executed, transaction certificates which cannot be tampered and cannot be lost are stored on the blockchain.
A schematic diagram of creating an intelligent contract and invoking the intelligent contract is shown in fig. 3. An intelligent contract is created in an Ethernet workshop and needs to be subjected to the processes of compiling the intelligent contract, changing the intelligent contract into byte codes, deploying the intelligent contract to a block chain and the like. The intelligent contract is called in the Ethernet workshop, a transaction pointing to the intelligent contract address is initiated, the EVM of each node can respectively execute the transaction, and the intelligent contract code is distributed and operated in the virtual machine of each node in the Ethernet workshop network.
For accounts in a blockchain, the account status of the account is usually maintained through a structure. When a transaction in a block is executed, the status of the account associated with the transaction in the block chain is also typically changed.
Taking etherhouses as an example, the structure of an account usually includes fields such as Balance, Nonce, Code and Storage. Wherein:
a Balance field for maintaining the current account Balance of the account;
a Nonce field for maintaining a number of transactions for the account; the counter is used for guaranteeing that each transaction can be processed only once, and replay attack is effectively avoided;
a Code field for maintaining a contract Code for the account; in practical applications, only the hash value of the contract Code is typically maintained in the Code field; thus, the Code field is also commonly referred to as the Codhash field.
A Storage field for maintaining the Storage contents of the account (default field value is null); for a contract account, a separate storage space is usually allocated to store the storage content of the contract account; this separate storage space is often referred to as the account storage of the contract account. The storage content of the contract account is usually constructed into a data structure of an MPT (Merkle Patricia Trie) tree and stored in the independent storage space; in which, the Storage content based on the contract account is constructed into an MPT tree, which is also commonly referred to as a Storage tree. Whereas the Storage field typically maintains only the root node of the Storage tree; thus, the Storage field is also commonly referred to as the Storage root field.
Wherein, for the external account, the field values of the Code field and the Storage field shown above are both null values.
For most blockchain models, Merkle trees are typically used; alternatively, the data is stored and maintained based on the data structure of the Merkle tree. Taking etherhouses as an example, the etherhouses use MPT tree (a Merkle tree variation) as a data organization form for organizing and managing important data such as account status, transaction information, and the like.
The Etherhouse designs three MPT trees, namely an MPT state tree, an MPT transaction tree and an MPT receipt tree, aiming at data needing to be stored and maintained in a block chain. In addition to the three MPT trees, there is actually a Storage tree constructed based on the Storage content of the contract account.
An MPT state tree, which is an MPT tree organized by account state data of all accounts in a blockchain; an MPT transaction tree, which is an MPT tree organized by transaction (transaction) data in a blockchain; the MPT receipt tree is organized into transaction (receipt) receipts corresponding to each transaction generated after the transactions in the block are executed. The hash values of the root nodes of the MPT state tree, the MPT transaction tree, and the MPT receipt tree shown above are eventually added to the block header of the corresponding block.
The MPT transaction tree and the MPT receipt tree correspond to the blocks, namely each block has the MPT transaction tree and the MPT receipt tree. For the MPT transaction tree, the MPT receipt tree and the MPT state tree which are organized, the MPT transaction tree, the MPT receipt tree and the MPT state tree are finally stored in a Key-Value type database (such as a levelDB) which adopts a multi-level data storage structure.
Based on the above-mentioned blockchain technology basis, as shown in fig. 4, an exemplary embodiment shown in the present specification provides a blockchain-based content dissemination method, on which an intelligent contract for dissemination management of copyrighted digital content is deployed. The forms of the digital content include, but are not limited to: written works, audio works, and video works.
The intelligent contract can be used by a provider (or a copyright side) of the digital content to develop, compile and deploy uplink codes based on specific rules for the propagation management of the digital content; at this time, the smart contract is used only for managing the digital content.
Or, a universal rule can be set for the propagation management of a plurality of digital contents of the same type or different types, and the development, compilation and deployment of the uplink of the intelligent contract codes are carried out based on the universal rule; at this time, the intelligent contract can be used for the dissemination management of various digital contents. A user entity (e.g., a rights management authority) having management rights to the smart contract may add or delete specific digital content objects to a list of management objects of the smart contract, or set corresponding unique dissemination management logic for different digital content.
Or, the user may directly extract the copyright confirmation operation on the digital content on the block chain, so as to add the target digital content to the management object of the intelligent contract deployed on the block chain after the copyright confirmation; the specific process can comprise the following steps:
acquiring a right confirming transaction initiated by a user and used for confirming the copyright of the digital content, wherein the right confirming transaction comprises a content abstract of the digital content;
invoking copyright validation logic of the intelligent contract declaration to determine whether the blockchain certifies a content digest containing the digital content; if not, generating a copyright certificate containing the content abstract of the digital content, issuing the content abstract of the digital content and the generated copyright certificate to the blockchain for storage, and storing the identifier corresponding to the digital content to a management object list of the intelligent contract, so that the intelligent contract can propagate and manage the digital content.
Based on the specific process of adding the digital content to the management object of the intelligent contract deployed in the block chain after the copyright is confirmed, the intelligent contract can perform network propagation management on the digital content with clear copyright information, and compared with the method for performing propagation management on the digital content without the copyright information verification, the method increases the effectiveness of the management content and improves the use efficiency of block chain resources.
Fig. 4 illustrates a block chain based content propagation method provided in an exemplary embodiment of the present specification. An intelligent contract for carrying out propagation management on digital content with copyright is deployed on the blockchain; the above-mentioned manner of deploying or editing the smart contract for copyrighted digital content may be as described in the above embodiments, and is not limited herein. The content dissemination method based on the block chain can comprise the following steps:
step 402, receiving a first transaction for triggering allocation of a virtual resource to a broadcaster of the digital content; wherein the first transaction may include dissemination data related to a dissemination action of the propagator for disseminating the digital content to a next propagator, or the first transaction may include a stored identification of the dissemination data. The storage identifier of the propagation data may be a hash value of the propagation data already stored in a blockchain, or may be a TxID of a blockchain transaction in which the propagation data is stored, or may be a storage identifier of the propagation data stored in a third-party storage system interfacing with the blockchain.
In order to further ensure the real validity of the transmission data, the third-party storage system should be a legal storage system for obtaining the block chain authentication, for example, may be another block chain having a cross-chain reference relationship with the block chain, or may be a centralized business system interfacing with the block chain, for example, a sharing platform of the digital content; the centralized service system is used for collecting the transmission data of the digital content among the users.
The propagation behavior may include: and enabling the next-level propagator to obtain the digital content, or obtain the description information of the digital content, or obtain the behavior of a purchase channel of the digital content based on the operations of sharing, recommending, evaluating and the like of the propagator on the digital content. Accordingly, the dissemination data may include dissemination record data provided by the propagator or provided by a digital content server (e.g., a server corresponding to a literary composition website, a video sharing platform, a network music platform, etc.) serving the dissemination activity, and describing that the propagator disseminates the digital content to the next propagator.
The identity of the user of the sender of the first transaction is not limited in this embodiment, and for example, the broadcaster may serve as a client of the block chain to pick up the first transaction to the smart contract, or the digital content server that performs the broadcast may pick up the first transaction to the smart contract through a node device of the block chain that the broadcaster interfaces with.
Step 404, in response to the first transaction, invoking a checking logic in the intelligent contract, acquiring propagation data related to propagation behavior of the propagator for propagating the digital content to a next propagator, and performing authenticity checking on the propagation data based on the propagation data.
Based on different contents contained in the first transaction, the node device may invoke the intelligent contract and obtain the propagation data in different ways. When the first transaction contains the propagation data, the node equipment can directly acquire the propagation data from the first transaction; when the first transaction includes the identification information of the propagation data, the node device may acquire the propagation data from the blockchain or a third-party storage system docked with the blockchain based on the identification information. The present embodiment does not limit the specific content of the check logic in the intelligent contract. In an illustrated embodiment, the node device of the blockchain executes the above-mentioned verification logic, and the process of performing the authenticity verification on the propagation data may include verifying a digital signature made by a user with the evidence-based right of propagation behavior, which is included in the first transaction; and if the digital signature passes the verification, the authenticity check on the propagation data passes. The user with the transmission behavior witness right may include an operation mechanism of the digital content sharing platform according to the foregoing embodiment, or another user authorized by the verification logic of the intelligent contract.
In a further illustrated embodiment, when the first transaction includes a storage identifier (such as TxID or hash value corresponding to the propagation data) of the propagation data stored in the blockchain, the node device of the blockchain executing the above-mentioned checking logic may perform a process of performing authenticity check on the propagation data based on the propagation data, which may include: verifying whether the block chain stores the propagation data corresponding to the storage identification; if so, the authenticity check for the propagated data passes.
In a further illustrated embodiment, when the first transaction includes a storage identifier of the propagation data stored in a third-party storage system, the performing, by a node device of a blockchain, the above-described verification logic, and performing an authenticity verification on the propagation data based on the propagation data may include: initiating a verification event to the third-party storage system, wherein the verification event is used for informing the third-party storage system to verify whether the propagation data corresponding to the storage identification is stored; and acquiring a response message of the third storage system, and if the response message indicates that the third storage system stores the propagation data corresponding to the storage identifier, checking the authenticity of the propagation data.
In the implementation process of the check logic, the event-response flow between the node device and the third-party storage system can be implemented through a cross-link relay interface or a prediction machine which is arranged in the block chain and is in butt joint with the third-party storage system.
Step 406, if the authenticity check on the propagation data passes, further invoking an allocation logic in the intelligent contract to allocate virtual resources to the propagator; wherein the digital content generates copyright usage revenue after the Nth spreading caused by the spreading behavior; the virtual resource is value-anchored with at least a portion of the copyright usage revenue; and N is a positive integer.
The specific process of generating the copyright revenue may include that a user of the digital content sharing platform purchases the digital content for further acquiring all the content of the digital content after receiving the description information of the digital content; the method may further include, after obtaining the digital content, paying a copyright usage fee to a copyright holder of the digital content for further performing operations such as copying, distribution, or adaptation of the digital content, and the like, which is not limited herein. And the node equipment of the block chain calls the allocation logic for executing the intelligent contract, and the virtual resource allocated to the propagator is subjected to value anchoring with the copyright revenue generated after the N-th propagation caused by the propagation behavior of the digital content. Thus, it is expected that when a propagator obtains a corresponding virtual resource based on its propagation behavior, the virtual resource may not have been anchored with real value yet; the propagator obtains the virtual resource which can be anchored with real value after the N propagation caused by the propagation behavior generates the copyright use profit.
Fig. 5 illustrates a route pattern in which digital content is distributed from a distributor 501 to a subordinate user. If the digital content generates the profit of the copyright use by the user 555 after the digital content is shared and propagated to the user 555 by the propagator 543, one or more of the propagators (the propagators 501, the propagators 524, the propagators 535, and 543) on the propagation path (the propagators 512 and 524 of the propagators 501 and 543) causing the profit of the copyright use (the propagators 512 and 524 of the propagators 501) can be held, and the virtual resources obtained based on the propagation behaviors can be value-anchored with at least part of the profit of the copyright use generated by the purchasing behavior of the user 555.
It should be noted that the user 555 may also be used as a propagator to perform next-level propagation on the digital content, and obtain a corresponding virtual resource based on the processes of steps 402 to 406 performed by the node device in the above embodiment, so as to perform value anchoring with at least part of the copyright usage revenue generated after the nth propagation caused by the propagation behavior of the user 555.
When N =0, the propagator directly generates the copyright use benefit after the propagation behavior, and the next stage propagator in the propagation behavior pays the copyright use fee based on the copyright use behavior, thereby generating the copyright use benefit.
Since the propagator obtains virtual resources based on the propagator's propagation of the digital content, and the virtual resources obtained by the propagator's propagation behavior can have real value in generating revenue for copyright use, in an illustrated embodiment, the virtual resources obtained by the propagator's allocation in step 406 can be regarded as a virtual resource account, and the specific virtual resource value held by the virtual resource account can be specifically calculated and assigned based on the revenue allocation logic agreed by the intelligent contracts described in the following steps 408 to 410 in generating revenue for copyright use; therefore, the virtual resource value assigned and held by the virtual resource account when the copyright use income is generated can directly have a value anchoring relation with the real asset.
In yet another embodiment, the virtual resource allocated by the propagator in step 406 may be a preset first number of virtual resources, for example, m units of virtual resources may be obtained based on the propagator's propagation behavior of the digital content; however, the value anchoring relationship between the virtual resource with the preset value and the real asset, that is, the value conversion relationship between the virtual resource and the copyright revenue (for example, the rmb) per unit (which may be regarded as the unit price of the virtual resource), may be determined based on the revenue distribution logic of the intelligent contract when the revenue of copyright use is generated.
The virtual resource or the virtual resource account allocated to the propagator may be stored in the account storage space of the intelligent contract in correspondence with the user identifier of the propagator; alternatively, the information may be stored in the block chain account of the broadcaster and held by the block chain account of the broadcaster. When a predetermined amount of virtual resources are allocated to the broadcaster in step 406, the virtual resources may represent an on-chain balance of the blockchain account of the broadcaster.
Step 408, receiving a second transaction for triggering distribution of copyright usage revenue to the propagator; wherein the second transaction includes an amount of copyright usage revenue generated by the digital content after the Nth dissemination;
step 410, in response to the second transaction, invoking benefit distribution logic in the intelligent contract, obtaining a corresponding propagation path of the digital content after the N times of propagation, and performing value anchoring on at least part of the copyright usage benefit and virtual resources distributed to the multi-stage propagators in the propagation path.
The node device calls the intelligent contract, and can establish the propagation path step by step along with the occurrence of each stage of propagation behavior in the account storage space of the intelligent contract based on the user identification of the propagator which propagates the digital content and the user identification of the next stage of propagator contained in the propagation data and referring to the time stamp of the occurrence of the propagation behavior. In this way, in response to the second transaction, the node device may directly obtain, from the account storage space of the smart contract, a propagation path from the propagator to the nth stage propagator corresponding to the nth propagation.
Or, the node device may also invoke the intelligent contract, respond to the second transaction, acquire propagation data stored in the blockchain and corresponding to each of N propagations of the digital content, where the propagation data includes a timestamp corresponding to a propagated time of the digital content, and generate a propagation path corresponding to the digital content according to the obtained propagation data in the order of the timestamps; further, the generated propagation path may be issued to the blockchain for storage.
In an illustrated embodiment, when the virtual resource obtained by the propagator based on its own propagation behavior is regarded as a virtual resource account, the node device performs a process of anchoring at least part of the copyright usage benefit and the value of the virtual resource obtained by the multi-stage propagator in the propagation path, that is, a process of allocating a virtual resource amount (that is, the virtual resource account assignment) to the virtual resource account.
As shown in fig. 5, assuming that the digital content is X-ary based on the revenue of copyright usage generated by the user 555 purchasing the digital content after the nth distribution, the node device invokes the revenue allocation logic of the smart contract to allocate, in response to the second transaction, the amount of virtual resources having a value anchor relationship with at least part of the X-ary, the Y-ary, to one or more of the distribution paths (distributor 501 distributor 512 distributor 524 distributor 535 distributor 543):
m1+m2+……mN=Y/d;
where d is the unit price per virtual resource, m1、m2、……mNThe number of virtual resources allocated in the virtual resource account held by the propagator.
The present embodiment does not limit the specific assignment rule for the virtual resource account held by the propagator in the propagation path. For example, the purchase behavior of the user 555 or the generation event of the copyright usage profit is directly caused by the propagator 543 propagating the digital content to the user 555, so that the propagator 543 can obtain more profit than other propagators on the propagation path, and therefore, the intelligent contract may be provided with a virtual resource allocation assignment rule that sequentially decreases from the propagator 543 to the propagator 501 in the propagation path; or, only assigning virtual resources to the propagators in a preset stage number L from the user 555, and when L =3, assigning virtual resources obtained by the propagators 543, 535, 524.
The process of assigning a value to the virtual resource account may be regarded as a process of allocating a corresponding amount of virtual resources to the virtual resource account obtained by the propagator. Since the assignment process is performed based on the real asset of the copyright usage profit of the digital content, and the real asset amount (i.e., the unit price of the virtual resource) corresponding to each virtual resource is determined in the process, the specific virtual resource amount can be allocated to the virtual resource accounts held by different propagators according to the determined unit price of the virtual resource.
Since the assignment process usually gives the propagator directly triggering the copyright usage profit generation event of the digital content (for example, the propagator 543 in fig. 5) or the propagator in several propagation levels close to the propagator directly triggering the copyright usage profit generation event (for example, only assigning values to virtual resource accounts held by the propagators 543, 535, 524 in fig. 5), the incentive of such profit assignment logic to the initial propagator of the digital content or the propagators in multiple propagation levels close to the initial propagator (for example, the propagators 501, 512 in fig. 5) is insufficient, and the participation will of some users is reduced.
Therefore, in response to the first transaction, the node device may allocate, in addition to allocating the corresponding virtual resource account to the propagator, a predetermined number of virtual resource rewards to the virtual resource accounts already allocated by the multi-level propagator initiating the propagation behavior based on the propagation of the digital content (i.e., increase the value corresponding to the virtual resource accounts held by the multi-level propagator). The multi-stage propagator initiating the propagation behavior may include, starting from a propagation source of the digital content, delivering the digital content to other propagators of the propagator stage by stage, and thus may include a parent of the propagator, a parent of the parent, etc., in sequence up to the source.
Thus, as shown in FIG. 5, when digital content is propagated by propagator 501, propagator 512, propagator 524, propagator 535, propagator 543, user 555, according to propagation path: based on each dissemination of the digital content from the propagator 512, the virtual resource account held by the propagator 501 can obtain a preset number of virtual resource rewards; based on each dissemination of the digital content from the propagator 524, the virtual resource accounts held by the propagator 512 can each obtain a preset number of virtual resources as rewards; by analogy, each propagator may receive a corresponding amount of virtual resource rewards based on each propagation of the digital content at its lower level. In this way, the propagators having higher propagation levels, that is, the users who join the digital content propagation first, gradually accumulate more virtual resources, and in the propagation path shown in fig. 5, the user 501 can obtain more virtual resources as a reward than the user 543 based on the digital content propagation. Even if the copyright use profit of the digital content is generated based on the purchase behavior of the user 555, the number of the virtual resources anchored by the propagator 543 is larger than that of the propagator 501, and the propagator 501 can obtain more virtual resources accumulated based on the propagation behavior; the distribution mode balances the distribution of the copyright use income of the digital content among different levels of users, so that the users can have various channels for obtaining the reward, and the users are encouraged to participate in the dissemination of the digital content.
Since the amount of the virtual resources in the virtual resource account has an anchoring relationship with the real asset value, the value actually anchored by the virtual resources allocated by the node device to the multi-level propagator inducing the propagation behavior may be the copyright usage profit of the digital content which is pre-paid in advance, or the actual amount divided from the income of the user for encouraging the user to propagate the digital content.
In another illustrated embodiment, when the virtual resource allocated to the propagator in step 406 is a preset first amount of virtual resource, the process of the node device performing value anchoring on at least part of the copyright usage profit and the virtual resource allocated to the multi-stage propagator in the propagation path in step 410 may include: determining a revenue unit amount anchored to a unit amount of the virtual resource value based on at least a part of the copyright usage revenue, the revenue unit amount Y-gram, and a total amount of virtual resources held by the multi-stage propagator assigned to the propagation path (note that the total amount of virtual resources obtained by the multi-stage propagator in the propagation path includes not only the first amount of virtual resources assigned to each stage propagator based on the propagation behavior of each stage propagator, but also the amount of virtual resources obtained as a reward by calling the smart contract by the node device); and issuing the calculated unit income amount and the value anchoring relation of the unit quantity of the virtual resources to the block chain for evidence storage.
Firstly, determining a list of propagators which can obtain revenue in the propagation path, for example, performing value anchoring of virtual resources and revenue amount for all propagators in the propagation path, or performing value anchoring of virtual resources and revenue amount for only propagators within a preset number L from a user 555; obtaining the quantity of the virtual resources obtained by each propagator in the propagator list, and thus calculating the unit income amount and the value anchoring relation of the virtual resources of the unit quantity, namely the amount of income amount (or unit price of the virtual resources) that each virtual resource can exchange.
The unit price of each virtual resource held by different propagators included in the list of propagators that can obtain profit may be the same or different. When the unit prices of the virtual resources held by different levels of propagators are the same, assuming that the total number of the virtual resources obtained by the propagators in the propagator list capable of obtaining the profit is M, the unit price d = Y/M of each virtual resource.
When the unit price of the virtual resource held by the propagators in different levels is different, special unit price rules can be set for the propagators in different levels. For example, the unit price of the virtual resource held by the first-level propagator is d1= p + d, the unit price of the virtual resource held by the second-stage propagator is d2If = p +2d, … …, the unit price of the virtual resource held by the nth level propagator is dNAnd = p + Nd, p is a base unit value of the virtual resource set by the smart contract, and m1 and m2 … … mN are the number of virtual resources held by different levels of propagators included in the list of propagators capable of obtaining revenue.
In this case based on (p + d) m1+(p+2d)m2+……+(P+Nd)mND can be calculated, so as to determine the unit price of the virtual resource held by each stage of propagator1=p+d, d2=p+2d,……, dN=p+Nd。
In the above-described process of allocating virtual resources to virtual resource accounts held by a plurality of propagators in a propagation path based on the profit of copyright use, the closer to the propagator that generates the profit of copyright use event, the greater the profit value anchored by each virtual resource, for example, the higher the price per unit of virtual resources held by the propagator 543 than the price per unit of virtual resources held by the propagator 501. In order to encourage more users to participate in the dissemination of the digital content, the step 406 of invoking the allocation logic in the smart contract may allocate a predetermined second number of virtual resource rewards to the multi-level propagators inducing the dissemination in addition to the predetermined first number of virtual resources to the propagators in allocating the virtual resources to the propagators. The multi-stage propagator initiating the propagation behavior may include, starting from a propagation source of the digital content, delivering the digital content to other propagators of the propagator stage by stage, and thus may include a parent of the propagator, a parent of the parent, etc., in sequence up to the source.
Thus, as shown in FIG. 5, when digital content is propagated by propagator 501, propagator 512, propagator 524, propagator 535, propagator 543, user 555, according to propagation path: the propagator 501 may receive a second number of virtual resource rewards each time based on the invocation of the smart contract by each propagation behavior of the digital content from the propagator 512; the propagator 512 can obtain a second amount of virtual resources each time based on the invocation of the smart contract by the propagator 524 of the digital content for each propagation behavior; by analogy, each distributor can obtain a corresponding amount of virtual resource rewards based on the sum of the number of times the digital content is distributed at its subordinate level. As described above, the propagators having higher propagation levels gradually accumulate more virtual resources, and in the propagation path shown in fig. 5, the user 501 can obtain more virtual resources as a reward than the user 543 based on the propagation of the digital content. Even if revenue of copyright use of the digital content is generated based on the purchasing behavior of the user 555, the unit price of the virtual resource held by the propagator 543 is higher than that of the propagator 501, the propagator 501 can obtain more amount of the virtual resource accumulated based on the propagating behavior, so that in the revenue allocation described in step 410, the matching revenue amount is anchored based on the unit price and amount of the virtual resource.
Alternatively, the smart contract may further provide a separate reward logic to encourage the user to propagate the digital content, in this embodiment, the blockchain-based content propagation method further includes:
receiving a call transaction for triggering allocation of reward resources to the propagator;
responding to the calling transaction, calling reward logic in the intelligent contract, and respectively calculating the total number of times of propagation caused by each level of propagator in the propagation path to the digital content; and distributing virtual resources serving as propagation rewards to the propagators of which the sum of the propagation times is greater than a preset threshold value.
The call transaction for triggering the allocation of the reward may be triggered by the manager of the smart contract at predetermined intervals.
The distribution mode balances the distribution of the copyright use income of the digital content among users and encourages the users to participate in the dissemination of the digital content.
The propagator can periodically lift the cashing operation of the acquired virtual resource quantity based on the self requirement. The process of redemption may include:
step 412, the node device of the block chain acquires a third transaction for triggering virtual resource conversion, where the third transaction includes a target number of the virtual resources to be converted, which is specified by the conversion party. The redeeming party may include the propagator user, and may also include other users who receive the virtual resource account of the propagator, or other users who receive a number of virtual resources included in the virtual resource account of the propagator.
Step 414, responding to the third transaction, invoking the smart contract, executing the virtual resource exchange logic declared by the smart contract, calculating an exchange amount based on the target amount of the virtual resource to be exchanged, and generating a payment event corresponding to the exchange amount, so that a payment system docked with the blockchain responds to the payment event, and performing exchange payment processing on a fund account corresponding to the exchanger based on the exchange amount.
When the virtual resource allocated to the propagator in step 406 is a virtual resource account, the unit price (i.e., the cash amount corresponding to the virtual resource) of the virtual resource anchored in the virtual resource account in step 410 is determined in the block chain, and the intelligent contract can directly calculate the redemption amount corresponding to the target amount of the virtual resource to be redeemed.
When the virtual resources allocated to the propagator in step 406 are virtual resources of a preset number, since unit prices of the virtual resources held by the propagators at different propagation levels may be different, the calculating of the redemption amount based on the target number of the virtual resources to be redeemed may include obtaining a unit amount of the virtual resources to be redeemed and a unit amount of income obtained after anchoring the copyright usage income value, and calculating the redemption amount based on the unit amount of income and the target number of the virtual resources to be redeemed.
Step 416, after receiving the payment certificate corresponding to the payment event submitted by the payment system, further invoking a virtual resource updating logic of the intelligent contract statement, and deleting the target number of virtual resources held by the redemption party; or, the target number of virtual resources held by the redeeming party is marked as redeemed.
When the payment system interfaces with the blockchain, the payment system can submit the payment credential to the blockchain in a transactional manner. When the payment system is not docked with the blockchain, the payment voucher can initiate payment notification to the payment system by a predicting machine docked with the blockchain system, and obtain the payment voucher submitted by the payment system, and at this time, the predicting machine can respond to the payment event and send the payment voucher to the intelligent contract based on an event response mechanism of the intelligent contract.
Based on the content propagation method based on the block chain provided by each embodiment, the virtual resources allocated to the propagator and the copyright use income of the digital content are subjected to value anchoring, users are encouraged to join in the propagation of the digital content, and a propagation path for the digital content propagation is established on the block chain, so that the propagation and the copyright use of the digital content are more standardized, and the probability of the digital content being used by infringement and piracy caused in the current situation that the digital content is propagated without recording can be effectively reduced.
