Background
The existing block chain network can be roughly divided into three types, namely a public chain, a alliance chain and a private chain, according to the node scale, the consensus mechanism and the operation scene. Various types of blockchain networks, which are used to generate, store, and run a separate blockchain, can process corresponding transactions and store transaction data into blocks. The blockchain network based on each blockchain is participated by a plurality of nodes, and the nodes are provided with data required by a consensus mechanism, an intelligent contract, an incentive mechanism, an encryption algorithm and the like required by the operation blockchain technology. Typically, nodes are required to provide computing power for proper functioning of the blockchain, and thus nodes are rewarded for participation in blockchain processing and storage by issuing and dispensing digital currency.

With the rapid development of blockchain technology, the application scenario of blockchain technology has not been limited to digital currency transactions, for example, people are not satisfied with running transactions in only one independent blockchain, or are no longer satisfied with running old transactions using only one intrinsic mode blockchain, resulting in the need to continuously retrofit transaction modes. Therefore, the above block chain type cannot be adapted to the requirements of various scenes.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of an implementation method of a blockchain network according to an embodiment of the present invention, where the implementation method is applicable to a situation where a base-chain network node processes parallel-chain related data, and the implementation method may be implemented by an implementation apparatus of a blockchain network, where the implementation apparatus may be implemented by software and/or hardware, and may be generally integrated in a computer device that assumes functions of the blockchain network node, and the blockchain network node may be a base-chain network node, specifically, a block generation node having block processing authority in the base-chain network, or may be any other network node. As shown in fig. 1, the method includes the operations of:
s110, acquiring a basic chain transaction request sent by a network node, wherein the network node participates in a basic chain network and a parallel chain network at the same time, and the basic chain transaction request comprises data of a parallel chain.
Wherein, the basic chain is a block chain, which can be used to establish the connection between various independent block chains. The basic chain can be associated with the corresponding parallel chain and is used for assisting in creating the parallel chain, managing the parallel chain and assisting in data exchange of the parallel chain. For example, the underlying chain can be used to establish a link between existing blockchains that are independent of each other, such that data interactions in a blockchain are no longer limited to a single blockchain, such that the range of value flow is no longer limited to a single blockchain. That is, the base chain may manage and supervise the operational parameters throughout the blockchain network.
Parallel chains are also a kind of block chains, which are a relative concept to the underlying chains. Parallel chains have all the attributes of a generic blockchain, while potentially being built, managed, and data exchanged on a basic chain basis. The parallel chain can be derived from the basic chain, or can have the equivalent status and function with the basic chain, and mutually assist the establishment, management and data exchange. There may be one or more parallel chains. And optionally, the multiple parallel chains are independent from each other and do not affect each other, or two parallel chains may be in a relationship between a basic chain and a parallel chain.
Generally, the basic chain is established and operated before the parallel chain, and the basic chain has higher public confidence and calling force and is more well accepted in value. The nodes of the parallel chain can utilize the public trust and summons of the nodes of the basic chain to serve them with the nodes willing to provide the computing power.
The base chain and the parallel chain may form a hyperchain network. In a hyperchain network, the base chain may also be one or more. It should be noted that there is an overlapping relationship between all nodes participating in the base chain and all nodes participating in the parallel chain. That is, at least some of the nodes participating in the parallel chain are the same network nodes as at least some of the nodes participating in the underlying chain. In these overlapping network nodes, all the data of the block chains in which they participate are deployed, that is, the deployment data of both the basic chain and the parallel chain are stored, and the blocks of both the basic chain and the parallel chain are also stored. Because the data of different block chains are deployed at the same time, the network node can generate transaction requests of different block chains and can locally query the transaction data in different block chains, thereby facilitating the cross-chain transaction processing.
It should be further noted that the basic chain and the parallel chain may be activated by using the same or different types of digital currencies, and the accounts of the network nodes of the basic chain and the parallel chain, which are used for storing digital currencies, may store a plurality of different types of digital currencies at the same time, and the digital currencies in each block chain may interact with the accounts, such as transferring digital currencies in or out. The motivation of the blockchain is not limited to digital currency, but may be other elements managed by the account number.
The account can be managed through an asymmetric key pair, the public key is an account address, and the private key is saved by an account owner. The basic chain transaction request may be a transaction request or other pending transaction request that occurs within a period of time in the basic chain network. The parallel chain data included in the base chain transaction request may include, but is not limited to, deployment data for the parallel chain, transaction requests, digital currency in a smart contract or account number, and the like.
In the embodiment of the invention, two different types of blockchains, namely a basic chain and a parallel chain, can exist in the blockchain network at the same time. The parallel chain may be a block chain derived from a base chain, and the base chain may provide cross-chain services for the parallel chain. The nodes participating in the parallel chain may be some or all of the nodes in the base chain, wherein the nodes participating in the parallel chain may autonomously choose whether to participate in the running of the parallel chain before participating in the parallel chain network.
In an optional embodiment of the present invention, the network node stores both the base chain and the parallel chain, and stores deployment data of the base chain and the parallel chain.
The deployment data may be data corresponding to a data layer, a network layer, a consensus layer, an incentive layer, a contract layer and an application layer in a blockchain, such as data blocks, time stamps, a propagation mechanism, a verification mechanism, an issuance mechanism, an algorithm mechanism, an intelligent contract or programmable currency.
In the embodiment of the present invention, the network node may be a node capable of processing the transaction requests in the basic chain network and the parallel chain network at the same time, so that the deployment data corresponding to the block chain network and the parallel chain network can be stored at the same time, and the block chain transaction data of the basic chain and the parallel chain can be stored at the same time.
And S120, processing the basic chain transaction request, and storing the basic chain transaction data into a block of the basic chain.
The basic chain transaction data may be initiated by a basic chain network node and needs to be added to the data stored in the block after being processed by the block generation node, where the processing may include information conversion, format adjustment, or code execution, and is performed according to the specific situation of the transaction data. The block generation node may be a node having block processing authority in the block chain network. For example, conventional transaction request data is typically a type of transaction data. Different application scenarios of the blockchain can generate different transaction data to be processed. In the same application scenario, the transaction data sent by the nodes may be the same or different.
In the embodiment of the present invention, after receiving the basic chain transaction request, the block generation node in the basic chain network may process the transaction request according to the specific situation of the transaction request to generate corresponding basic chain transaction data, and store the basic chain transaction data in the block of the basic chain.
In an optional embodiment of the present invention, while or after processing the basic chain transaction request and storing the basic chain transaction data in the block of the basic chain, the method may further include: and generating a parallel chain transaction request according to the basic chain transaction request and the locally stored parallel chain deployment data, and sending the parallel chain transaction request in the parallel chain network.
The parallel chain transaction request is a transaction request which can be transmitted in a parallel chain network and processed by a parallel chain node, and can be a transaction request or other pending transaction requests.
In the embodiment of the present invention, when the basic chain network node acquires the basic chain transaction data, a parallel chain transaction request may also be generated according to the data of the parallel chain included in the basic chain transaction request, and the generated parallel chain transaction request is sent in the parallel chain network. That is, the base chain may enable data interaction between the base chain and the parallel chain by sending a parallel chain transaction request to the parallel chain. For example, the base chain informs the parallel chain of the transaction to be processed or the data to be queried, etc. through the parallel chain transaction request. A block generation node in the parallel chain network may receive the parallel chain transaction request, process it to generate parallel chain transaction data, and store the parallel chain transaction data into the blocks of the parallel chain.
In an optional embodiment of the present invention, while or after processing the basic chain transaction request and storing the basic chain transaction data in the block of the basic chain, the method may further include: and acquiring transaction data from a locally stored parallel chain according to the basic chain transaction request for transaction processing of the basic chain, or feeding back the transaction data in a basic chain network node.
Accordingly, because the basic chain transaction request includes data of the parallel chain, for example, a block address of the transaction data is queried in the parallel chain, in the embodiment of the present invention, the basic chain network node may further obtain corresponding transaction data from the locally stored parallel chain directly according to the basic chain transaction request, and the transaction data may be used by a block generation node in the basic chain network to perform a transaction. That is, when the block generation node in the basic chain network processes the basic chain transaction request, the transaction data in the parallel chain network can be used for performing transaction processing. In addition, the basic chain network node can also feed back the transaction data acquired in the parallel chain in the basic chain network for other nodes to know.
In an alternative embodiment of the invention, the base chain is used to support data storage for an application platform and the parallel chain is used to support data storage for an application running on the application platform.
In the embodiment of the present invention, a base chain may be used to store data of an Application platform, where the Application platform is a server platform capable of supporting multiple Application functions, and the base chain stores and processes Application data and cache data of various APP (Application) management platforms, for example. Meanwhile, parallel chains can be used for storing data of various applications running on the application platform, for example, one parallel chain can store application data and cache data of one APP. The base chain may manage the creation of parallel chains, incentive mechanisms, and monetary operations across chains, among other things. For example, the base chain acts as an organizer of digital currency exchanges.
According to the embodiment of the invention, the basic chain transaction request comprising the data of the parallel chain is processed by acquiring the basic chain transaction request sent by the network nodes simultaneously participating in the basic chain network and the parallel chain network, and the basic chain transaction data is stored in the block of the basic chain, so that the cross-chain transaction request is processed by the network nodes simultaneously participating in the basic chain network and the parallel chain network, the association between the two block chain networks is established, the problem that the existing block chain technology is difficult to adapt to the requirements of various scenes is solved, and the block chain network can be matched with the requirements of more and more complex application scenes.
Example two
Fig. 2 is a flowchart of an implementation method of a blockchain network according to a second embodiment of the present invention, which is embodied based on the above embodiments, and in this embodiment, specific operations are given while processing the basic chain transaction request and storing basic chain transaction data in a block of a basic chain, or after: and executing the account intelligent contract in the basic chain transaction request, and changing the associated account data of the parallel chain network nodes. The embodiment mainly provides a case of processing account data of the parallel chain through the basic chain, and can be typically used for stimulating the creation and operation of the parallel chain by adopting digital currency of the basic chain. Correspondingly, as shown in fig. 2, the method of the present embodiment may include:
s210, a basic chain transaction request sent by a network node is obtained, wherein the network node participates in a basic chain network and a parallel chain network at the same time, and the basic chain transaction request comprises data of a parallel chain.
In an optional embodiment of the present invention, the method is applicable to a scenario when parallel chains are created, and specifically, the obtaining of a basic chain transaction request sent by a network node may include: acquiring a basic chain transaction request initiated by a parallel chain creating node, wherein the basic chain transaction request comprises deployment data of the created parallel chain, a specified output account and a set distribution rule.
The parallel chain creation node may be a network node that creates a parallel chain creation block, and the network node is also deployed with data of the basic chain, so that a basic chain transaction request may be initiated. The designated output account number may be an account number used to output digital currency circulated in the base chain to other account numbers. The allocation rule may be set according to which the parallel chain network allocates the basic chain elements, wherein the basic chain elements may be digital currencies circulated in the basic chain network. The specific content of the allocation rule can be set according to actual requirements, such as an average allocation rule, and the embodiment of the present invention does not limit this.
In the embodiment of the present invention, any one of the nodes in the basic chain network may serve as a parallel chain creation node to initiate a basic chain transaction request for creating a parallel chain created block, that is, the parallel chain creation node may use the content of the created block of the parallel chain as a transaction request for a basic chain, and request the basic chain network node to write into the block of the basic chain, so that the basic chain may supervise and trace back the created block of the parallel chain. The contents of the founder blocks of the parallel chain may be established with reference to the contents of the founder blocks of the existing block chain. For example, deployment data such as a consensus mechanism, an incentive mechanism, issued digital money, and a template of an intelligent contract written in the parallel chain may be written, and in addition, a corresponding designated output account number and a set allocation rule may be defined in a creation block of the parallel chain. And the creation block of the parallel chain can control the later operation of the parallel chain. Therefore, when the parallel chain is created, the initiated basic chain transaction request can specify the excitation rule of the nodes participating in the parallel chain establishment.
In an optional embodiment of the invention, the setting of the allocation rule may comprise at least one of:
for block generation nodes of historical blocks with set quantity in a parallel chain, distributing elements of a set numerical value basic chain according to a calculation contribution rule;
distributing basic chain elements to the network nodes distributed with the parallel chain elements according to the distribution proportion of the parallel chain elements in the parallel chain;
and for nodes in the parallel chain, setting the distribution of numerical basic chain elements according to an average rule.
The set number may be a value set according to actual requirements, for example, 10, 20, or 50, and the embodiment of the present invention does not limit this. The calculation force contribution rule can be artificially specified and used for measuring the weight value or the sequence occupied by the nodes providing the strength of the calculation force. For example, in the first 5 block generation nodes, the weighted values of the computing power provided by each block generation node are 0.1, 0.2, 0.3, 0.2 and 0.2, or in the first 5 block generation nodes, the computing power provided by each block generation node is sequentially from strong to weak: a block generation node 1, a block generation node 3, a block generation node 2, a block generation node 5, and a block generation node 4. The set value may also be a value set according to actual requirements, such as 100 or 200, and specifically needs to be adaptively set according to the total amount of the basic chain elements included in the basic chain, which is also not limited by the embodiment of the present invention. The assignment proportion of parallel chain elements may be formulated for parallel chain network nodes for assigning a proportion value of base chain elements. In general, during the operation of the parallel chain, a certain amount of digital money is awarded to the block generating nodes of each block, namely the digital money of the parallel chain is distributed. There is typically some attenuation as the number of blocks increases. When the basic chain elements are distributed, the corresponding proportion distribution can be carried out by referring to the distribution proportion of the parallel chain digital currency. The parallel chain elements may be digital currencies that flow in the parallel chain, which may be the same or different from the base chain elements. The averaging rule may be a way to evenly distribute all nodes participating in the parallel chain.
In this embodiment of the present invention, optionally, the set allocation rule included in the founding block of the parallel chain may include the following cases:
first, a basic chain element with a set value may be assigned to the block generation node according to the number of block generation nodes in the parallel chain and the calculation power contribution rule. The basic chain network node can query the block data in the locally stored parallel chain by executing the intelligent contract associated with the parallel chain to acquire the block generation node information in the parallel chain. For example, if a bitcoin is used as a basic chain element, and when the number of block generation nodes in the parallel chain network reaches 10, 100 bitcoins can be allocated according to the strength of the calculation power provided by the 10 block generation nodes. If the weighted values of the computational power provided by the 10 patch generation nodes are 0.05, 0.1, 0.15, 0.1, 0.2, 0.05, 0.1, 0.05, and 0.1, respectively, 5, 10, 15, 10, 20, 5, 10, 5, and 10 bitcoins are allocated to the 10 patch generation nodes, respectively.
Secondly, the basic chain elements can be distributed only to the network nodes with the parallel chain elements in the parallel chain network according to the distribution proportion of the parallel chain elements in the parallel chain. Illustratively, node 1, node 2 and node 3 in the parallel chain network have 5, 10 and 15 bitcoins respectively, and the distribution ratio of the parallel chain elements of the three nodes is 1:2: 3. The bitcoins in the 120 base chains may be allocated according to the allocation ratio of the parallel chain elements of the three nodes, and then node 1, node 2, and node 3 are allocated 20, 40, and 60 bitcoins, respectively.
Of course, the nodes in the parallel chain may also be directly assigned the basic chain elements with set values according to the average rule. For example, there are 15 nodes in the parallel chain in total, and the bitcoins in the 300 base chains may be equally allocated to 15 nodes, each node being allocated to 20 bitcoins.
It should be noted that the assignment of the basic chain elements and the parallel chain elements in the embodiment of the present invention may follow a decreasing rule.
And S220, processing the basic chain transaction request, and storing the basic chain transaction data into a block of the basic chain.
The above-mentioned assignment to the basic chain elements may be performed once or in multiple times, and may be specified by the intelligent contract in the basic chain transaction request. The execution of the intelligent contract may be performed as traced back.
S230, receiving a notification transaction request sent by a parallel chain network node, and searching the basic chain transaction request in a basic chain according to an intelligent contract in the notification transaction request; or backtracking and searching the basic chain transaction request from a history block of the basic chain.
The notification transaction request may be sent by the parallel chain network node to the basic chain network node, and is used for notifying the basic chain network node of a request for performing a cross-chain service. It should be noted that the notification transaction request is generated by the network node according to the deployment data in the basic chain. The network node may generate the notification transaction request according to the provisions in the intelligent contract in the parallel-link network. For example, when 10 blocks are added in a parallel chain, a notification transaction request may be initiated to the underlying chain network node.
In an embodiment of the invention, a network node may send a notification transaction request including an intelligent contract to an underlying chain network node. After receiving the notification transaction request, the base chain network node may search for a corresponding base chain transaction request in the block data of the base chain. Or, the basic chain network node may directly trace back and search the basic chain transaction request in the locally stored history block, for example, the corresponding basic chain transaction request is searched by process triggering or setting a search rule.
And S240, executing the account intelligent contract in the basic chain transaction request, and changing the associated account data of the parallel chain network nodes.
The account intelligent contract in the basic chain transaction request can be created by a parallel chain creation node and added to a block by a block generation node of the basic chain for execution, so as to bind the parallel chain. The contents of the account intelligence contract may specify any operations related to the parallel chain, such as: how to distribute incentive currencies among nodes of the parallel chain, the amount of currencies that can be distributed, rules for distribution, and the like. The associated account may be a private account of the network node for depositing digital currency of the base chain or parallel chain.
In the embodiment of the invention, when the basic chain network node executes the account number intelligent contract in the basic chain transaction request, the associated account number data of the parallel chain network node can be changed according to the specific provisions in the account number intelligent contract.
Specifically, the account number intelligent contract in the basic chain transaction request is executed, and the operation of changing the associated account number data of the parallel chain network nodes may be further detailed as operations S241, S242, S243, and the like.
And S241, executing the account intelligent contract in the basic chain transaction request, and acquiring the associated account of the parallel chain network node from the locally stored parallel chain.
In the embodiment of the present invention, if the basic chain network node, that is, the block generation node in the basic chain, stores the parallel chain at the same time, each block in the locally stored parallel chain may be queried when executing the account number intelligent contract in the basic chain transaction request, so as to obtain the corresponding associated account number information in the block data of the parallel chain network.
It should be noted that the execution time of the account number smart contract in the basic chain transaction request may or may not coincide with the creation time of the account number smart contract. That is, the account number smart contract in the basic chain transaction request may be executed immediately when the account number smart contract is generated, or may be executed according to the rules such as the number of blocks in the parallel chain network or the set time period.
And S242, generating a basic chain element transfer contract, wherein the basic chain element transfer contract is used for transferring basic chain elements to the associated account according to a set distribution rule in an output account specified in the account intelligent contract.
The basic chain element transfer contract may be a rule or the like formulated for outputting the basic chain element to the associated account of the parallel chain network node.
In the embodiment of the present invention, after acquiring the associated account of the parallel chain network node, the basic chain network node may generate a corresponding basic chain element transfer contract, which is used for transferring the corresponding basic chain element to the associated account of the parallel chain according to a set allocation rule in an output account specified in the account intelligent contract.
And S243, transmitting the basic chain element transfer contract in a network node of a basic chain to request the network node of the basic chain to verify the transaction in the basic chain element transfer contract according to the locally stored parallel chain.
In the embodiment of the invention, after the block generation node in the basic chain network completes the transaction processing of the basic chain element transfer to the associated account, the corresponding transaction data is added into the block, and the block is sent to other nodes to request the confirmation of the block. After receiving the block, the other network nodes may verify the validity of the transaction in the underlying chain element transfer contract according to the locally stored parallel chain. For example, it is verified whether the set allocation rule is correct, whether the diverted account is consistent with the node account recorded in the parallel chain, and the like. Therefore, the block generation node is ensured to correctly execute the account intelligent contract.
It should be noted that fig. 2 is only a schematic diagram of an implementation manner, and there is no precedence relationship between S220 and S230-S240, and S220 may be implemented first, and then S230-S240 may be implemented, or both may be implemented in parallel.
In a specific example, it is assumed that there are 3 independent blockchains in a blockchain network, including a base chain (Root chain) and two parallel chains, i.e., an a chain and a B chain. When the x account of the chain A needs to exchange the object C on the chain A with the object D of the w account of the chain B, the exchange can be completed through the Root chain. The method comprises the following steps:
first, the a-chain x account initiates a first transaction request of the a-chain, and transfers the object C to a first coordinator account of the Root chain, where the first coordinator account may be a temporarily designated or default common account.
The B-chain w account initiates a second transaction request of the B-chain, and transfers the object D to a second coordinator account of the Root chain, where the second coordinator account may be a temporarily designated or default common account. The first and second coordinator accounts may be the same or different.
When the network node of the A chain and/or the B chain initiates the first transaction request and the second transaction request, the network node can also simultaneously initiate the transaction request of the Root chain, and the Root chain is required to monitor whether the object C and the object D are transferred into the first coordinator account and the second coordinator account through an intelligent contract.
If the transfer is carried out, a third transaction request of the chain A and a fourth transaction request of the chain B are initiated, the object C is transferred to the account number w, and the object D is transferred to the account number x. Or initiating a fifth transaction request of the Root chain, transferring the object C to the w account, and transferring the object D to the x account.
The Root chain can be used as a coordinator of the cross chain and provides cross chain service. It should be noted that any chain with public confidence can be used as the basic chain. In the process, the function of article exchange between the chain A and the chain B is ensured, and the problem that the chain A and the chain B are not trusted mutually and the direct transfer of articles can cause fraud is solved. The above-mentioned article may be any, such as digital money or electronic articles.
By adopting the technical scheme, the basic chain transaction request is processed by acquiring the basic chain transaction request sent by the network node, the basic chain transaction data is stored in the block of the basic chain, and then the account number intelligent contract in the basic chain transaction request is executed at the same time or according to the set execution time, so that the change of the associated account number data of the parallel chain network node is realized, and the block chain network can meet the requirements of more and more complex application scenes.

Accordingly, as shown in fig. 3, the method of the present embodiment may include:

S330, if the basic chain transaction request is an update transaction request of parallel chain deployment data, changing the parallel chain deployment data in each parallel chain network node according to the update transaction request.
The update transaction request may be a request for changing data deployed in a parallel chain network node, for example, changing parameters in a parallel chain, a module of an intelligent contract or an encryption algorithm, or forcing to eliminate the parallel chain.
In the embodiment of the present invention, if a network node needs to change parallel chain deployment data, a change requirement may be sent to a basic chain network as a basic chain transaction request. After the block generation node in the basic chain network receives the update transaction request of the parallel chain deployment data, the parallel chain deployment data in each parallel chain network node can be changed according to the specific content of the update transaction request.
For example, a block generation node in the base chain network may process an update transaction request in a proposal-vote manner. Specifically, the base chain network node may initiate an update transaction request that includes the modified content information of the parallel chain deployment data. Meanwhile, the basic chain network node also needs to specify relevant parameters of proposal-voting process, for example, after a set proportion (such as 2/3) of nodes in the basic chain network agree to the request of update transaction, the deployment data of the parallel chain is allowed to be changed; the expiration time of the vote, e.g., 10 minutes; and frozen funds as security funds, etc. Then, the basic link network node may collect voting results of other nodes in the basic link network, and determine whether to process the update transaction request sent by the network node according to the voting results. When it is determined that the update transaction request can be processed according to the proposal-vote manner, a corresponding update transaction request can be sent again to change the parallel chain deployment data.

The embodiment of the invention processes the basic chain transaction request comprising the data of the parallel chain by acquiring the basic chain transaction request sent by the network nodes participating in the basic chain network and the parallel chain network simultaneously, and stores the basic chain transaction data into the block of the basic chain. If the basic chain transaction request is an update transaction request of parallel chain deployment data, the parallel chain deployment data in each parallel chain network node can be changed according to the update transaction request, the cross-chain transaction request is processed by the network nodes simultaneously participating in the basic chain network and the parallel chain network, the association between the two block chain networks is established, the problem that the existing block chain technology is difficult to adapt to the requirements of various scenes is solved, and the block chain network can be matched with the requirements of more and more complex application scenes.
